Thanks, and I just tried to order their DIY purifier for $45 but they charge $60 for shipping! I kid you NOT, LOL! I have to make a video of my initial online interaction/conversation with them - Folks would NOT believe their reasoning for why they think their cheap DIY is as good as IQAir. I told my 19 year old and he laughed out loud... Thanks! 😃

Just watched it till the end and it really was hilarious 🤣

@@AirPurificationEducationcould you possibly include the link about the diseases you mentioned that are related to air partivlrs? 🙏 thank you so much

Folks online pretending to be Mother Teresa while they are talking a bunch of crazy, LOL!😆 @@IntegrityMeansAll

I am sure there is a lot more research out there on this issue and I'll probably make another video on it in the future but here are some links/sources I used for the video "Is Your Air Quality KILLING You?

Wow... sounds like you may have brought up some good points. I think you need a KZfaq channel! LOL! JK... but thanks for the input - I do appreciate it! 👍

I don't have much experience with DIY solutions but you may wish to ask this guy - The 3D Handyman. As he has a bunch of different DIY builds and he sells some of them, as well: www.youtube.com/@The3DHandyman

I spend a lot on restaurants, too - good tasting food is a staple of my happiness :)

Hey Joseph, YES! 100% 👍 1) I spent the past few months improving my education on "all things air purification" so I could eventually feel more confident that I could "rate" various units against each other without using "Digital Testing Sensors" as I found out they are not accurate. My original plan was to use the testing devices to help decide which units have superior filtration however, much to my surprise and disappointment I have come to the conclusion the results would not be accurate. So, I've been trying to figure out ways to "rate" the units with other measurables. And I think I am ready to go, now. 2) Next video: I will be doing a review on the very popular Coway 400 and then - Next video: I will compare the IQAir, Austin Air, Aeris and Coway all against each other... Then we will have a foundation of some of the better particulate filtering units in the US market, at least. Plus, they are all units I am familiar with and have consulted on for years... so, I know they are at least "good" units. 3) And then I will start reviewing some of the lower-priced units and trying to explain how they all compare to each other. There is so much misinformation and flat-out lies in the industry that it has been challenging for me to get to a knowledge point where I feel like I can do the topics justice for people and really explain things in a proper manner. It won't be perfect but it will be pretty good, I think. 4) What unit(s) in particular are you interested in? I am about to go on a "purchasing spree". That's what credit cards are for, correct? LOL! I'm currently making a list that looks like this: 1. Winix 5500, 2. Coway mighty 3. Clarion, 4. Levoit 5. Blue air 6. Air Doctor 7. Smart air fan Thanks for the suggestion! 😃

​@AirPurificationEducation is winix 5500-2 better than airdoctor ad3000?

IDK for sure, as I have never worked with the Air Doctor units but I can definitely see how the dirty air is escaping around their filters in online videos... I do have an older Winix 5500 and will be getting the newer version soon. If I had a small room about 200 sq. ft. I'd probably go with the Winix for the price and if I had to guess I think they may very well filter similarly. There is NO way the Air Doctor or the Winix are getting all the particles down to .003 microns like they claim on their websites. That is just not happening. Thank you! 👍 @@prtbone78 👍

@AirPurificationEducation thanks again for the feedback. But for 200 and get almost 4 times price point airpurifier. Thought was a no Brainer maybe ill just pick up 2 more winix ones then. Which newer winix you looking at and recommend?

I'm just getting the updated Winix 5500 - I have one from 7 years ago but I'm gonna compare the differences. I also just got a Coway Mighty, Clarifion, and Levoit today - and have a Blueair and Aroeve coming tomorrow, as well... so I'm gonna be busy doing reviews and figuring out how to compare them to each other in the coming weeks. Should be fun. 😃 Eventually, when the dust settles (pun intended) - I'm gonna get the Air Doctor and take a good look at that, as well. @@prtbone78

Thanks for the info. - I recently purchased a Blueair 211 that I'm running and I plan to do a review on it in the future. Yeah, that is interesting - the prefilter will help prevent the Carbon and HEPA filters from clogging so... IDK exactly why they would not be present but perhaps they feel they can do without them for some reason. Thank you!👍 Happy Holidays!😃

Thank you!😃

Me too

Glad you enjoyed it😃@@IntegrityMeansAll

Thank you for your inquiry. 1) I don't know a lot about the ionization issue but I do know that the best air purifiers I've worked with don't use any ionization. And my knee-jerk reaction is I don't really trust them. 2) IQAir published an article about 6 years ago on Ionizers. IQAir (Switzerland) is one of the best air purification manufacturers in the world and has been around for over 50 years. I run their HealthPro Plus in my family room and I think it is one of the best mass-produced air purifiers in the world for particle filtration. And I always thought if ionization was a good thing - they would implement it in their product lines.: www.iqair.com/us/newsroom/ionic-air-purifier-what-you-must-know-before-buying 3) Austin Air (an American manufacturer - and I have 3 of their air purifiers) also published an article about ionizers, as well - in the past year. And it appears the EPA - that's the US Environmental Protection Agency is telling US consumers they may produce ozone which is bad.: austinair.com/a-review-by-the-epa-warns-against-esp-and-ionizer-air-purifiers/ 4) Oransi (another US manufacturer) wrote an article about ionizers, as well, which you may find useful: oransi.com/blogs/blog/ionic-air-purifiers-vs-hepa-air-purifiers 5) I purchased a Clarifion air ionizer 2 weeks ago to do a review on it as they are currently running ads on KZfaq and they have made some very nice, well-done videos but... I don't think their solution is as good as HEPA filters and carbon. I'll eventually do a review of it. So, I currently would not use an air purifier with ions or an ionizer but I will be doing more research on this in the future. Thank you!👍

@@AirPurificationEducation Thanks a lot :) I probably stop looking for ionizer and try to make more research about air purifier with HEPA filtration. Like josephk.9567 wrote, I would also look forward for more air cleaners which are selling in Europe

Ionizers remove a very small amount of the total particles in a room, but they do charge the air in the room and negative ions have been reported to make people feel better, but they don't remove particles anywhere near as well as a filter. BlueAir I think uses both negative ionization and a filter together.

If you are asking about the IQAir HealthPro Plus - the answer is that it is one of the best mass produced consumer air purifiers for particles in the world. It also does a good job on the most dangerous and plentiful particles in the air we breathe - the Ultrafine Particles. It filters 99.5% down to .003 microns which is elite performance. I currently think it may be the 2nd best consumer air purifier for UF particles on the entire market. Over 99% of the so called "HEPA" air purifiers in the market do NOT actually filter at a HEPA level. The IQAir HPP actually filters BETTER than HEPA. Here is a video explaining why over 99% of the HEPA Filters don't actually filter at a HEPA level: kzfaq.info/get/bejne/i9hmfZmb1q-pnY0.html Here is a short review on the IQAir HPP: kzfaq.info/get/bejne/hpeCm6iVxra2haM.html&ab_channel=AirPurificationEducation The unit itself probably costs IQAir about $150 to make and they sell it for $899. I don't know for sure - I'm just guessing. I worked for a contact lens company years ago and it cost $2 to make the lenses and they sold them for $84. I also worked for a oil purification company years ago and it cost about $1 to make the filters and they sold them to dealers for $42. So, all manufacturers are going to have a markup price for profit... I don't know if I'd call it "Inflated Price tag" - these companies need to make money on their products to stay in business and pay their employees, pay for advertising, trade shows, research and development, new equipment/robotics for new products, packaging, warehousing, etc. A lot goes into manufacturing and distributing a product - especially a product that needs to perform at an elite level. And it all costs a lot of money to run the company and pay for everything. Hope that makes sense. Thanks!👍

@@AirPurificationEducation I appreciate the fast and honest response, and as usual it the consumer to blame which was my initial thoughts. They'll only charge what folks are willing to pay even if the product is 5x cheaper to make. We as consumers need to change and demand fair pricing. Especially something that would be so beneficial in all house holds but due to greedy business practices it's a niche item only afforded by the privilege. I don't feel it's right for only someone who has the means to burn near $1000 usd be afforded the right to breath clean air, it's madness. All that said thank you for all you do, you've really educated me on the topic appreciate you.

The HPP has been around for over 24 years and it was a groundbreaking air purification solution - still to this day - barely ever matched in performance by any company. Which is amazing when we consider how many different air purifiers have been made in the past 24 or so years... literally thousands. In 2015, Aeris came along with the 3 in 1 and they actually filter particles even a little bit better than the HPP. And they came to the US market selling their 3 in 1 unit with a retail price of $999. iRobot purchased them 2 years ago and was selling the units at $750 (the price decrease may be due to the fact that Aeris was manufacturing the units in Switzerland and iRobot very possibly started to have them made in China with less overall costs). Aeris also had a smaller unit called the Aeris Lite - that filters the particulates just about as well as the 3 in 1 but it retailed for about $399 and it was for smaller spaces/bedrooms. Sometimes you could get it on sale for $349.00 - which was AMAZING for such elite particle filtration. iRobot seems to have stopped the manufacturing of the Lite unit which is a SHAME - as it was an amazing solution - esp. for the money. And it did provide elite particle filtration at a much more reasonable price. I agree, it is sad that folks have to pay so much for great air quality solutions... that said, I do think - over time - we will eventually see more elite air purification solutions appear in the market for more reasonable prices. Competition, better technology, etc. will eventually drive the prices down over time. I think this happens in most industries... We'll see... Thanks! @@blackstars3720

Do you like it? I have a Nilfisk GD930 and I paid $550 for it over 10 years ago but it now retails for over $700.

@@AirPurificationEducation Well it's the best vacuum I've had but also the first I've bought myself since all other have been cheap hand-me-downs from relatives, so it's hard to compare (I was a poor student back then).

In the last company I worked in - we had about 15 different Miele vacuums in our showroom... And I gotta say - they were some really nice and slick vacuums. Very impressive features. I can totally see why some folks would gravitate towards them. Then one day 2 of them went missing - and those things cost over $600.... so, I think we shut the showroom down at that point in time, LOL! The Nilfisk I have is ugly and doesn't have any nice features whatsoever, but it is supposed to filter well. Thanks! @@terrylyn

If you have large particles in your environment - then you probably also have small particles, as well. The ultrafine particles represent 90% of the particles in the air and are the most dangerous ones to humans, as well. That said, if you are only interested in filtering larger particles - then yes, you can use a MERV 13 filter and a fan - or whatever and a fan... - just as long as folks realize they are only filtering the larger, less hazardous particles. Plus, not helping with VOCs/chemicals, either.

Airpura makes some good units for sure - and they are especially strong on the carbon/VOC side of things, IMO. Can you please say why you think the P714 would be better for you than the IQAir HPP? Thank you! 👍

@@AirPurificationEducation I’d like to place a unit with heavy duty VOC filtration near the kitchen and the Airpura p714+ with 18lbs of carbon really stands out to me. On top of that, its H14 Super Hepa with an optional ULPA filter upgrade gives me that peace of mind. What are your thoughts on photocatalytic oxidizer for enhanced chemical filtration, and UV-C? Id like an expert opinion.

I would not say I am an expert - I would say I am more of an "Air purification consultant" and consider myself a "student" of this industry. That said, I LOVE Airpura's carbon solutions and think Helder, the owner - may actually be an "expert" on carbon solutions. I've talked with him about their carbon solutions a few times in the past and I was very impressed with his knowledge levels, for sure. + He seems like a trustworthy man and I think their company takes care of their customers/treats them well. 1) That said, I know they have the Super HEPA and ULPA options but I am not 100% sure they actually filter at these levels... I'd need to see legit 3rd party testing results to feel confident that they actually perform at these levels, for sure. And if they actually perform at these levels 6 months after running in the real world when the filters are dirty and you run the units on higher CFMs - which is the real Acid Test, IMO. All that being said: Even if they don't filter at those elite levels... - I do feel their regular HEPA solutions do filter the particles at a good level - but I just don't know if the Super and ULPA actually can do what the IQAir HPP and Aeris 3 in 1 can do. They are both EN 1822 certified and that somewhat proves to me that they really are elite at particle filtration. 2) I am going to be learning about photocatalytic oxidization in the future as it is on my list to "get up to speed" on but unfortunately, I do not know enough to talk about it at this point. 3) UV-C: In general, I have not really been a fan of UV-type solutions and I am not sure how much value they actually add to air purification solutions. Some of the best filtering solutions on the market do not possess it. IQAir said years ago that the air in air purifiers moves by the UV light too quickly for them to really make a significant difference. So, I have never cared if any of my solutions possessed it - nor have I ever recommended it to any of my customers. That said, the air purification industry is dynamic and constantly changing so it is possible that Airpura has found a way to implement it better in their solutions than others. I am open-minded and I'll never say never. But in the past - I have not cared about it. Thank you! 😃 @@xdean

@@AirPurificationEducation I really appreciate your honesty and insight. Im an air purification junky lol and Im learning something new everyday. Wow I totally missed the EN1822 for Airpura units. How crucial is the missing EN1822 certification? Aeris Aair Pro 3-1 is definitely on the radar now.

1) How crucial is the missing EN1822 certification? It is good if it's legit but I think some companies may be getting EN1822 tested and then "interpreting" the test results for us to make their units look better than they actually are... and/or I think it is possible some are gaming the system from a testing standpoint somehow. I need to look into it further as I saw a company say they were EN 1822 certified and they claimed that their air purifier filtered 100% at .003 microns and I HIGHLY doubt that is occurring in the real world. 2) Unfortunately, the Aeris 3 in 1 is only available in Japan right now, from what I understand - IDK why iRobot doesn't have it available in N. America or EU. Thanks!👍@@xdean

Nope, the GC unit has more carbon so it filters more VOCs and odors but the IQAir HealthPro Plus filters particles better. Please take a look at the specs on their website: IQAir GC GC - 99% at .3 microns (not even HEPA level which of course, is 99.97% at .3 microns). And 95% at .003 microns www.iqair.com/products/air-purifiers/gc-multigas IQAir HealthPro Plus: Total System Efficiency of 99.97 at .3 microns, 99.5% at .003 microns: www.iqair.com/products/air-purifiers/gc-multigas So yeah, as stated, the HPP filters particles better than the GC. Thanks!👍

Thank you for your question. 1) I sold IQAir units to customers even when the company/dealer I worked at was cut off from selling them. Meaning, if I felt the IQAir HPP was the best solution for a customer - I would tell them to purchase it even after we didn't sell it anymore and my company and I would not make any money on it. Because I am a consultant and I provide the best solution for my customers regardless of my personal gain or not. I directed many customers to buy the IQAir HPP after we couldn't sell them anymore. I explain this in a video when a guy on TikTok asked how much money I make on the IQAir HPP (about a year ago). Starting at 1:25 of that video: kzfaq.info/get/bejne/gb9llpCrrZbTloE.html&ab_channel=AirPurificationEducation Also, the #1 unit currently on my "Best Air Purifier list" is the Aeris 3 in 1 and it has not been available in the US for a couple of months now... and no one knows when it will be coming back. Some say it won't be available in North America again. I will still put it at #1 on my list - regardless. No other KZfaq channel has Aeris at #1 in their best air purifier videos, that I have seen... and I don't think any will put it there for the foreseeable future because: A) Most don't know how good it is and B) it is currently not available so they won' t make any money on it. 2) Most consumers totally underestimate the level of engineering and precision it takes to make an air purification solution filter at a True HEPA level. Most all the manufacturers on the market say their units are "HEPA" air purifiers but over 99% of them do NOT actually work at a HEPA level. I explain why in this video called "HEPA Filters - Are They All the Same?": kzfaq.info/get/bejne/i9hmfZmb1q-pnY0.html&ab_channel=AirPurificationEducation 3) "however what if someone bought the three IQair filters and created the same fan-DIY solution i.e. attach prefilter to fan attach to carbon filter attached to heal filter. Would be pretty simple to do to be honest, just lay them and secure them on top of one another, then you could case it in with 4 pieces of thin flat wood from. Aside from the fan shape, which I expect is negligible, seems like you would have a similar air purification results at 1/3 the cost of buying the machine" Again, most consumers have no idea how difficult it is to make an air purifier actually filter at a HEPA level. You have to create pretty much perfect seals between the HEPA filter and the internals of the air purifier so dirty air does not escape around the HEPA filter. Over 99% of the air purifiers do not have good enough seals inside their units. I'll make a video on this in the next couple of months - showing the difference in seals between multiple different air purifiers. The high level seals on the Elite units vs. the "less than perfect" seals on the "also ran" units. 3) You said, "Aside from the fan shape, which I expect is negligible" LOL! NO, it is NOT that simple - there is such a thing as "fan engineering" and the IQAir HPP and Aeris 3 in 1 have specially designed fans. I've spoken with an expert fan engineer in the past and all he does is figure out how to make his companies fans produce more CFS (with as little energy, as possible) and have those CFMs spread uniformly over the filter media - NOT an easy thing to accomplish - it takes engineering expertise. And he said most ALL the manufacturers lie about how many CFMs their solutions actually produce. They typically produce less CFMs than what is stated in their specs. There is much more to this, as well... anyhow, I think you get the picture. Hope that makes sense - thanks!👍

Merv 11 on an old box fan is about 80-95% just as good as an IQ Air but it's much louder and ugly and won't filter any gases, but carbon can be problematic since it can also release the same hazardous gases that it filtered and you never know when this might happen. Carbon also clogs the HEPA filter since it breaks into microscopic particles itself and is it's own pollution. Leakage doesn't matter since the whole room around the filter is the same as one big leak, what matters is how much air is moved through the filter per time unit, you can filter more with a lower filter rating if the fan is moving more air. It takes about 15 minutes to an hour before most of the particles in an average bedroom are removed by an IQ Air type machine running on highest speed. There are even cases where gases can condense in realtime into particles and create a situation where even an IQ Air can not filter more than about 90% of the particles because the gases keep condensing into particles faster than they are being filtered.

Also, nobody tests if the carbon filters are harmful, they might actually be more harmful due to microscopic particles of carbon flaking off in the high wind of the fan and the smallest particles will make it through a 99.97% efficient HEPA filter and go into our lungs and body.

Also, some say that HEPA filters get more efficient with use, not less efficient, this is different than being clogged by large particles.... so you should be able to vacuum out a HEPA filter and keep using it for along time and only replace it to be sure it doesn't have mold or similar on it.

Look up the info from NASA, they tested the HEPA filters and published a study. (link edited to pass the comment filter) "How do HEPA filters work? It is widely believed that HEPA filters are only capable of capturing particles sized 0.3 μm or larger. However, this belief is based in part on an incorrect understanding of how HEPA filters work. The fact is that particles of around 0.3 μm are the hardest to catch (Perry J.L., Agui J.H., Vijayakumar R. Submicron and Nanoparticulate Matter Removal by HEPA‑Rated Media Filters and Packed Beds of Granular Materials. NASA/TM‑2016‑218224 ntrs nasa gov archive nasa casi ntrs nasa gov 20170005166 pdf1​); for this reason, that size is used to measure the effectiveness of HEPA filters. Much smaller nanoparticles are in fact easier to catch. But why is this so? For larger particles, the HEPA filter acts like a net as we would expect. Particles greater than 0.3 μm in size simply cannot get through: either they do not fit through the holes or they hit the filter fibers due to inertia. For smaller particles, on the other hand, it would seem logical that they can simply go through the holes. However, this is not the case. The tiny mass of particles less than 0.3 μm means they do not fly straight; instead, they are bounced off other molecules as they collide with them and thus move in completely random patterns. As a result, they hit the filter fibers and then remain stuck in them. This is the principle of Brownian movement." - Hamilton Medical

Thanks for letting me know. I currently do not know which ones are the most accurate but I'll eventually get into it- thanks!

I found tvoc monitor better for regulating ventilation.

1) “ The small filter can be just as good at filtering particle as the IQ Air and probably is about the same for a small room, because the main thing is fan volume of air and size of filter (not depth for particles.)” ***I’ve sold many different air purifier brands and the IQAir HPP has almost always received the best reviews from customers in my experience. I’ve dealt with many customers through the years who tried out numerous different air purifiers before settling on the IQAir HPP and many have stated that it enabled them to breathe better than any other air purifier they’ve tried in the past. And it was pretty rare for a customer to say the opposite (going from a HPP to a lesser unit). So, I do believe it filters particles much better than 99% of the solutions on the market. 2) “Having a carbon filter in with the particle filter is not that great of an idea because it actually releases carbon and since the IQ Air is impregnated with other chemicals, it also releases other chemical particles into the back of the HEPA filter and also into the air since the HEPA filter is not 100%.” ***Anything is possible… it may/may not be an issue. Plus, there are many different types of carbon out there. That said, the HPP is one of the best-sealed mass produced units on the market so, I would think it would possibly be less of an issue for this particular unit vs. other brands/units. 3) “However, carbon filters (any and all even the big Airpura carbon filters) only filter about 9% of gases/VOCs, not more.” ***I currently find “only a 9% success rate” hard to believe as I’ve successfully used a HPP for new paint fumes in an office room. And I’ve had many customers successfully use various carbon solutions for very intense VOC environments like professional car painting and diesel fuel VOCs. I had a guy who had school busses sitting in front of his home running for 20 minutes every morning and he said he was getting “diesel fuel odors” in his family room.” The school would not reroute the busses so he said he was forced to sell his house. His last ditch effort to possibly stay was purchasing an IQAir GC unit with 12 lbs. of carbon. He called back 2 days after getting it and said it completely solved his problem and he wasn’t planning on selling his home anymore. In this instance, I do believe the carbon absorbed more than 9% of the VOCs in his environment. A 9% success rate would not have been good enough for his situation, IMO. 4) “I still think the IQ Air is great because it's so quiet, but it's no better at filters than the old round Honeywell HEPA filters and only about 5-10% better than a Merv 11 taped to an old dirty box fan.” *** As stated before, I’ve dealt with many customers through the years who tried out numerous different air purifiers before settling on the IQAir HPP and many have stated that it enabled them to breathe better than any other air purifier they’ve tried in the past. 5) “Then you have the time it takes for a filter to work, it takes a long time, so if you are relying on it to filter out really dangerous substances you will already be dead by the time it starts to work, because there is so much more air volume in a typical room or space than a single filter can filter in a short amount of time.” ***OK, that was pretty funny, LOL! I haven’t had anyone die before the air purifier started to work but I’ll never say “never”, LOL!😆 6) “So filters are good for supplementing your air and improving it but they are never going to be perfect and the best solution is to live and stay away from any known sources of air pollution.” ***Agreed 100%! Hawaii here we come! 7) “You can use PurpleAir as a good estimate to see the pollution in different areas of the world.” ***Maybe - IDK - I currently don’t have a lot of confidence in air quality sensors but I’ll be learning more about them in the future. The last 2 reviews I saw for the Purple Air were unfortunately, very poor - and that didn’t increase my confidence in these solutions, in general. Thanks for the post! 👍

@@AirPurificationEducation CR (Corsi-Rosenthal) box provides better value for clean air.

@@MrUncleBob Thanks for the comment. I think we would need to define what "better value" and "Clean air" exactly mean. And it will probably depend on the specific application and the other units that would be options. I currently think a CR box is probably a very good value to "dramatically Improve" the air quality in a woodworking shop environment vs. other available options. But, if we purchase good quality 3M filters for it - there are other inexpensive air purifiers which will filter better for a similar price/cost of ownership for other applications like a bedroom for dust, etc. So, I think we'd need to look at it on a case by case basis. Thanks! 👍

Thank you for your comments! 1) The Inkbird may be decent to provide you with a general idea of the PM2.5/10. I just don’t want people to see “Good Air Quality” on a sensor and simply assume everything is perfect. For example, I just had 4 air quality monitors in a Hotel last week that said the air quality was “Good” but I simultaneously took some mold samples. And today is day 5 and there seems to be a lot of mold activity in the petri dishes. I’m gonna mail them away for professional analysis but… the 4 monitors are probably not protecting folks from moldy environments… I’m thinking. 2) It is very hard for a monitor/sensor to test for the correct levels of particles in a space and esp. smaller particles, IMO. I think the accuracy is affected by temp., humidity, and airflow speeds + I’ve heard most of the sensors are cheaply made in China. And the EPA says the monitors seem to be less accurate over time. In addition, the monitors currently on the market are not good for testing for Ultrafine particles (.1 to .003 microns) which are the most abundant in our air and the most dangerous to our long-term health. So, I just want people to realize some of the limitations of their air quality monitors. 3) I’ve also heard that it is harder for monitors to accurately test VOC levels than particles. That said, CO2 may possibly be an easier thing for monitors to accurately test for, IDK… So perhaps, your Inkbird is somewhat accurate with that… I don’t know much about it and want to learn more about this in the future. I think Health Inspectors have a fantastic future. 👍 Happy Holidays! 😃

@@AirPurificationEducation Thank you for the respnse, sir. yeah i was gonna say, if u have a RCS u can send it to a lab and actually get CFU/m3 but obsiously that kind of thing is done by a health inspector. and probably isnt cheap could be way differrent in the states, as im canadian, but have you ever thought of sharing your work with health inspecters? if you found something here and called a health inspecter office with ur data and explained the situation they r probably, more likely than not, the people who would help you. as they will investigate further, perhaps using higher quality tests if the deemed necesary also might be the ones who tested the hotel(although they usually only do these kinds of tests when there is mold overgrowth ect. so maybe the safety they r referring to is just their generic inspections which may or may not have been as thorough as what u are doing.

1) I am using www.Evvivasciences.com for my mold kits. 2) I got 10 petri dishes for $45.00. and I will be sending in 2 of them to EMSL Labs. emsl.com/Locations.aspx?laboratoryid=49 3) It will be $65 per dish for them to analyze them and provide me info. so $130 total for 2... 4) I have spoken to many people through the years who became sick from mold in the past. Many of them become MCS - Multiple Chemical Sensitive (esp. females). And depending on their level of MCS - it can be extremely debilitating... can't keep a job... can't leave the house... get terrible migraines, go to multiple mainstream doctors who don't understand their condition and spend thousands of dollars with no relief. Some of these people are suicidal and I've had a few actually cry on the phone during our conversation. If they are very chemically sensitive their lives can be horrible and devoid of any happiness or joy. 5) I've also spoken to many people through the years who told me they had mold in the apartments they were renting. The landlords will most often either ignore it or get some unqualified person to throw some Clorox on the mold. 99% of the time they will NOT spend the money to get the mold cleaned up professionally/correctly as it costs a lot of money (mold remediation can cost thousands and even tens of thousands as you probably already know). My neighbor in a 2,000 sq. ft. (185 sq. meters?) townhouse had a $30,000 mold remediation job completed last year. It is no joke. 6) I stayed at a hotel last week that I am familiar with. I have stayed at this particular hotel (Best Western) in Raleigh, North Carolina on several occasions and I noticed that when you walk in the front lobby there is an overwhelming, super strong, chemical smell. My son also said it is super strong. It is not a pleasant odor, at all. You can also smell this chemical to a lesser degree in the elevators and stairwell. The building is over 40 years old and I am guessing they have mold and they are trying to "mask" the musty moldy odor with the strong chemical. The bottom of the hotel is mostly below the ground on the side of a hill which makes it much easier for them to have a moldy problem (it is like the hotel sits on a large half basement). 7) I was at another hotel in Pennsylvania a year ago and you could see where they actually painted "Over" the mold on the bathroom ceiling. This is how I think the vast majority of hotels deal with mold. Paint over it in the rooms and maybe even mask the musty smell with chemicals if it is strong. These are obviously bad options. 8) The US hotel industry is projected to achieve 1.3 billion occupied room nights in 2023 and there are 2.1 million people employed by the hotels. 9) These employees are at significant long-term health risk if they are working in moldy environments for prolonged periods of time (much moreso than the customers who only stay a few nights), IMO. That said, I NEVER get sick but I am now battling a sore throat which may/may not be related to the hotel stay from 3 days ago. 10) I am very interested to see what the lab says about the 2 mold samples. I put one in our room and one in the lobby where the terrible chemical smell is. I used 2 air quality sensors in each space and they both said, “Good Air Quality” LOL!!! Ain’t NO WAY that hotel lobby is “Good Air Quality” - the chemical smell is so overwhelming that I do not know how the front desk staff can sit there for 8 hours at a time… it cannot be good for their health. 11) I do wish to interview experts on the YT channel in the future. Mold experts, maybe health inspectors, etc. as it would teach everyone a lot - me included. But, IDK if I’ll be telling mold inspectors to visit certain businesses… not sure, yet. 12) So, we’ll see what the mold test kit results show. I don’t want to call out the hotel by name as I don’t wish to hurt their business but I do think their employees are in a very bad air quality environment so I’m not sure what to do on this… if the tests come back really bad. Maybe I’ll just make a video for “General Hotel Air quality Safety issues” and “start the conversation” as I am almost positive this type of unhealthy air quality environment is running rampant in the US hotel industry. I have spoken to many apartment tenants where it is also happening and therefore, it must be occurring in hotels, as well. The air quality in 3 of the last 5 hotels I stayed in seemed pretty unhealthy. When you own a home - you will see pipes eventually leak - even on new homes with good construction. Many homeowners don’t realize they have mold problems for years. Just imagine a hotel has thousands of feet/meters of water pipes that will eventually have some leaking… but when will staff detect the leaking? And what will they do to fix the mold resulting from the leaks? I also know a guy who stayed at a nice, expensive hotel a few years ago and he woke up in the middle of the night with 2 inches of water (5 cm) flooding his room. The pipes in the room above his broke and the water cascaded down room to room. Did the hotel bring in a high level water remediation company to prevent mold growth? - which would have cost tens of thousands? Probably not. Eventually, I think the US will pass legislation to make the air quality in hotels, schools and businesses much safer but that day is not here, yet, IMO. Thanks 4 reading - I didn’t intend to write so much but I can obviously be very Long-winded”, LOL! - the more I think things through. Stay Healthy!👍@@willyd2404

Hey Nathan - thank you for your feedback. Let me try to answer some of your points. 1) "Show me the performance numbers!" 1A) I think it is very difficult to accurately measure the performance of air purifiers for particles and VOCs and it requires expensive equipment, a controlled environment and trained staff - whom I would consider to be somewhat "experts" at testing. 1B) Yes, there are certifications in the industry like EN 1822 but I think some manufacturers are not always being truthful with the actual performance of their units in these tests... and the units oftentimes perform differently in the real world for customers (especially over time after some use). And/or different testing labs may be testing units differently than others. I will be learning more about this over time but getting accurate, 100%, black and white comparison data and test results between units is not easy to obtain. And I think many manufacturers are taking great liberties with their marketing and advertising campaigns. In short - there is A LOT of false advertising and marketing going on these days. 1C) Yes, I can use my 5 air quality testers to test some of my air purifiers but I do not trust their accuracy and none of them can test for the Ultrafine particles - which are the most dangerous to people. I've had air quality monitors tell me unit A was better than unit B on Tuesday and then on Wednesday tell me Unit B is better than Unit A. The EPA says testing monitors less than $5K tend to be inaccurate and more so over time. When I started the channel I planned on testing the units with monitors until I started working with them and researching their accuracy levels and I realized - I don't trust them. So, I currently believe testing needs to be left to the experts at this time. 2) "The filtration of the oil is only one factor in the breakdown of the lubrication and protection of an oil, so why not discuss that or even mention it?" 2A) People are watching this video for air purification content (not oil purification) and I just wanted them to realize that manufacturers ship defective filters all the time - regardless of industry - even simple filters. I don't think the vast majority of viewers would want to learn more about the oil purification process in this video. 3) "Focus on the value a product actually provides to a customer, not what the product can do overall. " 3A) The IQAir HealthPro Plus provides elite filtration - 99.5% down to .003 microns and ultrafine particles - which are the most plentiful and dangerous to humans. That is what sets the HPP apart from the vast majority of units on the market. 3B) This video was not a sales video for the HPP but rather to provide an example of the outrageous lies and deceptions that manufacturers fill the industry with. The Founder of Smart Air claims he "figured out' the air purification industry one afternoon all by himself and his cheap fan and filter are just as good as the elite HPP. The claims are mind numbingly ridiculous, IMO. And more importantly, Dangerous! 4) "HVAC side in terms of CFM and ease of use, but tell me why I’m wrong!" 4A) This would be the topic for a different video... "Air purification" is an endless general topic - with many niches and sub topics. All the info. cannot fit in one somewhat short video. 5) " If you aren’t able to confidently read the study yourself and analyze the efficacy, you shouldn’t spread the results as fact or even “possible links”. " 5A) There are many studies on the hazards of ultrafine particles and I've read some of them. I discuss this issue in further detail in some other videos. One single video cannot contain all the information and angles associated with air purification and the hazards of ultrafine particles. Again, this video is focused on the outrageous claims that some air purifier manufacturers are making. That is the entire point of the video. The industry is not regulated closely so manufacturers can typically say anything they want. 6) "The space would be better served by that than claims without basis or shaky stilts to stand on. " 6A) This video obviously contains my opinions. If some people believe that a $50 fan and filter perform just as well as a $900 IQAir HPP then they are welcome to do so. If some people believe that the Smart Air founder truly "Figured out" the entire air purification industry all by himself in just one afternoon... then, by all means - that is OK. And if some people trust the founder, who stated that all we need is a simple $50 air purifier (without carbon) - but then he turns around later and tries to sell a $1,000 air purifier to consumers (with optional carbon) and they still trust him. That is also OK. I currently disagree with some of his points and I made a video about it. I am offering my opinion but folks do not have to agree with me. 7) There are an endless number of topics to learn about in the air purification industry. I do not pretend to know it all as that would be absurd. I am a "student" of the industry and I learn new things all the time. I feel like I am still in the "early stages" of learning in many of the different sub topics - there is an ocean of information and things are dynamic, as well (new info. occurs all the time). I currently believe there are very few "experts" in the industry and they would only be in certain sub topics/niches (fan engineering expert, formaldehyde/mold testing expert, etc.)... but there is no such thing as an "expert" of the entire industry. I started the channel because I saw how much misinformation was being spread on YT and it really irritated me. My content is also changing over time as I learn more... we will see where this all eventually leads.... as IDK... Thank you for your feedback and Enjoy the Holidays! 😃

Thank you for your questions. If this is the video you are referring to: “Is an $800 purifier best to clean your home's air? We lab tested 5 top brands” kzfaq.info/get/bejne/ZtuKfqWd3LKpdqc.html&ab_channel=CBCNews Then, here are a few answers and points for you to consider: *1A) They decided to test “popular air purifiers” Dyson, Honeywell, Blueair, Germ Guardian, Levoit. NONE of these units are elite. The Blueair and Levoit don’t even have True HEPA filters in them. None of these air purifiers are considered “Very Good” or “Elite” in the world of air purification for particles. *1B) Jeffrey Siegel - the gentleman with the glasses is a Professor at the University of Toronto - and here is his background: Healthy and sustainable buildings, Ventilation and indoor air quality in residential and commercial buildings, Control of indoor particulate matter, Secondary impacts of control technologies and strategies, Aerosol dynamics in indoor environments and HVAC systems. Notice it does NOT say he is an expert at testing stand-alone air purifiers. He has a “general” background in indoor air quality but he is NOT an EXPERT at testing air purifiers… and he is NOT an expert at air purifiers, in general, either. If he was - he would have presented a much better list of air purifiers for this test. *2) None of these air purifiers have EN1822 certifications like the IQAir HealthPro Plus or the Aeris 3 in1. The EN1822 certification will test for Ultrafine particle filtration. UF particles consist of 90% of the particles in the air we breathe and they are by far the most dangerous to our health. *3) Please view this video for a better understanding of the dangers of UF particles - it is MINDBLOWING that not one of the so called “Experts” in this “testing video” mentioned UF particles. How could these “Experts” somehow not be aware of UF particles? LOL!: kzfaq.info/get/bejne/fc2ofs9i15y9g5c.html&ab_channel=AirPurificationEducation *4) At 3:06, the video says the people doing the testing are “PHD STUDENTS” NOT Air purification testing EXPERTS. They are NOVICES/Beginners at testing air purifiers - NOT experts. And NO they do NOT have the same modern, super expensive testing equipment that high-level, 3rd party testing companies possess. Not even close. If they did - then they would be able to provide Ultrafine particle readings down to .003 microns but they cannot. Or they would be talking about the MPPS of the filters on the units - the Most Penetrating Particle Size…but they don’t. They somehow don’t even mention UF particles which I find to be kinda crazy. 4B) Ami Li is the female tester in the video and here are the areas of her focus: Indoor air quality, HVAC systems, Smart ventilation and filtration, Air cleaning strategies, Indoor pollutant monitoring, Filter forensics, IAQ in community spaces, Impact of occupant behaviour on IAQ, Sustainable buildings Notice, NOWHERE does it say “stand alone air purifier units”. Nor does it say she has extensive experience as a stand-alone air purifier tester. She has “general, broad” Air Quality experience but not a specific focus on stand-alone air purifiers nor the testing of them. *4C) Bowen Du is the male tester in the video and here is what his description says: “I have extensive experience in experimentally investigating indoor air quality (IAQ) and its impact on health and cognitive performance. Recently, I am working on developing data-driven tools for assessing and improving building performance.” Again, notice he also does NOT have extensive experience nor expertise on stand-alone air purifiers nor the testing of such machines. So the two proclaimed “Expert Testers” they are using for the testing are NOT experts at testing stand-alone air purifiers. They are general “Indoor Air Quality” STUDENTS. BIG difference vs. a 3rd party testing company with experts who have years or even decades of experience testing air purifiers and who do it for a living. *5) At 10:24, She says the Blueair is twice as good as the others. Excerpt from Oransi blog (an air purifier manufacturer): "The CADR is measured with the air purifier run on the highest fan speed. If you will not be running the air purifier on a lower fan speed then the CADR that you will realize will be lower. The CADR is tested with a new, clean filter so it does not reflect the performance of the air purifier over time. A small, thin filter may test well in the CADR test but soon after show a large drop in performance. To better understand this our suggestion is to find out how much filter media is in the filters. In addition, the size of the air filters will factor into the expected performance over time. A large filter with a lot of filter media will perform much better than a smaller, thinner filter. You may want to watch out if the manufacturer does not provide this information." *6) At 13:00, they compare the units but don’t talk about how ALL the units have different CFMs on high speed. And the CADR testing methodologies only test brand-new filters at the unit’s highest speeds. *7A.) At 16:46, The Black Particle counter/sensor they are using is a Dylos DC1700 and the lowest a Dylos tester/sensor can read is particles down to .5 microns - which is NOT even HEPA level and consists of much larger particles than the UF ones. You said they used, “ super expensive measuring machines” but the Dylos DC1700 is only about $280 and I even have one. That is considered inexpensive for an air quality sensor. Even Marketplace said they used, “low-cost particle counters (Dylos DC1700)" in their blog post. Serious 3rd party testing facilities will have testing equipment, chambers, and software that costs tens of thousands of dollars and up. *7B.) And the host only mentioned the numbers for PM2.5 on the other tester/sensor sitting on the table. So, they are NOT testing for any of the Ultrafine Particles that comprise 90% of the particulates in the air we breathe. And they also happen to be the most dangerous to our health. They are really only testing for about 4% of the larger, less dangerous particles in the air. Does this seem like legit test to you when they are only testing the least harmful 4% of the particles in the air? Don’t you think the viewers/consumers should know this FACT? (CONTINUED ON NEXT REPLY)

*8) At 19:23, The Box fan DIY with MERV filter is a JOKE! And I almost cannot believe these “experts” decided to use one in the comparison. It truly shows their lack of knowledge and experience when it comes to air purifier filtration. They don’t even tell us what MERV filter rating they are using, LOL! That would probably be some useful information, right? Well, I researched it and it appears they used a MERV 11 filter. How does a MERV 11 filter compare to a HEPA filter? All HEPA filters are MERV 17 or above. There is a MASSIVE difference in performance. “A MERV 11 filter is capable of filtering at the following rates: 0.30-1.0 size microns greater than or equal to 20% 1.0-3.0 size microns greater than or equal to 65% 3.0-10.0 size microns greater than or equal to 85%” And they compare it to a Levoit air purifier which is designed for smaller rooms so it has less CFMs - so the Box fan may have somewhat of an advantage due to it’s stronger CFMs for the CADR results. But the Levoit may very well produce cleaner air in smaller spaces than the DIY Fan and MERV filter combination. No one with significant air purifier experience would seriously compare a MERV 11 filter that goes into your HVAC system to a good Air purifier with a good seal and at least a TRUE HEPA filter. They are miles apart in performance. But a MERV 11 filter may be “competitive” in this lineup of fairly weak air purifiers when only testing down to .5 microns in a smallish chamber with the fan set on high. The DIY Fan has some advantages in this particular test. *9) The Dyson fan air purifier is expensive but it is NOT considered a top-of-the-line air purifier. It is a fan and heater with “some” air purification capabilities - but definitely NOT a high level or elite air purifier for particulate filtering. I never recommended this Dyson fan/purifier to any of my customers over the 15 years of my air purifier consulting. And we were able to sell this product for many years. I never considered it to be a serious air purifier. *10A) At 19:56, The host says, DIY “produces more clean air than the Dyson”. Well, no one with significant air purifier industry experience would even use the Dyson fan in an air purification test… esp. for a covid issue. As they all would know it is not a strong air purifier. Plus, in their blog post about this video, they explain they only tested the units for particulates that are .5 microns in size and larger - which I thinks is absolutely RIDICULUOUS when this video also mentions covid: “Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus.” And viruses are .005 to .3 microns in size - ALL below the .5 microns they tested the units for. It just doesn’t make any sense to me to even mention covid if they only tested at particle levels that were larger than the size of viruses. .5 microns is not even HEPA which is 99.97% at .3 microns! Yes, the Box fan can look like a decent option in comparison to these 5 air purifiers as they are NOT elite solutions and the Box fan/Merv filter combo will move the air around the chamber faster than some of the other air purifiers… and it doesn’t posses any carbon to slow the CFMs down like the air purifiers it is competing against… so it will have an ADVANTAGE against some of these air purifiers in this particular test because they are only testing down to .5 microns and all the other units have carbon components slowing down their CFMs. *10B) Even GermGuardian wrote to them and said, “We do find it interesting that you are comparing complete air purification systems to “Homemade box fan filters” which would be expected to have relatively high CADR’s.” “While a box fan + MERV 11 filter may deliver a relatively high CADR as a temporary solution, it doesn’t take into account the design, footprint, noise level, durability or overall performance of the entire air cleaning system which includes our combination of HEPA + Carbon Material Filters…” The DIY Fan solution doesn’t posses any carbon so it won’t help with odors or VOCs. Carbon will slow down the airflow and CFMs of an air purifier and therefore hinder it’s CADR performance. The DIY Fan solution had a distinct advantage over the other units on the carbon issue as the test did not check for VOC absorption. That in itself, should take the DIY fan solution out of the testing group as it arrives with an unfair advantage for this particular test. *10C) And Dyson provided this statement: “The CADR metric is the rate a purifier cleans the air (i.e., speed). A high CADR score alone does not make a good air purifier. You need to have a machine that is HEPA-level filtration, pollutant sensing, and strong air projection. CADR does not measure these things." That DIY fan/merv filter combo will NOT come close to looking good in a similar test against better air purifiers like the IQAir HPP if they tested to even .1 microns as the HPP is rated at 99.5% down to .003 microns. *10D) And the Dyson engineer they interviewed literally said, “We are not engineering our products to specifically have an enormous CADR because we believe that that’s just one metric.” He is correct about this. *11A) At 20:31, The host says “our experts say it’s the most important metric.” They are saying that CADR is the most important metric. Well, they are DEAD wrong on this issue and therefore cannot be true air purifier “experts”. We already know they aren’t air purifier experts because they brought in 5 very average air purifiers to test in the first place. They obviously don’t know the air purifier industry well enough to recommend 5 good units for an “Air purification comparison show that mentions Covid”. Not having the IQAir HealthPro Plus in the lineup was like leaving Porsche and Ferrari out of a “Best Sports Car” test. Their “experts/scientists” may focus on “Indoor Air Quality” but that deals with many different sub niches and air purifiers are just one of them. Their “experts” clearly do not have extensive experience with reputable air purifiers. Please see my video on CADR Ratings and why they are NOT reliable: kzfaq.info/get/bejne/g5uXe5l6p9e0m5c.html *11B) Dyson talks about the limitations of the CADR ratings and have a suggestion for more accurate testing: www.dyson.com/discover/innovation/behind-the-invention/what-is-cadr Other companies like IQAir and Austin Air (and others) agree the CADR is NOT a good test for comparing Air Purifiers. *12) At 21:45, again, they stress the CADR. They say, “If you are shopping for an air purifier check for the CADR”. Again, this is NOT the most important variable to check for, at all. If anything - check to see if the unit is EN1822 certified and THAT could possibly be a good starting point if you want a solution with high-level particulate filtration. These are my current feelings on that particular video and test. I reserve the right to change some of my opinions if provided with additional information. I hope this answers some of your questions. Thanks!👍

1) Yes, I know I repeat too much - I try not to but IDK - may be my thinking process, I may have ADHD, I am not sure but I know I repeat too much for some reason. 2) I started the channel by thinking I was going to "test" many different air purifiers with sensors and show the results. But I now have 5 air quality testers and unfortunately, after playing with them for a while and doing more research - I came to the unfortunate realization I would be misinforming people... and lying to myself if I didn't state the truth... they can't be trusted. This set my content schedule back many months as I had to find other ways to evaluate the solutions. 3) Then I figured - some units are 3rd party tested so I can just gather those results and that would help rank the units. Right? I mean, the 3rd party testing labs are going to be honest and provide reliable testing data results. Right? But now, after looking into it... I realize some of the manufacturers are lying about their 3rd party testing results - as crazy as it sounds, and they can't be totally trusted either. When there are millions of dollars on the line - some folks will go to great lengths "stretching the truth" to sell their units. The industry is filled with lies and deception - even more than I had realized. 4) So, I can only do my best and analyze things to the best of my abilities and learn new things every week... this is where the journey has taken me. 5) Also, I tried to purchase the $45 Smart Air DIY Fan/Filter to evaluate it... and I was actually OK with paying over $100 for the shipping but... they still would NOT ship it so I don't think it is available in the US for whatever reason. Thank you for the comment/feedback and enjoy the Holidays! 👍

@@AirPurificationEducation@AirPurificationEducation I came to KZfaq for tips, insight, and budget-friendly solutions for cleaning the air in my environment. I can't enjoy "normal" breathing life for 7 out of 12 months of the year. Filtering through the BS is exhausting. But reading your humble, honest, authentic comment to this response left me feeling joy. No one has the answers; we are all just winging it. I appreciate your time, effort, and transparency. Maybe I'm naive; perhaps I'm not. Keep up the hard work. Stay kind. Stay classy. ;)

Thank you for your nice comments but I cannot promise I will remain "kind" and "classy" in the future, LOL! As I think I may start becoming a little more aggressive in my approach.

​@@AirPurificationEducationthanks for further details and makes sense. Enjoy your holidays as well

Look up the info from NASA, they tested the HEPA filters and published a study. (link edited to pass the comment filter) "How do HEPA filters work? It is widely believed that HEPA filters are only capable of capturing particles sized 0.3 μm or larger. However, this belief is based in part on an incorrect understanding of how HEPA filters work. The fact is that particles of around 0.3 μm are the hardest to catch (Perry J.L., Agui J.H., Vijayakumar R. Submicron and Nanoparticulate Matter Removal by HEPA‑Rated Media Filters and Packed Beds of Granular Materials. NASA/TM‑2016‑218224 ntrs nasa gov archive nasa casi ntrs nasa gov 20170005166 pdf1​); for this reason, that size is used to measure the effectiveness of HEPA filters. Much smaller nanoparticles are in fact easier to catch. But why is this so? For larger particles, the HEPA filter acts like a net as we would expect. Particles greater than 0.3 μm in size simply cannot get through: either they do not fit through the holes or they hit the filter fibers due to inertia. For smaller particles, on the other hand, it would seem logical that they can simply go through the holes. However, this is not the case. The tiny mass of particles less than 0.3 μm means they do not fly straight; instead, they are bounced off other molecules as they collide with them and thus move in completely random patterns. As a result, they hit the filter fibers and then remain stuck in them. This is the principle of Brownian movement." - Hamilton Medical
