Thanks 4 the comment!👍

Thank you for your kind words. For substantial cooking odors I'd go with an IQAir GC unit and I'd contact Airpura.com and ask them what they think is best for your specific environment as I consider them to be kinda like carbon experts. Happy New Years!😃

Thank you for your comment! 👍

Hey, thank you so much for your feedback. I appreciate it. 👍 I consider myself a "student" in this air purification world. 1) I think I would really try to figure out what the odor is that you are smelling in your environment, if possible. That kinda makes me pause and I think it would really help to know what it is, exactly - if possible. If you need a hardcore carbon solution for a serious odor/VOC issue then I think you may also wish to look at the Airpura.com product line as they specialize in different carbon blends and I consider them to be experts on the issue. And depending on what the VOC/odor is - they could tell you the best carbon combination for the job. + I think the particle filtration in their units is good and they offer "Super HEPA" options, as well - which may possibly approach the IQAir HPP and Aeris 3 in 1 units for particle filtration but I'm not 100% sure, yet. Either way, I really trust them and they've made some of my customers really happy in the past. Maybe they could provide some tips for you to figure out exactly what the odor is... 2) That said, the GC is very good for odors but replacing those filters can get pretty expensive and it doesn't filter the most dangerous ultrafine particles as well as the IQAir HealthPro Plus. I've become somewhat of an alarmist on the whole Ultrafine particles issue over the past several months as more and more research is linking them to cancer, Alzheimer's, heart conditions, etc. - because they can get directly into our bloodstream... Because of this - I currently prefer people go with the 2 best ultrafine particle air purifiers I know of, if possible... The IQAir HealthPro Plus and the Aeris 3 in 1. They both have a decent amount of carbon and I'm running the HPP in my family room (seems to be good for odors) and I will soon be replacing the Austin in my bedroom with the Aeris 3 in 1 - due to the Ultrafine particle issue, as well. It is possible either unit has enough carbon for your VOC/odor needs in the 500 sq. ft. - the main difference IMO, is- that the HPP has more carbon and you can replace the HPP carbon filter for about $99 when it gets saturated but the Aeris unit will cost $200 to replace the carbon as it is combined with the other 2 filters in the cube... so if you need significant VOC/odor help - the Aeris could become quite expensive if you have to replace the carbon over and over... So, I think I may try the HPP in the 500 sq. ft. odor area.... Those would be my initial thoughts. Please let me know if you have any questions. Thank you and Good Luck! 😄

I currently have ambivalent feelings about the Austin Air Healthmate: 1) It was the 1st air purifier I ever purchased and it did a great job for me as I bought it because I was gagging on dust (I think it was coming from my ducting when our heat turned on) when I was trying to sleep at night and I was waking up at @ 2-3 am coughing, etc. I'd have to drink some water to try to get back to sleep again but I'd be up for about 30-40 minutes b4 I could get back to sleep and this really irritated me. The Healthmate fixed my issue the 1st night in my room and I was very grateful + I never had that problem again for 16+ years with it running 247. My experience with it + numerous interactions with customers over 15 years tells me it has definitely helped a lot of people with many different breathing issues... for sure. So it is a quality unit, IMO. 2) That said, I saw it tested in Vegas with a $3,000 particle counter by the Owner of IQAir vs. the IQAir HPP and a Blueair unit. The HPP registered a perfect score with the monitor. The Healthmate was tested next and it performed at 98% efficiency on low speed, 96% on Medium speed and 92% on High speed. But I could tell the owner of IQAir respected the unit and felt it was a good offering. Then the Blueair unit was tested and it hit about 82% on whatever speed but it was not nearly as impressive as the HPP or the Austin. The live test made an impression on me for many years. Then over the past year I started to use various testing monitors (much less expensive... more like $300 to $150) and have come to the conclusion they are NOT reliably accurate. And the EPA says any testing monitor less than $5K tends to be somewhat inaccurate. I've talked to Austin and they say the electronics of the HPP interfere with the testing monitors and therefore provide false readings. I've seen that when you put a testing monitor close to fans without any filters - the readings can register as perfect air quality, as well. Basically false readings... So, now I question if the IQAir live test I saw was somehow "rigged". Did he put the monitor closer to the mouth of the HPP unit during the test to get a false perfect reading? I don't remember. But I will say, I don't believe he is the type of man to do such an underhanded thing. He seemed to be an honest man... but who knows, right? He wanted all of the dealers to sell his units and grow his brand in the US at the time so he definitely had a "motive" so to speak. I still don't know... All that said, I've had many fantastic testimonials and some great feedback with HPP customers through the years and I know regardless of what any testing monitor's numbers can show me that it is an elite-performing air purifier for particle filtration... no question in my mind. 3) Years ago I had a rep. from Blueair and a rep. from Austin tell me that they both knew the HPP filtered better than their units. So, why would I not believe them - right? 4) I think most air purifiers on the market do not actually work at a HEPA level but they don't need to in order to help people with their breathing... most all air purifiers will improve the air quality in a room to some degree... but obviously, there is a pecking order regarding performance (esp. with Ultrafine particles) and I currently think the HPP and Aeris 3 in 1 are 2 of the best. 5) I recently asked Austin for 3rd party data/reports that proved their units worked at a HEPA level but to my shock - they didn't really have any. I could NOT believe it. They say they are "3rd Party" tested but they only have some "clinical trial" type experiments/data/trials with some reputable health organizations... but the data I read from these trials did not impress me as I didn't see any black and white super convincing results. Now, maybe I didn't read all of them and maybe I am missing something but if I was in charge of a reputable air purification manufacturer and I was proud of my product's performance - I'd have some SEVERE 3rd party testing data that was very black and white and I'd be beating the competition over the head with it - yelling from the rooftops with it, so to speak. IQAir has EN1822 testing results that appear to be black and white and EN1822 is one of the most respected "certifications" in the market today - from what I currently gather. Now, was the entire unit certified or only the filters? IDK but I'll eventually find out... either way, they have a 3rd party certification that I think is impressive. I do not think Austin currently has this... 6) I do not have much experience with the Atem X, at all. That said, based on limited research - I think the HPP filters Ultrafine Particles better than the new Atem X. I think IQAir was somewhat forced to come out with a better-looking unit with "smart" features to keep up with the competition however, I do NOT believe it filters HEPA sized particles or ultrafine particles as well as the HPP. And I also think IQAir tries to kind of "hide" this fact based on what I am reading in their marketing materials. I do not think the X's filters are EN1822 certified and I see IQAir pushing impressive Virus Removal data performance numbers on the unit on their website. However, I don't see anywhere that it actually performs at a HEPA level. A) The HPP performance numbers say "Filters 99.5% particles ≥ 0.003 microns" right on their website... but I only see a UK IQAir dealer called Allergy Cosmos say, "HyperHEPA Filtration: Similar to the HealthPro 250 (which is the international number for the HPP), the Atem X utilizes advanced HyperHEPA filtration, EN1822 classified at E11 to H13 (notice they say "Similar", "utilizes" and "classified" but never actually say the filters themselves are EN1822 certified/tested). B) "The Atem X captures ultra-fine particles at 0.3 microns with an efficiency of over 95% on the highest setting and 99.95% on settings 1 and 2." BOOM SHAKA LAKA! Right There... THAT is all we need to know, I think. Actually, IMO, they tried to be a little sneaky with this sentence as "Ultrafine particles" are defined as .1 to .003 in size... and .3 microns are considered "Fine Particles" and those definitions are literally coming right off the IQAir chart. But they used the "Ultrafine" term in combination with ".3 microns" in the same sentence. IMO, they did this to try to fool people and have them think the X performs as well as the HPP for Ultrafine particles. And I had to do some searching to finally find this info... I think IQAir wants to "hide" it from consumers. I think the HPP performs at 99.5% down to .003 microns even on the highest setting but the Atem X clearly filters particles at worse rates when the CFMs are increased. And according to their UK dealer - it NEVER actually hits 99.97% at .3 microns. But the HPP definitely does. C) So, the X is "Good Looking/Better Looking" than the HPP. Has additional sensors to test for different things in our air. Is more powerful so it covers more cubic footage. Is "smart" so to speak and has all the digital/phone features that folks could probably want... but, I personally, don't care about any of that stuff, lol! I want the superior filtration. So, this is what I currently think about the X based on what I'm seeing. Thank you! 👍

Yes, in general, I do not like washable filters. I read an asterisk next to a "washable prefilter" from a brand a few days ago and they mentioned that the filter did not perform as well after it was washed. And I kind of felt like I've always known this. I do not currently think it is reasonable to believe that a washable filter will perform as well as a brand-new filter. That said, I am more biased against washable HEPA/Main filters... if it is a washable Prefitler - they deal with the larger particles so I don't think it is as big of a deal but me personally at this point in time (until I see some differing data) do not think a washable main filter is necessarily a good thing. Air purification companies know that consumers LOVE the idea of washable filters so some of them will try to cater to them on this issue, but I think they will not work as well as new filters and sometimes the difference in performance may be large... Thanks! 👍

Thank you for your comments: 1) "zero air filters have a perfect seal, so it's just a minor side topic..." ***Yeah, I don't currently agree with this, at all. One of the things that makes the elite air purifiers perform better is the superior seal and lack of leaking - from a particle filtration standpoint. 2) "even a Merv 11 will do about the same as a IQ Air, and if you get a much bigger fan and multiple Merv 11, it will do better than an IQ Air.." *** I currently would have to disagree with this, as well. The MERV 11 won't come even close to the filtration of an IQAir HPP. 3) ".3 is the size that is hardest to filter," ***updated information/testing has shown that the MPPS will depend on the specific filter being tested. Different HEPA filters have different MPPS. 4) "at lower sizes it becomes easier to filter (including ultra fine particles) and at higher than .3 microns it becomes easier to filter" *** I currently believe this to be true only for very well manufactured HEPA filters... but I currently do not believe all HEPA filters will filter at the same levels and not all HEPA filters will filter the Ultrafine particles in the same manner. 5) " IQ Air's testing/certs don't really prove that it's better than any others..." ***I currently do not believe this to be true. 6) "One thing IQ Air is better at is that their machine is so quiet," ***I honestly don't think it is very quiet compared to some of the other air purifiers I have... I love the white noise that most air purifiers create... I'd say Blueair is probably one of the more quiet solutions - esp. in comparison to the IQAir HPP. But, I guess the IQAir HPP is pretty good/quiet from a sound standpoint up to speed 4... 7) "but it's not much better than a house fan with a Merv 11 on it and it's not any better than a common Honeywell machine..." ***LOL!!😆 I do respect everyone's opinion but I don't know how you are coming up with these comparisons. My professional experience in dealing with hundreds of IQAir customers has proven beyond a shadow of a doubt it is an elite filtering air purifier and no, a Honeywell air purifier doesn't filter nearly as well. I've sold both. 8) "VOCs can only be filtered to about 9% reduction by carbon, even the IQ Air or the huge Airpura carbon filters only remove about 9%." ***I don't know how you are coming up with these opinions - but this has not been my personal experience with air purifiers and definitely not the experience of thousands of customers and businesses I have dealt with from all over the country for over 16 years. 9) " Just some facts for you. The rest is a lot of hype and marketing catch-phrases for people who don't understand much about filtration. The main thing about filtration is the size of the filter and the volume of air the fan can move through the filter per unit time, only after that can you start to talk about filtration media which is more or less the same from a tshirt up to a ULPA and is just 10% of the equation." *** I do appreciate your "Facts" LOL! 😆 but I currently think you are way off with the vast majority of your opinions on these topics... and my professional experience with THOUSANDS of real world customers and some high level (even brilliant) engineering experts from some of the best schools in the world (including MIT) do not agree with many of your opinions. But we are all allowed to have our own opinions. 10) " The main thing about filtration is the size of the filter and the volume of air the fan can move through the filter per unit time, only after that can you start to talk about filtration media which is more or less the same from a tshirt up to a ULPA and is just 10% of the equation. " *** I disagree 11) " Also using carbon will actually clog the HEPA filter and carbon only works for a short amount of time and you never know when that is because it depends on the amount of toxin in the air, the temperature, pressure, etc." ***I do agree with you that carbon can clog a HEPA filter. And I know there are many different types and qualities of carbon out there. And I agree that some of the carbon will not last a long time, for sure... And I will be learning more about this over time. Thanks a lot for your post. We don't currently seem to agree on much, LOL! 😆But that is OK! If everyone completely agreed on everything I think there would probably not be a lot of progress made in the world. All that said - as always - I don't necessarily want to be "Right" - I want to find the "Truth" so, I reserve the right to change my opinions on these topics over time as I learn more about the different issues, etc. Thank you for your post!👍

I should be getting an ATMO - personalized air quality monitor today to play around with. It uses AI to to try to figure out the AQI. IDK how accurate it is... but, I am optimistic that in the not too distant future some company will eventually make some very reliable air quality testers at affordable pricing. I think the market is screaming for this and there are so many talented and smart engineers around the world that I feel air purification solutions and monitors will become more advanced and better over the next 10 years as poor air quality is becoming more known as a serious threat to our health. More and more money will be investing into this industry and better solutions should begin to appear over time... Some may already be here - I just don't know what is going on all over the world currently - in this regard, lol! 😄 Thanks!

Thank you for your question. If you want a decent air purifier for dust/particles I currently think the Coway Mighty is the best unit for less than $250: amzn.to/49QBdpm I currently would rank the Winix 5500 - the 2nd best unit for dust less than $250: amzn.to/447zfP0 Hope that helps - thanks! 👍

@AirPurificationEducation thank you I appreciate that!

You are welcome - Good Luck!👍@@SALOALBERTO

@AirPurificationEducation I've read in the comments, both of these units have a seal problem on the HEPA filters, Is there any units with better build quality that perform better even if they are in the higher price rage? I was recommended by a co worker to try Mila or Oransi. Have you tried either? Thank you very much.

I've seen your suggestions on the IQ and the Austin etc but I'm not sure if they are to big for a bedroom.

I want to learn more about the HEPA filters in the future but yeah, most people simply think "HEPA Filter" means they are all EXACTLY the same.... a $29 HEPA filter and a $100 HEPA filter. I just want people to realize that is NOT the case - there must be many different levels to "HEPA" quality, IMO. Unfortunately, I think I have to leave the testing to the 3rd party labs... testing of air purifiers and filters is kinda tricky, I think. I was planning on doing testing on this channel... - until I realized that it should probably be left to the experts with the correct modern equipment and training, Ie. 3rd party labs. Thanks!👍

Thank you for your question - can you please tell me... 1) What is the size of the room you are putting it in? Square footage and ceiling height. 2) What do you want to filter out of your air the most? What is the 2nd most important thing you want to filter out of the air? Thanks!

Thanks for the comment. I am not familiar with the Xiaomi mi air purifier 4 but I just looked at a video on it and it does not have a gasket connecting the filter to the inside of the air purifier. The seal is plastic on plastic which is not a good seal. You need a good gasket and a strong seal between the gasket and the inside of air purifiers to prevent air from leaking around the filter. So, based on that alone I'm very confident it does not filter at 99.97% elimination of 0.3μm particles. Plus, it has the carbon come last in the filtration process and the best air purifier companies always put the carbon before the HEPA filter or you can get carbon in the air you breathe. I will definitely be doing a video in the future on the importance of the gaskets and the seals inside air purifiers in how they help or hurt the overall performance of the air purifiers. In the US, we have something called the CADR ratings to supposedly compare the performance of air purifiers against each other but the CADR testing procedures have many problems with them. So they should not be used to try to figure out which air purifiers are the best. I made a video on this called "Is the CADR Rating Important? NOPE! It's GARBAGE!": kzfaq.info/get/bejne/g5uXe5l6p9e0m5c.html In general, air purification companies have a lot of leeway to say whatever they want about their products and few will challenge them. I consider Air Purification marketing to be the Wild Wild West these days. Many companies shamelessly make ridiculous claims about their products that the general consumers will not be able to verify. Another problem is the vast majority of air purifiers are tested when the filters are brand new and clean. But this is not what the consumers deal with in their real world environments. The air purifiers will typically perform much differently after 2-3 months of use when the filters get dirty. There will be less CFMs and usually much more dirty air coming out of them. So, to really test them correctly for particulate filtration - a company would have to test them after 3 months of use and somehow make sure all the air purifiers were subjected to the same amount of pollutants over the 3 months in different test chambers. As we can imagine - it would probably become expensive and difficult to pull this off perfectly. Thank you!👍

Thank you for your question. Do you mean - what are some good air purifiers? Thanks!

I own 5 different Air Quality Monitors if that's what you mean. I don't think they are super accurate. If you didn't see this video - the Dylos DC1100 Pro and Temtop disagreed with each other on the quality of the air about 84% of the time in this hotel room: kzfaq.info/get/bejne/iNN5gJyXu9e2fo0.html I currently think the only "testing" that should be done on air purifiers to truly compare them to each other - should be done by professional 3rd party labs. If that is what you are asking. Thanks!👍

Ahhhh Marcus... my FAVORITE Poster is back! 😆 1) I think they may be defining "efficiency" as lower CFMs... and not just the particle filtering capability of the unit. Like the units CFMs can go down 50% after 2 months of use as the filters get more clogged. Which I do think is very possible in a dusty environment. I felt a severe drop in the IQAir HealtPro Plus' CFMs over time - that I sat next to at work because it was about a foot away from me and blowing on my arm. So, I just started using new filters in the HealthPro Plus in my family room and I tested the CFMs from 6 feet away on high speed and we'll see how it performs every 3 months as the filters get clogged. 2) I am happy to hear the new Winix 5500s have better seals as it was a huge hole in their older offering, IMO. I will be buying a new one soon to check it out. 3) "You could test these Purifiers exhaust with a particle counter" Good suggestion and I would have agreed with you on this about 9 months ago or so but I've lost all confidence in the accuracy of particle counters since then - so I don't want to provide folks with "inaccurate" "official data" which I think some other KZfaq sites are currently doing (without realizing the devices are not super accurate). Your suggestion was one of my original plans when I started this channel but the more I experimented with the sensors and learned more about them the less confidence I had in their accuracy. Testing must be left to the experts, IMO. 4) " I still believe that Winix and some other brands do a better job at filtering the air than you are suggesting in this video and are very good value for money but im open to be proven wrong" A) Here is the deal - MOST all air purifiers will improve the quality of our air- even inexpensive ones, IMO. And even a Box fan with Merv filters. However, the high level solutions like IQAir and Aeris will be more beneficial at removing Ultrafine particles so they are better for our long term health. And the Winix 5500 IS a GREAT value for the money for the level of filtration it provides customers. But the theme of this particular video was to provide "13 reasons why I believe over 90% of the HEPA air purifiers don't actually perform at a HEPA level." Because... they don't... especially after the filters get dirty and you run them on higher speeds... THAT was the point of this video I wanted to hammer home. SOOO many air purifier companies use BS marketing techniques claiming to perform at a HEPA level and I want people to realize that MOST do NOT. It is NOT easy to engineer an air purifier that works at a HEPA level after 3 months of real-world use. Sorry for all the capital letters - I've had too much Vietnamese coffee - I'm not yelling at you... just yelling into the Internet, LOL! 😆 B) I think that most air purifiers do not filter at a HEPA level but they do NOT have to in order to improve someone's air quality. All they have to do is "Approach HEPA" IMO to help many people... and "Approach HEPA" is a very gray term... I know, LOL. I came to that conclusion years ago after years of talking to many different customers. I wanted to end the video by stating this but this thing took me forever to make and there were about 5 things I wanted to change/add and I eventually just said, "time to upload" as I could have worked on it for another 2 weeks... All that said, some people really do NEED a super strong HEPA solution to help relieve their breathing issues... Some folks need the best air purification solution for relief. And I think, most everyone would benefit more if they all had the best air purification solutions - However, it is an issue of $$$ (and understanding). I know. 5) "The Aeris looks like a very good unit although long term reliability is yet to be proven." Agreed 100%. Thanks for your comments! 👍

​​​@@AirPurificationEducationYes I agree the older the filter gets the more resistance to the airflow will occur, having a washable or replaceable 😢pre filter and carbon filter will help to some extent. I also agree that severely allergic people may have to pay the higher prices to get relief. I recently purchased 2 Camfil City M air purifiers. These purifiers are the benchmark in my opinion but of course they are not really built for the domestic market so not a fair comparison. The quality of manufacturing is top class though and each filter is tested and stamped to have an efficiency of 99.995% at MPPS the filters are very well built with a metal frame and grill to protect the media and very well sealed. 😊 And yes leave the testing to the reputable professionals problem is not many Brands use them 😂

I would Aeris to look at the set up of their filters. I would like to see either a seperate replaceable pre filter or a washable pre filter and a seperate carbon filter, they have a very large Hepa filter and i'm sure that would last a lot longer than one year if it was seperate to the other filters. It would mean a more complicated filter change but could be designed to be a lot easier than the IQ Air

Hey Marcus, I just looked the 2 Camfil City M air purifiers up online and they look impressive. I don't think I've ever seen an air purifier that pulls the air in from the sides and disperses the clean air at the bottom - very unique! Can you please tell me - why did you purchase them? - if you don't mind me asking. I am assuming they were a job-related purchase? Thanks! @@2711marcus

1) I just took the prefilter out of the HPP a day ago and I really DISLIKE trying to get it out from the unit - I wish they could find a better way to improve the process. I think older people must have a real problem accessing/replacing it. Because I've been dealing with the HPP for over 10 years and I still have problems with the Prefilter - even when I'm sober... so, I can imagine what other folks must think about it... LOL! 2) I think you are right about the Aeris filter but I will say I think one of the advantages of their filter set up is they really only have 1 seal to make perfect between the filter cube and the interior of the air purifier... and I currently think, the less seals you have to make perfect - the less chances/variables that can get in the way of your unit filtering optimally, IMO. I'm going to make a video on the seals within the units soon when I feel ready... I've been thinking - I don't think it is a coincidence that the HPP and the Aeris units have their filters set up in a similar manner in the units and the air is being blown through them similarly, as well - and they are 2 of the best particle filtering units on the market... I think Aeris kinda leverages gravity with their seal and the HPP's filters "lock" together like a puzzle so air can't escape the unit out the sides... I'm gonna think about it more and do a video eventually - thanks! @@2711marcus

These are some good questions - let me think... My current opinions would be: 1) Yes, I think if you did do something like tape the gaps between the HEPA filter and the inside of the air purifier - it is possible it could be an improvement. It seems like that would improve the leaking issue between the cardboard housing and the inside of the air purifier. I don't know if that is a good idea as the HEPA material is supposed to be somewhat fragile and it can have openings/leaks we cannot see - so I'd try to be careful if I tried to do this. 1B) The tape and glue on the tape could off-gas into the air, as well = more VOCs. Depending on the type of tape used. But on the surface - tape does seem like a decent idea. I'm not saying anyone should do this and I'm not sure how the manufacturer would feel about it. I will try to remember to ask someone with industry experience about this in the future. 1C) That said, the HEPA filter itself probably leaks some dirty air as well, (especially after some use) and probably doesn't work at a True HEPA level - especially on higher speeds. And air purifier companies oftentimes will have HEPA filters inside their units that are not really strong enough to work well on the higher CFM settings, either. The more the CFMs the more the leaking (this is well documented on even high-level, expensive, air purifiers with much more expensive and sophisticated HEPA filters.) So, if we tape the gaps between the HEPA filter and the inside of the air purifier - and the air is then really forced even more to go through the dirty/clogged HEPA filter (after 3 months use, etc.) then I think it would possibly be an improvement but I also think it could make some of the dirty air leak in other areas, as well - depending on how clogged the filter is and what CFMs the unit is run on... All in all - if I had to guess - it seems like taping it could be an overall improvement in air quality on lower CFMs. I will be getting the newer Winix 5500 soon to see if they have addressed this issue. 2) On the surface, this may seem like a reasonable idea. It may be somewhat true for larger particles (that are less dangerous to us) depending on the size of the room and the particles in the room. 2B) I think in the real world - contaminants and dirty air are constantly entering rooms on a regular basis + there are particles everywhere on the ground, ceilings, walls and counters, etc... and there really is no such thing as a true "Total Air Exchange" in a room in the real world. When we get up and walk across the room we stir up particulates everywhere. When we sit on our bed, we kick up a bunch of particles that had been lying on the covers, etc. There are even small air currents always occurring in our rooms all the time without us ever noticing. So, no air purifier ever totally cleans the air in a room. We call it an "Air Exchange" but it is really more of a "Partial Air Exchange", IMO. 2C) So, we want the cleanest air possible coming out of the unit, in general. The smaller particles are the most harmful to us (ultrafine .1 to .003). And since Ultrafine particles are the most dangerous to humans and have been linked to Cancer, Alzheimer's, Cardiovascular disease, etc. - we really want to eliminate those as best we can. Also, dirty air coming from air purifiers will get dirtier and dirtier as the filters age and get dirtier, as well. So, folks will be breathing in more and more dirty air with more and more ultrafine particles so - no, I don't think it is good at all for the most dangerous ultrafine particles. If that makes sense. 2D) Also, the carbon in air purifiers tend to work better on medium and lower speeds as it enables the carbon to absorb the chemicals/odors much better. Thank you! 👍

Thank you for the very detailed response. I really appreciate you and your channel. It seems that many others on the internet take manufacturers’s claims at face value. Have you heard of the IPS7100 particle sensor? The manufacturer claims that it can accurately detect particles from 10um down to 0.1 um. It’s also only $100. www.ncbi.nlm.nih.gov/pmc/articles/PMC10018765/ This paper reviewed it and two other similar devices. It found that the device was only accurate in measuring particles 0.1um to 1um and inaccurate for larger particles. But this is actually great news because it’s the smaller particles that are more dangerous and harder to filter. I’m thinking about buying this sensor but would love to hear your thoughts on it.

Just opened the new Winix 5500 and the issue has NOT been fixed - the HEPA filter still does not have a gasket and I can hear and feel the filters jiggle in the air purifier when I shake it. So, there is no way the 5500 is actually filtering at a HEPA level and I just opened the Coway Mighty and it has the same issue, as well.

thanks for your clarifications​@@AirPurificationEducation

I made some comments on some past videos and YT would delete them as well (but only in the past 3 weeks for some reason). VERY frustrating when you really put some time into a post.😠 So, I think I've learned to copy some of my longer comments (and let's be real, I tend to sometimes write a short novel on some of my comments), LOL!

The topic of this video was not specifically about an Austin being better than a Winix - the topic of this video is to show that not all HEPA filters are the same and they don't all filter at a HEPA level like so many consumers believe. In fact, over 99% of the so called "HEPA" air purifiers do not actually filter at a HEPA Level. Did you see the 2 black gaskets on the Austin Air Filter on the top and the bottom of it? Do you see any gasket(s) on the Winix Filter? No. The gaskets on the Austin filter will help create a decent seal between it and the inside of the unit. The lack of a gasket on the Winix filter means it is going to be prone to having dirty air escape around it - and we can easily see that is exactly what happens. So, although it was not the specific intention of this video - yes, I actually did demonstrate that the Austin Air seal is much better than the Winix seal and thereby the Austin air purifier will filter better than the Winix one. I was actually just trying to show that the original Austin Air filter from the manufacturer was superior in quality to the Chinese made Monster Filter version of the Austin replacement filter. I will be making a video in the future on the importance of the seals inside the air purifiers and I will compare the seals of about 10 different units so everyone will easily understand this super important component of air purifiers.

I can see your point and I believe I can address your concern. The Austin filter is big, heavy, and designed not to need replacing for 5 years. I’ve had an Austin HealthMate for 9 years and I have closely inspected the gaskets on the two filters that it has used during that time. I wanted to make sure that there wasn’t any air escaping the charcoal/zeolite filter and the HEPA filter given the cost of the unit and the replacement filters. The gaskets are a thick firm rubbery material that forms tight seals with the inside top and bottom of the unit. The fit is so tight that the gaskets show continuous and perfect indentations matching where they attach to the unit. Those seals are not coming loose unless you destroy the top or bottom of the steel case. (Doug could have flipped the unit over, taken off the bottom, and pulled out the filter to show this. Or he could have used a fiber optic scope.) The Winix filters are more like furnace filters that are designed for easy access and changing. I like my HealthMate but I have looked at a lot of other machines over the years because they have timers, remote controls, status lights, etc. The HealthMate just has a 4 position switch to control the fan speed. If I had had more funds I would have probably bought an IQ Air. Apologies if this sounds preachy.

IDK, man... I think I need to start paying you, LOL! 😆You are too good with your comments and suggestions... I'm gonna eventually make a somewhat comprehensive "Gasket/Seal" video in the future with about 8-10 different units or so, and I think it will really help a lot of people understand the importance of a good, tight seal inside the units. It is on the "ToDo" list - for sure! I think you can disregard my other comment about watching this video as it looks like you've already seen it - thanks!👍 @@JBass33

I'd say over 99% of the "HEPA" air purifiers don't actually work at a HEPA level in the real world but most all of them will improve the air quality in a space to varying degrees depending on how well they are sized and which unit is chosen. And therefore, many of the units will actually improve the consumer's overall health, in general. Even though, they are not hitting 99.97% at .3 microns - like so many of the manufacturer's advertise. So, the units typically do not actually perform to the level the consumers may think they do... And yes, some of the units are not good at all and in some cases - yes, I'd say the consumers are getting robbed by those companies... Now, on the Air Quality Testers/Sensors issue... yeah, I think many are providing somewhat inaccurate readings and when they say the air quality is "Good" in someone's space - that may not be the case, at all... so those consumers aren't even improving the air quality in their environment with that purchase - they are oftentimes being provided a "false sense of security" by the air quality testing sensor they purchased, IMO. Thanks!👍

@@AirPurificationEducationI’m not an expert in this field but I thought the same thing just based on common sense 🙂

Just based on “rookie common sense” why would something as basic looking as this hepa thing be able to filter something as tiny as particles and microbes that can barely/only be recognized under a microscope🤔 That’s kind of like putting a mask full of holes in front of your face imho

Someone deleted an opinion related to air quality and air purifiers. Who would do something this strange? Very suspect

100% - unfortunately, most people just don't realize this stuff. @@IntegrityMeansAll

Why not? They are 100% correct on this issue and I am providing multiple opinions from multiple different sources.

Hello and thanks for the question👍 1) 550 sq. ft. with 8 ft. ceilings? An IQAir HealthPro Plus should be able to do a very good job + you will get superior filtration for ultrafine particles which are the most dangerous to our health long term. The pollution from street traffic also contains small particles. The GC doesn't filter particles as well as the HPP so I prefer people go with the HPP if they can because of it's elite particle filtration. I've had a HPP in a room about 350 sq. ft. with new paint on the walls and new carpet offgassing a lot and it did a really good job. So, I think it would probably do a great job in 550 sq. ft. for VOCs and particles. The HPP has about 5 lbs. of carbon and the GC has about 12 - but it is the same type of carbon in both. Also, if the carbon gets saturated in the HPP - you can get a replacement carbon filter for $99 - and I think that is very reasonable. That is what I would try to do if I were in your shoes. That said, you know your environment better than me and if you think the HPP carbon would not be good enough - then you could go with the GC. 2) Dyson is really coming out strong with that new unit, huh?😄LOL! I will eventually be checking that unit out in the future - it does look like an upgrade from some of their other air purification offerings in the past. They got embarrassed a few years ago with their air filtration fan on a Canadian TV show so I think they decided to really try to "Up their air purification game". And I am happy to see they are really trying to improve their air purification offerings - kudos to them. That said, I don't have much confidence that it performs as well as IQAir units... but I'd have to really "check it out" to get a better feel for it. It's not easy to "shift gears" and suddenly mass produce a "superior air purification solution" when it really isn't a category a company has a strong history on, IMO. Thanks and Good Luck! 👍

@@AirPurificationEducation Thanks so much for your reply. Coincidentally, after noticing a comment in one of your videos (that the HPP was better than the GC for fine particles), I concluded that I could do just almost well with the HPP for VOCs by simply replacing the charcoal filter more often (probably every year). P.s. My ceiling are 9" so that gives me a little over 3.7 full air exchanges per hour (with then HPP). I should also mention that I got caught up in the new Dyson hype and ordered one about a week ago. Then, as I went down the air filtration habit hole and learned more and more, I realized it was probably a mistake but... they have a great return policy (and will pay for return shipping) so I might as well wait till it arrives and give it a try.

@@AirPurificationEducation Also, It's quite fascinating that, people with authentic know how (like yourself), stand out from the KZfaq pack with the sheer integrity of their words. I've encountered this a few times and was able to recognize expertise purely on the "gravity" of the words (without having to know the credentials).

1) Yes, I'd def. try to go with the elite particle filtration of the HPP and maybe swap out the carbon more often if need be. 2) I don't know for sure how the new Dyson performs so I don't wanna be a naysayer without actually learning more about it but I have seen it on 2 "Best Air purifier Lists" on YT and they amazingly were chosen as the "Top Pick" on both lists... and my kneejerk reaction is that makes me believe they are financially incentivizing $$$ the "content creators/influencers" to push their solution. I could be wrong but I do know this is how things work with most content creators.... and if I was the VP of Marketing for an Air Purification manufacturer - you better believe I'd be throwing some cash at the influencers to rank my unit higher... for SURE - LOL! 😆 3) Yes, please tell me how you like the Dyson - it looks like they really tried hard to make a good solution and I do applaud them for their massive efforts as it appears to be a complete overhaul which takes a lot of time, money and trial and error. 👍 @@nternalPractice

That is very kind of you, however - as I like to say, "I am a Student" in this industry learning a little more every week. "Air Purification Education" is actually, to a large degree, ME getting educated and offering up what I think may possibly be true. I think there are probably very few true experts in the world in any industry, lol😄
