Hey Christopher thank you for your kind words and your inquiry. I am not a fan of the Dyson purifiers, in general. And I do like the Coway Air mega 300/400 and Mighty units in general, for your type of issues - as lower priced options. I do not know how great the 150 is but yes I do consider it to be a 'budget' solution. If I were you - I'd be looking at the Aeris 3 in 1 unit as it filters better than HEPA and has serious filtration for particulates. I currently consider the IQAir Healthpro Plus and Aeris 3 in 1 unit as the best mass-produced particulate units I am aware of. I've seen people in the past with breathing issues definitely improve when they moved from a lesser unit to an IQAir HealthPro Plus (many times w/ many people). Most air purifiers on the market that say "HEPA" don't actually work at a HEPA level but the 2 mentioned actually do... and filter even better than HEPA. And I've heard of people with allergies who used IQAir - breathe even better when they replaced it with the Aeris unit in their space... So, the #1 unit I'd go with is the 3 in 1 and try to get a lot of air exchanges in your room. Just like I super-sized my Austin Air unit for my bedroom to get 8 or so air exchanges an hour... I would try to do the same if I were in your shoes. Also, I'd look for some holistic solutions to help with your hayfever... Maybe research "holistic hayfever solutions" or "all-natural hayfever solutions". My wife had horrible allergies in the past but she took something called Noni for a few years and every year her allergies lessened until now they are about 10% of what they used to be. That said, if she goes outside without a mask - her allergies can really act us. So, realize when you go outside - you get all the allergens on you and in your system... and it is hard for even a great air purifier to solve it... I do believe a lot in holistic/natural solutions for alleviating a lot that bothers us. Hope this helps. Good luck and thank you! 😃

I had spoken to the owner/creator/engineer of the product a few years ago - when it first came out in the US and he said it filtered particles just as well as the 3 in 1 unit and that is elite, IMO. But, it has very little carbon and I think the benefits of the carbon would run out long before people change the filter. Problem is, like I mentioned before, I don't think iRobot plans on making any more of these units but we'll see. It would be a shame if it was discontinued altogether.

Hello - TBH, I think over 90% of the air purifiers that say "HEPA" don't actually perform at a HEPA level - the industry is not really regulated in this regard as to which units actually perform at a HEPA level and which don't. But I also think that people get benefits from their air purifiers even if they don't work at a HEPA level - kinda like "every little bit helps" type of situation. Any investment a person makes in an air purifier that enables them to breathe in less dust and debris is a good thing, in general. It just depends on what level of purification they are aiming to achieve. Thank you! 👍

@@AirPurificationEducation thanks for your response. Also,is levoit a good brand of air purifier?

@@Adeline9418 I don't have actual experience with Levoit - I've seen it get good reveiws on Amazon so I am guessing it is at least decent for taking particles out of the air in smaller spaces. I think I'm gonna get a Levoit in the coming weeks and check it w/ a review... but right now I really don't know. I do think the Winix 5500 for $117 on Amazon may be a good deal because I have the older version of the 5500 and it is really quite good for smaller spaces - and I paid about $190 for it @6 years ago. And I spoke w/ a lot of folks who benefitted from it. So, assuming the newer version of the 5500 is as good as the older version - $117 is HARD to beat if that is the case, IMO. Thank you!👍

Very good question and I think I want to do a video on this issue in the future. Anybody can make an air purifier - even in your garage and use a "HEPA" filter or material. Then the unit is marketed as a "HEPA air purifier" to the general public. The industry is not regulated, in that - anyone can do this and no one will stop them. The units can have a CADR Rating to try to explain to the general public how effective the units are at air purification. However, if you saw my CADR video - you know the CADR Ratings are basically not reliable. Therefore, the vast majority of air purifiers we see on the market that say "HEPA" do NOT actually perform at a "HEPA LEVEL". I'd guess - probably 95% or so of the "HEPA Air purifiers" we see - do NOT actually perform at a HEPA level. And if some of them do initially perform at a HEPA level when they are brand new (which is when the CADR tests are usually performed) then some of those units will NOT continue to perform at a HEPA level 1 month from that initial test date - or 2, 4, 6 months later. Why? Because as the filters accumulate dust and debris - more and more "dirty air" escapes around the filters into your breathing space. "Path of least resistance". One of the big issues is how well the unit is "sealed" to force the contaminated air through the HEPA filters and prevent any of it from escaping around. This is where some of the high-level engineering comes into play. The Aeris Founder has a master's degree in engineering from MIT - he is no joke - a really brilliant guy. Not just anyone can manufacture these types of solutions. This is what separates IQAir and Aeris from most of the others... Basically, no air gets around the filters on those 2 brands and they filter BETTER than HEPA (Healthpro Plus, 3-in-1 and Lite). So, my definition of "Medical grade" - is actually "Better than HEPA" performance. And not just today but 6 months down the road when the filters are pretty dirty. So yeah, I think I need to explain my definitions better - you have made me realize - thanks for that. I've sold over 50 different brands of purifiers and have dealt with 50-100 different hospitals all over the country but they ONLY buy IQAir HealthPro Plus units... NO other brand... That is one of the reasons I call IQAir "Medical Grade". The US hospitals I dealt with wouldn't ever look at any other brand. It is very difficult to make an air purifier perform at a true HEPA level and even more difficult to maintain that level of purification months later w/ the same dirty filters installed. Most do not - but some will "approach HEPA performance" which can still help many people. And the more CFMs the unit possesses - the harder it is to maintain HEPA performance, as well. I've seen tests on good air purifiers like Austin which is considered "HEPA" (and I have 3 of them) where it performed worse on Medium Speed and even worse on High Speed with a particulate counter. Basically, not at HEPA levels. This is where the real engineering takes place. 1) Being able to actually filter at a HEPA level - or even filtering BETTER than HEPA 2) with dirty filters after months of use AND 3) with High CFMs... Now THAT really takes some real high-level engineering, IMO. Not just the seals inside the unit but we can all see the IQAir and Aeris HEPA filters are very unique - LARGE and THICK to accomodate world class filtration AND simultaneously enable a lot of air exchanges with high CFMs. This separates the men from the boys - the elite from the garage guys. The Brilliant MIT World Class Engineers creating Elite purification solutions vs. me slapping a HEPA filter in a box with a fan and making it look "pretty" and adding additional "Features". The "Doug Z. HEPA Delight" with 5 different levels of filtration - a TRUE HEPA filter and more buttons and lights than you can shake a stick at... - now on Amazon for $127, lol! Most brands just slap a HEPA filter in a box with a fan and boom - there's your "HEPA air purifier". Many consumers like attractive units and "additional features" like lights and buttons and phone connectivity, etc. For example: we see a $130 "HEPA Vacuum" on Amazon... and it is bagless... do I think it actually performs at a HEPA level? I'd bet ALL my money, it does NOT. - I won't go into details as this response is becoming way too long but I have a $550 Nilfisk GD930 which was 3rd party tested and "Mold Remediation" approved for the contractor industry. Does the $130 HEPA vacuum perform at the same level as my GD930? There is no way. Nilfisk manufacturers Industrial vacuums - even $20,000 and up, high-end vacuum solutions for manufacturers - even explosion-proof solutions where people's lives are on the line - and even more importantly - lots of expensive inventory could be damaged, LOL.... so their units are 3rd party tested by multiple US and International agencies to make sure it does what they say it does. The $130 HEPA vacuum - not so much. But it is cheap, pretty and says "HEPA". Well, I know I went too long with this... I absolutely blame my Vietnamese coffee... - so you can read this answer b4 going to bed at night - It should put you to sleep very quickly, lol! Thank you! 👍

I don't have experience with the a332 - but based on what I see on Amazon my initial Knee Jerk reaction/opinions are: 1) I generally like the Winix brand as we've had the 5500-2 for over 6 years and I think it is one of the better "less expensive" air purifiers for small rooms for particles. 2) This unit kinda looks like they tried to emulate/copy one of the the popular Levoit units (seems many units look similar to this design). 3) How great can an air purifier be for about €89? I think it will help in smaller spaces for some larger particles - I'd be very surprised if it actually works at a HEPA level but if it improves your air quality by even 50% - I think it would be worth it considering the price. Most air purifiers will be able to help with larger particulates in a space if sized correctly - even if they are inexpensive... Even a Box fan and a MERV filter would help with larger particles. 4) I wouldn't expect this unit to be just OK at best for odors. 5) And here's the big issue - many folks may prefer to invest in more expensive - better filtering air purification solutions that help filter more of the UltraFine particles - as they will hurt our health more so in the long run. Scientists and Doctors are realizing that Ultrafine particles can go directly into our bloodstream and access every organ in our bodies including our brains. And there are recent studies linking Ultrafine particles to Cancer, Cardiovascular Disease, Autism, Diabetes, Alzheimer's and more... So, I just want people to understand the implications of Ultrafine particles as it is a very important issue to be aware of. It is kind of like a "silent, slow, destroyer of our health" over time. 6) Now this Winix unit is not going to do much for the Ultrafine particles, I am assuming. But if you are OK with it mostly filtering some of the larger particulates in a small room - then it may meet your wishes. If you have serious asthma or allergies or real odor issues to take care of - I don't know how much it would really help you. But, if you are OK with it "filtering some of the larger particles in your space" and you may possibly notice an improvement - then I think you may be happy with it... --- Good Luck and Thank you! 👍

I think I would prefer the Winix 5300-2 over both the 2 units mentioned. Sorry but my YT comment section started to get messed up yesterday and I can't answer all comments on the site - but I get emails on them, lol! Thanks!

I think you could have probably done much worse, , lol! Thanks!

Hey Brian and thank you for your inquiry. I currently do not have any experience with the Levoit products so I honestly do not know. Based on what people say on the internet - they seem to be decent solutions... I do have experience with and I do know the Coway Mighty and Winix 5500-2 are less expensive, good units for dust and particulates in smaller rooms up to about 300 sq. ft. - I've had a 5500 for about 6 years... So, I do like those 2 units - Thank you!

@@AirPurificationEducation thanks for replying back, I know about winx and coway only problem I have with both they have ionizer. I know you can turn them off but rather just avoid it plus electric cost to run levoit is a lot less. That why I like the levoit. One more question I am better off to oversize the air purifier so even at low speeds it's moving a lot of air or stick correct size for the room.

@@ChiefBrianIrons I generally tell people it is best to 'Super Size' the air purification solution for their cubic footage. The manufacturers definitely tend to 'overstate' the spaces their solutions can do a good job in/accommodate (oftentimes because they feel they have to keep up with the specifications of the competition - in similar price ranges). Also, sometimes/oftentimes the 'CFM' variable provided in the specifications is without the filters installed, lol! So, I generally tell folks to assume they need 20% more CFMs for their space than what the manufacturer states. I have an Austin Air Healthmate in my bedroom and the manufacturer sometimes states it can do up to 1500 sq. ft. but folks in the industry kinda rate it at about 800 sq. ft. - to do a good job (@ 3 air exchanges/hr.). I have less than 300 sq. ft. and I run mine on high as I like the white noise and it provides me something like 8 air exchanges an hour... So, Yeah, I'm doing pretty good! I don't want my solution to 'barely' get me 3 or so air exchanges... So, I know I'm getting pretty clean air in my room most all the time and I AM WORTH IT, lol! 😄 This is the way I look at it but others may see it differently. Thank you!

I do not currently have any first hand experience with the Atem X unit. That said, based on limited research - here are my initial opinions: 1. HEPA/Particle/Ultrafine particle Filtration: I think the HealthPro Plus filters Ultrafine Particles better than the new Atem X. This unit filters 99% at .003 microns but the HealthPro Plus filters 99.5% at .003 microns. I do not think the X's filters are EN1822 certified (like the HPP filters) 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. I don’t see any mention of the Atem X actually filtering at a HEPA Level (99.97% at .3 microns). Typically, we will see this information with most all air purifiers so I am guessing this unit does not hit those numbers (or they would talk about it like they do with the HealthPro Plus’ Specifications). Therefore, I think the HPP filters HEPA sized particles better than the Atem X, as well. I found this info. on an International Dealer’s website: "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." So, right there... THAT tells us 100% the HPP filters better for particles. 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 CFM are increased past speed 2. And according to their UK dealer - it NEVER actually hits 99.97% at .3 microns. But the HPP definitely does. This info. isn’t really a total knock on the Atem X as it covers a lot more space than the HPP and I would kinda consider it to be more like praise for the original HPP. The HPP was ahead of it’s time and an elite air filtration solution for particles. 2. I think IQAir was somewhat forced to come out with a better-looking unit with "smart" features to keep up with the competition. I am not a big fan of the smart features of air purifiers, in general. Onboard air quality sensors tend to not be very accurate, and I consider a lot of the smart features to just be additional “bells and whistles”). So I personally do not see them as a strong reason to purchase a solution. 3. The Atem X does not possess any carbon in the filter so it won’t address VOCs/Chemicals/Odors. 4. Air Exchanges: The X can achieve 2 air exchanges per hour in 1650 sq. ft. and this IS impressive. So, in 825 sq. ft. we could get 4 air exchanges per hour which is more closely a number we’d like to hit from an air exchange standpoint. 5. 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, I’d say it IS a good filtration solution for particles when you compare it to most other units on the market and it covers A LOT of cubic footage. So, this is what I currently think about the X based on what I'm seeing. Thank you!

Yes. Nilfisk makes good vacuums and the underlying, foundational "genetics" for their "residential" vacuums come from the industrial side as they also make custom industrial vacuum solutions for warehouses and manufacturers costing tens of thousands of dollars. They are basically experts at making high level filtration vacuum solutions for many different environments. NASA used the Nilfisk GM80 "to eliminate microscopic particles from the cargo bay and to remove hazardous beryllium dust from the shuttle’s brakes. NASA spent as long as 56 hours cleaning every inch of the 60-foot-long, 15-foot-wide and 17-foot-deep cargo bay to remove particles as small as 0.3 microns". The GM80 is a popular industrial vac. in their product line but residential customers don't really typically go with that unit. I have had a Nilfisk GD930 for over 10 years. It is UGLY and does not have all the cool and pretty bells and whistles of some brands like Miele but for sheer particle filtration - I would bet my GD930 beats out all the Miele vacuums on the filtration side. The GD930 was "Mold Certified" in the past and we had many Mold Remediation Professionals purchase and use them for mold remediation jobs. Plus, it is EPA RRP Compliant for Lead and Asbestos remediation. So we know the filtration has to be top notch. Most residential customers purchase either the: Nilfisk GD930: amzn.to/3IOhrQ3 or the The VP300: amzn.to/3VOxWU3 The main differences are: The VP300 is about $92 dollars less and has 68 CFMs, a 2.1 Gallon Capacity and a 1 year warranty. The GD930 is about $92 dollars more and has 74 CFMs, a 4 Gallon Capacity and a 2 year warranty. Both units are used for bare floors and low pile carpet environments as they do not come with an electronic head/beater bar. The GD930 has an accessory option (the Nilfisk Turbo Floor Nozzle -01710009) that can be purchased for about $85 which features an air-powered carpet beater bar that spins while the vacuum is in use to help dislodge dust, dirt, and debris from carpets. Hope that Helps - Good Luck!👍

@@AirPurificationEducation wow! I was actually going to buy the GD930! But then saw it only uses paper bags and was considering the Miele C3 instead. Do you happen to know why the paper bags on the Nilfisk would offer better containment than a hepa bag on the Miele?

You did your research very well, IMO. I don't know/remember about the paper bags but I will ask them to see what they say. I also want to know... their response could take some time, though. Thank you!👍 @@GucciDiapie

I don't know about the paper bag issue... but I do know the GD930 is 3rd party tested for filtration and meets certain standardizations for mold, lead and asbestos... so it would be considered "industrial" in my opinion from a filtration standpoint. That said - we had a showroom with a bunch of Miele vacuums in it in the past... and I "demonstrated" some of them for interested people - and they are EXTREMELY nice units and very well made, for sure. Very impressive vacuums and much, much, nicer than the GD930. But, if I had to guess, I do think the GD930 will filter better because it is more of an industrial unit and it absolutely has to meet certain standards. It doesn't have all the great features and accessories of the Miele units - it is just a hardcore "HEPA filtration vacuum". I will be getting more into vacuums in the future and I'll be trying to get into the 3rd party certification issues, as well... but right now, I'm more focused on the air purifiers. Nilfisk replied, "The GD930 bag is a 2 ply paper bag for solid debris only. It doesn't offer the filtration capability of a HEPA filter. The HEPA on the GD930 is further downstream in the vacuum. We don't have comparative data for the the Miele C3". Basically, a generic response. I'm guessing the "seals" inside the GD930 are probably superior but... hopefully, I'll be more certain in the future. BTW, I don't think you would be making a mistake by going with either brand. Good Luck! 👍 @@GucciDiapie

If you can get an AirDoctor 3000 for $200 that is probably a good deal. I suspect they probably filter similarly to the Winix 5500. But I plan on getting one in the coming months to check it out. Thanks!👍

@@AirPurificationEducation so makes no sense to get another winix then lol

1) If you can get a 3000 for only $200 and it covers more cubic footage than a Winix 5500... and I am guessing they probably filter similarly - then no... I would take the $200 unit that filters more cubic footage (assuming the filter replacements are similar in cost)... 2) The Winix 5500 definitely is not good for Ultrafine particles and I don't think the AirDoctor is either. Units like the IQAir HealthPro Plus and the Aeris 3 in 1 are around $900 but they have elite filtration capabilities - namely, they are good at filtering ultrafine particles (.1 to .003 microns). To a certain/large degree, that is what people are paying additional money for... 3) Winix says the 5500 can do "99.99%* of airborne allergens including pollen, dust, smoke, pet dander, and other ultrafine particles as small as 0.003 microns." but I've had the older 5500 unit for over 6 years and I just got the newer one, as well, and I can very easily see the filters are NOT sealed well inside the air purifier so there is NO WAY it is even performing at a HEPA level (99.97% at .3 microns) - let along 99.99% at .003 microns... There is NO WAY it performs at the level they are advertising it - in the real world. 4) AirDoctor has a 3rd party test result on their site that claims their unit performs at 100% at .003 microns and I HIGHLY, HIGHLY DOUBT that is true. Even an elite air purifier that is sealed extremely well like the IQAir HealthPro Plus only does 99.5% at .003 microns... And from what I can see online - the AirDoctor units are not sealed nearly as well as the IQAir units. So, I'll be getting one in a few months to be sure. 5) So yeah - I am guessing there is not a huge difference in performance between the Air Doctor and the Winix 5500 - they probably both perform similarly for larger particles which are LESS dangerous for our health and only comprise about 9% of the air particles we breathe... But the Air Doctor 3000 is supposed to provide more air exchanges - so for $200 - I'd probably go with that... So that is my current reasoning. 6) Tell me how to get a 3000 for $200 and I'll get one sooner than I planned, LOL! Thanks! 👍 @@prtbone78

I am going to eventually get my hands on an AirDoctor and check it out. From what I've seen on YT videos and pictures - it looks like it leaks dirty air just like most other air purifiers and probably does not filter at a HEPA level - just like over 95% of the "HEPA" air purifiers on the market. But I have to get it to be sure. Thanks!👍
