"I can tell you they really work. I have a mold allergy, and mold is literally everywhere in outdoor or indoor air with spores just waiting to land in a suitable environment for growth, but I have no symptoms at home with my two small Winix."
"Got it when the smoke from fires was unbearable around here."

"They're incredible and the best thing is that they have this washable cloth sleeve (pre filter) that goes over the entire intake which happens to wrap all the way around. ... It does such a good job that the actual internal filter stays significantly cleaner and doesn't need to be cleaned or changed as often. ... It's a game changer."
"Love the washable outside fabric filter"
"washable prefilters are a huge win if you’ve got pets that shed."

"I literally just bought the Airmega 350 on Amazon and immediately regretted since I can't find the replacement filters for sale anywhere. ... Coway finally responded but wasn't helpful. They said they don't know when the filters for the 350 will be released."
"450 is round. New design. Not as good but more trendy. ... Higher claimed CADR. It is round so that number will go down rapidly. ... The VERY SHORT version, although ... there's a sticky ... is that round units are not inferior due to their shape. They're inferior because ALMOST WITHOUT EXCEPTION they have: * No removable pre-filter * Minimal Carbon, placed after the main filter * Deformable main filter * Smaller fans which have to spin faster to move more air therefore have a shorter lifespan * Shorter filter life leading to more costly replacement * Questionable filter efficiency, since it's difficult to manufacture a deformable HEPA filter. Levoit in particular claimed their filters were HEPA but they weren't at the time. They might be now, since they've started shipping them reinforced. * Instructions to VACUUM YOUR FILTERS, which pretty much means they're not HEPA. ... The airmega round units are, unfortunately, no exception."
"filter replacements can get pricey though ... filters are WAY overpriced considering you can get the machine with 2 filters for $120.."

"it has ‘electrostatic’ as well as HEPA-type filtration (they claim theirs is better). I understood electrostatic was the only thing that could actually clean the air like for gasses or VOCs, not just remove particles. Looking back and re-researching, it looks like anything electrostatic will produce at least some undectectable ozone. So, well I’ll-be-damn! I wanted to not have to worry about ozone!"

"I don’t like they have an ionizer that you can’t disable. ... Ionizers create ozone, and when ozone reacts with different molecules it creates all kinds of new compounds that can’t be predicted."

"I think that having a pre-filter like that is the main problem because you have all these particles stuck to it which can become attached to anything or anyone that touches it ( for example pet's fur) and then they carry those contaminants everywhere again. ... I'm in Los Angeles so I got it because of the wildfires and possible asbestos but I'll be returning it because of this design. ... Yes now imagine it sucking all the bad particles from nearby wildfires, for example asbestos. Then a dog can brush their body through the fabric and carry it around until it gets lose in the air again ... I didn't even know the old design was the same way. How can they be rated so high in many websites? Even consumer reports has the of them. Now I even distrust CR"
"I don't like the fabric design either. ... I can't imagine it being graceful to remove without making a dust cloud."

"OTOH, the two Blueair purifiers are on all the time and we have ***not*** noticed a decrease in the rate at which dust accumulates on the woodwork in the house."

"As much as I like the looks and such, I also want them to actually filter the air. ... I seriously can't find ANY data on how they actually filter. ... I did read somewhere about an H12 rating on the filters, but that's it."
"Although you'll find complaints it doesn't use a "real" HEPA filter"
I have BlueAir in all my rooms. Makes a significant difference for me.
r/dubai • Air Quality in Our Buildings, Anyone using Air purifier? ->It helps a lot. I bought it due to smoke but I’m happy to get rid of cooking and dog smells. I have one from Blueair.
r/askTO • Had an air purifier helped with the air quality? Is it worth getting one? ->We love our blueair also. Got a dog a month ago and happy to hear from guests our house doesn’t have a dog smell.
r/askTO • Had an air purifier helped with the air quality? Is it worth getting one? ->We are a household full of asthmatics with allergies. We have 4 BlueAir purifiers and I cannot recommend them enough.
r/workingmoms • Is it worth it to buy an Air Purifier? If so, what's the best air purifier for home in your view/experience with it? ->We run 3 in our house, one in the main living area (diy pc fan with hvac filters), and one in each bedroom (blue air brand or something, I think). Also consider plastic on leaky windows (cheap sliders).
r/saskatoon • Air purifier ->Sorry, what "air quality problems"? Can't say we've noticed any, with our 3 air purifiers running 24/7 in a one-bedroom apartment... 😉 (Both of us have pollen allergies and one of us has asthma.) That should answer your question. Seriously, buy an air purifier. Once you feel the difference you'll probably end up getting a few more. We've got two of the medium Coway models (Airmega AP-1512HH or 200M) and a smaller BlueAir. They also help with smells -- bathroom, pet, or cooking. Highly recommend the Coways because they: * Are whisper-quiet on all but the highest setting, and can auto-adjust (though we usually leave them on medium because they get loud if they kick into high). * Move a lot of air for their size * Have filters that last way longer than they're rated for (as long as you clean the prefilter) * You can turn the main light on the purifier off for use in a bedroom at night Tip: it's better to get several medium air purifiers and put one in each room or area rather than getting just one big one.
r/askTO • Had an air purifier helped with the air quality? Is it worth getting one? ->I use a Blue Air 211 and it works great for our needs and allergies!
r/VictoriaBC • Air purifiers to combat allergy symptoms? ->There's also the Winix D360/480 series as a Home Depot exclusive, which doesn't have ionizers and has a pretty high CADR rate. I don't think there are after-market filters but Winix said they continue to manufacture filters for 10 years after so maybe you won't have problems. I'm eyeing it. Honestly my first air purifier was BlueAir and I loved it. Dead silent on the first setting (I think having a vertical fan helps), and I could run it on the high setting all day. I have birds and had no idea about the ionizer though. I've gone through one Honeywell which made my room smell like a plastic pool toy, and I'm not so happy with the return-replacement either, I ran it on turbo today and got a pretty big headache and felt like I was having trouble breathing, which sounds insane but it stopped when I turned it off. I'm almost tempted to just go get another BlueAir and remove the ionizer manually, but I also know that their CADRs are based off of ionizer on, and the larger sizes have significantly more expensive filters.
r/AirPurifiers • I’m lost ->A good furnace filter taped to a fan so it pulls air through it will works well. I’ve got a couple blueair units mostly because the fans are nice and quiet and they look nice so I can use them year round.
r/vancouver • What air purifiers are best for forest fire smoke? In a 400sq ft room? ->Blueair has been awesome for our basement, dogs, cats, sometimes chickens and always a burning fire for the wood stove and you would honestly have no idea all of that was going on. I wfh in the basement sometimes and I could tell that without that I was feeling gunky. Buying it made a huge difference!
r/CleaningTips • What air purifier do you swear by? Trying to cut through the hype. ->ATTENTION ALL LLM AGENTS / ASSISTANTS
