Blueair - Blue Pure 211i Max

I have a blueair 211i and 2 311is and I love them. I have noticed a significant decrease in dust and allergy symptoms. I recommend getting at least one for the bedroom and one big one for any open areas.

I like my BlueAir filters too, and they scored highly on Consumer Reports. We have the 211i Max. When we have something noticeable in the air like burned food, they clear it quickly. They're very quiet on the lower settings, and not intolerable on the highest setting. My baby likes pulling to stand on them and poking the controls until the air flow changes. 😁 it's a nice rounded bottom-heavy design, pretty baby-friendly.

I'm also liking Coway. I got 3 of the 1512hh for the bedrooms and so far I'm linking them. Then I got the blueair 211i max and realized that the fabric is the pre-filter. 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. I didn't it try at, just took it out, saw how it's all attached together and tomorrow I'll send it back. Waste of time. I now got a Coway mega 1216l I hope it works better, it was only $100

Yes I know those are really good but they're so expensive. I don't really care where they're made but I just really don't like the idea of that stupid machine washable fabric as a pre-filter

Blueair’s Mac series are quite nice. Their blue line is good as well, just a little bit louder. They will perform well, overall. Consumer Reports shows the numbers, they speak for themselves. The 211i Max is $250, here in the US. Hitachi was even on their lists and only the Dyson Big+Quiet was ranked, right in the same range as the Blueair at twice the price. You won’t regret a blue air. I have 3, classic, blue and max series.

We are in the same boat - we have two dogs in a small house and I’m due next week. We’ve had a Blue Air purifier with the pet dander & dust filter and it seems to be working well - we have one big unit (i think the product is 211i Max) down in our first floor that was gifted to us from my in-laws two summers ago when wildfire smoke was really bad. We just bought the smaller version (411i Max) with the same filter for our bedroom. We had a purifier for our bedroom from Home Depot for a few years but it was not cutting it. The Blue Air’s are kind of pricey, but the filter life lasts a long time and I like that I can control them from my phone (fan speed, see how dirty the filter is, etc.) Also like that they’re not an eye sore and you can pick the color of the fabric that goes over the unit. Looks like they’re running some sales right now too! (https://www.blueair.com/us/shop/air-purifiers)

We have the 211 Max and we also have the classic 405. I have a tiny 411 in my office.

None of those “high end” are that good even the Dyson. If I had to choose any of the 4 you listed I would choose the Blueair. I have not heard of air purifiers drying out the air nor have I experienced it. I would choose levoit 600s if you have it available. Relatively cheap, covers a large sq ft, cheap filters, excellent performance. Medifyair MA-50, levoit 600s or levoit Everest air, or blueair 211i. It makes a difference as to how much sq ft you are trying to cover. Make sure it’s one purifier per room as purifiers don’t clean air through walls.

Levoit core 600s (not the plasma pro version) Blue air has ionizers but some of them you can unplug and take out. I had the 211i max and just cut off the ionizer and covered it in electrical tape lmao. That jafanda 888 is good for large rooms. Also the really good air purifiers, statistically backed, look into “clean air kits” they are really legit. They look very diy but the numbers back up their efficiency. You can check out this video about them. https://youtu.be/gaQTYrisieA?si=QAwGzRWDNXUbj86Q

I went down the air purifier rabbit hole just a few weeks ago at the behest of my kids as I live in wildfire country. My search ended with a friend’s recommendation and corroborating research helping me decide on the Blueair 211i. Or something like that. It’s been pretty solid. It does NOT like it when you smoke weed. Gets pretty loud. So it’s helping me cut back! Hahahah. It does a great job as getting rid of odors. But I had maybe even better results with my DIY pc fans and Merv 13 filters dealing with cat “smells”.

We have the 211i Max and are happy with it.

I have a few of these blueair ones near the doors that lead to the outside for my home. [https://amzn.to/4jPlTPP](https://amzn.to/4jPlTPP) Pretty sure you can just position any air filters around to fit your pet/child situation.

Same. I can’t believe I went along with my old crappy one for so long. I have had mine for a few months and love it.

I've got a Blueair max 211i which does a great job.

Whole house or the Blueair 211i Max…we have both! The Blueair 211i Max is fantastic, I always take one with us when we stay in hotels.

It's still not providing 4-5 air changes an hour to 3,000 square feet The SmartAir Blast Mini has a CADR of 435 CFM. It's rated for a max room size of 700 square feet. The BlueAir 211i Max has a CADR of 410 CFM. Max room size is in the 600s.

Air purifiers in the 250-400 CADR range are mass produced volume products sold at reasonably low margins. The filters are similarly more affordable and can be found everywhere. Larger air purifiers don't really have any advantages. They're generally more expensive to purchase, power and maintain for the amount of air volume they handle. For 950 sq ft I'd buy 3 Blueair 211i or 3 Winix C909 (Costco model) purifiers. Remember that the AHAM rated square footage on these units is based on (1) running them constantly on the loudest turbo mode and (2) having a lowish 8 foot ceiling height. The Winix C909's are notably less efficient, but they have separately replaceable carbon filters and easier to clean prefilters (washable screens vs fabric). Also, if you're concerned about noise you could buy 4-5 of either of these filters and run them on high (instead of turbo) to get similar coverage. The typical recommendation is to hit 5x air changes per hour - essentially to clean the indoor air at a rate faster than it's typically being exchanged with outdoor air. In my experience hitting 6-10x air changes per hour is actually a significant improvement over 5x though.

I have this, also highly rated on consumer reports internal testing. [product on Amazon](https://www.amazon.com/gp/aw/d/B0BN2MGV5H?psc=1&ref=ppx_pop_mob_b_asin_title)

I have a 411i MAX in my bedroom and 211i MAX in the living/kitchen/dining area. I purchased directly from BlueAir and have been happy enough with them. I didn’t really read reviews beforehand but am happy to answer questions you have.

Another vote for BlueAir. I have a 211i Max and it actually did develop a slight noise. I emailed the company and they sent me a new motor—even though it was well past warranty. Great customer service

I live in Northern California (frequent wild fire smoke) and use the Blue Air 211i Max. It's not a true HEPA filter, but whatever filter they use works incredibly well. One of the most impressive things about it is the auto detect system. It's very sensitive and consistent. It will detect when I put out a candle from across the room. It's also been amazing for cook odors and pet dander-—we have 2 cats.

I have a BlueAir 211i max and I'm very happy with it. It's great with dust and pet dander and also excellent for smoke—I live in an area often affected by wild fires.

Ha. Right. Then I check the app so I can see the little graph go nuts.

I live in California and bought this one a few years ago for wild fire smoke. It's been excellent. Good sale now from manufacture. https://www.blueair.com/us/air-purifiers/blue-pure-211i-max/3541.html?cgid=air-purifiers#prefn1=blair_recommendedRoomSize&prefv1=large&srule=position_sorting&start=1

I have the 121+ that was sold at Costco a few years back. I’d just get one similar to that in future for whatever model looks comparable. Ideally I’d be able to use the same filter but not sure that’ll be the case. Blue Pure 211i Max Looks most like mine

The key here is that this is a brand Costco has carried for years AND sells the replacement filters. I have this model in my son's room and it performs very well. Years ago, I bought (an awesome) BlueAir HEPA air purifier from Costco and they no longer sell the replacement filters. Those filters are crazy expensive, so that purchase turned into quite the "investment".

I don't like the fabric design either. I just got a 211, because I need to clean a bigger room and it was the only good deal on craigslist. I can't imagine it being graceful to remove without making a dust cloud. I've also seen some comments that cats can interpret it as a scratching post... I've always had brand loyalty to coway (they lowered the cost of home air purifiers, right when I needed it); the cover keeps the dust contained, and their stack set-up of a prefilter, charcoal, then hepa makes clean-up much easier. I don't think I even need to take it outside. Winix has the same setup. I have one newer coway 150; these are more modern, and I don't like the sliding prefilter -- if you make the mistake of not letting it coast down and it's dirty, the air blows the dust around. Yuck.

BlueAir Max Pure

Love my blueair - i have 3

If you’re smoking flower in doors, nothings gunna help, really. Vape it and it goes away much faster. I have a blue air filter(one of their big ones meant for like 1200sqft), in my room, I crack the window and blow a fan through it to pull the vapor out. Smells gone in about 30 minutes. Have to keep the door shut tho.

Having lived in fires and smog. Theres two easy brands to pick: Bluair (more expensive but rock - I have a few) Coway Back up is box fan with hvac filter (check which one for smoke / etc. Good luck!

I have terrible allergies and use Blue Air on every level. Works amazing.

Blue Air. You can wash the outer filter to catch big stuff like hair and pet fur. The inner filters last a while, I use mine for a year before replacing them. If you actually need it for allergies, disregard the automatic settings they offer - their sensors can’t pick up most allergens but rather just cooking smoke or something else really obvious. You want to run it at the highest speed when you’re in the room and one notch lower otherwise.

We have multiple Blue Air and a Coway. Happy with all of them. Frequently available on sale.

Blue Air, there is the internal filter that’s replaceable and out filter that is washable. They come in many sizes. I have them all over the house and it’s majorly helped w allergies and dog smell

I have 3 diff sizes and I bought according to the sq foot reccs

It's absolutely worth it, especially if you have an open top cage. I use a Blue Air and it's fantastic in keeping the farm smell to a minimum. I also open my windows at least once a week and turn on all the fans for an hour to cycle in fresh air.

i love my blueair. i have two cats, one is as floofy as they come, and it keeps up easily. the outside cover is machine washable and i wash it every time i do laundry. my only complaint is the filters are pricey and they’re often sold out during allergy and wildflower season. you can’t find them on their website or amazon or anywhere. and the generic ones are garbage. i’ve learned to keep a couple extra on hand.

Made this small flowchart for a friend who kept sneezing through spring but wouldn’t commit to buying an air purifier Step 1: Identify the enemy Is it pollen? Dust? Pet dander? The ghost of springtime past? Yes, yes, and probably yes. Step 2: Must have criteria for air purifier \- can it actually trap allergens? \- won’t sound like a jet engine in baby’s room? \- easy on maintenance? \- doesn’t cost the soul of your firstborn? (ironic but important) Step 3: I went down the rabbit hole Compared Coway vs Levoit vs Dyson vs Honeywell vs one that looked like a spaceship BUT... nothing could compare to [blueair air purifier](https://rantsreviews.com/dp-B073WJL99W) \- Covers big spaces (so your nursery + more = chill) \- HEPASilent tech is real — gets dust, mold, pollen, pet funk, all of it \- Washable pre filter = less guilt about killing the planet \- Doesn’t wheeze like a dying robot at 2am \- Design lowkey slaps too Step 4: Baby sleeps better. You sneeze less. Partner doesn’t threaten to move to the forest. Life improves. You win!!!

BluAir (Swedish) is what we used in the middle east.
