Blueair - Blue Pure 311i Max

You might not be able to get a commercial one that makes things nearly sterile, but I have had luck with both of these (I have a highly reactive airway, am allergic to the cats in the house, and asthmatic): [https://www.amazon.com/gp/product/B0BN2LZ9JH/](https://www.amazon.com/gp/product/B0BN2LZ9JH/) \- Only thing to note, it does have a nice little cover on it, but if you want it to work the way it should, you have to remove it. Leave the filter visible and exposed and it works really well and lasts a very long time [https://www.amazon.com/gp/product/B00D52E2XG/](https://www.amazon.com/gp/product/B00D52E2XG/) \- This one keeps my office clear. It used to be in my bedroom, but I didn't have enough floor space for it when I started working out so I got the above one which sits on my dresser. It has gotten me through more than a few stagnant air warnings here in the pacific northwest (when winter smoke, smog, and fine particulate are suspended for long periods of time in the air due to a lack of air movement)

Own Levoit 400 for our main living area (1,100 sq ft apt), the smaller one in our bedroom (toddler sleeps with us). Had them prior to Covid and love them. I vacuum the filters when I can per the manual. I got my mom the blueair 311i max because she was closer to one of the “minor” fires here in LA and she loved it so much she got the mini for her bedroom along with my dad’s (they sleep in separate rooms lol). I ended up getting the mini to bring to work.

I have the 311i max and I really like it. I never knew air purifiers could be so good. I always thought it was a scam until I used one and noticed the difference. I have one in my living room and when we fry onions or something similar it goes off right away. Never knew they had an app.

I have the 311max and it is garbage, I refer to it as a fancy fan

What about brand names "hepa" filters like the blueairs "hepasilent" or airdoctors "ultrahepa" filters that use electrostatic and other forms of collection? We just picked up a blueair 311i max from target that was on sale for 159 usd. We are going on a mold prevention spree in our home in south Louisiana due to mold allergies with my kids. There's so much stuff out there to read through my head feels like it's going to implode lol. I just want something that will collect mold spores out of the air. I feel like if it can capture mold spores it'll get everything else also.

I'm a fan of blueair. WiFi controlled and you can see an air quality graph on the app. You're better off getting two medium sized ones placed somewhat equidistant from the center of the home. 311i Max I think I have. I've had a couple medifies that both broke. And since I was using 3rd party filters, no warranty coverage.

We have this one in our bedroom https://www.blueair.com/us/shop/air-purifiers/blue-pure-311i-max/3539.html Blue Pure 311i Max for medium rooms! Looking online it looks like they've updated the model a little bit, but looks to be relatively the same! The filter we have on auto subscription is for this one too so couldn't have changed too much. We got the Pure 511 version for our nursery though since it's a pretty small room.

I saw a youtuber that tests corsi rosenthal boxes, he uses a Blueair 311i Max as his standard to compare against, so I bought the Blueair. It works great and has partially-working Home Assistant support.

I can also vouch to BlueAir customer support. I bought a second-hand air purifier and found out it was malfunctioning (weird noise coming from the motor). I sent over an email to suppport after having asked the seller for the receipt and they were able to send a new unit to me even out of warranty. Well, what happened to that unit? IT GOT STOLEN FROM MY PORCH. So I contacted BlueAir again. And they sent me a new one, AGAIN! As to the actual purifier, it's a 311i Max, it looks great and seems to work fine too. Have noticed less dust in the room it's at. It's pretty powerful but my rooms are all closed off from one another so doesn't help much for other rooms, however.

I have BlueAir purifiers. We bought them after I tested positive for mold exposure. I’m pretty sure mine are the 311 model, though it does look like they’ve released newer ones. At the time we did a bunch of research and these were the best on the market at that price point. But that was around 2020/2021 I think.

You’ll typically see the same top-rated models across Wirecutter, Consumer Reports, and Tech Gear Lab: the BlueAir Blue Pure 311i+ Max, Coway Airmega 1512HH, and Winix 5500. The best choice probably depends on the size of the space you’re trying to cover. For my downstairs rooms, I went with two BlueAir units (the 311 and 211 models). BlueAir offers a 25% discount for teachers, military, police, and possibly firefighters (can’t recall for sure), available in both the U.S. and Canada. They also offer a 15% discount on filter replacements if you sign up for a 6-, 9-, or 12-month subscription. For my upstairs office/bedroom—since it’s a smaller space—I went with the Coway Airmega 1512HH and have been happy with it.

A 311, a 211, and a 7470. It's best to size up and run on low (auto). The other benefit is the larger ones tend to be quieter.

Just got a 311 and can confirm my cat has scratched it a few times.

I mean.... I mentioned the part about them having no reviews and being at a sketchily low price point of 1/2 to 2/3 the cost of everyone else. There are really only a handful of air purifier brands that have demonstrated reliability, affordability, and effectiveness over several years, and don't dabble in post-apocalyptic/steampunk decor -- coway, levoit, blue air, winix. If you want to pay more, there's iq air, alen air, and a few others. For $110, you could have bought a blue air 511 and almost a 411, a levoit 300, almost a Levoit Vital 100s, or a Winix a231. The winix 5500, the coway 1512, levoit vital 200, and the blueair 311 are all at this CADR, but for closer to $200.

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".

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.
