Blueair - 311i+ Max

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.

Our home is 1200 sq ft with two dogs. We have an Alen Breathesmqrt Classic Purifier in the main living space. We have a Blue Air 311+ in the bedroom and another BlueAir Classic in the master bedroom with an air quality monitor built in. You can notice a huge difference in our home, as we can create a clean room when needed during forest fires. We didn’t have these when the worst one came through Oregon. We love them and our allergies are so much better. We change the HEPA filters every 6 months or sooner. Our favorite is the air quality monitor to be sure everything is getting filtered properly.

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.

We just got a Blueair 311i MAX last week! So far it seems good

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.

We use the Blueair 311i max and 411i max, you can order a slightly more expensive smokeblock filter for them specifically made to filter out the particles in wildfire smoke. These units will also give you a readout on your phone to monitor the air quality in your home.

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.

I have a feeling that only the largest, most expensive purifiers will help and you will need more than one for 1500sqft. And they won't clear the stench immediately. Marijuana nowadays is very intensely stinky and seems to stick and linger. I'm reading a lot of posts about this problem and everyone is in apartments. I'm in a house with a backyard separating my two open windows from any neighbors and that stuff STILL gets trapped inside my house. I am woken early in the morning by it, like a skunk just sprayed in my backyard. And it lingers for hours. I don't know how that's even possible. I'm not even sure which neighbor is doing it. I can't hear or see anything. That's how far away they are. Since I'm in a house I can prevent the problem by closing my windows quickly at the first whiff of skunkiness. I would lose my mind if I could still smell it with all the windows closed. I have a BlueAir 311 and it does nothing at all for odors. Not sure if it does anything helpful. I would like to see laws banning outdoor smoking. That's the solution. And laws banning scented dryer sheets. Those smell like poison and engulf entire neighborhoods.

I have a Blueair 311 and really like it. Very quiet than other brands ive had, including Levoit 

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.
