Blueair Blue Pure 211i Max

Scored on 13 verified owner verdicts, from 88 comments read across 5 communities
TL;DR
Owners are split on the Blue Pure 211i Max. Fans love how powerful and quiet it is, especially the way it clears odors, smoke, and allergens from large rooms, and they find the app and scheduling easy to live with. Detractors push back on the price, a build that can feel flimsy, and shaky smart-home integration, so a handful of long-term owners ended up regretting the buy.

69% of 13 verified owners recommend the Blueair Blue Pure 211i Max, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

Ours stopped just over 12 months. It's not worth it! It was too expensive. Not commercial grade.

I just bought one second hand a few days ago. So far so good. Material feels super cheap and not durable tbh. But i just run it on auto. Seems to do a decent job. Just wish it didnt feel like its made of paper lol.

it outperformed others. Voted one of the best for 2024

I bought a Blueair Blue Pure 211i Max and I've not been able to get it working with HA.

I like the design of the BLueair. It has room for improvement for more compact design.

I use a BlueAir purifier at home that I love! It’s a little pricey, but I consider it an investment in my health. I have two double coated breeds and as much as I do my best to keep them well groomed, it’s been a godsend during allergy season! It filters out viruses, mold, pollen, pet dander, dust and more.

Actually it's the sound that I love. Helps me go to sleep!

I had the Coways for 4 years, then switched to the expensive Blueair Blue Pure 211i MAX, which I have stuck with for the past nearly two years (I also bought their predecessor although I forget the model name). Don't make the same expensive mistake I did. The Blueair units suck, plain and simple. They have a very loud fan whir and rattle along with motor hum

It was the BlueAir Blue Pure 211i Max: https://www.blueair.com/us/air-purifiers/blue-pure-211i-max/3541.html If you look at /u/Intelligent-Prune850's comment, I think they're right that it doesn't have anything to do with the PSU or wiring in the wall, but rather maybe having to do with the purifier emitting ions and my computer's intake being very close to

this air purifier even outperformed HEPA air purifiers

Blue Air’s advertising is slimy. To say that the light carbon dusting inside of the filter is effective for smoke or odors is a blatant lie. My unit faintly smelled like an old wet campfire.

Also it is significantly quieter than any other filters I have tried.

Otherwise, the app is great. I’ve had no problems with the unit.

I've had my 211i max for about 2 years now, and i love it.

a month ago, I purchased the 211i Max. I love them all.

I have 2 of Blue air products and they are amazing and by far better than couple of HEPA filtered air purifiers I tried years ago!

It’s not cheap, but the BlueAir Blue Pure 211i MAX is an absolute unit. I kid you not, if you cut a fart in the general vicinity it will spin up and yank that stank right out of the air. The “smart” features are dead easy to set up, and once you set the parameters for “night time mode” (it will darken the display and keep the fan speed low and quiet when it’

I've been really happy with the BlueAir purifiers. I have a bunch of the older 211+ units, and a couple of these 211i Max units, which are even better.

Slickdeals▲ recommend

I have owned this one for a few months and couldn't be happier with price/performance. App control is convenient and automatic mode will increase fan speed if the poorly ventilated oven/stove is turned on for longer than 15 minutes.

Slickdeals▲ recommend

Arrived today, certainly more effective than the Winix C545 (Food odors to be specific) . But this is just day 1.

On the lowest setting and night mode, it's genuinely very quiet—more like a soft background whoosh than a fan.

Slickdeals▲ recommend

I got the 211i max last April and have found it to be great. I paid 230ish at the time and thought that was a good deal. The app works well, and the machine is quiet and aesthetically pleasing. I have about 700sqft in my apartment and it does a great job

The 1st quick setting of 12% is audible, but is unlikely to bother anybody.

So I have had the Blueair Blue Pure 211i Max since late November. I am pretty confident that when viewing the air quality history of the purifier’s indoor PM sensor, the grey line indicates the equivalent outdoor air quality for the location (using Breezometer) you’ve assigned the purifier to.

It has an ionizer?! Kinda messed up that they don't make that clear anywhere besides buried in some blog post on their site. I've had this thing for over a year

Redditⓘ good to know

The Blueair is a bit different, since the filter basically sits on the outer perimeter of the unit and all around it, with just a fabric covering over the filter. If you pick it up around the sides, you're just feeling the filter, right? Which is going to feel less substantial than the framework of a more traditionally built unit, where the filter sits insid
