Blue Pure 311i Max Air Filter

Home>> Blueair Blue Pure 311i Max Air Filter

Blueair’s signature performance is now even better, delivering up to 83% more cleaning power, and removing harmful particulates like pollen, cooking odors, dust, pet dander, mold, bacteria, smoke, and chemicals.

Their proprietary HEPASilent technology combines electrostatic and mechanical filtration to capture at least 99.97% of airborne particles down to 0.1 micron in size².

Air purifiers can also make a big improvement in air quality during construction. Because of the heavy load from all the dust and fumes, Blueair Pro air purifiers are a good option. These air purifiers offer powerful air purification performance in a small space. All Pro models are solidly built, with a galvanized steel housing, and backed by an extended warranty.



The Blue Pure 311i Max is an incredibly feature-rich air purification system and environment monitor that truly hits all marks. As you’d expect, the device can cycle through three fan speeds and has an auto mode. The overall noise produced by even the highest setting is nominal, which is great, and the LED is dimmable. What I particularly love is what I didn’t expect – this device is connected to the Internet so you have a wealth of information available at your fingertips, even if you are miles away from the unit. Among other functions, I can review outdoor air quality over a continuous timeline, and check in on my device’s status and performance across time. Within the app you can also define a schedule for the unit, so it need not run while you are gone but you can also set it to resume air purification a period of time before you are expected to return. Everything is intuitive to operate, and each feature is so well considered and designed that I can’t imagine anything I would change. My son suffers from environmental allergies and on day two of our experience with the Blue Pure 311i Max he reported far less congestion and asked why we didn’t get the device years ago. I’ll be soon populating all of our bedrooms with these units – they are simply just that good! I’m extremely impressed and hope you’ll improve your own air with Blueair – especially if anyone suffers from allergies.


It’s a little bigger than I expected but not in a bad way! It’s light weight and quiet. It has an automatic setting, night time setting, and 1 to 4 speed setting depending on which you prefer. It also has an indicator light that changes colors depending on what your air quality is. A really neat feature is wifi capability that connects the product to an app you download so you can track the air quality, change settings, and life of the air filter. I have mine in my open living room and it’s doing really well!


This is the third air purifier I own and by far the best! I’m easily pleased with the overall production of this product. I keep my Blueair on a steady 48% fan speed and you can barely tell it’s running! I’ve connected my Blueair to the app via phone and it was an easy set-up process. I can 100% control my purifier from my phone. It makes checking the filter replacements and the overall operation of the purifier painless. Additionally, it’s customizable! You can change the fabric pre-filter to another desired look to fit your decor. My room had never felt fresher. I’m so happy with this product and I highly recommend to anyone looking for a new air purifier to add to their space! 10/10 recommend!
