BleAir 311i Max - Effective, Efficient, Versatile, and Extremely Helpfull For Us Allergy Sufferers
By eNGeeNC on Reviewed in the United States on June 20, 2025
BlueAir air purifier 311i Max has proven to clean air quality indoors fast and very efficiently in the first few weeks we've owned and used the product. In our case, the improvement in air quality with the BleAir 311 Max was great enough to bring two allergy sufferers both immediate and substantial improvement in breathing ease and freedom from allergy symptoms. I can't judge whether everyone will see the same degree of relief, but I am positive we are not the only family to enjoy great relief form BlueAir use. BA 311 replaced a Heneywell large room model and made the prior unit's speed and efficiency seem poor by comparison. The cellphone app for BlueAir is an immensely useful included accessory. You can't see the quality of air indoors, and often can't smell or sense many polutants that effect the way you feel as eall as health. The BlueAir air quality sensors and app's display provide both a quick guide and continuous monitor to how well the air cleaner is operating, to the spped of cleaning needed for your particular hme conditions and assurance that your room air quality is kept the kindest to your health. Reliabilty and durability remain to bee seen in our case, as the purchase was very recent, but BlueAir appears to have a reputation for good quality and reliability. We hope that we and any reader fo this review will enjoy a long and happy relationship with the BlueAir 311i Max Air Purifier.

Mid-level Quality with extra remote control app layered on top.
By Book Lover on Reviewed in the United States on December 3, 2024
I have a BLUEAIR Classic 605 that I have had running for 15 years and it just started squealing sometimes. This unit cost $350 in 2008 and sells now for over $800. This was a top of the line unit with a high quality motor that was very quiet. I bought this unit recently for use in a bedroom. I was disappointed to see (and unfortunately hear) how BLUAIR has greatly reduced the quality of their components to position themselves in the lower cost price point. It is not silent. Even at the lowest fan speed on the night time setting there is still a distinct hum coming from the motor. At higher speeds you get sound from the fan blades moving so much air, but this is very low speed, very little air movement and a lot of hum that indicates a cheap electric motor. It connects to your wi fi and has an app for your phone so you can control it remotely. This is a pretty good app and you can set up time schedules to automatically change settings. The app also lets you change the brightness of the LED display that includes completely off. It has an auto mode that controls the speed based on the concentration of particles it is detecting in the air. Unfortunately, the sleep mode is still too loud for me as the motor hum is at an annoying frequency for me so I just turn it off at night. The night mode doesn't really do much anyway. Also, unfortunate is that when the unit is turned off, the power button LED lights up (and shines brightly on your bedroom ceiling) even if you had set the LED display brightness to off. I have to unplug it for sleeping. Good thing I have it plugged in to a readily accessible outlet -- If it was behind a piece of furniture this would make the unit unusable for me. During the day it does a fine job of cleaning the air in my bedroom. I just wish all the money spent on the remote control features and measurement of particle concentration for 3 different size particles technology was instead spent on a higher quality motor. I do not NEED any of the extra gadgetry and to me, the quality of the motor determines the quality of the whole unit. Overall, it is a decent unit for the price and cleans the air well, so I am happy with it, but I am paying for things I do not need.
