Seems to work well and is quiet and seems efficient. We are using in our open floor plan 1,500 sq foot condo.
I would recommend this to a friend!

Ok...not great

For this price it should be better. 2.4 on the Wi-Fi does interfere with the 5 on my Wi-Fi.No clear process to turn the Wi-Fi off. Quite a bit of searching on the Internet to get it to turn off but it didn't resolve the problem. Only turning off the unit completely resolves the 2.4 issue, but then I have no Wi-Fi.This should be changed to 5.Pure air is what we're looking for but we're also looking to keep down the dust in our rooms. If you keep the air purifier on automatic, it will only kick up to a higher level. When it sees a pollutant regular dust caused by people walking in and out or running a vacuum or sweeping, the floor will not trigger the automatic setting to go higher and remove the dust from the room that has to be done manually.

I have been using standalone air filtration in my home for 15years+. The prior system that I have is a 7-stage filtration system which has but great thus far.BUT! I can surely tell a difference with the Blue Signature system. I wanted something that looked more modern so I went with BlueAir. I left it running for 1-day on level 3 while at work and when I got back home... WOW what a difference in air quality. Air is crisp and sharp. Hard to describe with words....It's been running for almost 1-month now and yes I can tell a difference. Nice design and great filtration. Thank you BlueAir.

An improved control panel

We got this Small Nordic Fog unit for a bedroom, and it seems to be working just fine. I was a bit surprised when the controls lit up every time I (or our dog) neared the unit, unlike the 311i unit we have in our great room.

Awesome Purifier
on June 26, 2026
Posted by: HOWARD K.

Of all the air purifiers I have tried Blueair is the very BEST. They operate exactly as described, super quite, except when they detect pollutants and then go into overdrive, which is exactly the way it should be. The automatic mode is perfect, set it and forget it. I have 3 Blue Signatures small, medium and large. I have definetly noticed the difference in the house since having them. Easy to setup and pair with my Wi-Fi.
