Silent, nice to look at, works just as it should

Our unit is over a year old now and we just replaced the main filter. We did have an ultrasonic humidifier in the room (we just moved into this condo in November 2025) which pumped out white dust as the water is so hard in this city. We turned it off and the Blue Air works great. It was working full blast prior to turning off the humidifier. We do love it though and our indoor air quality is always on "blue" now!

The Best

We love both our Blueair Filters. I only have one candle left that's not battery operated. When I light it in the kitchen that is about 30' away from the filter it turns to red. Amazing.

I have recently changed my filter for the second time and expected it to be cleaner than before because I had a very fluffy cat. To my surprise it was absent fur and dander, but still had a lot of dust and particles inside the filter. Great job!

New Filter
on March 2, 2026
Posted by: Paul V. K.

Unit did not indicate we needed a new filter but the air indicator light went from green to a white. Our air quality had aways been green. We followed the instructions with no fix until the manual said "call us". So I decided to first order a new filter. The unit is now back to green.No need to call but really!!!
I would recommend this to a friend!
