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!
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.
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!
It was surprisingly easy to change the filter the first time thanks to the clear description in the instruction manual that came with the air purifier.
I received my new filter and want to comment on how easy it was to install. Having my phone pared to the device is so helpful in daily use and maintenance. It’s very guilt as well.
... rarely do you hear the Blueair air purifier, but I certainly know when it is turned off. I have asthma that is now diagnosed as COPD. Without this unit on, I wake up during the night unable to breathe. Blueair has changed my life.
