FAQ

Depending on usage, your filter will last up to 9 months.

It’s important to change your filter when needed because dirty filters clean the air less efficiently, reducing the purifier's ability to capture pollutants and affecting overall air quality in your space.

    Perfect air cleaner

    Clark (that’s Blueair cleaner’s name) is doing a fantastic job of cleaning our air and keeping us informed as to how clean our air is. Therefore, replacing its filter is a regular way to keep Clark working great. Replacing the filter was easy and he continues his job as I write. :)

    Terrible app and email performance!!!!

    When you change the filter. For some reason you need to reconnect to the internet via the app. Well that works poorly!! I had to delete the device to be able to connect it. Once connected the app isn’t giving me the reports on the particle counts. Very poor support via the app as well. You can do better I’m sure. All of this has happened twice since purchasing the purifier. Now the requested critique “Agree & Submit” entry isn’t working! Just down graded my rating again!
