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. :)

    sent to the wrong address, never received

    I put in a change of address long ago and you sent the filter to the wrong location and that's the house that I left due to the mold infestation that made me very ill so please figure it out. Resend it to the address that I put on record and we should be good.
