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. :)

    Quick and easy filter replacement.

    The filter replacements slipped in like a breeze. Always amazed me how much dust is picked up in the prefers that I’ve been vacuuming out monthly.

    Terrible product

    Every mobile app update disconnects the device for weeks for being able to manged. Been happening for years. Interns runs the IT department and don't test any production pushes.

    Unit Won't Reconize New Filter

    I've tried everything suggested from your website, but I can't get the Protect 7400 to recognize the new air filter. In spite of these efforts, the unit still shows the filter at 0%.
