    Clean air

    My filter never turns red to indicate the need to change the filter. What’s wrong? Does it take a long time?

    Thanks for the great review of the Blue Pure 311 Auto Series. Nothing is wrong at all. Filters typically need replacing every 9 to 12 months, depending on usage and air quality. In cleaner environments, it can take longer for the indicator to turn red. You can always check filter life in the Blueair app and enable notifications for timely reminders. We appreciate you choosing Blueair and enjoying cleaner air.

    Great product and recommended

    I’ve had the 411 in the bedroom for a couple of years and very sensitive to noise when trying to sleep. No problems with this product as it is whisper quiet.
