    Terrible S&H

    I’m sure this is another one of those companies that’s trying to reduce packaging material and consequently, their environmental footprint. That all sounds well and good.. They sent the filter in its product box, a very thin cardboard material with no taping on any of the seams, just as if someone pulled the box off of a shelf on a retail store and slapped a mailing label on it. The box was all banged up like people have been playing football with it and it caused dents and impressions on the accordion style filter material. Just put the darn thing in a reasonable sized cardboard box,

    shipping it to your customers in a safe, solid and secure manner..

    Thank you for reaching out! Blueair filters are single-use, non-reusable items designed to capture airborne particles and pollutants over their lifespan.

    Most Blueair filter are made from polypropylene plastic and paper, which are recyclable depending on your local municipal waste regulations. Please dispose of or recycle the used filter in accordance with your local waste management guidelines.

    The Signature series is my favorite purifier. It does a wonderful job cleaning the air in my main living space.

    Great and quiet

    Love them. We had the older ones and decided to upgrade - especially with how wild fires are happening all over.
