Nice filter and app
Works great and looks great. Nice app too. I also like that the app isn't necessary but helpful if you want to run a schedule

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.
