    Poor

    These pre filters are not re useable. I always have to throw mine away as the Velcro never works again and rips away from the material. It's impossible to find where to buy these because you don't make my model anymore.

    Thank you for your feedback. We’re sorry to hear about your experience with the Blue Pure 511 Pre-filter. The Velcro should hold up with regular use, so we’ve reached out to learn more and see how we can help. We also want to let you know that both the Blue Pure 511 and its pre-filters are still available on our website. We appreciate you sharing your experience—it helps us continue to improve.,Blueair,Blueair Team,clientresponse

    Blue Pure Pre-Filters are a Must!

    We have 4 Blue Air products (3 differnt purifiers) in our home and find the prefilters, essential, to help keep each product running longer and cleaner. And, from the Blue Air website, I can order a different color for each product, depending on the season of airborne particles, or just as a needed replacement when for changing/washing.

    I purchased two of the wrong filter as your numbering system is confusing.

    The BEST air purifier in THE WORLD!

    I've always had an air purifier in every room for most of my life. We recently had air quality issues due to dust and dander (despite rigorous cleaning), and none of our purifiers were doing the trick. Because of the way the air flows in our house, everything gets trapped, and ends in my son's corner room, which caused allergies. We have been using this small, Blue Pure 511 in his room for almost two weeks now, and it's AMAZING. Crystal clear air, so pure, so amazing, NO ALLERGIES. We will now be switching all our purifiers to Blue Air! 10/10! What a lifesaver! Thank you!
