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.

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!
