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.
BUBlueair UK7 months agoThank 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

I bought a set for my daughter and her husband and I bought a set for my niece. I own the dust magnet and absolutely love it, and I knew they would love their blue air air purifiers as well.

Happy to have the replacement pre-filter so I can replace and don’have to wait for the other one to wash and dry
