Review on 🔥 PowerSmith PAAC301: Washable Double Layer Vacuum Filter for Heat-Resistant Ash and Dust Removal, 5"x 5"x 2 by Miriam Moore

They filter ash very well and impressively. A warning: claim they are washable, which is true, but don't try to clean them. I soaked my first one in hot water, everything was fine until I brushed the material together to remove the black stain and the material fell apart. I look like I just got carried away with my cleanse. I blow air through them all the time and can just keep at it.
