Review on High-Quality HPB2H HEPA Style Bag (Qty. 3) for AstroVac, Valet, and VacuMaid - Ideal for Home & Tools, Model: HPB2HPK by Karina Miller

These bags work so well that the air out is actually cleaner than the air in. I know they aren't cheap but they seem to work great. And a sticker that flips the inlet to seal it after it's full is a great addition. I was amazed at how thick the packs were. These aren't just paper bags.
