36 EnviroCare Buster B Allergy Vacuum Bags for Canister Vacuums - Fits PKBB12DW, MCV-160 & BB-1000-DB Models - Dust & Allergen Protection for Home Cleaning - Perfect for Pet Hair, Dust Mites & Allergy Sufferers

I think the double wall Oreck brand bags might perform better, but I use the vac only occasionally in my shop and don't care. I bought enough bags to last until I die for not a lot of money. Works for me. The remaining bags will make someone happy at my estate auction.
