Review on 🧼 Reusable Pre Filter Bag for Shop Vacuums - Wet Dry Vac Debris & Dust Collector Bags for VF 4000, VF 5000, DXVC6912, 917816 OEM Filters - Made in USA, Large, Green - 17" Tall, 7.5" Diameter - FilterPal by Tammy Lewis

It was hard to find a "sock" pre-filter that would fit my large Craftsman 9-17816 paper filter. This washable pre-filter has room! It works so well. I also bought a new paper filter to see how clean it stays. So far this "sock filter" is easy to clean. I just smack it with my hand while it's still attached over the trash can in the yard. After a few uses, the paper filter underneath is as clean as the day I replaced it. No matter how dusty the "sock" is, the suction power of the vacuum cleaner has not lost. What a great product! Thanks very much!
