Editor's Notes & Price Research
Per the product page description: Use with Shop-Vac Brand wet/dry vacs 5 gallon and up.

Lowe's currently have Shop Vac filters on sale for $7.84 good thru December 4th. I needed one and when I checked out the lady commented on "these are scanning at a good price," so I ran back and picked up half a dozen more as this beat the best price I've seen them on Amazon (~$10). The ones I have all have the lock feature on the cartridge.
For me personally, I've never tried to reuse them. I use these for heavy cleaning and often cake up the filter and discard.
