Used my six gallon shop vac yesterday. The old one, with the metal canister. Decided to empty it.
Well, the rubber band that holds the paper filter is no where to be found. Filter is, of course, laying in the bottom of the canister.
I have a couple spare filters. I remember they came with spare rubber band, but that replacement rubber band is no where to be found.
Today I was in Dollar Tree, and they had "childrens head bands" in various bright colors. Eight for a buck. Sure, worth a try. And wonders, they are the right size. I used four of them on my shop vac filter, and put four on the shelf with the empty bags.
