i would like to use my shop vac to clean my stove after it cools. i tried cleaning it once with the regular filter and it exhales a terrible amount of dust. i mean it was really bad. i was wondering if they sold a filter for this purpose. i have a 6 gallon 3 hp shop vac. i looked into loveless ash vacs and i found they arent cheap. at 250 bucks they are the price of a ton of wood pellets. what do you guys use? i have been using my household vaccum just because the bag doesnt leak nearly as much dirt as the shop vac did, however i realize that is less than ideal.
