A pair of old pantyhose saves me aggravation and helps me get the most from my shop vacuum. I cut off enough of one leg to make a pre-filter, tie a knot to close one end, then slip it over the vac’s filter cartridge. This stops all but the finest dust and shavings before they reach the filter. It’s so effective that I have maximum suction until the canister is packed full. One pair of hose is enough to make several pre-filters.
