The Shop-Vac® Tear Resistant Wet / Dry Filter Bag makes it easy to dispose of dry debris and keeps the tank clean, when it is used for dry pick up. During wet pick up, the bag filters out medium to large debris as the liquid passes through the bag into the vacuum’s tank. This allows you to dispose of the liquid, into a drain, without the worry that debris will clog the drain. The tear resistant material prevents the bag from ripping during filling and disposal, while the sturdy plastic collar keeps the bag attached to the vacuum inlet. This medium filtration level bag, works great for cleaning out fish tanks and picking up household dirt, sand and sawdust. This bag is 20% more efficient than the standard Shop-Vac® brand filter bag. Use the convenient collar cover to keep the dirt in the bag during disposal. This tear resistant wet / dry filter bag fits 5 to 10 U.S. gallon* (18.9-37.8 litre*) wet/dry vacs and comes in packages of two. Non-hazardous, non-toxic, non-flammable materials only.
