Made of heavy duty, ultra strong paper that stands up to wear and tear, these filter bags are compatible with the Porter-Cable® 7814 15 gal wet/dry vacuum. The 2-ply design guards against rips, while its ability to hold up to 15 gal means less bag changes. Another plus is that these bags can be immediately sealed as soon as you remove it from the vacuum, helping to prevent spills or messes and making clean-up a snap.
