I wouldn t use the vacuum without these bags! - I ve used these filter bags since I purchased my Porter Cable 15 Gal. capacity Wet/Dry vac. Sure the vacuum works without the bag, but for plaster, drywall, and demolition dirt/dust, you re going to want it. The bag keeps the vac s main filter from getting clogged up, and when the bag is full, you simply lift it out and throw it away! And they re pretty tough too! I like to milk the most from every bag and even full of plaster dust and debris (heavy) it didn t rip or puncture on the way to the dumpster.Did I mention the non-existent blow-out of dust material? Between the bag s filtration and the vac s filter, the dust gets trapped in the vacuum where it belongs - not floating around your job site.
Filter bag - smilter bag - I have the 10 gallon vacuum. These bags are obviously too big for it. In trying fit the first bag into my vacuum, I either tore the tape binding the end, or it tore on its own. I ve had these bags before and they didn t seem as big. It was the first thing I noticed. I ve also used the Shop Vac brand and generics but think these bags are designed better if they fit. I don t think I ll order them again though. I ll just buy the ones at the home centers.
