Review on Wunderbag Universal High Capacity Pre-Filters for Wet Dry Vacuums, 2 Pack - Maximize Cleaning Efficiency and Extend Vacuum Life! by Nicole Green

I was demoing bricks and mortar and used it in my Ridgid shop to suck up all the bits of mortar and brick. He did a great job picking up the dust from the solution as I progress. It is very heavy and can carry a lot of weight in a bag. I highly recommend these bags. Only beef is the price. I wish they were about half what I paid.
