Review on Ridgid VF4000 Standard Filter for 5 Gallon and Larger Wet/Dry Vacs - Replacement VF4000 Filter, Pack of 1 - Brand New! by Jennifer Miller

When first (attempting) removing the filter from the motor head to clean it of dust and dirt, the filter paper came loose from the rubber end of the housing and the filter became unusable. I didn't even touch the paper. I pushed on the center mounting pin while pulling on the rubber base to dislodge it from the mounting pin. I've done the same process dozens of times with the original filter to clean and reinstall.
