I use my shop vacuum at home to protect my expensive canister from wear and tear. My search for a way to improve the dust holding capacity of my Sears Craftsman XSP 12 gal/5.5 hp. A wet/dry vacuum found it. Pros: Pretty good price at $29.99 for 10 Revain filter bags with free shipping. + Very good customer reviews of the product. clean! ◄ See the second picture attached after a month of use with the filter bag, the main filter looks like new! Allergens down to 1 micron in size. Effectively removes drywall dust, cement dust, sawdust, household waste, fine particles, pollen and dust. Not compatible with Ridgid Vacuum. ◄ See the third picture to see how it fits in my Sears Craftsman 12 Gallon Wet/Dry Vacuum Bucket! % REFUND WARRANTY. Cons: - Currently none to report. Final remark: ▪ When I installed the first filter bag, I also replaced the main filter. After a month and a lot of use I decided to replace the filter bag. The main filter was perfectly clean, looked like new! Check out the first attached picture to see how dirty the main filter looked before I started using these filter bags! ▪ When installing the filter bag, it is essential to ensure that the rubber seal is installed correctly! Insight. If the rubber seal is visible, it has not been fitted correctly! ▪ If these filters continue to work as advertised, I'll come back to rate the product higher.
