## Customer Reviews

### ⭐⭐⭐⭐⭐ PERFECT FIT
*by J***E on March 24, 2021*

You can never find filters for purchase at sears, Lowes and Ace Hardware. But you can find the substitute that may or may not fit. This one fits perfectly. Buying more to stock in my shelf.

### ⭐⭐⭐⭐⭐ Tight fit, works well
*by V***E on August 10, 2019*

Tight fit. Needs to be pushed in so gasket is in firmly. Screw on cap was missing on my unit so I'm glad this order came with one. It's also a very tight fit and really needs to be worked on. Seems great. Nice quality.

### ⭐⭐⭐⭐⭐ Good purchase
*by A***R on September 5, 2018*

Correct size for my 6 gal shop vac. Came with the plastic retainer to hold the filter on the vacuum, i still had the old retainer so I didn’t need it, but it was nice to see it came with it just in case.
