## Customer Reviews

### ⭐⭐⭐⭐⭐ Great price, great filters
*by F***R on August 27, 2015*

Great filters!

### ⭐⭐⭐⭐ Pretty good
*by S***T on September 29, 2020*

Good filters. Took a while to get here but overall good product

### ⭐⭐ No labeling anywhere that these are actually 10 micron filters!
*by T***R on May 18, 2016*

There is absolutely no documentation or indication that these are actually 10 micron filters! Even 10 micron filter on a label some where would have saved me the time and effort of viewing these under our microscope for measurement of the gaps. My manager did not like and still doesn't like that there is no where on the packaging that says these are 10 micron filters!
