Review on StonyLab Cellulose Retention Filter for Precise Quantitative Filtration by Tony Wylie
Good filter but in bad condition
As for the filter properties, they work well. The problem with my item was that it was packaged in a sealed plastic bag but eventually got wet. They were dry, but about half of the filters were warped and not flat, which meant I had to wet them, place them between something very flat, and let them dry completely to flatten them out again. I needed them so didn't have time to send them back for a replacement. Don't know if anyone else has had this problem.
