I am not filtering anything that would require the same performance/features as say a medical counterpoint, but I can attest to the fact that this filters indeed work.I've run them singularly and in pairs through a Buchner funnel with a vacuum pump (really just a relabeled aquarium pump lol) with great success. I achieved my desired results which was the removal of fine particulates from Everclear.Be forewarned, even though StonyLab produces these filters and supposedly their Buchner funnels (mine has a stamp indicating the mm of the funnel directly above a sticker that says 'StonyLab 100mm' that is laughably crooked) these 94mm are just slightly too large to rest flat in their 100mm Buchner funnel.TL;DR - They do the job at the perfect price point.
