Absolutely perfect for the price
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.

Great Filter for your lab work!
I use these filters in conjunction with a vacuum beaker and vacuum pump, which speeds the process!

These DO NOT FIT StonyLabs 80mm buchner
The description says 74mm diameter and fit the StonyLab 80mm buchner funnel. The papers are actually 75mm and thus slightly too big to sit flat in the buchner, meaning it will not work properly. You'd think you could trust a business when they say their own products work together. I am buying filter papers from another brand.
