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.

First time at the helm and not a decent explanation on what, how, when & where?

I use these filters in conjunction with a vacuum beaker and vacuum pump, which speeds the process!

I find it very strange that these StonyLab filters don't actually fit a StonyLab funnel. I purchased a 100mm StonyLab Buchner funnel, and these 94mm StonyLab filters papers thinking they would be the perfect match considering they're from the same company. The filters are too large and rise up the sides of their own funnel slightly, instead of sitting down in it. How are you supposed to filter out contaminants if they're sneaking their way past the edge of the filter because it doesn't sit correctly?

As far as the filter capabilities these work well. The problem with my item was it came in a sealed plastic bag yet it appeared to have gotten moist at one time. They were dry but about half of the filters were sort of warped and not flat which meant I had to get them wet and place them between something very flat and let them completely dry to get them flat again. I needed them so I had no time to send them back for replacement. Not sure if anyone else has had that problem.

Non riesco a capire come si possano fare recensioni positive su questo prodotto, in termini di filtraggio di nano particelle. E' semplicemente logico che le spugnette sintetiche che fanno da filtro, semplicemente per la loro tramatura NON SONO IN GRADO di fermare particelle della misura di micron e quindi TOTALMENTE INUTILI PER I POLLINI.L'uso più consono è quello di dilatatore nasale.
