39 x 78 inch Fine Filter Mesh Nylon Fabric Net Material Water Strain Mesh Size 35-250 Micron (250 micron)

This was exactly what I was looking for! I have a few isopod colonies started in aquariums and wanted something to keep them and their babies in, but allow for air flow. This works perfectly. I plan to add plants to these tanks at some point and make them decorative displays, as well as to add to my reptile enclosures clean up crews as needed. But this fine mesh fabric is perfect for what I needed. I found it and purchased based on someone else mentioning they used it with isopods, so hope my review can help someone else.

I expect that this material will hold up for the filtering process for which I intend it for

Setting up for rainwater collection was looking for this and other filtering materials.

Only the trichomes fall through the screen so the keef turns into to hash just by squeezing it in between your fingers

I'm using this as an insect screen and I'm happy to report that the "holes" are so tiny that insects won't be able to get through, not even the small ones, while still allowing air to pass through. (I can't imagine any insect in everyday city life being tiny enough to get through.)They only small negative is that it came with a few strands unraveling. It didn't cause any issues and I simply trimmed off the loose threads, but it does make me wonder if more threads will come off in the future from use.
