Nylon Mesh Filter Fabric 40 Micron Water Strain Net Mesh Fabric, 39.3 x 78.7 inch

I wanted a micro mesh to prevent Moina from getting sucked into my pump during water changes. It also prevents baby shrimp from getting accidentally sucked, too. I cut a piece to fit over the water change pump’s tube opening leaving a few extra inches so I can gather the fabric over and around the tube end, and then secure it all with a rubber band to keep it in place.

I use this material for my worm tower. The material for my purpose allows moisture to pass through but keeps the worms from migrating ,

Great item! We use it to filter small metal chips from our metal CNC. It holds up without tearing yet all the coolant passes through.

Perfect

Excellent for use!

Perfect mess to hold tiny seeds for sprouting.

Not as advertised. I bought the 250 micron and it’s not even close. I it next to stainless 160 micron and it’s way smaller. Should be 53% larger holes.

New, functions great. Used on PCs to keep the dust out
