This is a stainless steel 300 micron mesh filter. It is sized perfectly for dry hopping in a glass carboy. The screen allows hop oils to flow into the beer but keeps the hop material inside. One of the end has a drilled hole so the tube can be hung and retrieve easily.
Cleaning is as easy as removing the filter, removing the plugs, and rinsing.
Using the tube with plastic carboys is not recommended because it may scratch the inside of carboy.
1" x 14" with rubber end plugs.
