3M Micro-Klean CS Series Filter Cartridge CS19ZCPN 19 in. 0.5 micron Bleached Cotton Media Polypropylene Core Double Open End 15 per case.

Micro-Klean(TM) CS series filters are an improved conventionally wound cartridge. The materials of construction (core and roving) offer broad chemical compatibility and economical filtration. Continuous length winding eliminates the dead spots found on conventionally wound cartridges. A single roving strand employs a strictly controlled material to produce a consistent and high quality cartridge.
