MilliporeSigma Millipak® Express 20 Filters, Polyethersulfone, 0.22 µm Pore Size, Non-Sterile, 1 Each

Each hydrophobic membrane filter is designed to produce particulate- and bacteria-free water at the point of dispense (POD) for your water purification systems. The filter features a 0.22 μm PES (polyethersulfone) asymmetric membrane, which is heat-sealed in a SAN (styrene acrylonitrile) housing to minimize the release of organic and inorganic extractables. Additionally, the filter is easy to fit and replace.
