PTFE filter Features and Benefits: Cobetter LPF filter cartridges, manufactured with permanently hydrophobic PTFE membranes, provide the cleanest fluids at the highest flow rate with the lowest possible cost. Cobetter LPF serves as a low-cost alternative to all fluoropolymer cartridges in aggressive applications and maintains broad chemical compatibility with low extractable levels and high particle retention rates.
