General Grade Teflon®
General Grade Teflon® Cartridges are designed for multi-purpose use wherever a cost effective Teflon® membrane cartridge is required. These Teflon® membranes are hydrophobic and resists wetting in critical air/vent applications. Priced below special purpose Teflon® filter cartridges, General Grade Teflon® cartridges are still manufactured with the same careful attention to quality and performance.
