About Filters and Particle Sizes

Use these cartridges in a filter housing to reduce contaminants in your water line.

Styles D-E have an O-ring end cap for a tight seal that prevents liquids from moving through the filter housing without passing through the cartridge. They only fit in housings designed for cartridges with O-ring end caps. Style E has a fin that helps to align the cartridge for a secure fit in the housing; it is designed for multi-cartridge housings.

Style F contains phosphate that dissolves slowly in water to prevent the formation of scale and rust particles.

Solid cartridges are constructed from one piece of material for high strength and durability.
