Key Features

REDUCES FINE SEDIMENT - String-wound polypropylene cartridge reduces dirt, sand, silt, rust and other fine sediment down to 1 micron to help protect plumbing, appliances and downstream filters in whole house systems.

PRECISION STRING-WOUND DESIGN - A precise winding pattern gives the cartridge greater surface area for high dirt-holding capacity, sustaining flow with a low pressure drop of less than 6 psi at 30 gpm.

PURE POLYPROPYLENE MEDIA - Made from fibrous polypropylene fiber cord that is chemical-resistant and rated for water temperatures from 40 to 165 degrees F for demanding hot and cold applications.

FITS 20-INCH BIG BLUE HOUSINGS - Maximum dimensions 4.5" x 20-1/2" (114 mm x 521 mm) fit standard 20-inch Big Blue housings; measure your housing depth, as the cartridge runs a full 20-1/2 inches long.

MUNICIPAL AND WELL WATER - Suitable for a wide range of sediment applications on both municipal and well water; replace every 6 months or when you notice a drop in water pressure or flow.
