Product Details
✓KEEP YOUR WATER CLEANER - Reduces dirt, sand, silt, rust, and other sediment throughout your whole house so cleaner water reaches every tap; the 100% pure polypropylene media will not impart taste, odor, or color.
✓IDEAL HIGH-FLOW PRE-FILTER - Dual-gradient density construction grows denser from the outer wall toward the core, delivering up to 3 times the dirt-holding capacity of similar-size sediment cartridges for longer life between changes.
✓TESTED AND CERTIFIED BY NSF - Manufactured from 100% pure polypropylene and tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements, at a nominal 25 micron rating for coarse sediment.
✓SIZED FOR 20-INCH BIG BLUE HOUSINGS - Drops into any 20" x 4.5" Big Blue or heavy duty whole house housing and replaces most 20-inch sediment cartridges, with a low pressure drop under 1 psi at 20 gpm.
✓REPLACE EVERY 6 MONTHS - Swap the cartridge every 6 months, or sooner when you notice a drop in water pressure or water quality; filter life varies with your incoming water conditions.
