About This

• KEEP YOUR WATER CLEANER - Reduces fine dirt, sand, silt, rust and other sediment to help protect your appliances, plumbing and downstream filters. Made from 100% pure polypropylene, it will not impart taste, odor or color to your water.
• FINE 1 MICRON PRE-FILTER - Dual-gradient density increases filter density from the outer surface to the core, delivering up to 3X the dirt-holding capacity of similar-size cartridges and 233% greater effective filter depth.
• TESTED AND CERTIFIED TO NSF/ANSI 42 - Independently tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. Manufactured from 100% pure polypropylene for purity and broad chemical compatibility.
• FITS ALL 20-INCH BIG BLUE HOUSINGS - Drops into any 20" Big Blue or other heavy-duty housing and replaces any 20" x 4.5" sediment cartridge, with a low pressure drop under 1 psi at 20 gpm for strong whole-house flow.
• REPLACE EVERY 6 MONTHS - Change the cartridge about every six months, or sooner when you notice a drop in water pressure or water quality. Nominal 1 micron rating is ideal as a fine pre-filter ahead of carbon or reverse osmosis.
