Key features
Reduces Whole-House Sediment
Captures dirt, sand, silt, and rust down to 30 microns to help protect your appliances, water heater, and plumbing throughout the home.
16+ Square Feet of Media
More than 16 square feet of pleated polyester fabric maximizes dirt-holding capacity and extends the time between changes; a sonically welded seam reduces internal bypass for cleaner filtration.
Durable and Reusable
Non-woven polyester media is washable and reusable, so you can rinse and reinstall to extend cartridge life; works with both chlorinated city water and non-chlorinated well water.
Fits 20-Inch Big Blue Housings
Measures 20" x 4.5" and fits all 20-inch Pentair Pentek Big Blue and other heavy-duty housings; drops in to replace any 20" x 4.5" sediment cartridge.
Low Pressure Drop
Pleated design keeps flow strong at under 1 psi drop at 20 gpm; rinse and reuse when you notice reduced flow, and replace once the media no longer cleans up.
