It is molded from bonded powdered activated carbon (PAC) and rated at a nominal 5 microns, so it also captures fine sediment.A high-porosity design keeps water moving through the block as the carbon works, so more of the carbon is used before the cartridge plugs, all at low pressure drop. A polyolefin outer wrap acts as a pre-filter, trapping sediment that would otherwise plug a carbon block and extending the cartridge's useful life.Measuring 20" x 4.5", it fits all 20-inch Pentair Pentek Big Blue and other heavy-duty housings and is tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. Each cartridge provides up to 44,000 gallons at a low 2 psi drop at 4 gpm and handles water up to 180Β°F. Ships as a value 4-pack; replace about every 12 months. ## Features - CLEANER, BETTER-TASTING WATER - Bonded powdered activated carbon block reduces chlorine taste and odor along with other unwanted tastes and odors, giving your whole home fresher water from a single 20-inch cartridge. - HIGH-POROSITY, HIGH-CAPACITY DESIGN - The high-porosity carbon block keeps flowing as it works, so more of the carbon is used before the cartridge plugs; a polyolefin outer wrap traps sediment to extend cartridge life. - TESTED AND CERTIFIED - The EP-20BB is tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements; the nominal 5-micron block captures fine sediment while reducing taste and odor. - 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" carbon block cartridge. - 44,000-GALLON CAPACITY, 4-PACK - Each cartridge delivers up to 44,000 gallons at a low 2 psi drop at 4 gpm; this value 4-pack keeps a year and more of replacements on hand.
