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. Replace about every 12 months or when taste returns.
