Product Details
✓CLEANER, BETTER-TASTING WATER - Reduces bad taste and odor plus chlorine taste and odor across your whole home, using a bonded powdered activated carbon (PAC) block for noticeably fresher water.
✓CARBON BLOCK PLUS PRE-FILTER - A polyolefin bilaminate outer wrap traps sediment to extend cartridge life, while the high-porosity design uses more of the carbon at a low pressure drop of 2.0 psi at 4 gpm.
✓NSF/ANSI 42 CERTIFIED - The EP-20BB is tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements, with a nominal 5 micron rating based on 85% or greater particle removal.
✓FITS ALL 20-INCH BIG BLUE HOUSINGS - Measures 20" x 4.5" and drops into any 20" Big Blue or other heavy-duty housing, replacing any 20" x 4.5" carbon cartridge for whole-house and light commercial use.
✓44,000-GALLON CAPACITY - Rated for more than 44,000 gallons of chlorine taste and odor reduction at 4 gpm and temperatures to 180°F. Replace when you notice returning taste or odor or a drop in flow.
