It combines sediment filtration and chlorine taste and odor reduction in one, fitting all standard 20-inch Big Blue housings. With a nominal 10 micron rating and a low 1 psi pressure drop at 10 gpm, it supports both municipal and well water systems, delivering up to 1,000 gallons of cleaner, better-tasting water. ## Description The Pentair Pentek NCP-20BB is a 20-inch non-cellulose, carbon-impregnated pleated cartridge that does two jobs in one: it reduces sediment and it reduces taste, odor and chlorine taste and odor, for cleaner, better-tasting water without running two separate filters.Because the media is a carbon-impregnated non-cellulose polyester, the NCP-20BB works with both municipal and non-chlorinated supplies, unlike cellulose cartridges limited to chlorinated water. Its pleated construction adds surface area for high dirt-holding capacity while keeping pressure drop low at just 1 psi at 10 gpm, making it a strong polishing filter for post-RO and well water.Measuring 20" x 4.5" with a nominal 10 micron rating, it fits all 20-inch Big Blue and other heavy-duty housings and replaces any 20" x 4.5" carbon cartridge. Rated to 125Β°F, it provides about 1,000 gallons of chlorine taste and odor reduction at 4 gpm. Replace when you notice a drop in water pressure or water quality. ## Features - DUAL-PURPOSE FILTRATION - Reduces sediment and chlorine taste and odor in a single cartridge, giving you cleaner, better-tasting water without stacking two separate filters. - WORKS ON WELL OR CITY WATER - Non-cellulose carbon-impregnated media is suitable for both municipal and non-chlorinated supplies, unlike cellulose cartridges that are limited to chlorinated water. - PLEATED FOR HIGH DIRT LOADING - The pleated polyester media adds surface area for high dirt-holding capacity at a low pressure drop of just 1 psi at 10 gpm, for extended service life. - 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. Ideal for post-reverse-osmosis polishing and well water. - NOMINAL 10 MICRON RATING - Rated at a nominal 10 micron with about 1,000 gallons of chlorine taste and odor reduction at 4 gpm.
