Product Description

Pentair Pentek EP-20BB Big Blue Carbon Water Filter, 20-Inch, Whole House Carbon Block Replacement Cartridge with Bonded Powdered Activated Carbon (PAC) Filter, 20" x 4.5", 5

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.

This Pentek EP-20BB carbon block filter cartridge reduces fine sediment and chlorine taste and odor in residential and commercial drinking water. It has a nominal (85%) filtration rating of 5 microns. The filter will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 90% in up to 40,000 gallons at a flow rate of 4 gallons per minute (gpm). This cartridge is made of bonded powdered activated carbon (PAC) filter media wrapped in a polyolefin pre-filter with polyethylene outer netting. The nitrile butadiene rubber (Buna-N) gaskets seal the cartridge against the housing (sold separately). The cartridge has an initial pressure drop of 5.5 pounds per square inch (psi) at a flow rate of 5 gallons per minute (gpm), and operates over a temperature range of 40 to 180 degrees F (4.4 to 82.2 degrees C). This carbon block filter cartridge meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is used for purification of residential and commercial drinking water.

The nominal filtration rating is for a particle removal efficiency of 85%. Chlorine reduction capacity is the minimum total amount of water for which the free available chlorine (FAC) at a concentration of 2 ppm is reduced by at least 90%.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes. They are made of densely packed synthetic or natural fibers that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced. Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.

Pentair manufactures industrial, commercial, and residential water filtration components and systems. The company, founded in 1966 and headquartered in Minneapolis, MN, meets International Organization for Standardization (ISO) standards 9001 and 14001 for quality assurance.
