- Reduces fine sediment, chlorine taste and odor, and protozoan cysts in residential and commercial drinking water.
- Nominal filtration rating of 0.5 micron.
- Bonded PAC media with polyolefin wraps and polyethylene netting.
- Initial pressure drop of 3.0 psi at a flow rate of 2 gpm.
- Temperature range of 40 to 180 degrees F (4.4 to 82.2 degrees C).
This Pentek CBC-20 carbon filter cartridge reduces fine sediment, chlorine taste and odor, and protozoan cysts in
residential and commercial drinking water. It has a nominal (85%) filtration rating of 0.5 micron, and 99.95% efficiency
for the reduction of protozoan cysts. It will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at
least 90% in up to 45,000 gallons at a flow rate of 2 gallons per minute (gpm). This cartridge is made of bonded
powdered activated carbon (PAC) filter media wrapped in polyolefin with polyethylene outer netting. The nitrile
butadiene rubber (Buna-N) kets seal the cartridge against the housing (sold separately). The cartridge has an initial
pressure drop of 3.0 pounds per square inch (psi) at a flow rate of 2 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 for
purification of residential and commercial drinking water.

The nominal filtration rating is for a particle removal efficiency of 85%. Protozoan cysts include Giardia, Entamoeba,
Cryptosporidium, and Toxoplasma. Chlorine reduction capacity is the minimum total a 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, s, 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 s, or substances that cause a
change, such as 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 s, the maximum flow rate, and the a 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.
