Pentair CBR2-10R Carbon Filter Cartridge, 0.5 Micron
This Pentek CBR2-10R carbon filter cartridge reduces protozoan cysts, chlorine taste and odor, lead, mercury, methyl tertiary butyl ether (MTBE), volatile organic compounds (VOCs), and fine sediment in residential 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 75% in up to 20,000 gallons at a flow rate of 0.6 gallon per minute (gpm). This cartridge is made of bonded powdered activated carbon (PAC) filter media wrapped in a polyolefin pre-filter. The nitrile butadiene rubber (Buna-N) gaskets seal the cartridge against the housing (sold separately). The cartridge has a flow restrictor to limit the flow rate to 0.6 gpm for sufficient contact time with the filter media, and it operates over a temperature range of 40 to 165 degrees F (4.4 to 74 degrees C). This filter cartridge meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is for purification of residential drinking water in under-sink installations.

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 amount of water for which the free available chlorine (FAC) at a concentration of 2 ppm is reduced by at least 75%.
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.
