This Pentek CBR2-10 carbon block 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 1 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 operates over a temperature range of 40 to 165 degrees F (4.4 to 74 degrees C). This CBR2-10 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 drinking water in under-sink installations.
