This Pentek CBR2-10 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 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 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.
