*This listing is for 2 filters* The CBR2-10 and CBR2-10R are advanced multimedia cartridges designed to reduce chlorine taste and odor, and other contaminants.CBR2 Series cartridges are manufactured using a patented process, and combine powdered activated carbon (PAC) with a specially designed adsorbent medium for lead and mercury reduction.These cartridges are protected by Endurawrap, a uniquely formulated polyolefin bilaminate prefilter, designed to significantly increase the useful life of the cartridge by trapping sediment that typically plugs carbon block cartridges. The CBR2-10R has a built-in flow restrictor (0.6 gpm) to allow for maximum contact time.Pentek is the largest brand in the filtration industryPentek is the originator of carbon block production technologyPentek is the largest producer of carbon blocks worldwideVOC* Gallons @ GPM600 @ 0.6(2270L @ 2.3 Lpm)MTBE* Gallons @ GPM500 @ 0.6(1890L @ 2.3 Lpm)Cyst Reduction>99.95%Lead & Mercury Reduction2000 Gallons @ 0.6 GPM(7570 @ 3.8 Lpm)* Based on manufacturer's internal testing.ModelMaximum DimensionsNominal µm Rating*Initial ΔP @ Flow*Chlorine Capacity @ Flow*CBR2-109-3/4" × 2-7/8"0.5 µm15.0 psid @ 1.0 GPM>20,000 gal @ 1.0 GPMCBR2-10R9-3/4" × 2-7/8"0.5 µmRestricted to 0.6 GPM>20,000 gal @ 0.6 GPM* Based on manufacturer's internal testing.
