Replacement filter to remove Arsenic from drinking water.
Cartridge casing has been improved for durability. LOOKS a little DIFFERENT THAN PREVIOUS casings.
Cartridge will last approximately 2000 gallons at 50PPB. In general, we suggest replacing once a year.
Use this cartridge in conjunction with a KR-101A or KR-101N in a Double or Triple Housing Unit. In every case, the KR101 filter should be placed last in line.
