Replacement filters to remove nitrates from drinking water. This cartridge is typically used in rural areas where ground water is contaminated with fertilizers.
NEW IMPROVED Cartridge Casings FOR GREATER DURABILITY.
Cartridge will last approximately 1 year if nitrate level up to 12 ppm.
Can also reduce cyanide by 40 to 70%.
Use this cartridge before a KR-101A or KR-101N in our Dual Housing Unit. The nitrate filter should be first in the water flow, followed by the standard filter.
