This is the wide-spectrum replacement filter cartridge filter for canister kitchen filters for all our countertop and undercounter water filters, regardless of the number of canisters.
Replace these filter cartridges once a year.
For a single canister filter or for first in line of a 2 or more canister system, we recommend the KR-101N. For last in line in a 2 or more canister system, we suggest the KR-101A.
The filter cartridge contains copper-zinc and granulated carbon filtering media. Filters chlorine and hundreds of other contaminants. The Wide Spectrum Cartridges have the FOAM ADVANTAGE kdf, pre-washed granulated activated carbon and sediment filtration.
This filter will remove PFOAs. This cartridge does not filter chloramine.
