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.

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.

OPTIONS

Standard Wide-spectrum Filter  with 5-micron sediment filtration

OR
Standard Wide-spectrum Filter with filtration of cysts and microfibers included.  (1 micron absolute sediment filter)

Wide-spectrum cartridge with the addition of microfiber and cyst filtration is the same cartridge plus additional filtration of finer materials including small microfibers and cysts.  This option uses 1 micron absolute filtration.

This optional replacement filter cartridge filters water to 1 micron. This is fine enough to remove cysts.  This is an alternative to the KR-101N Standard wide-spectrum cartridge. This one-micron filter will remove particles 1 micron and larger with 99.99% removal. A micron is 1/1000th of a millimeter.
