Culligan Undersink Drinking Water Filter Cartridge

The Culligan Undersink Drinking Water Filter Cartridge is engineered with a slim design that installs quickly and easily into compatible undersink filtration systems. Constructed with activated carbon-impregnated cellulose media, this cartridge effectively reduces sediment, chlorine taste, and unpleasant odors, providing crisp, clean water for drinking and cooking. Tested and certified by NSF International, this replacement filter delivers reliable filtration performance for up to three months or 250 gallons of use. It serves as a direct replacement for standard-sized undersink housings across major filtration brands.
