Keurig Water Filter Cartridge

Refill cartridges are designed for use with the water filter assembly, an easy-to-use, in-brewer filtration unit in your Keurig K140, K145, K150 and K155 Brewing Systems. To keep your water tasting its best, replace the cartridge every two months, 60 tank refills or when the brewer alerts you. Cartridges are not compatible with B140 or B145 Brewers.
