Jura Claris Smart+ Filter Cartridge

Jura's Claris Smart+ filter cartridge sits inside the water tank and treats every drop before it reaches the boiler. It absorbs heavy metals and chlorine while keeping the minerals that help espresso taste like espresso, and slows limescale build-up at the base of the tank. Cartridge life depends on how hard your water is — the machine will tell you when to swap it.
