Echo Cleaning Cartridge

Echo Cleaning Cartridge is a small, one-time-use cartridge that releases cleansing citric acid throughout the Echo Water Machine. Designed to fit in the same filter housing, it is approximately the same size as a replacement filter for the Echo 9, 9 Ultra, and H2. The accumulation, flavor, and undesired particles are eliminated by the citric acid. Through cleaning, it allows citric acid to be released into the Echo water machine. Keep the user's hydrogen water crisp and clean.
