  • Water filter

    “The LELIT water softener filters are composed of sodium-based cationic resins. These filters placed inside the tank filter the water and capture the calcium and magnesium salts which would normally precipitate and form scale deposits in the espresso machine circuit. Once captured, these salts liberate sodium salts.”
