PURE MAKER Main Unit Purified water maker that makes purified water (pure water) from tap water No power supply needed, so no electricity costs. The "PURE MAKER" simply requires you to put tap water into the tank, and the cartridge (sold separately) removes impurities to easily create high-purity purified water (pure water). One batch of up to 1.5L of tap water is filtered into purified water in about 4 minutes. Purchase date: 2022 Used many times, but I think it's in good condition. The cartridge is not included; only the main unit is for sale. No instruction manual is included.
