Abstract: A split type potable water extractor from ambient air and water dispenser is invented, comprising separate water generating block located outside a water use area and water dispensing block located inside a water use area. The water generator block cycles refrigerant through a condenser and an evaporator to create condensation by heat exchange with ambient air circulated by an intake airflow system. The condensate water is collected and purified in a cascade of bactericidal loop to remove impurities. The purified water is pumped to a dispensing apparatus which can be installed in the home or other area of water use separate from the water generating block. If any one of the functional parts or units of water generator is disabled the water generator immediately stops operating to deliver water to the tank of the dispensing apparatus.
