ABSTRACT:
A water generating device for obtaining portable water from ambient air inside or outside a structure or dwelling. There is an air filter for filtering the air prior to processing of the air. The air filter may include a one-time sensing element which renders it unusable when removed from the generator. A condenser is provided for extracting water vapor in the air. Between the condenser and the collection point, there is an immediate temporary holding reservoir, or plumbing to this reservoir, which contains an ultraviolet light to kill existing microorganisms, as well as a pump to transport the water through a subsequent water filter, a second exposure to ultraviolet light, and ultimately, at the final discharge point to the internal or external water storage unit there may be another ultraviolet light that creates a sterile outlet from the primary system. The water filter may also include a one-time sensing element which renders it unusable when removed. A switch may be provided for automatically deactivating the device until the nonreusable or cleanable air filter element is replaced or cleaned. A timer or flow meter may be provided for deactivating the device until the water filter element is replaced after a predetermined number of hours or water volume of operation. A sensor may be provided for deactivating the device when the UV light(s) fail to operate.
