A portable, potable-water generator for producing high-purity liquid water by condensation of dew from ambient air is described. The generator employs filtration subsystems to remove particulates and aerosols from the incoming air. An enclosed heat absorber cools the filtered air below its dew point and collects droplets of condensate into a closed system. The collected liquid dew is further continually treated in a bacteriostat loop to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. All the subsystems are failsafe-interlocked to disable the generator immediately and prevent delivery of water if any one of them stops functioning within predetermined safe limits. Hybrid embodiments of the water generator attached to or integrated with refrigeration-type appliances such as water coolers, refrigerators, freezers, icemakers and air-conditioners are illustrated.

[ I claim:] [1.] A portable, potable water recovery and dispensing system comprising:a. a portable housing having an air inlet port and an air exhaust port,b. a system for circulating air from the air inlet port to the air exhaust port,c. at least one air filter adapted to remove and trap particulates having a diameter larger than 1-10 micrometers dispersed in ambient air, said particle-generating device sealingly connected upstream of said at least one air filter,d. said air exhaust port being adapted to mount an optional charged-particle generator inside said housing whereby a physiologically-safe level of charged particles and ions is added to the air being discharged,e. said system for circulating air further comprising an internal, ducted, air-circulation device of controllable, variable flow volume sealingly connected downstream of the at least one air filter for causing variable flow intake of ambient air,f. a water condenser within the housing comprising an enclosed cooler having dew-forming surfaces sealingly connected to a heat absorber to receive particle-free air from said system for circulating air, said dew-forming surfaces being adapted to cool boundary-layer air adjacent to said dew-forming surfaces to a temperature in the range of 1-10 deg. C below the equilibrium dew-point of the inlet air stream, thereby forming liquid water on said dew-forming surfaces, said dew-forming surfaces being formed and positioned for gravity flow of said liquid water into an enclosed dripoff water collection vessel,g. a first enclosed water reservoir formed of material appropriate for storage of high-purity drinking water, said first enclosed reservoir being sealingly connected to said enclosed dripoff water collection vessel and fitted with an outlet connection whereby at least most of the water held within said first enclosed water reservoir can be withdrawn,h. a bacteriostatic loop sealingly connected to said first enclosed water reservoir and comprising a closed-loop, re-circulation channel and pump assembly by which water in said first enclosed water reservoir is pumped at a predetermined flow rate through an activated-carbon porous filter-absorber connection in series with a UV treatment zone where the water is continually exposed to radiation of sufficient energy and appropriate wavelength to kill bacteria and viruses,i. a delivery channel sealingly connected to said first enclosed water reservoir and extending through said housing for external dispensing of purified water from said first enclosed water reservoir,j. a monitor disposed within the housing for monitoring housing integrity and proper operation of system components therein andk. further wherein the air inlet port and the air outlet port are both covered by insect-proof screens and all seams and openings of the housing are fitted with barriers and seals to repel and prevent entry of insects and airborne contaminants.
