1. A system for treating air, vapor, and water, said system comprising: a treatment chamber;a condenser located within the treatment chamber;an air inlet for introducing air and vapor into the condenser;an ozone generator for introducing ozone into the condenser to simultaneously ozonate the air, air vapor, and condensed water within the condenser;an air outlet for removing ozonated air immediately ready for human consumption from the condenser;a water outlet for removing ozonated water immediately ready for human consumption from the treatment chamber; anda hydrophilic membrane separating the air inlet and air outlet of the condenser from the water outlet. 2. The system according to claim 1, wherein the ozone generator is located at least partially within the condenser. 3. The system according to claim 2, wherein said ozone generator is of an electrochemical type consisting of a cathode, anode, and an ion exchange membrane spaced between and separating said cathode and said anode, said cathode and said anode capable of being respectively connected to a negative (−) and positive (+) potentials of a voltage source. 4. The system according to claim 3, wherein said cathode develops a reaction expressed as O2+4e−+4H+→2H2O, and wherein said anode develops reactions expressed as:3H2O→O3(g)+6e−+6H+O2+H2O→O3(aq)+2e−+2H+2H2O→O2+4e−+4H+. 5. The system according to claim 4, wherein the ozone generator is located on the hydrophilic membrane in communication with the air inlet and air outlet of the condenser. 6. The system according to claim 5, wherein the ozonated air withdrawn from the air outlet also includes ozonated vapor. 7. The system according to claim 6, wherein said hydrophilic membrane is of a plastic material having a medium grade of about 0.8μ, a thickness of about 0.0052 inches and a bubble point characteristic given in psid, of about 15. 8. A system for treating air, vapor, and water, said system comprising: a treatment chamber;a condenser located within the treatment chamber comprising a plurality of adjacent and interconnected air channels formed in a material of substantially high thermal conductivity and substantially low density, said plurality of air channels arranged over a hydrophilic membrane;an air inlet for introducing air and vapor into the condenser;an ozone generator for introducing ozone into the condenser channels to simultaneously ozonate the air, air vapor, and condensed water within the condenser;an air outlet for withdrawing treated air from the condenser; anda water outlet for withdrawing treated water ready for human consumption from the treatment chamber. 9. The system according to claim 8, wherein said material having said substantially high thermal conductivity and substantially low density is selected from the group consisting of aluminum, magnesium, titanium, metal filled or carbon filled plastics, and high thermal conductivity carbon composites. 10. The system according to claim 9, wherein said air channels are dimensioned to create radial accelerations of the flow therein. 11. The system according to claim 10, wherein said water outlet includes a suction apparatus comprising spring loaded bellows to assisting in the removal of treated water. 12. The system according to claim 11, further comprising a hydrophilic membrane separating the air inlet and air outlet from the water outlet. 13. The system according to claim 12, wherein the ozone generator is located at least partially within said condenser. 14. The system according to claim 13, wherein said ozone generator is of an electrochemical type consisting of a cathode, anode, and an ion exchange membrane spaced between and separating said cathode and said anode, said cathode and said anode capable of being respectively connected to a negative (−) and positive (+) potentials of a voltage source. 15. The system according to claim 14, wherein said cathode develops a reaction expressed as O2+4e−+4H+→2H2O, and wherein said anode develops reactions expressed as:3H2O→O3(g)+6e−+6H+O2+H2O→O3(aq)+2e−+2H+2H2O→O2+4e+4H+. 16. The system according to claim 15, wherein the ozone generator is located on the hydrophilic membrane in communication with the air inlet and air outlet. 17. The system according to claim 16, wherein the treated air withdrawn from the air outlet also includes treated vapor. 18. The system according to claim 17, wherein said hydrophilic membrane is of a plastic material having a medium grade of about 0.8μ, a thickness of about 0.0052 inches and a bubble point characteristic given in psid, of about 15.
