A system for cleaning air wherein the air to be cleaned is bubbled up through an aqueous phase and an organic phase. The air is bubbled upwardly through the liquid to take advantage of the weight of the liquid to compress the gas, thereby increasing the solubility of the gas in the liquid. Because of specific gravity, the aqueous phase is generally at the bottom of at least one cylinder or container, and the organic phase is generally on top of the aqueous phase. Gases are removed either continuously or periodically to ensure that there are adequate reagents in the aqueous and organic phases, so that the reagents therein can be replaced as needed. There is no limit to the number of cylinders that can be used, depending upon the impurity and thus the amount of reagents to be used in treating the air.

What is claimed is: 1. A method for removing undesired gases and microorganisms from air comprising introducing air into the bottom of at least one container while producing micro bubbles of the air in a liquid; wherein the at least one container holds an aqueous phase and an organic phase wherein air is at the top of the at least one container; the aqueous phase contains compounds to remove or destroy undesired gases and microorganisms from the air which are hydrophilic in character, and the organic phase contains compounds to remove or destroy undesired gases and microorganisms which are lipophilic in character. 2. The method according to claim 1, wherein the containers are maintained at a temperature slightly above the freezing point of the liquids in the container. 3. The method according to claim 1 wherein the air is passed through at least two containers. 4. The method according to claim 1 wherein the aqueous phase contains a compound selected from the group consisting of hydrogen peroxide, potassium permanganate, sulfuric acid, sodium nitrite, sodium hypochiorite, and chlorine dioxide. 5. The method according to claim 1 wherein the organic phase contains a compound selected from the group consisting of free fatty acids and magnesium mono-perhydrate. 6. The method according to claim 1 wherein the air at the top of each container is assayed for purity and, if the air is pure, a switch is operated to convey the air out of the container. 7. An apparatus for cleaning air comprising: a. at least one container, each of said at least one container including an aqueous phase and an organic phase; b. an inlet at the bottom of the container for introducing air to be cleaned; c. means at the bottom of the container adapted and constructed to produce micro bubbles when air is introduced into the bottom of the container; d. an outlet at the top of the container to discharge clean air. 8. The apparatus according to claim 7 wherein at least two containers are provided, and wherein the at least two containers are connected by a tube leading from an outlet from the top of a first container to an inlet at the bottom of a subsequent container. 9. The apparatus according to claim 7 wherein the apparatus comprises at least two containers and a pipe connecting the at least two containers leads to a sampling device for sampling air for analysis. 10. The apparatus according to claim 7 further comprising a micro switch near the outlet of the container to release air that has been determined to be adequately cleaned. 11. The apparatus according to claim 7 wherein the means to produce microbubbles when air is introduced into the bottom of the container is a disc made of material selected from the group consisting of perforated solid plates and sintered glass plates. 12. The apparatus according to claim 7, further including means for refrigerating the containers.
