Air treatment systems and methods

A method of treating air with an air treatment unit, the method comprising:

• flowing air to be treated into an air inlet of a reaction reservoir, wherein the reaction reservoir includes an air treatment solution including a mixture of an oxidizing agent and alkali hydroxide;
• converting at least a portion of the flow of air to be treated into a plurality of microbubbles using an air dispersing element;
• introducing the microbubbles into the air treatment solution, such that an amount of one or more target gas species contained within the plurality of microbubbles is reduced through reaction with one or more constituents of the air treatment solution;
• generating, by a sensor, an output indicative of a pH level of a solution in the reaction reservoir;
• and
• outputting treated air from the reaction reservoir.
