Claim 0:
1. A method of reducing airborne contaminants in air of an indoor space, the method comprising:
positioning an individual, portable photo-catalytic oxidation system proximate a source of contaminants in the indoor space;
activating the individual, portable photo-catalytic oxidation system to recirculate all of the air in the indoor space through the individual, portable photo-catalytic oxidation system in a multi-pass manner at a rate sufficient to perform from approximately 24 to approximately 32 air exchanges per hour of all of the air in the indoor space before distributing the air to another space, wherein the individual, portable photo-catalytic oxidation system is configured to oxidize contaminates in the air,
wherein a ratio of an airflow capacity of the individual, portable photo-catalytic oxidation system to a volumetric size of the indoor space is in a range from 0.4 to approximately 0.5, and
wherein the indoor space is a hospital room, and wherein the positioning of the individual, portable photo-catalytic oxidation system comprises positioning the individual, portable photo-catalytic oxidation system proximate to a head of the patient's hospital bed, between the patient's hospital bed and an outlet duct of a central heating, venting, and air conditioning (HVAC) unit of the hospital room, and between a side of the patient's hospital bed facing an exit/entrance doorway of the hospital room and the exit/entrance doorway of the hospital room.
