Abstract
Provided is a method for reducing the amounts of fungal spores and small airborne particles in an enclosure, where the enclosure has or is in communication with an air handling system. The method comprises the steps of applying vacuum suction to the air handling system and contacting the air handling system with a first antimicrobial agent; applying a cleansing agent to the carpets and upholstery in the enclosure; fogging the enclosure with a second antimicrobial agent; releasing ozone within the enclosure for a period of time and terminating the release of ozone to allow the ozone concentration to return to normal levels; placing a reservoir containing tea tree oil into the air handling system, and initiating operation of an air purifier air in the enclosure, wherein for a period of at least 90 days, the airborne particles in the enclosure are fewer than 1.0 million airborne particles per cubic meter of air; the airborne fungal spores in the enclosure an amount at least 1.1 times below the amount of airborne fungal spores in the air outside the enclosure before performing the method; and, the surface fungal spores in the enclosure are at least 3.0 times below the surface level of …
