1. A method for destroying and removing harmful biological organisms, including molds and fungi, and chemical substances from an enclosure, comprising the steps of:
- positioning at least one temperature probe at a predetermined location within the structure;
positioning a manometer within the structure to measure the pressure within the structure;
controlling the egress of air from the enclosure with respect to the ingress of air into the enclosure to create a negative pressure within the structure;
directing heated air into the structure and distributing the heated air until an interior of the structure rises to a predetermined temperature of between 110°
F. and 400°
F. to cause the harmful biological or chemical substances in the structure to be destroyed or migrate into the ambient air;
introducing moisture into the heated air to increase the humidity of the air;
monitoring the temperature of the structure until the predetermined temperature is achieved;
monitoring pressure levels within the structure to verify adequate negative pressure;
aggressively moving the air within the structure; and
removing the heated air from the structure through a filter.

Abstract
A system and method for removing harmful biological and organic substances from an enclosure, vehicle or container includes protecting heat-sensitive articles within the enclosure. A plurality of temperature probes are positioned at predetermined locations within the enclosure. The air within the structure is heated to a predetermined temperature up to 400° F. to kill organisms and cause harmful substances in the enclosure to migrate into the ambient air. A negative pressure is created in the enclosure and the heated air carrying the harmful substances passed through a filter and is then vented from the enclosure and passed through a filter to remove the harmful substances from the heated air. The system effectively kills, molds, viruses and bacteria and reduces the levels of allergens and volatile organic compounds in the enclosure.

12. A method for destroying and removing harmful microbiological, including molds and fungi, and chemical substances from an enclosure, comprising the steps of:
-
positioning a plurality of temperature probes at predetermined locations within the structure;
positioning a manometer within the structure to measure the pressure within the structure;
controlling the egress of air from the enclosure with respect to the ingress of air into the enclosure to create a negative pressure within the structure;
directing humidified heated air into the structure and distributing the heated air until an interior of the structure rises to a predetermined temperature of between 110°
F. and 400°
F. to cause the harmful microbiological or chemical substances in the structure to be destroyed or migrate into the ambient air;
monitoring the temperature of the structure until the predetermined temperature is achieved;
monitoring pressure levels within the structure to verify adequate negative pressure;
aggressively moving the air within the structure to aerosolize the microbiological and organic substances;
removing the heated air carrying the harmful substances from the structure through a filter;
after a predetermined period of time, directing non-heated air into the structure; and
removing the non-heated air from the structure through the filter. - View Dependent Claims (13, 14, 15)
