1. A method for removing harmful biological and organic substances from an enclosure, comprising the steps of:
- creating a negative pressure within the enclosure;
heating ambient air within the enclosure to a predetermined temperature of between 110°
F. and 400°
F. to cause the harmful substances in the enclosure to be destroyed or migrate into the ambient air;
monitoring the temperature in the enclosure until the predetermined temperature is achieved;
monitoring pressure levels within the enclosure to verify adequate negative pressure; and
removing the heated air carrying the harmful substances from the enclosure 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.

15. A method for removing harmful biological and organic substances from an enclosed structure, 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;
creating 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 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 biological 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.

19. A method for removing harmful biological and organic substances from an enclosed structure, comprising the steps of:
-
physically cleaning a contaminated portion of the structure;
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;
protecting heat-sensitive articles within the structure;
creating 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 substances in the structure to be destroyed or migrate into the ambient air;
introducing a biocide into the heated 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 biological 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.
