System and process for removing or treating harmful biological and organic substances within an enclosure
DC
First Claim
1. A process for treating a passenger occupiable vehicle or building structure at least partially contaminated with harmful microorganisms or insects or having objects therein contaminated with microorganisms or insects, comprising the steps of:
- substantially enclosing at least a portion of the structure to be treated;
heating ambient air within the structure to a temperature of between 110°
F. to 400°
F. to cause the harmful microorganisms or insects in the structure to be destroyed or migrate into the ambient air;
monitoring the temperature in the structure until the temperature is achieved;
passing the heated air from the structure through a filter;
recirculating the filtered and heated air into the structure; and
directing non-heated ambient air into the structure after a predetermined time of directing heated air into the structure, while continuing to remove the air through the filter.

Abstract
A system and process is provided for removing or treating harmful biologic and organic substances within an enclosure, such as a container, building or vehicle. Air within the enclosure is heated to a predetermined temperature to kill organisms and cause harmful substances in the structure to migrate into the ambient air. Boric acid in combination with the heat may be used to kill mold and similar undesirable organisms. Temperature and pressure levels are monitored. The heated air carrying the harmful substances is passed through a filter to remove the harmful substances, and the heated air is re-circulated to enhance efficiency. The system effectively kills insects, molds, viruses and bacteria and reduces the levels of allergens and volatile organic compounds in the structure.

20. A process for treating a passenger occupiable vehicle or building structure contaminated with microorganisms or insects or having objects therein contaminated with microorganisms or insects, comprising the steps of:
-
substantially enclosing at least a portion of the structure to be treated; introducing heated air of a temperature of between 110°
F. to 400°
F. into the structure to cause the microorganisms in the structure to be destroyed and/or migrate into the ambient air;monitoring the temperature in the structure until the temperature is achieved; aggressively moving air within the structure to aerosolize at least a portion of the microorganisms to facilitate their removal; passing the heated air carrying the microorganisms through a high or ultra-high efficiency particulate arrestance filter; recirculating the filtered and heated air within the structure; and directing non-heated ambient air into the structure after a predetermined time of directing heated air into the structure, while continuing to remove the air through the filter. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
