  • Patent number: 8499489
    Abstract: A method and kit of components for destroying organisms and toxins in from an enclosure such as a building. Temperature sensing probes are installed in the enclosure to indicate structure temperature and a recorder is used to record the temperature of said sensing probes in real time. Hot air is introduced into the enclosure through one or more ducts to raise the structure temperature to at least about 120° F., as monitored by the temperature sensing probes. This is sufficient to kill essentially all insects, bacteria, virus, dust mites, spiders, silver fish, fungi and toxic molds such as aspergillus oryzae, aspergillus terreus, aspergills versicolor, cladosporium hergbarum, stachybotrys chartarum, penicillium aurantiogriseum, pencillium chrsogenum, pencillium glabrum and fusarium oxysporum. and the like. The air can exit through open doors and windows or through ducts to a filter assembly that captures the remains of the organisms. Ozone may be added to the heated air to improve efficiency.

  • Patent number: 8272143
    Abstract: A process for removing or treating harmful biological and organic substances within an enclosure includes heating the ambient air within the enclosed area to a predetermined temperature over time to cause harmful biological or organic substances to be destroyed or migrate into the ambient air. Temperature and pressure levels are monitored through the treatment process. Contaminated objects or areas may be subjected to biocides, irradiation, or even freezing as part of the treatment process. The air removed from the enclosure is preferably passed through an incinerator, a filter or an irradiation device and the heated air is re-circulated to enhance efficiency.

  • Publication number: 20080014111
    Abstract: The present invention relates to methods of sanitizing structures, buildings, passenger occupiable vehicles, and other enclosed or enclosable spaces. More particularly, the present invention relates to a method for killing and/or removing pests and their allergens, bacteria, viruses, fungi, molds, volatile organic compounds and other dangerous substances, from such enclosures.

  • Publication number: 20050220662
    Abstract: A process for removing or treating harmful biological and chemical substances from an enclosure, such as a building or vehicle by using heated air. The method of the present invention is non-toxic and can be performed in a relatively short amount of time while effectively killing and removing a large proportion of dead organisms and substantially reducing volatile organic compounds.

  • Publication number: 20050013727
    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.
