Abstract: The present invention is a self-inflating heat sanitizer, which uses convective heat transfer to eradicate bed bugs within an item. The heater unit propagates and reheats the air within the present invention as the heated air flows through the present invention. The heat chamber enclosure is a compartment that allows the heated air to circulate around the item and raise the temperature of the item to above 140° F. The structure of the heat chamber enclosure is inflatable walls, which are pressurized when the heated air flows into the heat chamber enclosure. The heated air will then vent out of the inflatable walls into the treatment volume, where the item is located. The insulated ducts lead the heated air from the heater unit into the inflatable walls and lead the heated air from the treatment volume back to the heater unit.
