ThermaPureHeat, developed by E-Therm, uses superheated dehumidified air to disinfect, decontaminate and dry out buildings in much the same way heat is used to pasteurize milk and kill bacteria in wine.

Propane-powered portable heaters and air blowers are used to inject superheated air into the affected space, raising the temperature of a single room or space as high as 160 degrees for several hours.
