Abstract: An air purifying device has a housing, a blower assembly disposed within the housing for blowing air, an electrically-charged electrostatic plate, and a thermal layer for heating the air to a temperature of at least 75 degrees Celsius, and preferably at least 180 degrees Celsius. The electrostatic plate is connected to a high voltage power supply providing a voltage of at least 3 kilovolts and preferably at least 30 kilovolts. The blower assembly moves the air through the thermal layer at a volume of at least 0.25 cfm and preferably at a volume of less than 15 cfm.
