Abstract
A convection-based device having no moving parts, which effectively catalytically removes volatile organic compounds from an ambient airspace. The device has, located within a vented housing, a catalytic structure designed to allow air to pass through it. The catalytic structure is heated by electric current and maintained to a predetermined temperature. Air enters the bottom of the device, passes through the catalytic structure, where the volatile organic compounds in the air are reduced, and exits the top of the device.
