ABSTRACT:
This invention is a filter assembly to be installed in passenger motor vehicles for the protection of the occupants from pollution originating from either exterior the vehicle and/or interior the vehicle. The assembly is preferably installed in the plenum of the vent which is connected to the cowl plenum chamber of the vehicle's heating-cooling system. The assembly is also preferably equipped with a sensor switch that notifies the drive whenever the filter becomes dirty and must be replaced. The assembly includes a hot fluid heater, such as a hot water heater, which protects the filter from freezing and keeps the filter dry. The assembly prevents pollutants, which are emitted from the exhaust fumes of motor vehicles, as well as odors, hydrocarbons, smoke, soot, dust and allergens-pollen from polluting the motor vehicle interior. By installing the filter assembly in motor vehicles, we can be assured of breathing purer air.
