Abstract
An air filter and humidifier is attached to the back of a clothes dryer. Exhaust air is ducted from the clothes dryer exhaust port to the inlet port on the bottom of the filter/humidifier. From there, the exhaust air is directed upwardly through the filter/humidifier. A deflector redirects the exhaust air obliquely downward against the surface of water within a container. The water humidifies and filters the exhaust air. A variable amount of the conditioned air escapes through an adjustable vent lid into the home and the remainder is discharged through the filter/humidifier and ducted outdoors. A hinged or removable lid allows the user to remove the water container to add or replace water.
