Abstract
The present invention provides an air purifying system which both filters and neutralizes odors in the air. A housing includes an inlet, an outlet, and an internal flow path from the inlet to the outlet. The outlet is preferably configured to provide a conical exhaust flow path. Fan means are located within the housing to move air through the housing along the flow path and out of the housing through the outlet. A filter is interposed in and spans the flow path of the housing to filter particulate matter from the air passing through the housing. An odor neutralizing chamber within the housing is partially interposed in the flow path. The chamber contains an odor neutralizing chemical which vaporizes in the presence of air. A mechanism is provided for controlling the amount of odor neutralizing chemical vapor which enters the air flowing through the housing.
