Abstract
An atmospheric control apparatus for use in a forced air ventilation duct is described having an inlet means to receive air from the inside of said duct attached to a replaceable deodorant cartridge, which is itself attached to outlet means terminating within the duct downstream of the inlet to supply an atmospheric control substance such as an odorant or deodorant into the air stream. Air flow through the cartridge is accomplished by the differential pressures present at the inlet and outlet means in the air duct.
