An odor control device for use with an air passage of a main heating and/or air conditioning system having a blower. The device has a body with an air flow chamber therein, a panel secured to the body and having an air inlet port for admitting air into the chamber, a rotatable plate mounted on the panel, and a container for odor conditioning material mounted on the rotatable plate and preferably held thereon by a magnetic bar attached to the plate and attracting a perforated metal plate in the container, thereby permitting the container to be easily removed from the plate and attached thereto. The panel and plates have communicating arcuate inlet and outlet passages to permit the air to pass from the chamber in the body to the container and thence to the conduit of the main system. The panel contains a main air intake port for the device, and an opening is provided in the body for communicating directly with the main system conduit, and thermostatically controlled shutters control the intake and last mentioned opening.
