The disclosed apparatus dispenses volatized air freshener compound into the room air forcibly moving the air through a prefilter and a high efficiency filter utilizing a fan disposed in the space therebetween. A container of volatile air freshener liquid or gel is positioned in a location such that the air drawn through the prefilter will pass across the top of the container. The container is provided with a lid mounted for movement to open and close the container, the lid being connected to and operable by a control such as a timing mechanism to adjustably regulate the amount of volatized air freshener compound which is permitted to escape into the air passing through the air filter, or the container can be kept totally closed and thus inoperative. |

DETAILED DESCRIPTION In accordance with the invention, a process is provided for selectively dispensing volatilized air freshener compound into room air.
This process includes the steps of forcibly moving the air through a prefilter and a high efficiency filter by means of a fan which is disposed in the space between these two filter elements.
A container of volatile air freshener compound is positioned in this space, so that air which is drawn through the prefilter will pass across the container as it is moving to and through the high efficiency filter.
The container has a lid positioned for operative engagement with an adjustable timing mechanism which may be set for selectively opening and closing the lid of the container in a preselected time sequence.
In this way the dispensing of volatile air freshener into the air flowing through the space between the filter elements may be adjusted or it can be discontinued.
The air freshening apparatus of the invention is employed in combination with an air filtering apparatus having a cabinet, a filter media mounted with the cabinet, and a fan forcibly moving the air through the cabinet and the filter media.
The improvement comprises a container of volatile air freshener compound means, such as a receiving frame, for positioning the container in a predetermined location within the interior of the cabinet in the path of the air being forcibly moved through the cabinet by the fan.
A lid is provided for the container, and the lid is mounted, preferably on a mounting yoke, for movement between a first position wherein it covers the container and prevents the escape of volatilized air freshener compound into the air, and a second position wherein it uncovers the container to permit escape of the volatilized air freshener compound into the air.
Control means, preferably in the form of a timing mechanism, is operable from the exterior of the cabinet for selectively moving the container lid between its first and second positions to adjustably regulate the escape of volatile air freshener into the air passing through the apparatus cabinet
