ABSTRACT:
A timed ventilator for toilets which mounts entirely within the toilet tank, and which operates from a battery power source to remove air from the toilet bowl and move the air through a charcoal filter for deodorizing. An external control includes an automatic time delay which will hold the fan on for a desired amount of time necessary to change the air in the small volume of the toilet bowl.
