A toilet odor exhaust device for a toilet having a toilet bowl with a rim portion and a hinged seat. The device comprises an air intake nozzle and a vacuum filtering unit. A conduit connects the air intake nozzle to the vacuum filtering unit. A structure is for removably attaching the vacuum filtering unit to the rim portion of the toilet bowl, so that the air intake nozzle will fit between the rim portion of the toilet bowl and the seat. A mechanism is for activating the vacuum filtering unit, when a person sits upon the seat on the toilet bowl. Foul air in the toilet bowl will be sucked through the air intake nozzle, the conduit and into the vacuum filtering unit, in which clean air will exit from the vacuum filtering unit.
