A portable fan apparatus is provided for ventilating toilet bowls by forced ventilation wherein air from the toilet bowl is exhausted by the fan via a tube that extends through the water trap formed by water in the trap formed partly by the bottom of the toilet bowl and partly by the drain portion of the toilet, thereby exhausting the foul air into the drain line of the building's plumbing system. The apparatus can be carried by a traveler from toilet to toilet, thereby to provide the desired ventilation for any toilet facility the traveler may visit. |
