A portable, toilet ventilating, air-filtering device for boats, house trailers, motels and the like, in which the housing interior is divided into opposite pressure-equalizing plenums by transverse partitioning filter means, and in one of these plenums is mounted a rotatively and vertically adjustable intake duct with spatulate nozzle head that can serve as a carrying handle when nested retracted against the housing top. A suction-blower mounted in communication with the opposed plenum draws air from the toilet bowl and through filter panels for discharge through a bottom opening into a discharge duct recessed in the bottom exterior.
