Abstract

A portable air treatment apparatus made up of: a) an operating unit for generating fluid droplets to be entrained in air and directed in a stream to an outlet for the operating unit; b) a mask having a body extending around a volume and a surface/edge at an outlet for the volume to be situated near a user's frontal face region, with the mask and operating unit configured so that the mask can be releasably operatively connected to the operating unit whereby the stream of air with entrained fluid droplets flows through the mask body inlet and into the mask body volume; and c) at least one additive component. The mask and at least one additive component, when in an operative position, are movable as a unit relative to the operating unit as the mask is separated from the operating unit.
