Portable air treatment apparatus

A portable air treatment unit comprising:

• a frame defining at least part of a fluid reservoir;
• a tank on the frame bounding at least part of a volume in which a supply of fluid can be placed;
• a generator on the frame that causes fluid from the supply of fluid to be formed into droplets;
• and
• the portable air treatment unit having an outlet for discharging fluid droplets formed by the generator to within a space within which the portable air treatment unit resides,
• wherein the air treatment unit is configured so that fluid droplets formed by the generator are moved in a controlled path between a first location, at which the fluid droplets are formed by the generator, and the outlet,
• wherein the controlled path is bounded by at least one surface,
• wherein the portable air treatment unit is reconfigurable between:
• (a) a first state wherein at least a portion of the at least one surface can be directly accessed at a second location between the first location and outlet to facilitate cleaning of the at least portion of the at least one surface;
• and (b) a second state wherein direct access to the at least portion of the at least one surface at the second location is blocked.
