Description

FIG. 1 is a perspective view of a portable air treatment device showing my new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a front elevational view thereof, the rear elevational view being identical; and

FIG. 4 is a right side elevational view thereof, the left side elevational view being identical; and,

FIG. 5 is a perspective view of a portable air treatment device showing a second embodiment of my new design. The sole difference from the first embodiment resides in the appearance of the water bottles.

The bottom view of the portable air treatment device is not part of the design sought to be patented and is therefore not shown.
