How to choose
BTU standards matter
BTU numbers come with a standard: ASHRAE and DOE/SACC measure the same cooling output under different conditions, so compare numbers with the same standard. The DREO lists 14,000 BTU (ASHRAE) and 10,000 BTU (DOE), while the HUMHOLD and DOMANKI list 16,000 BTU (ASHRAE) and 12,000 BTU (SACC). Match the standard before you compare, since an ASHRAE number and a DOE number for one unit differ.
Coverage and room size
Coverage is the maker's own figure: the DREO lists 200 sq ft and the DOMANKI lists up to 850 sq ft. Match the figure to your room size before you buy, since a unit rated for a small room and a unit rated for a large room serve different spaces. Room size, window kit fit and hose length all shape how a portable unit performs in place.
Hoses, controls and drainage
Dual hoses bring in outside air and exhaust heat for balanced circulation on the HUMHOLD and DOMANKI. For controls, the DREO adds app and voice control, while the HUMHOLD and DOMANKI use remote controls. For drainage, the DREO evaporates excess water automatically, and the HUMHOLD self-evaporates water for daily use.
