The dual-hose design and 14,000 BTU capacity make it a heavy hitter for spaces up to 500 square feet. I was particularly impressed by the auto-drain technology, which recycles moisture to boost cooling efficiency, and the massive 71-pint daily dehumidification capacity.

Because it utilizes variable-speed inverter technology, it manages to be twice as fast at cooling while consuming significantly less electricity than standard models.
