How they stack up

LG LP0621WSR

The smallest and most affordable unit here, sized for rooms the larger Midea Duo MAP12S1TBL, LG LP1419IVSM, and Whynter ARC-14S would over-cool. Like the LG LP1419IVSM and Black+Decker BPACT12HWT it is a single-hose design, so it is less efficient than the dual-hose Midea Duo, but its low capacity is well-matched to small spaces.

Midea Duo MAP12S1TBL

The only dual-hose unit among the top picks, which is why it out-efficiencies the single-hose LG LP1419IVSM and LG LP0621WSR. Its inverter makes it quieter than the Whynter ARC-14S and Black+Decker BPACT12HWT. The Whynter ARC-14S is the other dual-hose unit here, but it is heavier, louder, and less efficient than the Midea Duo.
