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.

LG LP1419IVSM
