Our Verdict
Whynter Elite ARC-122DS
LG LP0721WSR
The Whynter Elite ARC-122DS is better than the LG LP0721WSR. The Whynter has a greater overall cooling capacity and won't struggle to the same extent in oversized areas. It also runs far more quietly. It's worth noting that the LG's modest capacity does have a bit of an upside, however, in that its compressor is forced to run almost constantly to achieve your desired temperature instead of cycling on and off, so there are no big swings in ambient humidity or temperature levels.
