Our Verdict

LG LP0721WSR

Whynter Elite ARC-122DS

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: its compressor is forced to run almost constantly to achieve your desired temperature, rather than cycling on and off, so there are no big swings in ambient humidity or temperature.
