Two LG dehumidifiers, the barebones LG UD501KOG5 and the pump- and Wi-Fi–equipped LG UD501KOJ5, performed just as well as other 50-pint models in our testing. However, their compressors emitted a persistent mechanical hum that we easily heard over their fans’ white noise. They also have the most difficult passive-drain hose hookup of all the dehumidifiers we’ve tested, requiring you to remove an extremely stiff cap from the body of the machine and then thread an adapter into the tight confines of the bucket compartment.
