Dehumidifier Experiences

We purchased a Honeywell DH70PWKN, manufactured in China by the Taiwanese company New Widetech. The first one failed almost immediately. The replacement is functional, but the sensors are unreliable, humidity is hard to control, and Honeywell refuses support. At present, our actual humidity level is 40%, although the dehumidifier is set at 65%. It cycles every 12 minutes between 50% and 70% according to the console display. Other neighbors have a Keystone KSTAD70C, Honeywell TP70WK, and a Honeywell TP70AWKN. A General Electric ADEL20LYQ1 is in use in one of the townhouses.

If you research consumer-grade dehumidifiers, you will notice that most of them look similar, with similar controls, functionality, specifications, and user manuals, but different plastic boxes. The reason is that most are designed by the same company and use the same components, though manufactured elsewhere, primarily in China. Those buying a dehumidifier should read the recall notice below regarding fire danger as well as the reviews for the various models. The only American-made unit we are aware of is the Aprilaire E070, which has three times the price. We have not tested the Aprilair yet. It is a good idea to buy a dehumidifier with side output vents to prevent dehumdified air from entering the air intake.

Those wishing to install a dehumidifier need a level location, an adequate electrical supply, and a condensate drain. Some models have an internal condensate pump, and most others have a drain that can be used if the dehumidifier is higher than the sewer line opening. Those of us with A/C have a condensate pump like the Diversitek CP-22, and the dehumidifier condensate can be routed into the existing pump.
