How much does the WatchDog NXT120WH cost to run?
About $3.84 a day, or $115.22 for 30 days, running nonstop at DOE's test conditions (less on days it cycles off at its humidity setting).
89.84 pints/day is 42.51 liters. At an IEF of 2.01 L/kWh that takes 21.15 kWh a day running nonstop at DOE's test conditions. Electricity at 18.16¢/kWh, the US residential average for August 2026 (EIA Electric Power Monthly, table 5.6.A). Each 1¢/kWh you pay above or below 18.16¢ moves the daily figure by 21¢.
How does the WatchDog NXT120WH rank in its DOE class?
In its DOE class (whole home dehumidifiers), 10 models have a matched Amazon listing. 8 of them have a higher IEF than its 2.01, which is 9% below their median of 2.22. On cost, removing the same 89.84 pints a day at their median IEF would cost $104.32 for 30 days running nonstop, $10.90 less than this one.
DOE's minimum for this class is an IEF of 1.77 L/kWh for units made since June 13, 2019. At 2.01, this one files 14% above that floor. 2 of the 30 in the class file exactly the minimum. Source: 10 CFR 430.32(v)(2).
