How much does the WatchDog NXT100cWH cost to run?

About $3.24 a day, or $97.25 for 30 days, running nonstop at DOE's test conditions (less on days it cycles off at its humidity setting).

81.11 pints/day is 38.38 liters. At an IEF of 2.15 L/kWh that takes 17.85 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 18¢.

How does the WatchDog NXT100cWH rank in its DOE class?

In its DOE class (whole home dehumidifiers), 10 models have a matched Amazon listing. 7 of them have a higher IEF than its 2.15, which is 3% below their median of 2.22.

DOE's minimum for this class is an IEF of 1.77 L/kWh for units made since June 13, 2019. At 2.15, this one files 21% above that floor. 2 of the 30 in the class file exactly the minimum. Source: 10 CFR 430.32(v)(2).
