How much does the WatchDog 600c cost to run?
About $1.58 a day, or $47.28 for 30 days, running nonstop at DOE's test conditions (less on days it cycles off at its humidity setting).
34.48 pints/day is 16.32 liters. At an IEF of 1.88 L/kWh that takes 8.68 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 9¢.
How does the WatchDog 600c rank in its DOE class?
In its DOE class (portable dehumidifiers, 25 to 50 pints/day), 73 models have a matched Amazon listing. 65 of them have a higher IEF than its 1.88, which is 6% below their median of 2.01. On cost, removing the same 34.48 pints a day at their median IEF would cost $44.22 for 30 days running nonstop, $3.06 less than this one.
DOE's minimum for this class is an IEF of 1.60 L/kWh for units made since June 13, 2019. At 1.88, this one files 17% above that floor. 3 of the 296 in the class file exactly the minimum. Source: 10 CFR 430.32(v)(2).

Questions
- How many pints a day does the WatchDog 600c really remove?
- 34.48 pints/day, as certified to DOE under the 2019 test (65°F, 60% humidity). The older test ran at 80°F, so a rating from it reads higher for the same unit: the 2019 test explained.
- How much does the WatchDog 600c cost to run for 24 hours?
- About $1.58 for 24 hours nonstop at DOE's test conditions: 8.68 kWh at 18.16¢/kWh, the US residential average for August 2026 (EIA).
