How much does the Moiswell Defender M145 cost to run?

About $2.12 a day, or $63.59 for 30 days, running nonstop at DOE's test conditions (less on days it cycles off at its humidity setting).

49.83 pints/day is 23.58 liters. At an IEF of 2.02 L/kWh that takes 11.67 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 12¢.

How does the Moiswell Defender M145 rank in its DOE class?

In its DOE class (portable dehumidifiers, 25 to 50 pints/day), 73 models have a matched Amazon listing. Its IEF of 2.02 L/kWh is tied for 7th of the 73, and level with their median of 2.01.

DOE's minimum for this class is an IEF of 1.60 L/kWh for units made since June 13, 2019. At 2.02, this one files 26% 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 Moiswell Defender M145 really remove?
49.83 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 Moiswell Defender M145 cost to run for 24 hours?
About $2.12 for 24 hours nonstop at DOE's test conditions: 11.67 kWh at 18.16¢/kWh, the US residential average for August 2026 (EIA).
