How much does the AprilAire E050-W cost to run?

About $2.04 a day, or $61.17 for 30 days, running nonstop at DOE's test conditions (less on days it cycles off at its humidity setting).

42 pints/day is 19.87 liters. At an IEF of 1.77 L/kWh that takes 11.23 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 11¢.

How does the AprilAire E050-W rank in its DOE class?

In its DOE class (whole home dehumidifiers), 10 models have a matched Amazon listing. 9 of them have a higher IEF than its 1.77, which is 20% below their median of 2.22. On cost, removing the same 42 pints a day at their median IEF would cost $48.77 for 30 days running nonstop, $12.40 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. This one files exactly that minimum. 2 of the 30 in the class file exactly the minimum. Source: 10 CFR 430.32(v)(2).

Questions

How many pints a day does the AprilAire E050-W really remove?
42 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 AprilAire E050-W cost to run for 24 hours?
About $2.04 for 24 hours nonstop at DOE's test conditions: 11.23 kWh at 18.16¢/kWh, the US residential average for August 2026 (EIA).
