How much does the Auseo D4212B cost to run?

About 61¢ a day, or $18.28 for 30 days, running nonstop at DOE's test conditions (less on days it cycles off at its humidity setting).

9.29 pints/day is 4.4 liters. At an IEF of 1.31 L/kWh that takes 3.36 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 3¢.

How does the Auseo D4212B rank in its DOE class?

In its DOE class (portable dehumidifiers up to 25 pints/day), 78 models have a matched Amazon listing, not counting 1 filing flagged as unusual. 59 of them have a higher IEF than its 1.31, which is 24% below their median of 1.73. On cost, removing the same 9.29 pints a day at their median IEF would cost $13.88 for 30 days running nonstop, $4.40 less than this one.

DOE's minimum for this class is an IEF of 1.30 L/kWh for units made since June 13, 2019. At 1.31, this one files 1% above that floor. 63 of the 253 in the class file exactly the minimum. Source: 10 CFR 430.32(v)(2).

Questions

How many pints a day does the Auseo D4212B really remove?
9.29 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 Auseo D4212B cost to run for 24 hours?
About 61¢ for 24 hours nonstop at DOE's test conditions: 3.36 kWh at 18.16¢/kWh, the US residential average for August 2026 (EIA).
Who makes the Auseo D4212B?
DOE's database has no manufacturer field, so the record doesn't say. It does show 11 brands filing one basic model, OL12D-D023B: Auseo, COWSAR, Crzoe and 8 more.
Is the Auseo D4212B the same as the COWSAR D4212B?
Yes, by DOE's records. COWSAR files D4212B under the same basic model, OL12D-D023B, with the same 9.29 pints/day. 9 other brands file it too.
