How much does the BEHOME PD21MB-20 cost to run?

About 74¢ a day, or $22.30 for 30 days, running nonstop at DOE's test conditions (less on days it cycles off at its humidity setting).

16 pints/day is 7.57 liters. At an IEF of 1.85 L/kWh that takes 4.09 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 4¢.

How does the BEHOME PD21MB-20 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. Its IEF of 1.85 L/kWh is tied for 18th of the 78, and 7% above their median of 1.73. On cost, removing the same 16 pints a day at their median IEF would cost $23.91 for 30 days running nonstop, $1.62 more 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 1.85, this one files 42% 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 BEHOME PD21MB-20 really remove?
16 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 BEHOME PD21MB-20 cost to run for 24 hours?
About 74¢ for 24 hours nonstop at DOE's test conditions: 4.09 kWh at 18.16¢/kWh, the US residential average for August 2026 (EIA).
Who makes the BEHOME PD21MB-20?
DOE's database has no manufacturer field, so the record doesn't say. It does show 2 brands filing one basic model, PD21MB-20: BEHOME and HBN.
Is the BEHOME PD21MB-20 the same as the HBN PD21MB-20?
Yes, by DOE's records. HBN files the same basic model, PD21MB-20, with the same 16 pints/day.
