How efficient are Humsure dehumidifiers?

Of the 3 Humsure dehumidifiers, 2 file a higher IEF than the class median and 1 falls below it.

Humsure dehumidifiers against the median IEF (L/kWh) of their DOE class. DOE data as of 2026-11-03.
DOE class	Humsure models	Above median	Class median	Best Humsure

A higher IEF means more water removed per kWh.

Who makes Humsure dehumidifiers?

DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.

None of the 3 Humsure basic models is filed by another brand as of 2026-11-03, and none uses another company's model number. DOE's records tie them to Humsure alone.

How much does a Humsure dehumidifier cost to run?

Running nonstop at DOE's test conditions, the 3 Humsure dehumidifiers with both figures use 2.76 to 4.25 kWh a day. That's about 50¢ to 77¢ a day, or $15.05 to $23.17 for 30 days. The lowest is Humsure FDD12-5094B1V1R5 (8 pints/day, IEF 1.37) and the highest Humsure FDD20-5270ZV1R5-E (16 pints/day, IEF 1.78).

Real use cycles on and off with the humidity, so these are the upper figures for a day of nonstop running.

At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.

Questions about Humsure

Is Humsure a good dehumidifier brand?: How its 3 dehumidifiers compare on efficiency with their DOE class is above. All 3 are filed under Humsure alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
Does Humsure make a 50 pint dehumidifier?: No current DOE record shows one as of 2026-11-03. Its largest, Humsure FDD20-5270ZV1R5-E, certifies 16 pints/day under the 2019 DOE test. Boxes that quote the older 80°F test read higher for the same unit. How the 2019 test changed pint ratings.
Which Humsure dehumidifier is the most efficient for its size?: Humsure FDD20-5270ZV1R5-E and Humsure FDD20-527CZV1R5-E tie at IEF 1.78: higher than 173 of the 253 in its DOE class (portable dehumidifiers up to 25 pints/day). At the other end is Humsure FDD12-5094B1V1R5, at IEF 1.37, higher than 77 of the 253 in its class.
