HOPSEN: 3 DOE certified models

HOPSEN has 3 dehumidifier basic models certified to DOE as of 2026-11-03, rated 10 to 20 pints/day under the 2019 DOE test. How their efficiency compares with their DOE class is below.

Highest certified water removal among its dehumidifiers: HOPSEN HD20 at 20 pints/day.

#	Model	Labels	Pints/day (2019 test)	IEF, L/kWh	DOE class	Brands
1	HOPSENHD20	IEF 1.3	20pints/day, 2019 DOE test	1.3	up to 25	1

How efficient are HOPSEN dehumidifiers?

Of the 3 HOPSEN dehumidifiers, none files a higher IEF than the class median: 3 fall below it.

HOPSEN dehumidifiers against the median IEF (L/kWh) of their DOE class. DOE data as of 2026-11-03.
DOE class	HOPSEN models	Above median	Class median	Best HOPSEN
Portable dehumidifiers up to 25 pints/day (253)	3	0	IEF 1.7	HD12 IEF 1.3

A higher IEF means more water removed per kWh.

Who makes HOPSEN 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 HOPSEN 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 HOPSEN alone.

How much does a HOPSEN dehumidifier cost to run?

Running nonstop at DOE's test conditions, the 3 HOPSEN dehumidifiers with both figures use 3.64 to 7.28 kWh a day. That's about 66¢ to $1.32 a day, or $19.83 to $39.66 for 30 days. The lowest is HOPSEN HD12 (10 pints/day, IEF 1.3) and the highest HOPSEN HD20 (20 pints/day, IEF 1.3).

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 HOPSEN

Is HOPSEN a good dehumidifier brand?: How its 3 dehumidifiers compare on efficiency with their DOE class is above. All 3 are filed under HOPSEN alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
Does HOPSEN make a 50 pint dehumidifier?: No current DOE record shows one as of 2026-11-03. Its largest, HOPSEN HD20, certifies 20 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 HOPSEN dehumidifier is the most efficient for its size?: HOPSEN HD12, HOPSEN HD12 and HOPSEN HD20 tie at IEF 1.3: tied with 62 others at DOE's 1.30 minimum.
