How efficient are FRIEDRICH dehumidifiers?

Of the 4 FRIEDRICH dehumidifiers, none files a higher IEF than the class median: 4 fall below it.

A higher IEF means more water removed per kWh.

Who makes FRIEDRICH 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 4 FRIEDRICH 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 FRIEDRICH alone.

How much does a FRIEDRICH dehumidifier cost to run?

Running nonstop at DOE's test conditions, the 4 FRIEDRICH dehumidifiers with both figures use 8.72 to 13.14 kWh a day. That's about $1.58 to $2.39 a day, or $47.49 to $71.61 for 30 days. The lowest is FRIEDRICH D35B1B (35 pints/day, IEF 1.9) and the highest FRIEDRICH D50B1B (50 pints/day, IEF 1.8).

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

Questions about FRIEDRICH

Is FRIEDRICH a good dehumidifier brand?
How its 4 dehumidifiers compare on efficiency with their DOE class is above. All 4 are filed under FRIEDRICH alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
Does FRIEDRICH make a 50 pint dehumidifier?
Yes, by the 2019 DOE test: 2 of its models certify 49.5 pints/day or more, led by FRIEDRICH D50B1B at 50 pints/day. How the 2019 test changed pint ratings.
Which FRIEDRICH dehumidifier is the most efficient for its size?
FRIEDRICH D35B1B, at IEF 1.9: higher than 60 of the 296 in its DOE class (portable dehumidifiers, 25 to 50 pints/day). At the other end are FRIEDRICH D50B1B, FRIEDRICH D35B1A and FRIEDRICH D50B1A, at IEF 1.8, higher than 4 of the 296 in its class.
