How efficient are DriSteem dehumidifiers?

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

DriSteem dehumidifiers against the median IEF (L/kWh) of their DOE class. DOE data as of 2026-11-03.
DOE class	DriSteem models	Above median	Class median	Best DriSteem
Whole home dehumidifiers (30)	3	2	IEF 2.13	RL-4 IEF 2.22

A higher IEF means more water removed per kWh.

Who makes DriSteem 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.

One of the 3 DriSteem basic models is filed under AprilAire's own model number (E070).

DriSteem shares 3 units with 5 other brands. Brands it shares with, and how many units each:

How much does a DriSteem dehumidifier cost to run?

Running nonstop at DOE's test conditions, the 3 DriSteem dehumidifiers with both figures use 14.17 to 21.48 kWh a day. That's about $2.57 to $3.90 a day, or $77.19 to $117.05 for 30 days. The lowest is DriSteem RL-3 (53 pints/day, IEF 1.77) and the highest DriSteem RL-6 (100.8 pints/day, IEF 2.22).

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 DriSteem

Is DriSteem a good dehumidifier brand?: How its 3 dehumidifiers compare on efficiency with their DOE class is above. One is filed under another company's model number (see who makes them above). We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
Does DriSteem make a 50 pint dehumidifier?: Yes, by the 2019 DOE test: 3 of its models certify 49.5 pints/day or more, led by DriSteem RL-6 at 100.8 pints/day. How the 2019 test changed pint ratings.
Which DriSteem dehumidifier is the most efficient for its size?: DriSteem RL-4 and DriSteem RL-6 tie at IEF 2.22: higher than 18 of the 30 in its DOE class (whole home dehumidifiers). At the other end is DriSteem RL-3, at IEF 1.77, tied with 1 other at DOE's 1.77 minimum.
Is DriSteem the same as Anden?: For 3 units, yes: both file them under the same DOE basic model (E070, E100 and E130). Compare the 3 brands of E070. Compare the 6 brands of E100. Compare the 5 brands of E130.
