Dehumidifiers
Brothers 301090 files IEF 2.01 L/kWh. The median among the 296 models in its DOE class (portable dehumidifiers, 25 to 50 pints/day) is 1.91, so it's above the median: higher than 161 of the 296.
A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh.
Who makes Brothers portable ACs, window ACs and 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 16 Brothers 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 Brothers alone.
How much do Brothers models cost to run?
While cooling, Brothers portable ACs draw about 820 to 1,266 W (certified SACC divided by CEER). That's 15¢ to 23¢ an hour, or $35.72 to $55.17 for 30 days at 8 hours a day. The lowest is Brothers 102135 (5,000 BTU/h SACC, CEER 6.1) and the highest Brothers 102133 (10,000 BTU/h SACC, CEER 7.9).
While cooling, Brothers window ACs draw about 490 to 1,580 W (DOE's listed power input). That's 9¢ to 29¢ an hour, or $21.36 to $68.86 for 30 days at 8 hours a day. The lowest is Brothers 102372 (5,000 BTU/h, CEER 14.4) and the highest Brothers 102387 (18,000 BTU/h, CEER 16).
Brothers 301090 certifies 49.74 pints/day (23.54 liters) at an IEF of 2.01 L/kWh. That takes 11.71 kWh a day running nonstop at DOE's test conditions: about $2.13 a day, or $63.79 for 30 days.
Real use cycles on and off with the humidity, so that's the upper figure 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 Brothers
- Is Brothers a good dehumidifier brand?
- Its one dehumidifier basic model, Brothers 301090, certifies 49.74 pints/day under the 2019 DOE test, and its IEF of 2.01 is higher than 161 of the 296 in its DOE class (portable dehumidifiers, 25 to 50 pints/day). We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
- Does Brothers make a 50 pint dehumidifier?
- Yes, by the 2019 DOE test: Brothers 301090 certifies 49.74 pints/day. How the 2019 test changed pint ratings.
