How efficient are Gasbye models?
Portable air conditioners
Of the 2 Gasbye portable ACs, 1 files a higher CEER than the class median and 1 falls below it.
| Class | Gasbye models | Above median | Class median | Best Gasbye |
|---|---|---|---|---|
| Dual hose portable ACs (334) | 2 | 1 | CEER 12.5 | CoolPrime 12000- |
Dehumidifiers
Gasbye DryPrime-50-B 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 Gasbye portable 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.
Gasbye shares one unit with one other brand, DuraComfort. Its other 2 basic models are filed by Gasbye alone.
| Basic model | Gasbye model | Number belongs to | Brands |

How much do Gasbye models cost to run?
While cooling, Gasbye portable ACs draw about 954 to 1,137 W (certified SACC divided by CEER). That's 17¢ to 21¢ an hour, or $41.57 to $49.55 for 30 days at 8 hours a day. The lowest is Gasbye CoolPrime 12000-W (12,400 BTU/h SACC, CEER 13) and the highest Gasbye CoolPrime 8000-B (8,300 BTU/h SACC, CEER 7.3).
Gasbye DryPrime-50-B certifies 49.7 pints/day (23.52 liters) at an IEF of 2.01 L/kWh. That takes 11.7 kWh a day running nonstop at DOE's test conditions: about $2.12 a day, or $63.74 for 30 days.
Real use cycles on and off with the humidity, so that's the upper figure for a day of nonstop running.

Questions about Gasbye
- Is Gasbye a good dehumidifier brand?
- Its one dehumidifier basic model, Gasbye DryPrime-50-B, certifies 49.7 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). It's the same unit as another brand's model. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
- Does Gasbye make a 50 pint dehumidifier?
- Yes, by the 2019 DOE test: Gasbye DryPrime-50-B certifies 49.7 pints/day. How the 2019 test changed pint ratings.
- Is Gasbye the same as DuraComfort?
- For one unit, yes: both file it under the same DOE basic model (DEM 50EPD). The other 2 Gasbye basic models aren't filed by DuraComfort. Compare the 2 brands of DEM 50EPD.
