How efficient are MANASTIN models?
Portable air conditioners
Of the 8 MANASTIN portable ACs, 4 file a higher CEER than the class median and 4 fall below it.
| Class | MANASTIN models | Above median | Class median | Best MANASTIN |
|---|---|---|---|---|
| Single hose portable ACs (1,044) | 8 | 4 | CEER 7.3 | MS1309PAC14 CEER 8.1 |
Dehumidifiers
MANASTIN FDD25-516AV1R5 files IEF 1.39 L/kWh. The median among the 253 models in its DOE class (portable dehumidifiers up to 25 pints/day) is 1.7, so it's below the median: higher than 79 of the 253.
A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh.
Who makes MANASTIN 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.
MANASTIN shares 5 units with 11 other brands. Its other 4 basic models are filed by MANASTIN alone. Brands it shares with, and how many units each:
| Basic model | MANASTIN model | Number belongs to | Brands |

| OL- | OL- | No known prefix | 12 |
| OL- | OL- | No known prefix | 12 |

How much do MANASTIN models cost to run?
While cooling, MANASTIN portable ACs draw about 746 to 1,272 W (certified SACC divided by CEER). That's 14¢ to 23¢ an hour, or $32.53 to $55.42 for 30 days at 8 hours a day. The lowest is MANASTIN MS1308PAC8 (5,300 BTU/h SACC, CEER 7.1) and the highest MANASTIN MS1309PAC14 (10,300 BTU/h SACC, CEER 8.1).
MANASTIN FDD25-516AV1R5 certifies 19 pints/day (8.99 liters) at an IEF of 1.39 L/kWh. That takes 6.47 kWh a day running nonstop at DOE's test conditions: about $1.17 a day, or $35.24 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 MANASTIN
- Is MANASTIN a good dehumidifier brand?
- Its one dehumidifier basic model, MANASTIN FDD25-516AV1R5, certifies 19 pints/day under the 2019 DOE test, and its IEF of 1.39 is higher than 79 of the 253 in its DOE class (portable dehumidifiers up to 25 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 MANASTIN make a 50 pint dehumidifier?
- No current DOE record shows one as of 2026-11-03. Its one model, MANASTIN FDD25-516AV1R5, certifies 19 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.
- Is MANASTIN the same as KINETHEME?
- For 5 units, yes: both file them under the same DOE basic model (OL-A016JA05N3, OL-A016JA06N3, OL-A018ED08N3/S, OL-A018ED10N3B1/S and 1 more). The other 4 MANASTIN basic models aren't filed by KINETHEME.
