How efficient are MEPTY models?

Portable air conditioners

Of the 18 MEPTY portable ACs, 9 file a higher CEER than the class median and 9 fall below it.

Dehumidifiers

Of the 4 MEPTY dehumidifiers, 4 file a higher IEF than the class median.

A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh.

Who makes MEPTY 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.

MEPTY shares 12 units with 35 other brands. Its other 10 basic models are filed by MEPTY alone. Brands it shares with, and how many units each:

• AKIRES10
• Uthfy8
• KEGIAN4
• Landeagle4
• GUNJI2
• KAIMENG2
• KINETHEME2
• MANASTIN2
• Mountman2
• Nepsam2
• NEXARO2
• Patiosunny2
• SUNGDOGIN2
• TEHANLD2
• UrbanSync2
• AIR CHOICE1
• Antarctic Star1
• Auseo1
• AZ outdoor1
• COWSAR1
• Electactic1
• Fornido1
• Havato1
• Joy Pebble1

How much do MEPTY models cost to run?

While cooling, MEPTY portable ACs draw about 746 to 1,291 W (certified SACC divided by CEER). That's 14¢ to 23¢ an hour, or $32.53 to $56.27 for 30 days at 8 hours a day. The lowest is MEPTY HY08MAC001 (5,300 BTU/h SACC, CEER 7.1) and the highest MEPTY HYMAC14CD1 (10,200 BTU/h SACC, CEER 7.9).

Running nonstop at DOE's test conditions, the 4 MEPTY dehumidifiers with both figures use 8.38 to 8.38 kWh a day. That's about $1.52 to $1.52 a day, or $45.68 to $45.68 for 30 days.

Real use cycles on and off with the humidity, so the dehumidifier figures are the upper end 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 MEPTY

Is MEPTY a good dehumidifier brand?

How its 4 dehumidifiers compare on efficiency with their DOE class is above. 2 of them are 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 MEPTY make a 50 pint dehumidifier?

No current DOE record shows one as of 2026-11-03. Its largest, MEPTY HY35DE001, certifies 35.97 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.

Which MEPTY dehumidifier is the most efficient for its size?

MEPTY HY35DE001, MEPTY ME-HY35DE001, MEPTY ME-OL35-D076FFN3B1/E and 1 more tie at IEF 2.03: higher than 280 of the 296 in its DOE class (portable dehumidifiers, 25 to 50 pints/day).

Is MEPTY the same as AKIRES?

For 10 units, yes: both file them under the same DOE basic model (HY08MAC001, HY10MAC001, HY12MAC003, HY14MAC003 and 6 more). The other 12 MEPTY basic models aren't filed by AKIRES.
