WAA: 6 DOE certified models
WAA has 6 basic models certified to DOE as of 2026-11-03: 2 portable ACs (5,000 to 6,000 BTU/h SACC) and 4 dehumidifiers (24.83 to 49.86 pints/day under the 2019 DOE test). 6 are the same unit as models filed under other brands. How their efficiency compares with their DOE class is below.
Key findings
- Highest certified cooling capacity among its portable ACs: WAA NPPB2A-06C/X1E at 6,000 BTU/h SACC.
- Most efficient for its class: WAA NPPB2A-06C/X1E, CEER 6.7, higher than 220 of the 1,044 single hose portable ACs certified to DOE.
- Highest certified water removal among its dehumidifiers: WAA D026W-50Pt3M at 49.86 pints/day.

How efficient are WAA models?
Portable air conditioners
Of the 2 WAA portable ACs, none files a higher CEER than the class median: 2 fall below it.
| Class | WAA models | Above median | Class median | Best WAA |
|---|---|---|---|---|
| Single hose portable ACs (1,044) | 2 | 0 | CEER 7.3 | NPPB2A- |
Dehumidifiers
Of the 4 WAA dehumidifiers, 2 file a higher IEF than the class median and 2 match it.
| DOE class | WAA models | Above median | Class median | Best WAA |
|---|---|---|---|---|
| Portable dehumidifiers, 25 to 50 pints/day (296) | 3 | 2 | IEF 1.91 | D026W- |
| Portable dehumidifiers up to 25 pints/day (253) | 1 | 0 | IEF 1.7 | 75025EDE0- |
A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh.
Who makes WAA 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.

How much do WAA models cost to run?
While cooling, WAA portable ACs draw about 794 to 896 W (certified SACC divided by CEER). That's 14¢ to 16¢ an hour, or $34.59 to $39.03 for 30 days at 8 hours a day. The lowest is WAA NPPB2A-05C/X1E (5,000 BTU/h SACC, CEER 6.3) and the highest WAA NPPB2A-06C/X1E (6,000 BTU/h SACC, CEER 6.7).
Running nonstop at DOE's test conditions, the 4 WAA dehumidifiers with both figures use 6.91 to 11.71 kWh a day. That's about $1.26 to $2.13 a day, or $37.65 to $63.79 for 30 days. The lowest is WAA 75025EDE0-WHITE-EL (24.83 pints/day, IEF 1.7) and the highest WAA 75026EDE0-WHITE-EL (49.74 pints/day, IEF 2.01).
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 WAA
- Is WAA a good dehumidifier brand?
- How its 4 dehumidifiers compare on efficiency with their DOE class is above. 4 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 WAA make a 50 pint dehumidifier?
- Yes, by the 2019 DOE test: 2 of its models certify 49.5 pints/day or more, led by WAA D026W-50Pt3M at 49.86 pints/day. By DOE class: 1 in the up to 25 pints/day class and 3 in the 25 to 50 pints/day class. How the 2019 test changed pint ratings.
- Which WAA dehumidifier is the most efficient for its size?
- WAA D026W-50Pt3M, at IEF 2.2: higher than 293 of the 296 in its DOE class (portable dehumidifiers, 25 to 50 pints/day). At the other end is WAA 75025EDE0-WHITE-EL, at IEF 1.7, higher than 94 of the 253 in its class.
- Is WAA the same as Antarctic Star?
- For 6 units, yes: both file them under the same DOE basic model (NPP-05C/X1E, NPP-06H/X1E, 75025EDE0-WHITE-EL, 75025EDE1-WHITE-EL and 2 more).
