Dayton: 6 DOE certified models
Dayton has 6 basic models certified to DOE as of 2026-11-03: 3 portable ACs (5,300 to 8,000 BTU/h SACC) and 3 dehumidifiers (22.31 to 49.66 pints/day under the 2019 DOE test). How their efficiency compares with their DOE class is below.
Key findings
- Highest certified cooling capacity among its portable ACs: Dayton 60YP71A at 8,000 BTU/h SACC.
- Most efficient for its class: Dayton 60YP71A, CEER 7.2, higher than 311 of the 1,044 single hose portable ACs certified to DOE.
- Highest certified water removal among its dehumidifiers: Dayton 821P88A at 49.66 pints/day.

How efficient are Dayton models?
Portable air conditioners
Of the 3 Dayton portable ACs, none files a higher CEER than the class median: 3 fall below it.
| Class | Dayton models | Above median | Class median | Best Dayton |
|---|---|---|---|---|
| Single hose portable ACs (1,044) | 3 | 0 | CEER 7.3 | 60YP71A CEER 7.2 |
Dehumidifiers
Of the 3 Dayton dehumidifiers, none files a higher IEF than the class median: 1 matches it and 2 fall below it.
| DOE class | Dayton models | Above median | Class median | Best Dayton |
|---|---|---|---|---|
| Portable dehumidifiers, 25 to 50 pints/day (296) | 2 | 0 | IEF 1.91 | 821P88A IEF 1.9 |
| Portable dehumidifiers up to 25 pints/day (253) | 1 | 0 | IEF 1.7 | 821P87A IEF 1.7 |
A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh.
Who makes Dayton 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.
None of the 6 Dayton 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 Dayton alone.
How much do Dayton models cost to run?
While cooling, Dayton portable ACs draw about 815 to 1,111 W (certified SACC divided by CEER). That's 15¢ to 20¢ an hour, or $35.54 to $48.43 for 30 days at 8 hours a day. The lowest is Dayton 60YP69A (5,300 BTU/h SACC, CEER 6.5) and the highest Dayton 60YP71A (8,000 BTU/h SACC, CEER 7.2).
Running nonstop at DOE's test conditions, the 3 Dayton dehumidifiers with both figures use 6.21 to 12.37 kWh a day. That's about $1.13 to $2.25 a day, or $33.83 to $67.38 for 30 days. The lowest is Dayton 821P87A (22.31 pints/day, IEF 1.7) and the highest Dayton 821P88A (49.66 pints/day, IEF 1.9).
Real use cycles on and off with the humidity, so the dehumidifier figures are the upper end for a day of nonstop running.

Questions about Dayton
- Is Dayton a good dehumidifier brand?
- How its 3 dehumidifiers compare on efficiency with their DOE class is above. All 3 are filed under Dayton alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
- Does Dayton make a 50 pint dehumidifier?
- Yes, by the 2019 DOE test: Dayton 821P88A certifies 49.66 pints/day. By DOE class: 1 in the up to 25 pints/day class and 2 in the 25 to 50 pints/day class. How the 2019 test changed pint ratings.
- Which Dayton dehumidifier is the most efficient for its size?
- Dayton 821P87A, at IEF 1.7: higher than 94 of the 253 in its DOE class (portable dehumidifiers up to 25 pints/day). At the other end are Dayton 821P88A and Dayton 821P89A, at IEF 1.9, higher than 60 of the 296 in its class.
