How efficient are FreAire models?

Dehumidifiers

Of the 5 FreAire dehumidifiers, none files a higher IEF than the class median: 5 fall below it.

Air purifiers

Of the 7 FreAire air purifiers, 1 files a higher CADR/W than the class median and 6 fall below it.

A higher IEF means more water removed per kWh. A higher CADR/W means more clean air per watt.

Who makes FreAire dehumidifiers and air purifiers?

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.

One of the 12 FreAire basic models is filed under BAREN's own model number (HAP611WF).

FreAire shares 12 units with 7 other brands. Brands it shares with, and how many units each:

• ECOSELF11
• HASHONE9
• Aeitto2
• COOLTURE2
• Xenonlab2
• YTE Pro2
• BAREN1

How much do FreAire models cost to run?

Running nonstop at DOE's test conditions, the 5 FreAire dehumidifiers with both figures use 1.87 to 1.87 kWh a day. That's about 34¢ to 34¢ a day, or $10.18 to $10.18 for 30 days.

DOE's annual energy figures for the 7 FreAire air purifiers that file one run from 104 to 314 kWh a year: about $18.89 to $57.02 a year. The lowest is FreAire HAP-609 (72 cfm, CADR/W 4.5) and the highest FreAire HAP10 (219 cfm, CADR/W 4.5).

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 FreAire

Is FreAire a good dehumidifier brand?

How its 5 dehumidifiers compare on efficiency with their DOE class is above. 5 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 FreAire make a 50 pint dehumidifier?

No current DOE record shows one as of 2026-11-03. Its largest, FreAire YC12D6-MAX, certifies 5.25 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 FreAire dehumidifier is the most efficient for its size?

FreAire YC12D6-MAX, FreAire YC13D6-MAX, FreAire YC15D6-MAX and 2 more tie at IEF 1.33: higher than 69 of the 253 in its DOE class (portable dehumidifiers up to 25 pints/day).

Is FreAire the same as ECOSELF?

For 11 units, yes: both file them under the same DOE basic model (YC12D6-MAX, YC13D6-MAX, YC15D6-MAX, YC3D6-MAX and 7 more). The other FreAire basic model isn't filed by ECOSELF.
