Our read
On the ENERGY STAR table, the CHWA120B suits a wet space under 2,000 sq ft, or a damp one over. Its yearly energy use sits near the median, so weigh drainage, noise, and price.
35 pints a day
| How damp the space is | Under 2,000 sq ft | Over 2,000 sq ft |

Capacity suggested for each case, read Oct 5, 2026. ENERGY STAR adds that it’s better to oversize than undersize.
Running cost
A portable lasts 11 years on average, by the DOE’s count. In that time, this model costs $28 less to run in the United States than the median 29–44 pint model. The thriftiest 29–44 pint model, the Deciuu LIBRA-RCS32(Y)-N4-3(B), would save $54 over those years.
How long dehumidifiers lastWi-Fi app
Like 78 other 29–44 pint models out of 87, the CHWA120B has no Wi-Fi app on the EPA list. In a basement you rarely visit, plan to check it in person.

Our sources don’t say whether the CHWA120B has a pump, or how cold it can run. With no drain lower than the unit, the pump lift must reach your sink. Under 65°F, ENERGY STAR says the coils can frost.

in the United States
Run for a whole day at its rating, the CHWA120B removes 35.2 pints, about 4.4 gallons, on roughly 8.3 kWh. In the United States, that’s $1.52.
Divide the EPA’s 360 kWh a year by one full day’s use, and you get roughly 43 days. Past that, each day at full output adds $1.52 to the bill.
The DOE test behind those 35.2 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the CHWA120B.
Without a hose or a pump, someone has to carry out 4.4 gallons a day. Our sources don’t say whether the CHWA120B has a bucket, or how much it holds.
Running cost
360 kWh a year × the home electricity price of each state.
