Waykar CHWA120A dehumidifier: specs and cost to run

Our read

Who it suits

Rated 37 pints a day, the CHWA120A is sized for a wet space under 2,000 sq ft, or a damp one over. Its running cost is close to the median, so drainage, noise, and price matter more.

Running cost

Running cost won’t decide it

The DOE puts a portable’s average life at 11 years. Over that time, this model costs $10 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 $73 over those years.

The EPA doesn’t list the CHWA120A as connected. Of the 87 certified 29–44 pint models, 8 are. In a crawl space you rarely open, a connected one saves the trip.

Ask before you buy

Ask for the pump lift and the lowest working temperature

Neither figure is in our sources for the CHWA120A. Without a floor drain below it, a pump has to lift the water to a sink. Basements run cool, and below 65°F, ENERGY STAR says frost can form on the coils.

From the data

Where it stands

Its 369 kWh a year is 5 kWh less than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 37th of 87 certified 29–44 pint portables for low energy use.
Its efficiency, 2.01 liters per kWh, is 26% above the federal minimum for its capacity class.The DOE sets 1.60 L/kWh for portables rated over 25 and up to 50 pints a day. Every unit made since June 13, 2019, must meet it.
In the Waykar lineup, the next size down is the JD025CE-120, at 36 pints. The next size up is the CTH150B, at 49 pints.The bigger one uses 102 kWh a year more.
On the market since July 2025, newer than 32% of the 29–44 pint models on the list.
Not on the EPA’s Most Efficient list, which names 1 of the 29–44 pint models.
The company that files it also files the Fehom, Kesnos, and Yaufey models with the EPA.
The nearest size from another brand is the AUX ADT35V1, rated 37 pints and 369 kWh a year.Both cost the same to run in the United States.

in the United States

A day of nonstop drying means 36.9 pints of water, about 4.6 gallons, for some 8.7 kWh. At the average home electricity price in the United States, the CHWA120A costs $1.59 to run that day.

The EPA’s yearly estimate, 369 kWh, adds up to about 42 days like that. Each extra day at full output costs another $1.59.

Those 36.9 pints come from a DOE test at 65°F and 60% humidity. Cooler air at that humidity gives up less water, so expect fewer pints in a cold basement.

Every day at full output leaves 4.6 gallons to get rid of. Check how the CHWA120A drains, since our sources don’t say.
