Waykar CHWA150A dehumidifier: specs and cost to run

Our read

Who it suits

Rated 50 pints a day, the CHWA150A is sized for every space in the ENERGY STAR table, wet ones over 2,000 sq ft included. Its yearly energy use sits near the median, so weigh drainage, noise, and price.

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 $32 less to run in the United States than the median 45–50 pint model. The thriftiest 45–50 pint model, the Aeocky LEO PRO-RCS50(Y)-N4-3(B)-25, would save $133 over those years.

How long dehumidifiers last

Wi-Fi app

You’ll check it in person

Like 141 other 45–50 pint models out of 156, the CHWA150A has no Wi-Fi app on the EPA list. In a basement you rarely visit, plan to check it in person.

Ask before you buy

Ask about the pump, and about the cold

Neither figure is in our sources for the CHWA150A. 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 504 kWh a year is 16 kWh less than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 25th of 156 certified 45–50 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.
Waykar’s next size down is the JD026CE-150, rated 49 pints.That one uses 3 kWh a year more.
Sold since July 2025. Among 45–50 pint models, 23 of 156 came out earlier.
Not on the EPA’s Most Efficient list, which names 8 of the 45–50 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 Midea MAD50PS1QWT-A, rated 50 pints and 515 kWh a year.In the United States, this one costs $2 a year less to run.

in the United States

Run for a whole day at its rating, the CHWA150A removes 49.67 pints, about 6.2 gallons, on roughly 11.7 kWh. In the United States, that’s $2.14.

Divide the EPA’s 504 kWh a year by one full day’s use, and you get roughly 43 days. Past that, each day at full output adds $2.14 to the bill.

The DOE test behind those 49.67 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the CHWA150A.

Without a hose or a pump, someone has to carry out 6.2 gallons a day. Our sources don’t say whether the CHWA150A has a bucket, or how much it holds.
