Waykar CTH30A dehumidifier: specs and cost to run

Our read

Who it suits

At 9 pints a day, the CTH30A sits below the smallest size in the ENERGY STAR table. That size is 20 pints, for a damp room under 2,000 sq ft. Kesnos lists two models with the same EPA figures, so compare prices.

Capacity suggested for each case, read Oct 5, 2026. ENERGY STAR adds that it’s better to oversize than undersize.

Running cost

Running cost won’t decide it

It uses 117 kWh a year, the median for 13-pint and smaller models. The nine thriftiest of its size would each save $24 in the United States over 11 years, the DOE’s average life for a portable. One is the Concetta AS-CSJ72XK-2WT-OL.

Same figures, other brand

A Kesnos model with the same EPA figures

The company that files it with the EPA lists the Kesnos CTH30B and CTH30E with the same capacity, energy use, and efficiency. Compare their prices and warranties before you choose.

Ask before you buy

Ask how loud it is

No source we use gives a dB(A) figure for the CTH30A. For a bedroom or an office, ask the seller for one, and for the distance it was measured from.

in the United States

A day of nonstop drying means 9.2 pints of water, about 1.1 gallons, for some 2.6 kWh. At the average home electricity price in the United States, the CTH30A costs $0.47 to run that day.

The EPA’s yearly estimate, 117 kWh, adds up to about 46 days like that. Each extra day at full output costs another $0.47.

Those 9.2 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 1.1 gallons to get rid of. Check how the CTH30A drains, since our sources don’t say.
