Running cost
Among the thriftier 29–44 pint models
It uses 31 kWh a year less than the median 29–44 pint model. Over 11 years, the DOE’s average life for a portable, that’s about $62 saved in the United States.

Who it suits
On the ENERGY STAR table, the CTH120A suits a wet space under 2,000 sq ft, or a damp one over. It’s one of the cheaper models of its size to run.
32 pints a day

Capacity suggested for each case, read Oct 5, 2026. ENERGY STAR adds that it’s better to oversize than undersize.
Wi-Fi app
You’ll check it in person
Like 78 other 29–44 pint models out of 87, the CTH120A has no Wi-Fi app on the EPA list. In a basement you rarely visit, plan to check it in person.

Ask about the pump, and about the cold
Our sources don’t say whether the CTH120A 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.
Plan the drainFrom the data
Where it stands
- Its 343 kWh a year is 31 kWh less than the median for its size.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- Among the 87 certified 29–44 pint portables, 16 use less energy.
- The federal floor for its class is 1.60 liters per kWh. It reaches 2.01, or 26% more.That floor covers portables rated over 25 and up to 50 pints a day, for units made since June 13, 2019.
- In the Waykar lineup, the next size down is the JD025CE-80, at 25 pints. The next size up is the YDA-120, at 35 pints.The bigger one uses 39 kWh a year more.
- On the market since April 2026, newer than 84% 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 hOmeLabs HME0089 is the closest size from another brand, rated 32 pints and 343 kWh a year.Both cost the same to run in the United States.

in the United States
Run for a whole day at its rating, the CTH120A removes 32.46 pints, about 4.1 gallons, on roughly 7.6 kWh. In the United States, that’s $1.40.
Divide the EPA’s 343 kWh a year by one full day’s use, and you get roughly 45 days. Past that, each day at full output adds $1.40 to the bill.
The DOE test behind those 32.46 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the CTH120A.
Without a hose or a pump, someone has to carry out 4.1 gallons a day. Our sources don’t say whether the CTH120A has a bucket, or how much it holds.
