Running cost
Among the thriftier 45–50 pint models
It uses 49 kWh a year less than the median 45–50 pint model. Over 11 years, the DOE’s average life for a portable, that’s about $99 saved in the United States.

Who it suits
On the ENERGY STAR table, the CTH150B suits a wet space under 2,000 sq ft, or a very damp one over. It’s one of the cheaper models of its size to run.

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 141 other 45–50 pint models out of 156, the CTH150B has no Wi-Fi app on the EPA list. In a basement you rarely visit, plan to check it in person.
Crawl space dehumidifier guideAsk before you buy
Ask about the pump, and about the cold
Our sources don’t say whether the CTH150B 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.

Where it stands
- Uses 471 kWh a year, 49 kWh under the median of its class.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- Tied for 3rd of 156 certified 45–50 pint portables for low energy use.
- Its efficiency, 2.20 liters per kWh, is 38% 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 CHWA120A, at 37 pints. The next size up is the CHWA150B, at 50 pints.The bigger one uses 28 kWh a year more.
- On the market since September 2026, newer than 97% of the 45–50 pint models on the list.Certified in September 2026, one of the 97 models certified in the last six months.
- On the EPA’s Most Efficient list, like 7 other 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 MegaLight PD-HPC750-WT, rated 49 pints and 472 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 CTH150B removes 49.43 pints, about 6.2 gallons, on roughly 10.6 kWh. In the United States, that’s $1.95.
Divide the EPA’s 471 kWh a year by one full day’s use, and you get roughly 44 days. Past that, each day at full output adds $1.95 to the bill.
The DOE test behind those 49.43 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the CTH150B.
Without a hose or a pump, someone has to carry out 6.2 gallons a day. Our sources don’t say whether the CTH150B has a bucket, or how much it holds.
