Running cost
Among the thriftier 45–50 pint models
It uses 48 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 $97 saved in the United States.

Who it suits
On the ENERGY STAR table, the PD-HPC750-WT 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.

The EPA doesn’t list the PD-HPC750-WT as connected. Of the 156 certified 45–50 pint models, 14 are. In a crawl space you rarely open, a connected one saves the trip.

Ask for the pump lift and the lowest working temperature
Our sources don’t say whether the PD-HPC750-WT 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 472 kWh a year is 48 kWh less than the median for its size.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- Among the 156 certified 45–50 pint portables, 6 use less energy.
- The federal floor for its class is 1.60 liters per kWh. It reaches 2.20, or 38% more.That floor covers portables rated over 25 and up to 50 pints a day, for units made since June 13, 2019.
- The largest portable certified under the MegaLight name. Next down is the PD-MPC720-WT, at 25 pints.That one uses 189 kWh a year less.
- On the market since March 2026, newer than 81% of the 45–50 pint models on the list.
- On the EPA’s Most Efficient list, like 7 other 45–50 pint models.
- The Waykar CTH150B is the closest size from another brand, rated 49 pints and 471 kWh a year.Both cost the same to run in the United States.

Run for a whole day at its rating, the PD-HPC750-WT 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 472 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 PD-HPC750-WT.
Without a hose or a pump, someone has to carry out 6.2 gallons a day. Our sources don’t say whether the PD-HPC750-WT has a bucket, or how much it holds.
