Moiswell Aegis HP150 dehumidifier: specs and cost to run

Our read

Who it suits

Rated 50 pints a day, the Aegis HP150 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 $20 more 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 $185 over those years.

Wi-Fi app

You’ll check it in person

Like 141 other 45–50 pint models out of 156, the Aegis HP150 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 Aegis HP150. 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

At 530 kWh a year, it sits 10 kWh above the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Among the 156 certified 45–50 pint portables, 135 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.
The largest portable certified under the Moiswell name. Next down is the Aegis HP110, at 38 pints.That one uses 156 kWh a year less.
On the market since May 2026, newer than 90% of the 45–50 pint models on the list.Certified in June 2026, one of the 97 models certified in the last six months.
Not on the EPA’s Most Efficient list, which names 8 of the 45–50 pint models.
The Yoau UDZ1-150P is the closest size from another brand, rated 50 pints and 475 kWh a year.In the United States, this one costs $10 a year more to run.

in the United States

A day of nonstop drying means 50 pints of water, about 6.3 gallons, for some 11.8 kWh. At the average home electricity price in the United States, the Aegis HP150 costs $2.16 to run that day.

The EPA’s yearly estimate, 530 kWh, adds up to about 45 days like that. Each extra day at full output costs another $2.16.

Those 50 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 6.3 gallons to get rid of. Check how the Aegis HP150 drains, since our sources don’t say.
