Our read
Who it suits
Rated 36 pints a day, the NS-DH35WH7 is sized for a wet space under 2,000 sq ft, or a damp one over. Its yearly energy use sits near the median, so weigh drainage, noise, and price.
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
The DOE puts a portable’s average life at 11 years. Over that time, this model costs $18 more to run in the United States than the median 29–44 pint model. The thriftiest 29–44 pint model, the Deciuu LIBRA-RCS32(Y)-N4-3(B), would save $101 over those years.
Like 78 other 29–44 pint models out of 87, the NS-DH35WH7 has no Wi-Fi app on the EPA list. In a basement you rarely visit, plan to check it in person.
Neither figure is in our sources for the NS-DH35WH7. 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.
At 383 kWh a year, it sits 9 kWh above the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 72nd of 87 certified 29–44 pint portables for low energy use.
Its efficiency, 2.01 liters per kWh, is 26% 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.
The smallest portable certified under the Insignia name. Next up is the NS-DH50WH7, at 50 pints.That one uses 129 kWh a year more.
On the market since June 2025, newer than 21% 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 nearest size from another brand is the BLACK+DECKER BDM36WCDA, rated 36 pints and 383 kWh a year.Both cost the same to run in the United States.

A day of nonstop drying means 36.39 pints of water, about 4.5 gallons, for some 8.6 kWh. At the average home electricity price in the United States, the NS-DH35WH7 costs $1.57 to run that day.
The EPA’s yearly estimate, 383 kWh, adds up to about 45 days like that. Each extra day at full output costs another $1.57.
Those 36.39 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 4.5 gallons to get rid of. Check how the NS-DH35WH7 drains, since our sources don’t say.
