Our read
Who it suits
Rated 50 pints a day, the NS-DH50WH7 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.
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 $16 less 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 $149 over those years.
Like 141 other 45–50 pint models out of 156, the NS-DH50WH7 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-DH50WH7. 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 512 kWh a year, it sits 8 kWh below the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 43rd of 156 certified 45–50 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.
Insignia’s next size down is the NS-DH35WH7, rated 36 pints.That one uses 129 kWh a year less.
Sold since June 2025. Among 45–50 pint models, 12 of 156 came out earlier.
Not on the EPA’s Most Efficient list, which names 8 of the 45–50 pint models.
The nearest size from another brand is the Frigidaire FHDD5033Y1, rated 50 pints and 520 kWh a year.In the United States, this one costs $1 a year less to run.

in the United States
In 24 hours at full output, the NS-DH50WH7 pulls about 6.2 gallons of water from the air and uses about 11.8 kWh. That day costs $2.15 in the United States.
About 44 such days make up the EPA’s yearly estimate of 512 kWh. If yours runs at full output more often, every extra day adds $2.15.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the NS-DH50WH7 pulls out less than 49.95 pints a day.
Those 6.2 gallons need a way out: a hose to a drain, a pump, or a bucket you empty. Our sources don’t say which ones the NS-DH50WH7 has.
