Running cost
Among the thriftier 19–28 pint models
It uses 42 kWh a year less than the median 19–28 pint model. Over 11 years, the DOE’s average life for a portable, that’s about $85 saved in the United States.

Who it suits
On the ENERGY STAR table, the Sentinel Pro35X suits a damp space under 2,000 sq ft. For a very damp or wet one, the table asks for more. 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.
Same figures, other brand
An Argendon model with the same EPA figures
The company that files it with the EPA lists the Argendon Sandidry Pro35C with the same capacity, energy use, and efficiency. Check both prices, and both warranties, before you buy.
Ask before you buy
Ask how loud it is
No source we use gives a dB(A) figure for the Sentinel Pro35X. For a bedroom or an office, ask the seller for one, and for the distance it was measured from.
Quiet dehumidifier guideFrom the data
Where it stands
- At 242 kWh a year, it sits 42 kWh below the middle of its class.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- No Wi-Fi app.Not listed as connected.
- Tied for 2nd of 155 certified 19–28 pint portables for low energy use.
- Its efficiency, 1.90 liters per kWh, is 46% above the federal minimum for its capacity class.The DOE sets 1.30 L/kWh for portables rated 25 pints a day or less. Every unit made since June 13, 2019, must meet it.
- The smallest portable certified under the AlorAir name. Next up is the Helios D35, at 24 pints.That one uses 32 kWh a year more.
- On the market since March 2025, newer than 10% of the 19–28 pint models on the list.
- On the EPA’s Most Efficient list, like 30 other 19–28 pint models.
- The company that files it also files the Abestorm, Argendon, and BaseAire models with the EPA.
- The nearest size from another brand is the Argendon Sandidry Pro35C, rated 21 pints and 242 kWh a year.Both cost the same to run in the United States.

in the United States
A day of nonstop drying means 21.27 pints of water, about 2.7 gallons, for some 5.3 kWh. At the average home electricity price in the United States, the Sentinel Pro35X costs $0.97 to run that day.
The EPA’s yearly estimate, 242 kWh, adds up to about 46 days like that. Each extra day at full output costs another $0.97.
Those 21.27 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 2.7 gallons to get rid of. Check how the Sentinel Pro35X drains, since our sources don’t say.
