Our read
On the ENERGY STAR table, the Helios D35 suits a damp space under 2,000 sq ft. For a very damp or wet one, the table asks for more. 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
A portable lasts 11 years on average, by the DOE’s count. In that time, this model costs $20 less to run in the United States than the median 19–28 pint model. The thriftiest 19–28 pint model, the Knka PD30MA-20, would save $89 over those years.

No source we use gives a dB(A) figure for the Helios D35. For a bedroom or an office, ask the seller for one, and for the distance it was measured from.

in the United States
Run for a whole day at its rating, the Helios D35 removes 24 pints, about 3 gallons, on roughly 5.8 kWh. In the United States, that’s $1.07.
Divide the EPA’s 274 kWh a year by one full day’s use, and you get roughly 47 days. Past that, each day at full output adds $1.07 to the bill.
The DOE test behind those 24 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the Helios D35.
Without a hose or a pump, someone has to carry out 3 gallons a day. Our sources don’t say whether the Helios D35 has a bucket, or how much it holds.
Running cost
274 kWh a year × the home electricity price of each state.
