ComparisonTwo sizes

35 vs 50 pint dehumidifier

By Julien Fourel · How we compare

Updated Oct 16, 2026EPAEIA

The short answer

3PChoose 35 pints if

  • the room is very damp, under 2,000 sq ft: ENERGY STAR® suggests 25–40 pints a day.
  • you want the lower bill: 146 kWh a year less, about $27 in the United States.
  • it only feels a little humid: 20–30 pints is enough under 2,000 sq ft, so 35 leaves headroom.

5PChoose 50 pints if

  • the basement is wet, with standing water or laundry drying: under 2,000 sq ft, the range is 30–50 pints.
  • the area is over 2,000 sq ft and very damp or wet: 40+ or 50+ pints.
  • you’re between two sizes: the EPA says it’s better to oversize than undersize.
