Portable Dehumidifiers
A portable dehumidifier is a self-contained compressor unit on wheels that removes moisture from one area of the home. Most homes choose between 22-, 35- and 50-pint sizes under the current DOE rating. Pick the larger size if you are unsure, since it reaches the target faster and can cycle off more.
What to compare
- Pint rating: current ratings are measured at 65°F and 60% humidity. Old 70-pint models are roughly today's 50-pint class.
- Bucket size and full-tank shut-off: a larger bucket means fewer emptying trips.
- Continuous drain port: lets you attach a garden hose for gravity drainage.
- Built-in humidistat: set 45% to 50% and let it cycle.
- ENERGY STAR certification, and the energy factor (liters per kWh) where listed.
- Washable filter: clean it every few weeks to protect the coils.

FAQs
How long should a dehumidifier run each day?
Run it with the humidistat set to around 45% to 50% and let it cycle on and off as needed. In a damp basement in summer, that can mean running most of the day at first, then less once the space dries. A unit that never shuts off may be undersized or dealing with a leak.
Can I drain a dehumidifier into a hose?
Most portable dehumidifiers have a continuous drain port that accepts a standard garden hose. Water flows by gravity, so the hose must slope downhill to a floor drain or sink. If the drain is higher than the unit, choose a model with a built-in pump.
Do dehumidifiers use a lot of electricity?
A typical 35- to 50-pint compressor unit draws roughly 300 to 700 watts while running, but cycles off once the target humidity is reached. ENERGY STAR models remove more water per kilowatt-hour. Check the wattage and energy factor on the label to estimate your monthly cost.
