Buying advice: dehumidifiers
- Under the current Department of Energy test standard, 20 to 35 pint models suit moderately damp rooms and 50 pint models suit wet basements. Buying slightly larger lets the unit run less often.
- Emptying a bucket daily gets old fast. A hose connection to a floor drain, or a built-in pump to lift water to a sink, allows continuous running.
- Cool basements can cause coils to frost. Check the minimum operating temperature and whether the unit has auto-defrost.
- A built-in humidistat switches the unit on and off around your target. An inexpensive separate hygrometer helps you check it is reading correctly.
- Compressor dehumidifiers hum like a small fridge. Energy Star certified models remove more water per kilowatt-hour.

What size dehumidifier do I need for a basement?
For a typical 1,000 to 1,500 square foot basement with visible dampness or a musty smell, a 30 to 35-pint unit is usually enough. For basements over 1,500 square feet, standing water history, or noticeably high humidity, step up to a 50-pint unit rated for 4,000 to 4,500 square feet. Undersizing means the compressor runs constantly without ever pulling humidity down to a comfortable range.
Does a basement dehumidifier need a pump?
Not always, but it removes the most annoying part of ownership. Without a pump, you empty a 1.8-gallon bucket by hand, sometimes more than once a day in a damp basement. A built-in pump pushes the water up and out through a hose to a sink, floor drain, or window, so the unit runs continuously without anyone checking on it. If your basement has a nearby drain or a sink within hose reach, a pump model pays for itself in convenience within the first month.
