Best for basements
Frigidaire 50-Pint Dehumidifier
The basement standard: 50 pints a day, Energy Star rated.
Strengths
- 50 pints per day capacity covers up to 4,500 sq ft, the largest space rating here
- Energy Star certified, so it costs less to run than non-certified 50-pint units
- Continuous drain option plus a full-tank auto shutoff, so it never overflows
Limitations
- At around 44 lbs it is heavy to move, and it is too loud for bedrooms
- Large footprint; it needs floor space and clearance around the intake
- Overkill for small rooms, where it will short-cycle
What owners report
Commonly praised
- Pulls humidity down quickly in basements
- Built-in pump option for continuous drainage
- Quieter than expected at low speed
Common complaints
- Loud on high settings
- Some units fail after the first year
- Warranty claims can be frustrating

Questions, answered
What humidity level should a basement be?
Target 30 to 50% relative humidity. Above 60%, mold and dust mites thrive; below 30%, you waste energy and dry out stored items. Use the unit's humidistat rather than running it blindly.
Do I need a pump for basement drainage?
Only if your drain or sink is above the unit: gravity hoses need a downhill run. If the only drain is upstairs or across the room, get a model with a built-in pump or add an external condensate pump.
Will a dehumidifier stop basement mold?
It prevents new mold by keeping humidity below 60%, but it does not kill existing mold. Clean existing mold first, fix water intrusion, then use the dehumidifier to keep it from coming back.
