Basements trap moisture, humidity, and stale air more than any other part of the home. Left unchecked, that moisture can lead to mold growth, musty odors, and even structural damage over time.
If you’re looking for the best dehumidifier for a basement, the right choice depends on basement size, humidity levels, and whether you want a hands-off drainage setup or a simple bucket system.
This guide breaks down the best basement dehumidifiers, what features matter most, and how to choose the right unit for your space.

What to Look for in a Basement Dehumidifier
Not all dehumidifiers are built for basement conditions. Here’s what actually matters:
Pint Capacity
Most basements need a 30–70 pint dehumidifier.
- Small or mildly damp basements: 30–40 pint
- Large or very damp basements: 50–70 pint
Drainage Options
- Bucket: Manual emptying
- Drain Hose: Continuous drainage to a floor drain
- Built-in Pump: Pumps water upward to a sink or window (best option)
Energy Efficiency
Look for Energy Star-rated units to keep operating costs low.
Noise Level
Basements are usually out of the way, but quieter units matter for finished basements or living spaces.

How Big of a Dehumidifier Do You Need for a Basement?
A general rule:
- Up to 1,500 sq ft: 30–40 pint
- 1,500–2,500 sq ft: 50 pint
- Very damp or flooded areas: 70 pint
Always size up if your basement has standing moisture, poor ventilation, or past water issues.
Should You Get a Dehumidifier With a Pump?
A pump is worth it if:
- You don’t want to empty buckets
- You don’t have a nearby floor drain
- You want continuous, unattended operation
If you can run a drain hose downhill, a pump isn’t necessary.

For most homes, the hOmeLabs 50 Pint Dehumidifier offers the best balance of performance, reliability, and price.
If you have a large basement or severe moisture problems, stepping up to a higher-capacity model or a unit with a built-in pump can save time and hassle in the long run.
If your basement has experienced flooding or water intrusion, installing a reliable sump pump backup system can add an extra layer of protection.
