Basements are naturally damp because they sit below ground, surrounded by cool soil. That moisture leads to musty smells, mildew on stored boxes, warped wood and, eventually, mold that can bother allergies and asthma. The best dehumidifier for a basement pulls that moisture out of the air and keeps humidity in the healthy range of about 30 to 50 percent.
We compared the most popular basement dehumidifiers on how quickly they remove moisture, energy use, tank size, noise and drainage options. Here are our picks for 2026.

The Midea Cube is the basement dehumidifier we would buy. Its lift-and-twist design puts a large tank underneath, so you empty it less often than a typical bucket.

It removes 50 pints a day and covers up to 4,500 square feet. You can control it with the Midea app or a voice assistant. It lists at $274.99, but it was out of stock on Midea’s store when we checked.

It adds Wi-Fi control and a turbo mode that raises the fan from 188 to 218 CFM. It is ENERGY STAR certified, which helps keep running costs down.

AEOCKY says the Rhea-001 earned ENERGY STAR Most Efficient 2025, a label few dehumidifiers get. That helps if it will run for many hours in a damp basement.
AEOCKY rates it at 56 pints a day in a warm, damp basement and 80 pints a day in very humid summer air. It covers up to 5,500 square feet.
It costs $299.99 on AEOCKY’s site. AEOCKY is a newer brand without the long track record of Midea or Frigidaire. The larger Rhea-003 costs $499.99.

This version of the Midea Cube adds that pump to the same lift-and-twist design as our top pick. It costs $299.99 on Midea’s site.
A pump is one more part that can wear out, so only choose this model if you really need it.

What size dehumidifier do you need for a basement?
For most basements, choose a 50-pint model (using the Department of Energy’s 2019 rating method). A larger unit dries the air faster and cycles on and off less, which saves energy and helps the compressor last longer. Smaller 20- to 35-pint models are better for bedrooms and bathrooms.
- Up to about 1,000 sq ft, moderately damp: 35 to 50 pints.
- 1,000 to 2,500 sq ft or musty smell: 50 pints.
- Very wet or larger basements: 50 pints with continuous drainage, or a whole-home unit.
How to choose a basement dehumidifier
1. Plan the drainage
A basement dehumidifier can fill its bucket more than once a day. Connecting a hose to a floor drain lets it run nonstop. With no drain nearby, choose a model with a built-in pump or buy a separate condensate pump.
2. Look at energy efficiency
A dehumidifier may run for hundreds of hours a year. Energy Star models and those with strong liters-per-kWh results cost less to run.
3. Check the humidity sensor
The dehumidifier uses its built-in sensor to turn on and off. An accurate sensor keeps your basement at your target humidity without wasting energy.
4. Consider low-temperature operation
Unfinished basements can be cool. Look for automatic defrost so the coils do not ice up when the room is below about 65°F.
5. Think about noise
If your basement is a living space or home office, pick a quieter model and use the lower fan speed once humidity is under control.
Tips for a drier basement
- Set the dehumidifier to about 45 to 50 percent humidity.
- Keep doors and windows closed while it runs.
- Clean the air filter every few weeks.
- Point gutters and downspouts away from the foundation.
- Use a cheap hygrometer in another corner to check the whole basement is dry.
- If water is leaking in, fix the source; a dehumidifier cannot stop flooding.
Frequently asked questions
What humidity should a basement be?
Aim for about 30 to 50 percent relative humidity. Above 60 percent, mold and dust mites grow much more easily.
How long should I run a dehumidifier in the basement?
Let it run on its humidity setting. At first it may run for most of the day, then cycle on and off once the basement dries out. Many homeowners run it year-round, especially in humid summers.
Where should I put a dehumidifier in the basement?
Place it in the center of the dampest area, at least a foot from walls and furniture, with the doors to other rooms closed. If you use a drain hose, place it near the floor drain.
Is a 50-pint dehumidifier too big for my basement?
Rarely. A 50-pint unit dries a basement faster and then turns off, which can use less energy than a small unit that runs constantly.
Can a dehumidifier get rid of mold?
A dehumidifier helps prevent mold by keeping humidity low, but it does not remove existing mold. Clean visible mold safely or hire a professional for large areas, then use the dehumidifier to stop it coming back.
How much does it cost to run a basement dehumidifier?
A 50-pint dehumidifier draws roughly 500 watts while running. Your cost depends on your electricity rate and how many hours it runs; an energy-monitoring smart plug can show you the exact cost.
The bottom line
For most homes, the Midea Cube 50-Pint is the best dehumidifier for a basement, thanks to its large lift-and-twist tank and included drain hose. Choose the Frigidaire 50-Pint for a simple all-rounder, hOmeLabs on a budget, the AEOCKY Rhea-001 for top efficiency, or the Midea Cube with Pump if you have no floor drain.
