Which dehumidifier is best for basements?

Mitigate mold and mildew

Basements have a bad habit of retaining moisture in the air, leading to unpleasant smells, mold and mildew. Dehumidifiers are a perfect way to control your basement's humidity level. Still, with so many options, it can take time to find the right one. If you're looking for a new dehumidifier, there are a few things you should consider before making a purchase. We rounded up the best basement dehumidifier options to consider for your home.

Choosing the best humidifier for your basement

Size and portability

Your basement's size is an essential consideration, as it will affect how large a dehumidifier you need. Those with a capacity of at least 20 pints are ideal for basements up to 1,000 square feet, although you may want a model with at least a 40-pint capacity to reduce the number of times you'll need to empty it each day. On the other hand, it's best to buy a dehumidifier with at least a 50-pint capacity for larger spaces.

It's also worth considering your basement's average temperature when determining how large your dehumidifier should be. Hotter rooms generally hold more water vapor in the air, meaning you'll have to empty your dehumidifier more often if your basement stays fairly warm.

If you plan on moving your dehumidifier around your basement, you may want a unit with wheels and handles. Those meant for larger spaces tend to be bigger and heavier, but you're less likely to need to move them around.

Continuous drainage

If your basement has a floor-level drain, it's worth considering a dehumidifier with a continuous drainage feature.

Most dehumidifiers must be emptied regularly, but those with continuous drainage features have hoses that empty the water directly into your drain throughout the day.

Energy efficiency

Dehumidifiers are energy-hungry machines, especially if you leave them running throughout the day. Whole home dehumidifiers typically use between 300 to 700 watts per hour. It's best only to run yours a few hours a day to avoid high energy bills. If you believe you'll need to run your dehumidifier often, consider buying an Energy Star-rated machine, as they use less energy and can reduce the impact on your electric bills.


If you spend a lot of time in your basement, you'll want a quiet dehumidifier. The manufacturer often lists the machine's decibel rating in its product description. Those with a decibel rating of around 50 dB are about half as loud as lawnmowers. Some have decibel ratings as low as 30 dB.

Choosing a unit with a lower decibel rating will ensure it doesn't disturb you throughout the day.


Dehumidifiers can be expensive making it a good idea to choose one backed by a warranty in case it quits working down the line. Warranties are also a good indicator of how long the manufacturer believes it will last. For example, if a dehumidifier is backed by a three-year warranty, the manufacturer is likely confident it will last at least that long before needing to be replaced.
