8 Best Dehumidifiers to Keep Any Size Room Comfortable 2021


Enduring wet weather is bad enough, but dealing with a damp house is unbearable. Along with interrupting sleep and generally feeling gross, this excess humidity can lead to a buildup of allergenic mold and musty smells in your home. That’s where a dehumidifier comes in. The humble device isn’t as exciting as some other home improvements, but it can have a huge impact on your quality of life.

A dehumidifier removes excess moisture from the air inside your home, which can be especially humid in the summer. It can make it easier to fall asleep, prevent indoor air quality issues, keep musty odors away, keep bugs away, and just help you feel more comfortable overall.

Relative humidity should be between 30% and 50% during the warmer months and between 30% and 40% during the colder months for maximum comfort, according to the American Society of Heating, Refrigerating and Air Conditioning Engineers. Anything above will be too heavy, making it difficult to unwind.

Higher humidity can also lead to health issues: mold thrives at 60 percent relative humidity and higher, according to the Environmental Protection Agency (EPA), which recommends the use of dehumidifiers in particularly humid spaces.

How to choose the best dehumidifier

Understand your space. A dehumidifier’s capacity is usually measured in pints per 24 hours, according to the EPA’s Energy Star program, and this figure is crucial in finding the right model. Two factors influence the capacity you will need: the size of the room and the relative humidity. Most small to medium sized rooms need 20-30 pints, while large rooms probably need 30-40 or more. Exceptionally damp or wet spaces will need even more. (Energy Star has a helpful chart explaining the proper capacity.)

Think about energy consumption. Many dehumidifiers use a lot of energy, which means they will cost you on your energy bill. To reduce operating expenses, look for models that are Energy Star certified, which means they are nearly 15% more efficient than other options.

Go for the right extras. You can certainly plug in your dehumidifier and call it a day, but a few upgrades can make the experience much more convenient. Most models allow you to attach a drain hose if you don’t want to manually empty the unit every day, but you will need a unit with a pump if you want to send the water down a sink. Automatic humidistats monitor relative humidity and turn off the dehumidifier when the desired level is reached. And filter indicators remind you when to change your filter.

Now that you’ve mastered the basics, you’re ready to choose the right model for your home. Ahead, shop the top rated dehumidifiers you can find online right now.
