Top Basement Dehumidifiers | Buying Guide

Basements are notorious for not only being dark but humid. When this part of your home or business is humid, it can cause mold growth, musty odor, and even structural damage. Overall, a dank basement can be both unpleasant to live in and potentially harmful to your house.

Why do basements get so humid? Three main reasons: excess groundwater, humid outdoor air/soil, or interior moisture. To remedy the situation quickly and affordably, consider investing in dehumidifier.

Why It’s Important to Get A Basement Dehumidifier

A basement dehumidifier will help you manage problems related to basement moisture and condensation. Once your basement humidity levels rise to more than 50%, your basement is at risk. Dehumidifiers can be great solutions to keep humidity levels low in a well-sealed basement.

With a dehumidifier, you should expect an improvement in indoor air quality and smell in your home!

About Unit Size

The size of your basement and its default humidity levels are two things to consider when shopping for a dehumidifier. Unit sizes are based upon the amount of moisture that they’re able to eliminate in a day. Calculate the size of your basement before you commit to buying a dehumidifier.

Basements that are bigger and wetter require more powerful dehumidifiers. For instance, if your basement measures over a thousand square feet and is very damp, then you’ll want to purchase something like a 50 pint dehumidifier, which is a large unit. A medium-sized dehumidifier is powerful enough to remove 25 to 35 pints of moisture for rooms around 700 square feet, while a small unit can handle 15 to 20 pints of moisture.
