Buying Guide for the Best Dehumidifier For Basement With Pump
Choosing a dehumidifier for your basement, especially one with a pump, can make a big difference in creating a healthier and more comfortable environment. Dehumidifiers work by extracting excess moisture from the air, which helps prevent mold, mildew, and musty odors. When shopping for a dehumidifier with a pump, it’s important to pay attention to several key specifications to make sure you pick a model that fits the size of your basement, the typical humidity levels, and the way you want to drain collected water.Capacity (Pints per Day)The capacity tells you how much water the dehumidifier can remove from the air in a 24-hour period, measured in pints. This is crucial because basements can get very damp, and a dehumidifier with a low capacity might struggle to keep up. Small capacities (up to 30 pints) are suitable for small, mildly damp spaces. Medium capacities (30–50 pints) fit average-sized basements with moderate humidity. Large capacities (50–70 pints or more) are meant for large, very damp or wet basements. To pick the right capacity, consider the size of your basement and how humid it tends to get—you'll want a higher capacity for larger or wetter basements.
Built-in Pump and Drainage OptionsA built-in pump makes a dehumidifier much more convenient in a basement setting, as it allows the machine to push water up and out to a sink or through a window, rather than relying on gravity drainage or manual emptying. Some models have only a gravity drain, which works if you have a floor drain, while a pump lets you direct water anywhere within reach of the hose. If your basement doesn’t have a convenient floor drain, or if you want the flexibility to drain water upwards or over a distance, choosing a dehumidifier with a built-in pump is the best solution.
Coverage AreaThe coverage area indicates the maximum square footage the dehumidifier can effectively handle. If you use a dehumidifier in an area too large for its capacity, it won't remove enough moisture. Units are typically divided into small (up to 500 sq. ft.), medium (500–1,200 sq. ft.), and large (over 1,200 sq. ft.) spaces. Measure your basement and select a unit rated for at least as much space, or larger if your basement has high ceilings or gets very damp.
Humidistat and ControlsA humidistat measures the humidity and allows you to set a target humidity level. This is important for automatically keeping the air at a comfortable level without running the dehumidifier constantly. Some models offer simple dial controls, while others have digital settings and displays for more precise adjustment. Choose a model with easy-to-use controls and a clear humidistat if you want more control over your basement’s air quality.
Filtration and MaintenanceMany dehumidifiers come with filters that trap dust and particles as air passes through. Filters help keep the unit running efficiently and can improve the air quality in your basement. Check whether the filter is washable or needs regular replacement, and consider how easy it is to access for cleaning. If you want cleaner air as well as less humidity, look for units with good filtration and easy maintenance.
Noise LevelNoise level refers to how loudly the dehumidifier operates, usually measured in decibels (dB). For basement use, most people can tolerate a moderate amount of noise, but if your basement is finished or doubles as a living space, you may prefer a quieter model. Generally, noise levels under 50 dB are considered quiet, while 50–60 dB is average. Consider where you'll place the dehumidifier and whether the noise will matter to you—especially if bedrooms or living areas are nearby.
Portability and SizePortability involves the physical size of the dehumidifier and features like wheels or handles that make it easy to move. If you plan to use the dehumidifier in different areas, or if your basement has obstacles to navigate, portability is an important consideration. For those who will leave the unit in one spot, size may only matter if space is limited.
