Using a dehumidifier is the most efficient way to combat excess moisture in the air. Although it’s easy to control the humidity in a small room, basement dehumidification can be tricky because basements are spacious and often drafty.
However, with the right dehumidifier, you can reduce your basement’s humidity level and prevent damaging mold and mildew.

Dehumidifier for the Basement Buying Guide
Prolonged high humidity can wreak havoc on your basement. However, a dehumidifier can prevent the damaging effects of humid conditions. To choose a dehumidifier that can handle the size of your basement, there are a number of features to consider, such as the reservoir’s capacity and the control panel’s configuration.
Let us point you in the right direction with this buying guide, so you can find a dehumidifier that can get the job done.
Since the sole purpose of a dehumidifier is to extract moisture from the air, the first feature to examine is how much water it can remove. Every manufacturer will list the amount of water a dehumidifier can draw from the air per day in the machine’s specs.
For efficient basement dehumidification, you’ll need a dehumidifier that can draw at least 20 pints of moisture from the air every 24 hours.
To adjust its water removal ability, you may be able to change the dehumidifier’s fan speed, keeping it on high when the humidity level is elevated and low when you simply need to maintain the current relative humidity.
Going hand-in-hand with a dehumidifier’s water-removal capability is its tank capacity. The more water the reservoir can hold, the less often you must empty the tank. Some models are equipped with a drainage port that continuously empties the collected water, and many dehumidifiers have a viewing window that lets you monitor the water level.
Even though you may need your dehumidifier to run day and night, there will be times when you won’t be home to tend to the reservoir. That’s why it’s important to use a dehumidifier with an auto-shutoff mechanism.
This feature instantly turns off the machine when the tank is full to prevent water leaks and motor burnout. If you don’t want the dehumidifier to run constantly, choose one with a timer function.
The layout of the control panel determines how easy it is to change the dehumidifier’s settings. Out of all the configurations, touch panels are the easiest and sleekest. However, your main objective should be to make sure that the controls are clearly labeled or illustrated.
Many models have a digital display that shows the room’s relative humidity as well as indicator lights that tell you when the dehumidifier needs maintenance.
It’s highly unlikely that the dehumidifier will remain stationary the entire time you own it, so choose one with a manageable weight. Usually, dehumidifiers have caster wheels and at least one handle to help you move them.
Look for double casters or wide-set wheels to achieve optimal mobility. Also, makes sure the dehumidifier can fit in the space where you want to keep it by looking at the appliance’s width, depth and height.
Almost every dehumidifier contains a filter that traps harmful particles like bacteria, mold spores and other allergens, so they won’t enter the air. However, not all filters are the same in terms of quality. Some of the best filters are constructed from an antimicrobial material, and those that are washable will save you money on replacements.
What Are the Signs of a Humid Basement?
A thorough check of your basement can reveal multiple signs of high moisture. Often, the first sign people notice is a musty odor in the air. This smell is caused by mold and mildew, which you may spot on the walls, ceilings or items you have stored in the basement.
There may also be condensation built up on the floors, walls and windows. In bad cases, this condensation turns into full-fledged puddles. Paint bubbles and yellowed stains are two other signs.
If you have carpet in the basement, you may also see areas of the carpet with deteriorated fibers.
What Causes High Humidity in a Basement?
Even though every situation is unique, there are several common issues that cause a basement to become humid. Some problems originate from inside of the home, such as plumbing leaks. Poorly ventilated dryers and inoperable stove exhaust fans can also cause high humidity.
Other sources come from outside of the home. Cracks in the foundation are one way for moisture to enter a basement. Gutters that are clogged or ground that slopes toward the home are two other culprits.
If you tend to open your basement windows in the summer to feel a breeze, you’re also letting in humid air that can lead to condensation on the basement’s floor and walls.
What Are the Consequences of Having a Humid Basement?
Muggy air is unpleasant, but excess moisture in the air can lead to more problems than just discomfort. Dust mites, mildew and mold spores thrive in damp areas. If your basement is humid, these contaminants can spread throughout the air. In turn, this can cause respiratory issues, especially in those who suffer from allergies or asthma.
Mold and mildew can also do a number on your personal belongings. When mold grows on objects like books, blankets and furniture, they are usually damaged to the point where you have to toss them. Plus, moisture can cause the walls, foundation, beams and other structural components in your basement to rot, leading to expensive repairs.
How Do Dehumidifiers Work?
Dehumidifiers are hard-working machines. The typical dehumidifier pulls the air in a basement toward its inlet via a powerful fan. Then, the dehumidifier moves the air inside of it over the condenser coils, which glean moisture from the air.
After the moisture is dropped into the dehumidifier’s collection tank, the dried air is pushed into the basement where it circulates around the room. Over time, the basement’s humidity lowers to a healthier level.
How Does the Water Drain?
Each dehumidifier is different when it comes to the draining method implemented by the manufacturer. Some models have a removable reservoir that either lifts or pulls away from the machine. To dump the water, you simply carry the reservoir to the nearest sink.
Other dehumidifiers may have a removable reservoir and a drain port. All you have to do to take advantage of the drain port is attach a hose to the port and let it hang in a sink or next to a floor drain, and the dehumidifier will drain itself.
There are also dehumidifiers that contain a pump. These models can remove the water even if the hose is vertically placed.
How Much Energy Do They Consume?
The cost of electricity can be brutal during peak seasons. However, most dehumidifiers won’t make a noticeable difference in the average home’s electricity bill. To measure how much money it takes to use a dehumidifier, you can calculate the kilowatts per hour it consumes. If you plan to run it all day and night, multiply 24 and the dehumidifier’s wattage. Then, divide the number you get by 1,000.
How Can I Determine a Dehumidifier’s Effectiveness?
Luckily, there is no math involved in figuring out how effective a dehumidifier is at removing moisture from the air. Manufacturers almost always list a dehumidifier’s moisture removal capacity in the product’s specs. The amount of water it removes is calculated in one of two ways.
One way is by calculating how much water the dehumidifier removes when the relative humidity is at 60 percent and the air temperature is at 80 degrees, which are the conditions used by the AHAM, or Association of Home Appliance Manufacturers.
The other way involves measuring how much water the machine can draw from the air when the relative humidity is at 100 percent. This calculation method tells you the dehumidifier’s water removal limit.
Since it’s highly unlikely your basement is that humid, the dehumidifier should be able to perform better than what this rating shows as long as the machine is sized correctly for the space.
