Best Dehumidifiers For Basements – Reviews and buying guide For 2021

These days, basements are used for much more than storage. They have become multi-purpose areas that hold a lot of value for modern homeowners. Many people turn their old musty basements into finished game rooms, multimedia areas, or small studio apartments. No matter how you choose to use your basement, there’s one aspect of the space that you need to stay on top of.

Basements are notorious for being musty and humid. Because they are located under the ground, taking care of moisture is no easy task. In most cases, you can’t run external HVAC or ventilation systems to the outside of your home like you would on your ground floor. As a result, moisture can stick around and make the air feel awful down there.

It’s not just a matter of comfort either. Moisture and humidity can cause a slew of structural issues and health risks. So, how are you supposed to make your basement safe and habitable? Well, you can use a dehumidifier.

The best dehumidifier will be able to extract moisture from the air for removal. These devices are advanced pieces of equipment that are more than capable of controlling humidity levels in large basements. This results in a more comfortable living space and decreased chances of experiencing issues.

How Does a Dehumidifier Work?

The goal of a dehumidifier is to regulate moisture levels in the air. The problem with basements is that the temperature often differs dramatically from the rest of the home. This is because of the basement’s location underground and a lack of proper ventilation. That difference in temperature results in condensation and dampness. Depending on your climate, moisture issues can even result in noticeable puddles on the floor.

Dehumidification works to get rid of that moisture by working with the principles of condensation. They operate very similarly to air conditioning units. Essentially, the machine will expose the air to extreme temperatures, causing the humidity to condensate. This is done through the use of refrigerant and condenser coils. Powerful fans draw warm moist air into the unit. There, it flows through the cold condenser coils, causing the moisture to condensate and collect below. The low-humidity air then exits the unit for recirculation.

You might encounter more than one type of dehumidifiers on your search. However, most of them work on that same basic technology. It’s an effective method that has been working for several decades. While you might not be able to notice an immediate difference when you turn the machine on, you’ll be surprised by what a single machine can do in just a few hours.

 

Why Do You Need a Dehumidifier?

If you’re on the fence about whether or not you need a dehumidifier in the first place, consider all of the problems that moisture can cause in your home. Homes are built to keep excess moisture out. It’s why we have air conditioning systems and ventilation units.

High humidity levels in your basement can wreak havoc on the many structural components. Over time, moisture can damage wooden supports and make any drywall fall apart. It can also cause metal piping to corrode. All of these problems take time to happen. Unfortunately, once they become noticeable, it’s often too late. If you live in a colder environment, you also have freezing to worry about. Even a little bit of moisture on your walls or pipes can cause freeze damage in the winter.

Another common issue in basements is mildew. Bacteria and mold spores thrive in damp humid environments. Mold can quickly appear on your walls, floors, and any other smooth surface. Not only is mildew unsightly, but it can pose a serious health risk. Mildew is a common allergen that can cause complications with your respiratory system. You and your family can also experience serious skin irritation and illness. In the worst-case scenario, that moisture in your basement can lead to the growth of black mold. Black mold releases potentially fatal mycotoxin spores.

Finally, high moisture levels can cause pest infestation. Like bacteria and mildew, pests gravitate to areas with access to water. Roaches, dust mites, silverfish, earwigs, and more are attracted to the dampness in basements. They could easily spread to the rest of your home if you don’t take care of the problem quickly. On top of all that, your basement could attract rats and other rodents.

Needless to say, dehumidification is a must if you want to keep your home comfortable. Generally, it’s recommended that homeowners invest in dehumidifiers anytime the humidity levels in their basement reaches 50 percent. Though, you can still use a machine if humidity is a bit lower. It’s all about what makes your space comfortable. You can use a simple hygrometer to test humidity levels and see what kinds of equipment your space will need.

 

Features to Look for

When you’re shopping for the right dehumidifier, there’s a lot of things to consider. You need to think about the size of your space and what the current humidity levels are. From there, you can narrow down your search and look for the following features.

Good Coverage

First and foremost, you need a machine that can handle your space. Basements tend to be expansive, so units with a large capacity are always recommended. Manufacturers will include square footage ratings on their equipment to give you a better idea of what its capable of.

High capacity dehumidifiers should also have good CFM ratings. The CFM measurement refers to the velocity of air that flows in and out of the space. A higher CFM rating means that the machine is capable of treating a lot of humid air at one time, which is great if you have a big space.

Appropriate Drainage System

Next, you should think about the drainage system. As dehumidifiers run, condensed water needs to be removed from the machine. There are a few ways to handle this. The easiest is with water pump and drain hose. This is great if you have a floor drain in your basement or access to a sink. The pump will move the water from the collection area automatically, ensuring that you can run the machine around the clock without any issues.

Another option is a collection bucket. This type of dehumidifier is ideal if you don’t have any plumbing in your basement. Basically, the water will collect in a storage container for disposal. While these machines add a bit more versatility when it comes to placement, they need to be emptied regularly. So, you’ll have to stay on top of the water levels or invest in a unit that will automatically turn off when it has a full bucket.

Automatic Features

Some of the best dehumidifiers have a built-in humidistat or hygrometer. They will automatically monitor the relative humidity in the space and adjust accordingly. It’s kind of like a standard air conditioner. The data these systems collect ensure that the space is always comfortable. Plus, you can set the humidity control to a setting that you like.

Other automatic features you can get include restart and shutoff. With auto restart, you can rest easy knowing that your machine is always working. If you ever experience a power outage, the unit will turn back on after power is restored so that it can continue adjusting humidity levels. With an automatic shutoff system, the equipment will stop running once the water tank is full. This can help you avoid messes and leaks.

Size of Water Tank

If you choose to go with a dehumidifying machine with a bucket or tank, you’ll need to consider the amount of water it can hold. Units with a higher capacity can hold upwards of 70 pints of moisture. Typically, this is more than enough for treating large rooms throughout the day.

ACH Rating

Some basements are going to be damper than others. As such, there’s no one-size-fits-all machine that will work for everyone. The ACH rating represents a dehumidifier’s efficiency based on moisture levels in the air. ACH stands for air changes per hour. Usually, you’ll find ACH rating between 3 and 6.

With an ACH of 3, you can treat a moderately damp basement with humidity levels around 60 to 70 percent. Once you get past 70 percent, you will need a machine with an ACH of 4. If your hygrometer shows that humidity is between 80 and 90 percent, you’ll need ACH 5 equipment for efficient moisture removal. Finally, ACH 6 is the most powerful. These machines can take care of spaces with 100 percent humidity.

Operating Temperatures

Contrary to popular belief, humidity doesn’t just affect regions with tropical climates. You can experience high humidity levels even if the room temperature is near freezing. If that’s the case, you need to make sure that your dehumidifier is capable of operating at those low temperatures. Several options on the market can work efficiently in environments as cold as 33 degrees Fahrenheit. Typically, they will have automatic defrosting features to make sure that the condensing coil doesn’t get frozen.

User-Friendly Control Panel

To make the most out of your investment, go with a device that has an intuitive control panel. It’s good to have options when it comes to performance. Detailed controls will let you manipulate fan speeds and humidity levels. Depending on the particular product you choose, you may also be able to see when you need to clean out the air filter or empty out the water tank. Go with something that has a clear digital readout if simplicity is your top priority.

Conclusion

The best dehumidifier can transform your basement. It’ll turn musty old spaces into areas that you’ll want to utilize. Take some time when you’re selecting the right machine for your needs. This is a big investment that will keep your home protected while providing you with all-day comfort. Just keep your needs and the needs of your basement in mind to find the perfect model.
