Ah, the basement—a hidden treasure trove of memories, storage, and perhaps a secret lair. But beneath that seemingly common space is a battleground against humidity forces. Yes, that’s right, excessive moisture lurking in your basement can wreak havoc on your belongings, health, and even your home’s structural integrity. Fear not, for we bring you the ultimate superhero in this quest—the high-efficiency dehumidifier for your basement.

Protecting your house and valuables from the harmful effects of excess humidity is integral to maintaining your home. For instance, high humidity in your basement can lead to the proliferation of rust and corrosion, which can damage your tools or electronics. Humid spaces also encourage bacteria, mold, and mildew to grow, which can result in foul odors and cause serious respiratory issues.

Most of us have been in a damp, cold basement at some point. And while a wet basement is often an unappealing place to be, it also has several health risks. A moist, damp basement encourages mold and bacterial growth and attracts rodents, roaches, and other pests. Dust mites also thrive in humid conditions, especially if they’re warm.

A high-efficiency basement dehumidifier works to remove excess moisture from the air. If your home or basement humidity is above 50%, investing in a high-efficiency dehumidifier will protect your home from damage.

How Do High Efficiency Dehumidifiers Work?

A dehumidifier works like an air conditioner–like a vacuum, it pulls air from your home. It then removes moisture from the air and pumps the air back into your home. Typically, a dehumidifier unit uses a desiccant material like silica, a cooled metal plate, or a coil to remove water from the air. However, whole-house teams use a pump to force air through your home. The following section goes into detail on how each dehumidifier type works.

What Should You Look for When Buying a Dehumidifier for Basement?

To make sure that you remove enough moisture from the air in your basement, there are a few key features to look for as you shop for an efficient dehumidifier.


You’ll need to ensure your humidifier is suitable for the size of your basement to be effective. Most listings will say what room size the dehumidifier is designed for. Buying a dehumidifier that works in a room more significant than your basement is a good idea. However, buying one designed for a smaller space is unlikely to be very effective.

Collection Capacity

Most dehumidifiers have a tank that collects water from the air, and this tank will need to be emptied periodically. Buying one with a larger tank, you’ll need to open it less frequently, but some dehumidifiers with larger tanks tend to be more expensive. If you forget to empty a tank, you run the risk of it overflowing. If this concerns you, you may want to consider a dehumidifier that includes an indicator–this is usually in the form of a light that will turn on as the tank comes close to capacity. Some units even have an automatic shutoff function, turning them off if the tank empties.

Energy Efficiency

Some dehumidifiers are more efficient than others. If you want to save on running costs, look for one certified as energy efficient. These units may cost a little more upfront, but their lower energy costs will compensate for the price difference after you use it for a while.

Humidity Controls

Many dehumidifiers allow you to set your level of desired humidity. This lets you avoid overly dry air. Usually, you want your home to have a relative humidity of 40% to 50%, and a dehumidifier enables you to set your desired humidity level and let the machine maintain it.

Defrosting Capabilities

If you live in a colder climate, you run the risk of a refrigerant dehumidifier freezing. Because the machine already chills the internal metal plate or coil, it can freeze even when your home temperature is above freezing. A unit that automatically defrosts will work more effectively. And because frozen coils can cause permanent damage to a dehumidifier, they are often worth the extra expense, significantly if your basement regularly drops below 65 degrees.

What Dehumidifier Types Are Available?

High-efficiency dehumidifiers all have the same central purpose: they remove moisture from the air. However, depending on your unique needs, one type may be better. Dehumidifiers come in three main types: desiccant, refrigerant, and whole house.

Desiccant Dehumidifiers

Desiccant dehumidifiers extract moisture from the air using a substance that absorbs water. They slow-rotate a wheel made of silica or similar material in front of the incoming air. The humidity condenses due to warm air inside the machine and falls into a collection tank. Even though some desiccant dehumidifiers include replaceable desiccant cartridges, they are less energy-efficient than other varieties. Mini dehumidifiers are more affordable, portable versions of larger, more permanent desiccant dehumidifiers that dry up small spaces like closets or basements.

Refrigerant Dehumidifiers

As the name suggests, a refrigerant dehumidifier works similarly to a refrigerator. The unit pulls air from your home over a chilled metal plate. As the air passes over the plate, it causes moisture to condense and collect. These machines are more energy-efficient than desiccant dehumidifiers. However, they may be less efficient if your basement becomes very cold. Even at cooler indoor temperatures, the metal plate may freeze, which makes it difficult or impossible for the unit to pull moisture from the air.

Whole-House Dehumidifiers

These dehumidifiers can’t be confined only to the basement. But if you’re experiencing issues with high humidity in other areas of your home, they may be worth the investment. A whole-house dehumidifier is essentially a pressurized fan. It’s placed in the attic and quietly and continuously pumps air through a grille in the ceiling. The new air pushes out existing damp air along with moisture. These units usually will have a higher installation cost, but they also are cheaper to run. A whole-house dehumidifier usually connects to your home’s existing ventilation system, so you probably will need a professional to install it after purchase.

Why Is the Basement a Good Place for a Dehumidifier?

Unless you choose a whole house system, you’ll need to choose a place in your home to put your dehumidifier. More often than not, the basement is an ideal place to put it. Here’s why.

  • Surrounding Soil Causes Extra MoistureEspecially if you live in an area with a low water table, your basement is especially likely to be affected by surrounding soil moisture. This means the basement is at extra risk for mold and mildew buildup. Of course, other areas of your home may get exposed to water–hot showers release some moisture into the air, increasing humidity. However, these increases are temporary, and many bathrooms have ventilation fans that prevent moisture from lingering and causing mold and other issues. Your basement is constantly surrounded by damp soil, making it more crucial to place a dehumidifier there.
  • Basement Water Damage Is Especially Likely to Damage Your Home’s StructureContinued basement moisture can cause crawlspace mold growth and seriously damage your home’s structure. This is especially true if you have a wood-based foundation. Constant humidity can eventually cause a wood-based foundation to rot away, which leads to dangerous and costly damage.
  • Running Noise Is Unlikely to Be IssueMost dehumidifiers are very quiet to run. However, this can become an issue if you’re sensitive to noise or have an unusually loud unit. Since most people don’t spend much time in the basement, a dehumidifier placed here is unlikely to disturb you.

Final Thoughts

Because extra humidity can cause severe issues to your home and your health, many homeowners see dehumidifiers as wise investments. And luckily, there are many models to choose from. Whether you want a basic model or a highly efficient unit with multiple controls, a basement dehumidifier will help you avoid moisture-related issues in any season. Remember to research potential models and ensure they are suitable for your basement size and temperature, and you’ll be well on your way to healthier, less humid air.
