High Efficiency Basement Dehumidifiers – Consumer Reviews

Protecting your house and valuables from the harmful effects of excess humidity is an integral part of 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 things like 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 in our lives. And while a damp basement is often an unappealing place to be, it also has several health risks. A wet, damp basement encourages mold and bacterial growth, and it also attracts rodents, roaches, and other pests. Additionally, dust mites thrive in humid conditions, especially if they’re also warm.

A high-efficiency basement dehumidifier works to remove excess moisture from the air. If your home humidity (or even just basement humidity) is above 50%, investing in a high-efficiency dehumidifier is likely to improve your health and protect your home from damage.

How Do High Efficiency Dehumidifiers Work?

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

What Should You Look for When Buying a Dehumidifier?

In order 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.

  • Size

    If you want to make sure your dehumidifier will be effective, you’ll need to make sure it’s suitable for the size of your basement. Most listings will say what room size the dehumidifier is designed for. It’s okay (and often a good idea) to buy a dehumidifier that will work in a room larger than your basement. However, if you buy one designed for a smaller room, it’s unlikely to be very effective.

  • Collection Capacity

    Most dehumidifiers have a bucket or tank that collects water from the air, and this tank will need to be emptied periodically. If you buy one with a larger tank, you’ll need to empty 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 is a concern for 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, which turns them off if the tank becomes full.

  • Energy Efficiency

    Some dehumidifiers are more efficient than others. If you want to save on running costs, look for one that’s certified as energy efficient. These units may cost a little more upfront, but their lower energy costs will make up for the price difference after they’ve been used for a while.

  • Humidity Controls

    Just as you can set your desired temperature on an AC unit, 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 lets you simply set your desired level of humidity 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 internal metal plate or coil is already chilled by the machine, it can freeze even when your home temperature is well 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, especially 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 than another. Dehumidifiers come in three main types: desiccant, refrigerant, and whole house.

  • Desiccant Dehumidiers

    These dehumidifiers rely on the same technology as silica beads–they’re made with a material that absorbs water. But unlike silica packets, these machines have a way to effectively re-dry the materials once they’ve absorbed water. This allows them to remove moisture continuously, and it saves you the hassle of constantly replacing the desiccating substance.

    To remove moisture from the air in your basement, a desiccant dehumidifier uses a wheel made mostly of silica or a similar substance. The wheel turns slowly in front of the stream of incoming air from your home. This lets it remove moisture. As the wheel turns, a portion of it is hit with a stream of warm air coming from inside the machine.

    This warm air doesn’t evaporate off the air from the wheel (since this would just release moisture back into the air in your home). Instead, it caused it to condense, and it drops into a collection tank within the dehumidifier itself. Not all of these dehumidifiers use a wheel, though–in some cases, a desiccant dehumidifier may come with replaceable cartridges filled with desiccant material.

    You’ll need to periodically empty the collection tank out or replace the desiccant cartridge, but otherwise, a desiccant dehumidifier is relatively low maintenance. These units tend to be small and light, but they aren’t as energy efficient as other types.

    Additionally, you may see mini dehumidifiers as you shop–these are usually a simplified version of the more permanent desiccant dehumidifier. Most are designed to be hung in a closet or placed in small areas where moisture becomes an issue.

  • Refrigerant Dehumidiers

    As the name suggests, a refrigerant dehumidifier works similarly to the way a refrigerator does. 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, if your basement becomes very cold, they may not be as efficient. 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 it 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 Moisture

    Especially 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 be exposed to moisture–hot showers release some moisture into the air, leading to an increase in 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 Structure

    Continued basement moisture can cause growth of crawlspace mold, and it also can seriously damage your home’s structure. This is especially true if yo have a wood-based foundation. Constant moisture can eventually cause a wood-based foundation to rot away, which leads to dangerous and costly damage.

  • Running Noise Is Unlikely to Be an Issue

    Most dehumidifiers are very quiet to run. However, if you’re sensitive to noise or have an unusually loud unit, this can become an issue. Since most people don’t spend a lot of time in the basement, a dehumidifier placed here is unlikely to disturb you.

Final Thoughts

Because extra humidity can cause serious issues to both 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 right for your basement size and temperature, and you’ll be well on your way to healthier, less humid air.
