How Does a Dehumidifier Work?

A dehumidifier is an electric gadget that removes moisture from the air. It is a bit like a vacuum cleaner that reduces the moisture content in the air of a room. This machine works in one of two ways—either by refrigeration or by absorption. However, the overall job is the same for both.

It uses a fan to suck air from the room at one end over the refrigerated coil. This coil helps remove the moisture from the air and collects the water in a tank. The dry air is then blown outside back again. You need to empty the tank filled with the collected moisture from time to time.

A dehumidifier for a basement is the same as any regular dehumidifier, except that it has a certain feature that makes it more efficient in the basement. Usually, dehumidifiers only equipped to work above ground sometimes aren’t that well-equipped to handle the high moisture content of a basement.

When to Use a Dehumidifier in the Basement?

If you’ve ever described your basement with words like sticky, cold, soggy, damp, or smelly, then it is time to put a dehumidifier there. Too much moisture content in an enclosed place makes the air damp and musty smelling.

Experts say that the relative humidity in a basement should not be higher than 55 percent. Because when the humidity exceeds this amount, it breeds mold, mildew, dust mites, and other allergens, causing many health problems.

If you’ve been suffering from frequent allergies or sneezing for some time, maybe there is a problem of too much humidity in the house.

Below is a list of several points that are caused due to excess moisture in basements. If you see any or multiple of them happening, you have to buy a dehumidifier for the cold basement.

  • Tangibly Damp Feeling

You can feel and smell whenever there is not much moisture in the air. This change in the air can readily be felt when you walk into the basement from above ground. So, if the basement feels damp on the skin, it can be assumed that the humidity there is higher than it should be.

  • A Strong and Musty Odor

High moisture in places like the basement intensifies all kinds of odors. Since mold and mildew growth increases in humid conditions, they also produce a musty smell. You can easily identify the presence of mold in the air and on the wall due to the presence of little dark spots.

  • Condensation

Another good symptom of high humidity in the basement is condensation on various cold surfaces. You’ll notice the basement windows looking foggy due to this contestation. If the situation gets worse, you might see such condensation on walls and floors as well.

  • Rot and Decay

Rot can manifest in various ways. But the most prominent one is that of wood. Whenever you see any wooden surface appearing profusely cracked, it means the wood had started rotting due to exposure to moisture for a long time.

  • Peeled-Off Paint

High moisture content in the air also loosens the glue between the paint and the wall surface. The paint starts to peel, blister or crack when the air is humid for a long time. Once the place has been dehumidified, the paint has to be removed. It is also imperative to repaint the wall also

Benefits of a Dehumidifier

There are some noteworthy factors you need to put in mind before purchasing the best basement dehumidifier. Following are some of the major benefits a dehumidifier is supposed to provide:

  • Humidity Maintenance

A good dehumidifier in the basement will help maintain an ideal humidity level. When you properly install it, the machine will work to improve the overall air quality of that space. Since a basement serves as a base for the entire house, its good maintenance eventually leads to better maintenance of the home.

  • Reduction of Allergens

Molds and mildews are the major allergens in any home, and their growth in the basement will lead to many health problems like allergies. Since they tend to grow mostly in humid conditions, a dehumidifier will help stop their growth by creating a drier environment.

  • Odor Elimination

Good riddance of mold and mildew also leads to the elimination of a musty smell in the air that is created by those allergens. Besides, since the air is less humid, other types of smells cannot intensify either.

  • Protection of Family Health

Installing a high-performance dehumidifier for cold temperatures help alleviate allergy since it creates a hostile environment for mold and mildew growth. These molds produce microscopic spores into the air, triggering many health problems.

Effective dehumidifying not only make the space more comfortable but also protects the family’s health with its drying power.

  • Protects Your Belongings

Basements are used by many as a storage place for various furniture and other belongings like clothes, machines, and other utensils. A basement filled with humid air, molds, mildews, and dust mites leads to deterioration of both the structural elements like the wood and your belongings.

When the basement is clean without excessive moisture content with a cold dehumidifier, your belongings are protected and saved from the vulnerable effects of moisture.

Best Dehumidifier for Cold Basement

Basement Dehumidifier Buying Guide

Now that you know how a dehumidifier improves your life in the house, it is time to look for the best dehumidifier for the basement that provides those values. If the sheer number of options out there in the market confuses you, then take help from this actionable guide below:

  • High-Performance Dehumidifier

The main reason for purchasing a dehumidifier is its capacity for moisture removal. And so, the first thing to look for in the machine is how good it is at its job.

It is important to note that all home dehumidifiers might not work well in a cold and damp basement. And the reason is, a home dehumidifier is made for removing mid-level moisture from the home.

However, the basement is a completely different game. It is below the ground, enclosed, dark, and an extremely moist space. And normal dehumidifying machines will have a very hard time doing a satisfactory job there.

So, you need to specifically mention where the machine will be used before purchasing. Get a dehumidifier that’s specifically built for this job in the basement.

  • Capacity of the Dehumidifier

Most times, a dehumidifier is ranked based on its capacity to remove moisture from a place. It is rated in terms of the floor area and denoted by pints. In other words, the amount of moisture the dehumidifier can remove from a given space or area.

To bring the point home, let’s consider this example. Suppose a dehumidifier that can remove 22 to 25 pints of moisture per day will work best in a basement of area 2000 sq. ft.

However, the amount of water removed by a dehumidifier can vary based on the humidity and the area of the basement. The more powerful the dehumidifier is, the greater its capacity will be.

While purchasing the machine, consider the floor area rating also. Measure the floor area of the basement you have and buy according to that. Most dehumidifiers have a rating of 4500 sq. feet.

  • Defrosting

Usually, the basements are colder than any other part of a home, and that’s why low-temperature dehumidifiers need additional features to run efficiently. In a cold environment, the compressor in the dehumidifier runs the risk of frosting. Such frost buildup on the coil is detrimental to the machine’s efficiency.

So, consideration must be taken to get a dehumidifier that is equipped with a defrost mode which will monitor the frost buildup in it and shut off the machine upon necessity. This feature lets the frosting melt and gather in the tank.

Some modern dehumidifiers don’t even need a separate defrost mode. They can operate at a very low temperature, all the way down to 41°F.

  • Automatic Draining

This one is an important feature to have in a basement dehumidifier. All dehumidifiers collect the water from the air in a tank all the time. After some time, when the tank becomes full, it might spill onto the floor. And it is not expected that you’ll go into the basement multiple times a day to empty the tank.

So you need an automatic drainage feature with your dehumidifier that can pipe water to a drain in the basement. There are many which can be connected to a hose allowing the condensed water to divert directly into the floor drain.

If there is no floor drain in the basement, look for a dehumidifier that can pump the water up through the window or to some high drain.

  • Bigger Tank Size

This one can also be understood from the problems discussed in the previous point. The water tank in the dehumidifier is important because the water could spill after a very short period.

If the water tank is small, you’ll need to empty it continuously; this will directly impact the downtime of the dehumidifier since it won’t run during those times.

Suppose you buy a high-capacity dehumidifier with a small water tank of 10 pints only, then you’ll need to empty it at least five times daily. And for that, you’ll have to shut off the dehumidifier five times. This downtime will considerably affect the efficiency of the machine.

On the other hand, if the tank size is bigger, then you’ll need to empty it less often, and the downtime will also be less, increasing the efficiency. But the best option is to look for an automatic draining system mentioned in the previous point. In that case, there won’t be any downtime due to emptying the tank.

  • Dehumidifier Type

There are mainly two types of the dehumidifier and choosing either one will depend on the ambient air temperature of the basement.

For basements with consistently lower temperatures under 41°F, it is suggested that you use a desiccant dehumidifier type. And for warmer basements compressor dehumidifier works fine. Although both types do the same job of removing excess moisture from the air, each has its own specialties. 

The compressor type is basically the default dehumidifier technology in the market. It uses a condensation mechanism to extract water by passing it over a refrigerated coil. Condensation occurs on the cold surface, and the water is collected in a tank. The dryer air is then released back into the room.

Desiccant dehumidifiers work more like a sponge or silica gel. It uses a desiccant material that absorbs moisture from the humid air, like silica gel. The major benefit of this type is that it works equally well in both warm and cold ambient temperatures. But they are way more expensive than compressor types.

  • User-Friendly Controls

Any machine’s value increases with how easily you can use and control it. Electronic and easy controlling of a dehumidifier will let you select different humidity levels like normal, dry, or very dry. There are also digital controls available on some modern items that even let you specify the humidity percentage.

  • Auto-Restart

In case of any temporary power outage, a dehumidifier equipped with this feature helps you restart the machine afterward. It also comes in real handy whenever you’re away from home for a long time. This function turns on the machine retaining all the previously inputted settings.

  • Timer

With this feature, you can turn the dehumidifier on or off even when you’re not at home. It also saves money by turning it on during the hour of cheaper off-peak electricity rates.

  • Clean Filter Alert

There is a filter in the dehumidifier that cleans the air when air flows through it. However, when it becomes dirty, the efficiency of the machine takes a hit. You wouldn’t know how much the filter has become dirty unless you check it for yourself from time to time.

A clean filter alert automatically lets you know when to clean it, for it reduces the efficiency of the dehumidifier. Usually, there is an indicator light that tells you it is time to clean the filter.

  • Quiet Operation

Most dehumidifiers have a fan that makes a lot of noise. Although a higher fan speed is going to offer better performance, the high noise it brings can make some people really irritated.

The best low-temperature dehumidifier is that which runs less than 45dB even with a high fan speed. Some dehumidifiers tell you the fans’ noise level, and you can purchase those with ratings under 45dB.

Frequently Asked Questions

1. How do I maintain my dehumidifier?

Humidifier maintenance is necessary if you want to get benefitted from its service for many years. The best way to take care of it is to perform regular checkups by following the manufacturer’s tips in the user manual. Still, some of the most important points of maintenance are:

  • Turn off and unplug before maintenance
  • Clean the filter when they get dirty
  • Keep the basement airtight as much as possible
  • Drain the water tank after each use
  • Clean the machine and the water reservoir regularly

2. How do I make sure the basement is ready for a dehumidifier?

There are few considerations you should check before installing a dehumidifier in the basements, and those include:

  • Create proper sealing and provide an enclosed space for the machine to operate in. If outside air keeps entering, it will absolutely diminish its efficiency.
  • Remove the perpetual source of humidity like standing water in the basement. It will just keep sourcing moisture in the air no matter how much the dehumidifier removes them.

3. What is the ideal humidity level in a basement?

When the dampness in the basement air is more than 70%, the moist air is felt easily. This high moisture content creates many problems, including damage to wooden things, clothes, formation of mold, mildew, and mites.

That is why in a basement, the ideal humidity level should be below 50% to eliminate all these problems.

4. Where should I place the basement humidifier?

The best location for a humidifier is the middle of the basement so that it can intake and distribute air evenly on all sides. This position gives the machine enough space for air circulation, reducing energy consumption. It also increases the efficiency of the dehumidifier.

5. Do humidifiers kill mold?

Although many people believe it does, a humidifier doesn’t actually kill mold. However, it helps inhibit the growth of mold and mildews by lessening the humidity level in the room.

Our Verdict

Although we’ve reviewed some of the best basement dehumidifiers on the market, we have preferences among these as well. Our verdict goes to TOSOT’s 50-pint dehumidifier mainly due to its built-in pump which is compatible with any type of drain hose.

We should also give props to the Yaufey dehumidifiers for their beautiful design, small footprint, and ease of operation.

Final Words

A dehumidifier is a handy appliance in balancing humidity levels in an enclosed space. If your house has an overly humid basement, it will eventually damage wooden materials by rotting them. The best dehumidifier for cold basements helps solve the complication to a great extent.
