The right amount of humidity is critical to maintaining comfort levels inside your home. Too much or too little moisture can also cause problems that damage your home. So it is important to keep the humidity level at a certain level.

When used properly, a portable dehumidifier will remove excess moisture from spaces inside your home. Depending on the sources of humidity, it will be more appropriate to place your dehumidifier in one location versus another.

The Best Placement for Your Dehumidifier

Generally, there are three factors to consider when figuring out the best place to put your dehumidifier:

  1. Source of humidity. Where is the humidity coming from? Is it coming from an internal source such as a shower, or an oven? Or is it coming from an external source such as a window or door?
  2. Size of the room. How big is the room that you need to dehumidify? Is it a large space such as a living room or basement? Or is it a small area such as a bathroom?
  3. Restrictions to airflow. Are there any objects nearby that will block airflow in/out of the dehumidifier?

The first thing to do is to ensure that you place your portable dehumidifier near the source of the moisture. This will allow it to work most efficiently since it can remove humidity before it has a chance to infiltrate other areas.

The size of the room also plays a factor in your dehumidifier placement. If you are dehumidifying a large room, then you will need to place the dehumidifier in a central location in order to get maximum coverage. For a small room, this may not matter as much since there is less area to cover.

To function properly, dehumidifiers require clearance from nearby objects to maintain airflow. This means that you do not want to have your dehumidifier too close to furniture, a wall, or other objects. If the airflow is restricted, the dehumidifier won’t function efficiently.

Placing the dehumidifier near the center of the room is always a good place to start – you will have good room coverage and unobstructed airflow.

One thing to keep in mind is that dehumidifiers contain a tank that gradually fills up with water. So don’t place a dehumidifier near any electronics such as power strips, or on something that you don’t want to get wet.It is rare that a dehumidifier leaks on the ground – but you want to make sure that nothing gets damaged in case it does.

You will also need to eventually empty the dehumidifier’s tank. The tank fills with water when it removes humidity from the air in your home. So be sure that the tank is accessible for emptying when it gets full. Alternatively, some dehumidifiers allow you to connect a hose to drain the tank automatically.

Remember that a dehumidifier is a piece of machinery, so you want to keep it clean. Keep your dehumidifier clean and away from sources of dirt and dust. A clean dehumidifier will function properly and efficiently.

What Room Should You Place Your Dehumidifier in?

Generally, places where you find moisture are the best places to put a dehumidifier. Spaces such as bathrooms, basements, kitchens, and crawl spaces are all locations where excess moisture can be present.

If you are unsure of the humidity levels inside your home, it will be helpful to use a device that can give you a reading of humidity levels. Using a hygrometer is an excellent way to get an accurate measurement of humidity levels inside your home.

Once you have discovered the source of humidity in your home, then it is important to isolate it. You don’t want the humidity to creep into other spaces and potentially cause more damage.

Be sure to close all the doors to the room where the humidity is present. You want to isolate the humidity in that one room, so you can remove it using a dehumidifier. Make sure to close all windows as well – you don’t need extra humidity coming in from outside.

Dehumidifier Placement for Bathrooms

Long hot showers will quickly raise the humidity inside your bathroom. If you have ever taken a hot steamy shower, then you have seen that the steam in the air is actually small water droplets. This condensation means that the humidity level is 100% because the air is unable to hold all of the moisture in the bathroom.

Condensation provides a perfect habitat for mold and mildew to grow inside your bathroom. Additionally, condensation causes paint to peel and wood to rot.

If you have ever noticed mold, mildew, or condensation, then placing a dehumidifier in your bathroom is a smart move to combat high humidity. Ideally, you will want to run the dehumidifier right after you take a bath or shower. Running the dehumidifier for about 20 minutes after a shower is usually long enough to remove excess humidity from the air.

Placement of a dehumidifier in a small room such as a bathroom is always tricky. There is not much space to put a dehumidifier on the floor. Fortunately, since the bathroom is a small room, you also can use a small dehumidifier. Some dehumidifiers are small enough to put on a shelf or the top of the toilet bowl.

Dehumidifier Placement for Crawl Spaces

Ceilings and crawl spaces are the most unassuming places that can contain the highest amounts of humidity.

High humidity in crawl spaces usually occurs during the cold months, when outside temperatures are colder than inside temperatures. As the warm, moist air infiltrates your cold attic, condensation forms. This is because cold air can not hold as much moisture as warm air, so the humidity levels rise. Even worse, leaky pipes or inadequate insulation can contribute to far higher humidity levels in your crawl space.

Because of the cramped spaces, crawl space dehumidifiers are usually more compact than other types of dehumidifiers. Crawl space dehumidifiers also need to have a stronger fan to ensure that dry air circulates around the tight spaces and around corners. For these reasons, it is important to use the proper type of dehumidifier if you are going to be putting it in your crawl space.

When placing a dehumidifier in a crawl space, it is important to ensure that it is centrally located with adequate clearance. You want to make sure that the dehumidifier is allowed to exchange air with the greatest space possible. Depending on the size of your crawl space, it may be helpful to use a fan to circulate air around the crawl space. Circulating the air in tight spaces will aid in dehumidification.

If your dehumidifier can not continuously drain, you will need to access the dehumidifier regularly to empty its tank. So make sure that your dehumidifier is easily accessible if you are using its tank to collect water.

Dehumidifier Placement for Kitchens

Kitchens are a constant source of humidity inside a home. While the kitchen sink can certainly bring humidity, other sources such as dishwashers, refrigerators, and cooking can bring unwanted humidity as well.

Using a dehumidifier in your kitchen is all about tracking down the source of humidity so you can target that area. For instance, if the source of humidity is the kitchen sink, then placing a small dehumidifier next to the sink is optimal. Or if your kitchen gets humid when you cook, then using a dehumidifier near the stove will help keep your air dry.

No matter where you put the dehumidifier, remember that maintaining airflow is important. So you don’t want to place it in a corner or in a tight space.

Dehumidifier Placement for Basements

High humidity in basements is a common occurrence. This is because basements are underground – so they are vulnerable to water seeping in through the walls. Most basements also lack adequate ventilation. Also, moisture-containing appliances such as washers and water heaters are often located in basements. Humidity can build up quickly, especially when moist air is not allowed to ventilate to the outside.

Fortunately, a dehumidifier works well for most people to keep excess humidity out of their basement. Since most basements are small, enclosed spaces, it is usually not hard to manage the humidity inside the space.

Better yet, since many basements already have plumbing for their washing machines, you can drain a dehumidifier’s tank directly into the basement drain. This is important if you need your dehumidifier to continuously operate.

The basement is also a good place to put a dehumidifier because it is a discreet place that most visitors won’t see or hear. If you have a large basement, be sure to make sure that your dehumidifier’s rating is enough to serve the area of your basement. Be sure that you place the dehumidifier in a central location for maximum efficiency.

Dehumidifier Placement for Living Rooms

Living rooms are tricky when it comes to dehumidifier placement. Living rooms are usually the biggest room in a house, so ideally you will want the dehumidifier near the center of the room. However, a large portable dehumidifier in the center of the living room takes up a lot of valuable space.

If you are using your dehumidifier in your living room, then remember to find the source of humidity and place your dehumidifier close to it. A common source of humidity in living rooms is the front door. Humid outside air leaks in from outside and brings moisture into your living area. If this is the case, then placing the dehumidifier near the front door will be most effective.

Above all, make sure you get a dehumidifier that is large enough to work effectively in your living room. The small dehumidifier that you use in your bathroom might not be strong enough to rid your entire living room of moisture.

Dehumidifier Placement for Bedrooms

One of the most important reasons for maintaining the correct humidity levels in your bedroom is your health. Having proper humidity levels helps you sleep better and will reduce the amount of allergens present.

Bedrooms are not usually prone to high humidity. However, leaky windows can change all that. Cracks around windows allow moist outside air to infiltrate your bedroom, raising the humidity. Houseplants can also contribute to humidity in the bedroom.

Because of the relative small size of bedrooms, the most important factor for dehumidifier placement is to ensure that it gets sufficient airflow. You don’t want to put your dehumidifier in a corner.

Final Thoughts

Figuring out where to place your dehumidifier is not a hard task, but it is crucial for proper dehumidification of your home.

Above all, remember to isolate the humidity sources, and get a properly sized dehumidifier for the room that you are using it in. When it’s time to start up your dehumidifier, make sure that it has unobstructed airflow for maximum room coverage.
