When you purchase your dehumidifier, the next step is deciding where to place a dehumidifier in your home.
Finding the perfect place for your dehumidifier is an integral part of making sure your dehumidifier works effectively in your home.
The best placement will help you bring down the relative humidity to a comfortable level.
Our guide will walk you through the process of placing your appliance in your home.
The room size places an important role in how your dehumidifier works. The larger the space, the more central your dehumidifier needs to be. For example, if you are placing the dehumidifier in a small room such as a bedroom, then you can place it in a corner or near a wall.
However, if you are placing the dehumidifier in a main room such as a living room or family room, then we recommend placing it away from the wall and corners, towards the middle of the room. You need to make sure that the dehumidifier can pull air in from all areas of the room in order to work most effectively.
Source of Humidity
You need to consider where the humidity is coming from in your home. Is it coming from the environment and relative humidity outdoors? Or is it coming from something inside your home, such as your shower or your heater?
You want to set your dehumidifier near the source of humidity in your home. If it is external, placing it near a window or near the middle of the room facing your door is the best option. If it is internal, you want to place it near the shower or the heater.
Restrictions to Airflow
Wherever you place your dehumidifier, you want to make sure that there are no restrictions to airflow. This means that the dehumidifier needs to be able to effectively pull in air using its internal fan. Ensure that all furniture and other objects are approximately two feet away from the dehumidifier and not blocking the airflow path (if possible).
Where Should You Place Your Dehumidifiers?
If you plan to place your dehumidifier in the basement, then we recommend making sure that it is not put in a moist area. Basements sometimes have damp floors or moist carpet, and it is important that the dehumidifier is in a dry space.
If you do have damp floors or moist carpet, place a small table or another piece of furniture in the room and put the dehumidifier on top of it.
If you are using a dehumidifier to reduce humidity levels in your crawl space, we recommend placing the unit in the middle of the space. There isn’t always a lot of airflow in a crawl space, and if you put the unit next to the wall, you won’t be able to eliminate the moisture as well.
Make sure that you do not have furniture or other items in the crawl space that block airflow to the dehumidifier.
If you have an indoor grow room and want to use a dehumidifier to keep humidity levels low, place the dehumidifier towards the most moist area of the room. If you have a water mister or other moisture-creating devices, keep the dehumidifier on that side of the room to help counteract humidity levels as you add water to your plants.
If you have a small dehumidifier for the bathroom, place it in a spot where it will not be near any electrical devices. This is important because many people use electrical devices in the bathroom, such as a curling iron, blow dryer, or electric shaver. These items need to be far away from the dehumidifier with its full tank of water. Place it on the opposite side of the room.
The dehumidifier should be placed in the bedroom as close to the middle of the room as possible and ideally away from the bed. The dehumidifier can create a strong fan that may be irritating if it blows across your face while you are sleeping. Try to keep it away from curtains and away from the wall.
In a Whole Apartment
For a whole apartment situation, we recommend placing the dehumidifier in the central room, and toward the middle of the room. In this situation, it is best if the dehumidifier can draw in the greatest amount of air to help lower humidity levels throughout the entire apartment.
You may need multiple dehumidifiers to cover the apartment, depending on the square footage of your place.
Where Should You NOT Place Your Dehumidifier?
- Near Dust, Lint, and Air Particles Sources
If you have an area of your home that experiences a lot of dust, lint, or other air particles, then you should keep your dehumidifier away from that area. The dehumidifier is not designed to deal with airborne particles (keep it away from air vents).
- Near Electric Source
Your dehumidifier holds water in its tank. This water should not be near an electric source because if you accidentally spill water on the electric source, you can damage both appliances and hurt yourself. Keep the dehumidifier at least six feet away from any electronic sources.
- Near A Water Heater Or Furnace
A water heater or furnace will have a lot of hot air coming out of it, and this can be problematic for your dehumidifier. Try to keep the dehumidifier in a different space if possible.
- In A Damp Floor Or Moist Carpet
Do not place your dehumidifier on a damp floor or wet carpet because it will not be able to help the area if it is on top of it (the dehumidifier will trap moisture in the carpet). If you place the dehumidifier in the room, it can help draw moisture out, so try elevating it and placing it on a small table or placing it in the next room away from the damp floor/carpet.
- Near A Large Piece Of Furniture
Do not place your dehumidifier near a large piece of furniture. This will restrict airflow and lower the effectiveness of your unit.
- Near Boxes And Storage Units
Do not place your dehumidifier near boxes or storage units because the airflow will be restricted. Any object can restrict airflow if it blocks the path of airflow from the surrounding environment to the dehumidifier.
- Near An Open Door Or Window
If you place your dehumidifier too close to an open window or an open door, then you may find that it takes a long time to reach the desired relative humidity level. This is because the dehumidifier is not only pulling air inside your home into its filter/coils, but it is also pulling in outdoor air. Only place the dehumidifier next to a door or window if it is closed.
People Also Ask (FAQ)
Should a dehumidifier be placed high or low?
A dehumidifier can be placed high or low, but should be placed in an area with good airflow. It also should not be placed on a wet surface such as a damp floor or moist carpet. We also recommend keeping the dehumidifier towards the middle of the room if it is a larger room so that air is pulled in from all directions.
Do I need a dehumidifier in every room?
This depends on the size of your home and the size of your dehumidifier. We recommend placing a dehumidifier on each level of your home and making sure that the square footage capacity of the dehumidifier(s) exceeds your home’s square footage.
Will a dehumidifier regulate the whole house?
This depends on the size of the dehumidifier and its capacity level. A whole-house dehumidifier system will regulate the entire home, but most dehumidifiers are capable of working within a specific square footage.
You may need to buy several small dehumidifiers to place in various rooms around the house if you want to lower relative humidity in each room.
Do you leave windows open when using a dehumidifier?
No, you should not leave windows open when using your dehumidifier. If you do, you may want to turn the dehumidifier off or simply know that it will not be working as effectively as it would if the windows were shut.
The placement of your dehumidifier is an important determinant of how well it works at drawing moisture out of your air. Be sure to look around your home and figure out the best placement for your new appliance. In no time at all, you’ll be living in comfortable 30-50% relative humidity instead of 70-90%.
