Best Place To Put A Dehumidifier

Dehumidifiers are appliances that will reduce the amount of humidity in the air, mostly for an enclosed structure or room. The device does so by extracting moisture from the air in a high humid place in a house. To achieve the objective of investing in this appliance, you need to know the best place to put a dehumidifier.

The best position for your humidifier is the place that you need it most. These are areas where humidity levels are higher than expected. Some of the rooms with excess humidity levels include; bathrooms, basements, crawl spaces, bedrooms, and workshops.

Placing it in the right position will improve the quality of breathable air and prevent mold damages on your surfaces.

Dehumidifiers are mostly used in residential houses. However, different industries are also embracing the use of these devices.

Factors To Consider When Figuring Out The Right Placement For Your Dehumidifier

It is not every high humidity place in your house or office that is ideal for placing a dehumidifier. Three key factors will guide you where to put it.

The source of humidity

Humidity can come from different sources, either from inside your house or from outside.

The internal sources could be from your oven or shower, while the external sources could be through the window or door.

Once you have determined the primary source of the moisture, place the dehumidifier near it, this is to allow the appliance to work efficiently.

It will trap the humidity before it spreads to the other areas of the house.

Look at The size of the room

Are you looking to dehumidify a large room like a sitting room or basement area? Or it’s a small space like a bathroom?

The size of the space will determine the size of a dehumidifier to use and where to place it.

For a big area such as a living room, you should set the dehumidifier in the center of the room to allow maximum coverage.

If you want to dehumidify a small space, the positioning may not matter because there is little range to cover.

Restrictions to airflow

Check out for any airflow obstructions to and from the dehumidifier.

For the best performance of the dehumidifier, it should be placed where there is adequate airflow.

Do not place the dehumidifier should not be placed near physical objects such as furniture and walls.

It requires unrestricted airflow for it to function effectively.

An ideal place to start with is at the center of a room, free from any air obstruction.

Remember, the dehumidifier has a tank that may overflow as it is dehumidifying. Avoid placing this device near electronics or anything that you do not wish it to get wet.

Which Humidity Levels Requires a Dehumidifier?

Generally, the relative humidity level for a home should be in the range of 30% to 50%.

Unless in situations where you are protecting valuables such as guitars and items that require special conditions, humidity levels shouldn’t go beyond 50%.

In normal circumstances, humidity levels beyond 50% can promote the growth of molds, bacteria, and other unwanted pests.

It can also lead to swelling on the wall paint or even rotting of furniture. In comparison, a relative humidity level that is below 30% can increase the chances of contracting flu, experiencing dry skin, cracked ceilings, and other unwanted effects of extremely dry air.

It is, therefore, essential that you get a humidity testing device. This will help you determine when you require to switch on the dehumidifier.

Some dehumidifier models come with comes with a range of humidity settings. You can set your humidity levels where the device can power on or off.

Which Rooms Are Ideal To Place a Dehumidifier?

While a dehumidifier is placed in an area with moisture, particular areas such as bathrooms, kitchens, basements, bedrooms, living rooms, and crawl spaces experience excess moisture.

If you are not sure about the areas with excess humidity levels, a hygrometer will help you.

Isolate the area with high humidity to prevent the spread of moisture to other areas of your house by closing the doors of the specific room(s).

Bring the dehumidifier into the room and shut all the windows to prevent extra humidity from outside coming in.

Placing A Dehumidifier Inside A Bathroom

Humidity levels in the bathroom increase when you are taking a hot shower. The steam that you see in the air as you taking a shower is moist air.

The presence of this vivid steam means that the air can no longer hold the moisture, which can be interpreted to mean that the humidity level is at 100%.

This situation is common in cases where there is no exhaust fan or ventilation to dissipate the moisture.

When this steam condenses, it creates a perfect environment for the growth of molds and mildew.

It may also cause rotting of any wooden item in your bathroom and may even cause your bathroom paints’ fizzing.

The presence of mildew, molds, and fizzing of paint is a sign that you need to place a dehumidifier in your bathroom. So when should you run the dehumidifier and for how long?

Right after taking a shower, you should run the dehumidifier for approximately 20 minutes.

With the small room in the bathroom, you should get a small dehumidifier, one that you can place on a shelf, toilet bowl, or in the middle of the bathroom without any difficulties.

Placing A Dehumidifier In A Kitchen

Kitchens are other sources of high humidity in a house. Dishwashers, refrigerators, kitchen sinks, and cooking can increase the level of moisture in your home.

Getting rid of high humidity levels in the kitchen is easy since you can easily trace the source.

If your kitchen sink or drain is the most significant humidity source, place a small dehumidifier beside the sink, this should be enough to deal with high humidity coming from the sink.

In cases where there is high humidity when you are cooking, placing a dehumidifier near your cooker will maintain dry air in your kitchen.

Regardless of the high humidity source in your kitchen, always ensure that you place the dehumidifier where there is sufficient airflow. Avoid placing it in a tight space or a corner.

Having A Dehumidifier In The Basement

It is a common occurrence to expect high humidity levels in the basement area of your house. Basements are likely to have high humidity levels because of various reasons;

  • Because the walls are underground, they are likely to seep in water.
  • Basements rarely have adequate ventilation.
  • Most homeowners put washers and water heaters in the basement; these are moisture-containing devices.

It is, therefore, common to find mold infestations in the basement. If you don’t take any action, the mold infestations can compromise the structural integrity of your house.

Since most basements are enclosed, it becomes easier to manage high humidity instances.

Placing a dehumidifier in your basement will help you keep away extra humidity from your basement.

It is easier to use a dehumidifier in the basements because of installed drainage systems, which means you can quickly drain the dehumidifier tank into the drainage system.

If you own a big basement area, then you need to have a big dehumidifier. Check on the dehumidifier’s product description to ensure that its ratings can serve the size of your basement.

For maximum performance of the dehumidifier, ensure you place it in a central position.

The number of hours that you will need to run the dehumidifier in your basement will depend on the size of the basement and the capacity of the dehumidifying appliance.

Placing A Dehumidifier In A Living Room

Placing a dehumidifier in a sitting room can be a little bit tricky. It is because sitting rooms are one of the largest rooms in a house.

While you are required to place a dehumidifier in the middle of such a large room, placing a large dehumidifier in the center of the sitting room may consume a lot of space.

Identify the source of humidity and position your dehumidifier close to it.

The chances are high that the front door is the primary source of moisture in your living room; placing the dehumidifier near the entrance is ideal than at the center.

For the best results, ascertain that the dehumidifier is big enough for the sitting room.

Also, ensure that the doors and windows are shut when dehumidifying.

Placing A Dehumidifier In The Crawl Spaces

The crawl space is one area in a house where molds can go unnoticed because they are rarely in use or access.

High humidity can accumulate in this area, leading to mold formation and even weakening the surrounding areas.

During the colder months, humidity increases more in the crawl spaces and ceiling. This is when the inside temperatures are warmer than the outside.

Poor insulation around these areas can also be the reason for the accumulation of high humidity.

The type of dehumidifier that you will place on the crawl space or ceiling is different from the rest.

You will need a dehumidifier that has a more robust fan, which will ensure dry air gets to the furthest corner or joints in the crawl space.

Therefore, you should check the type of dehumidifier you are going to place in the crawl space and ceiling.

While the crawl space may be small, ensure that the dehumidifier is placed away from any obstruction. Put it at the center.

Get the right size dehumidifier for your crawl space, and you will not have to worry about mold infestation on your crawl space and ceilings.

Place A Dehumidifier In The Bedroom?

Yes! Having the right humidity levels in your bedroom will give you a good rest and improve your health. Remember, the bedroom is one place where you don’t need any form of air contamination.

The level of humidity in the bedroom increases with houseplants’ presence in your bedroom and leaky windows.

Because most bedrooms are not relatively large, a small dehumidifier is sufficient to restore the right humidity levels in your bedroom.

If possible, place it at the center of the bedroom to ensure dry air gets to all areas of your bedroom.

A Dehumidifier To cater For The Whole House?

A portable dehumidifier may not be ideal if one is experiencing high humidity conditions in the whole house.

Instead, getting a whole-home dehumidifier is the best solution.

It is a powerful dehumidifier suitable for a house with thousands of square feet.

Because of its immense size, such a dehumidifier can easily incorporate with an HVAC system in one’s home.

How To Tell Whether The Dehumidifier Is Working Or Not?

If you don’t have any electrical knowledge, telling whether your dehumidifier is working may turn out to be tricky. Here are some tips to help you ascertain whether it is running or not.

  • Dehumidifiers have an automatic switch that switches it off when the tank’s water level is at maximum. If the water level is not maximum and the dehumidifier is on but not running, check out whether the tank is in the correct position; the switch may have been activated accidentally. Re-position the tank to switch it on.


  • If the dehumidifier is running but no significant increase in the tank’s water levels after a considerable time, there could be an issue with the refrigeration side that may need a professional to address.


  • A functioning dehumidifier has a fan that sucks air from the atmosphere. If there is no air coming out when the dehumidifier is running, the fan motor may require a replacement.

Final Thought

Knowing where to place your dehumidifier should not be a difficult task for you.

You should put a dehumidifier in any area with high humidity levels than expected, which could be the humidity source.

Check on the size of the room you want to dehumidify against the dehumidifier’s capacity and ensure they match.

Check out to ensure there is no airflow obstruction in the position you are looking to place the appliance; this will guarantee its efficiency.

Close all the doors and windows of the room you are looking to dehumidify.
