Where to Put My Dehumidifier: Upstairs or Downstairs?

The answer to this depends on some of the basic factors that we will discuss in this article. However, it is very important to understand the correct place to put your dehumidifier, as it will affect its performance and efficiency. A slight change in its placement can have a huge impact on the working of a dehumidifier. 

These changes include on which floor you are putting your dehumidifier, whether it is upstairs, downstairs, or in the middle. How much ventilated is the area? Is it damn enough to use a dehumidifier or not?

Let’s talk about every criteria which can affect the performance of a dehumidifier. This can help us to finalize a place where we can get the maximum performance from it. 

Here we are discussing the most common six factors which can affect the placement of the humidifier in a two-floor building.

1. Temperature

Before placing your dehumidifier, first, check the temperature on the floor. Our main goal is to place the dehumidifier in the coolest area possible. This will enhance its performance.

In most of our houses, the coolest floor is the floor of the basement or the ground floor. So it’s best to place your Dehumidifier downstairs. However, if this is not the case and your house is the coolest upstairs, then you can place the dehumidifier there.

You can also use a humidistat to check and regulate the humidity levels of your rooms and floors. 

2. Detecting the highest level humidity area

We need to detect the high moisture air-filled area in our home to better understand the place where we have to put our dehumidifier. A dehumidifier should be placed where there is excess humidity so it absorbs it and regulates the humidity levels. 

These places can be the basement, kitchen, laundry room, or any room which is filled with moisture most of the time.

It’s best if you place the dehumidifier in the basement area to lock in the extra humidity which is present at the moist walls and floors. 

3. Area having the best possible airflow

It is necessary for a dehumidifier to be placed in an area that has the best possible airflow so air can circulate in that area properly. 

The work of a dehumidifier is to dry out the air, and if you place it in a closed room or in an area that has poor air circulation, then it will take a longer time to complete its work. This will deteriorate the efficiency of your dehumidifier.

You can place your dehumidifier upstairs or in an open place where the air can easily circulate in that area.

4. Finding a good location

It is also important for us to find a perfect spot to put our dehumidifier so it can easily get the required power source to work.

It is necessary to place our dehumidifier where it can easily get the required electricity source to get charged. Otherwise, you will have to move it all the time from here and there to improvise its location. 

It is also necessary to keep in mind that we have to put dehumidifiers in a quiet and dawdle place to keep it safe. This factor promotes putting the dehumidifier upstairs as there will be no rush there. 

5. Which area has more requirements for a Dehumidifier? 

Figure out which area in your house has the most requirement for a dehumidifier, and then pick a place to put it. 

If you think that it is necessary to place it in the kitchen because of the moist surfaces and walls, then you can shift your dehumidifier there. 

Most people find it comfortable to place the dehumidifier near their sleeping spot to have a good night’s sleep. You can also place it somewhere near your room.

Make sure that wherever you place your dehumidifier, there should be less dust and lint in that area. This can damage your humidifier by decreasing its life expectancy.

6. Your personal choice

This is the most important factor of all, what is your personal preference for placing your dehumidifier. 

Analyze your house to pick the places which are very moist and seriously need a dehumidifier to dry out the air in that corner. 

You can also change and improvise the placement of your dehumidifier according to the needs of your house. 

Always choose a dehumidifier that has an in-built humidistat in it so you can also detect the moisture level of the placed area. 

You can also switch in a whole-house dehumidifier; it will evenly dehumidify the whole house, including all the floors.
