You’ve bought a dehumidifier to help remove the moisture in your humid home, but where is the best place to put dehumidifier in 2 story house? Should you put it upstairs, downstairs, in the basement, near the stairs or some other place? In this blog, find out how to decide on the best place for your dehumidifier so that it works efficiently.

Best place to put dehumidifier in 2 story house
There are factors to consider when thinking about the placement of your dehumidifier in your 2 story house.
Let’s take a closer look at each of these factors!
Temperature of your home
You know by living in a 2 story house that the top floor is always hotter because hot air rises to the top. An upstairs bathroom is not only warmer than a room downstairs but is more humid due to the nature of bathrooms.
The downstairs part of your home tends to be cooler.
The warmer the room temperature, the more moisture there is in the air, unless the air is very dry which can often happen in winter due to heating.
If we assume that the top floor of your 2 story home is hotter than the bottom floor or the basement, the ideal placement of a dehumidifier is on the top floor. This way, the dehumidifier can focus on removing the moisture from the air upstairs.
If you need to use a dehumidifier during winter, be careful if you’re using it downstairs because the temperature is cooler and if it is below 65 degrees Fahrenheit, this can cause ice to form on the dehumidifier’s coils.
The humidity level in your home is the measure of how much moisture there is in the air and is expressed as a percentage. A normal humidity level is anywhere between 30% and 60% but this can fluctuate.
Using a digital hygrometer, you can determine the humidity level of different rooms in your home.
Again, we can assume that as your upstairs area is warmer than downstairs, the humidity level upstairs would be higher than it is downstairs. So again, the best option is to place the dehumidifier upstairs where the humidity level is higher.
If you want the dehumidifier to cover the entire upstairs area, you would need to leave all the doors upstairs open so that the humid air can be reached by the dehumidifier.
If you have a bathroom upstairs, this would be the most humid room in the house, so an additional dehumidifier in the bathroom would be ideal. You can use a smaller dehumidifier in the bathroom, and another dehumidifier for the rest of the upstairs floor.
Air flow and obstructions
To prevent problems such as the dehumidifier not working properly or ice forming on the coils, find a place that has good air flow and doesn’t have anything that could obstruct the air flow from the dehumidifier.
If you’re placing your dehumidifier upstairs where it’s more hot and humid, find a space that is fairly open and not near furniture. Do not place the dehumidifier right against a wall as this will obstruct air flow.
If your upstairs area only has a long narrow hallway, then this may not be a good option for using the dehumidifier upstairs. You might need to consider whether you need a dehumidifier for individual rooms.
Otherwise, try placing it close to your stairs (without obstructing the walk way!) where there is more airflow.
Find a clean area
Dust, dirt and other particles can damage a dehumidifier, so it’s a good idea to find a space that is usually fairly clean and dust-free.
Be careful of placing the dehumidifier near a door or window as these areas attract dust and dirt especially when they are open.
As you need power to operate a dehumidifier, you will need to find a place that is close to a power outlet or you can use an extension cord to help you access the power outlet.
Should you use more than one dehumidifier in a 2 story house?
One dehumidifier is not enough to dehumidify an entire home, especially a 2 story home. This is when it is best to use a whole house dehumidifier that is placed near your furnace and can dehumidify your whole home. It’s a more effective and economical option!
You’ve chosen where to put your dehumidifier- now what?
Once you start using the dehumidifier upstairs in your desired spot, take a humidity reading using a digital hygrometer. This can help you check whether the humidity level is decreasing after using the dehumidifier. Make sure you take a reading before using the dehumidifier as well as while using it, so you can compare.
If the humidity level isn’t decreasing, then look at different options such as a more powerful dehumidifier or a whole house dehumidifier.
One Final Word
The best place to put dehumidifier in 2 story house is somewhere that is close to a power outlet, free of obstructions and in an area with good air flow.
If this is not possible, then consider investing in a whole house humidifier.
Choosing between upstairs or downstairs, upstairs is where the air would be more humid as it is hotter than downstairs. The upstairs bathroom would be the most humid room in the home. If you have a laundry upstairs, this would be hot and humid too.
Consider the different aspects we’ve covered in this article before you decide where to place your dehumidifier. If the chosen spot isn’t as good as you first thought, try a different spot upstairs.
