Ideally, the best place to put dehumidifier in 2 story house is the room that is the most humid in the house. If you have a 2-story house, then you need to place the dehumidifier on the highest floor and close to stairs, which will effectively dehumidify your 2-story house.

Which is the Ideal Room To Place A Dehumidifier?

The ideal room to place a dehumidifier can vary depending on the house type and other factors. However, typically you should place a dehumidifier in your house’s most humid room. 

If you are wondering how to check the humidity of a room. In that case, devices are available in the market, like a hygrometer, that help you check the humidifier of different areas of your house.

You need to check different spots in your house for the ideal dehumidifier placement. Make sure to check the basement, laundry area, and upstairs as these areas are prone to high humidity. 

However, you also need to consider placing the dehumidifier in an area where it is close to your room and where you stay the most. For instance, if you spend most of your time in the bedroom, then keep the dehumidifier near the bedroom. 

Apart from that, also try to find a central spot in your house where the dehumidifier can have adequate ventilation so it doesn’t run into problems. 

Even though the ventilation is important, you also need to ensure to keep the doors and windows closed, as it can impact the dehumidifier and cause excessive humidity. In such cases, you need to invest in a whole-house dehumidifier.

Whole-house dehumidifiers can be installed in the HVAC system of your house and effectively dehumidify the whole house.

Upstairs or Downstairs: Where to Put A Dehumidifier?

If you are confused about whether you should put the dehumidifier downstairs or upstairs, then we would suggest you put it upstairs. This is due to the fact that most of the humid air goes up, most likely upstairs.

In comparison to the first or ground floor, the second floor of your home will be much more humid, so it is ideal for placing a dehumidifier upstairs as it can dehumidify both floors. 

In addition, some houses are built in such a way that a single dehumidifier cannot dehumidify two floors. In this instance, two dehumidifiers will be required to completely dehumidify the house. If you wish to move the dehumidifier frequently, you may consider purchasing a portable dehumidifier.

Should You Put Dehumidifier In An Elevated Place?

Do You Need 2 Dehumidifiers for Your House?

Deciding how many dehumidifiers to install in a 2-story house can be a challenging task. While some homeowners believe that they need two dehumidifiers to cover both floors, this is not always the case. Before making a decision, it is important to take into account three key factors.

The Capacity of the Dehumidifier

If you want to cover more than one or two rooms with a dehumidifier, then you need to consider investing in a dehumidifier that has at least a 30-pint capacity.
A dehumidifier with a 30-pint capacity can cover up to 500 square feet of area.
Moreover, a dehumidifier with a 50-pint capacity can handle a room of up to 700 square feet. Similarly, if you want to cover a large area of about 1000 square feet, consider investing in a 70-pint dehumidifier model.

Humidifier Placement

Humidifier placement is the most important factor if you want to use one single device for your 2 story building. If you want to dehumidify two rooms, each with 250 square feet area, you need to invest in a 500 square feet dehumidifier model.
However, if there are obstructions, you need to invest in a dehumidifier that has a higher capacity.

Energy Efficient

Opting for a single, energy-efficient dehumidifier can be a better choice than purchasing two separate, inefficient units. 

With an energy-efficient dehumidifier, you can benefit from using up to 15% less energy compared to a standard dehumidifier. This not only saves you money on energy bills but also reduces your carbon footprint and helps protect the environment.

What Are the Ideal Dehumidification Settings for a Dehumidifier?

The ideal or recommended settings for a dehumidifier depend on various factors. For instance, you need to check the relative humidity levels of your house, the temperature, and the size of the house or the room you want to dehumidify. 

Additionally, you need to check the capacity and the type of dehumidifier you are going to use. 

Relative Humidity Levels: The ideal relative humidity level of your house ranges between 30% to 50%. You can also use a hygrometer to check the relative humidity levels. If the humidity is higher than 50%, you need to set the dehumidifier to a low humidity level, like 40% or 45%. 

However, if the humidity level of your house is below 30%, you need to set the dehumidifier to a higher humidity level, like 50% or 55%.

Temperature: The temperature of the room of your home can also affect the ideal dehumidification settings. If the room is colder, you need to set the dehumidifier to high humidity levels. 

Conversely, if the room is hot or warm, you need to set the dehumidifier to a low humidity level. 

Room Size: If you have a large room to dehumidify, you will need to set the dehumidifier to a high capacity to remove the moisture from the air.

Dehumidifier Type and Capacity: A large dehumidifier will be more effective in removing moisture than a small dehumidifier. Moreover, you should choose between a refrigerant and a desiccant-based dehumidifier.


In short, you should place the dehumidifier where the most humidity is present. In a 2 story house, the ideal place to put a dehumidifier is upstairs. 

One thing to keep in mind while placing a dehumidifier is that it should have proper ventilation. Moreover, it is ideal to place it in the center location of your house, if not upstairs. Hopefully, you will find out approach in this post helpful.
