Dehumidifier Placement In A Two-Story Building Factors To Consider

The factors that affect the placement of a dehumidifier in a two-story building are:

Ease Of Access

You might want to keep the dehumidifier close to an electrical outlet, so it's easy to plug it into power when needed. However, if this isn't an option, consider getting an extension cord so that you don't have to move the unit around too much.

Consider The Noise

Dehumidifier creates noise pollution. Therefore the second most important factor is how much noise you want to hear from the dehumidifier. If you want minimal noise, place it in a room where you spend most of your time. If you want maximum noise reduction, place it somewhere, not directly next to any rooms where people sleep or watch television.

Area Of Ventilation

Make sure that any area where you plan to place the dehumidifier has plenty of ventilation so that air can circulate freely around it at all times. This ensures that moisture does not build up inside the machine and causes damage over time.

Size of the Building

The size of your house or office will determine how many dehumidifiers you need to install. For example, if you have large offices with many employees, you may need more than one unit for each floor.

How Should A Dehumidifier Be Placed? Upstairs Or Downstairs?

The question of whether or not you should place the dehumidifier upstairs or downstairs is one that many homeowners face.

Some people place their dehumidifiers on an upper floor because they want them to be out of sight. Others prefer to put their dehumidifiers in basements because they want them close to where they live and sleep.
