Will A Dehumidifier In The Basement Help The Whole House?


Basements are usually the dampest and coldest area of any home.

This humidity can often spread to other parts of the home, especially if a timber floor is the only barrier between basement and upper levels.

We’re often asked whether buying a powerful basement dehumidifier will also provide benefits to the rest of the home. In this guide, we’re going to answer that question.

The Short Answer

Yes, the right dehumidifier in your basement can help reduce humidity levels throughout your entire house. The right dehumidifier is one that is powerful enough.

This could be a whole house dehumidifier or a commercial dehumidifier. The type doesn’t matter. What matters is that it is powerful enough to keep your basement dry.

Once humidity levels start to fall, the masonry is your basement will hold less water, preventing it from being transferred upstairs.

Why Use a Basement Dehumidifier

A basement dehumidifier is ideal because they are designed to be run continuously. Its also the perfect location to install one as you won’t be able to hear it upstairs.

You can check the humidity level of your basement with a hygrometer. The following symptoms are also signs of a damp basement:

  • Damp walls
  • Visible mold on surfaces
  • Condensation on surfaces
  • Stale, musty, or moldy odor
  • Stuffy air
  • Peeling paint or wallpaper
  • Watermarks on surfaces

Dehumidification is the key to a dry and healthy home. Dehumidifiers reduce excess moisture in your house's atmosphere, which has multiple benefits.

You won't have to worry about mildew or mold growth; dust mite allergens are less likely; insects cannot thrive with low humidity levels. Additionally, dehumidified air protects your furniture (particularly wood) as well as drywall and paint from damage due to dampness.

A dehumidifier provides you with a better air quality, but it can also save money in the long run. This is because your AC won’t have to work as hard if you use a dehumidifier to reduce humidity.

A basement is the best place to install a dehumidifier because it has an increased moisture level. Basements are especially prone to humidity problems, so installing a system in this location will help reduce levels of humidity all over your house.

Whole-House vs. Portable Dehumidifiers

A basement or whole whole dehumidifier is better than a portable dehumidifier for several reasons.

A whole-house dehumidifier removes excess moisture from the entire living space. This is due to using powerful fans and ducting. These components work together to move dry air around the home.  

Basement dehumidifiers don’t usually utilize ducting and instead dehumidify the surrounding air. They still make a difference as this dry air will naturally find its way through your home.

Portable dehumidifiers aren’t powerful enough to do this. They might be able to reduce humidity in your basement, but they won’t be able to get the air as dry, as quickly.

Basement and whole-house dehumidifiers are bigger and more durable. They are designed to run continuously for years with minimal maintenance.

FAQs: Basement Dehumidifiers

Should You Run a Dehumidifier in the Basement All the Time?

It depends on how damp your basement is. We recommend using the dehumidifier all the time if the humidity level is above 60%

Where in the Basement Should I Place the Dehumidifier?

As centrally as possible, with maximum airflow around it.

Try and avoid walls and other obstacles. Don’t place it near water.

Are Whole-House Dehumidifiers Worth It?

Whole-house dehumidifiers are worth the money because they can improve the air quality throughout your home. This provide a more comfortable home and will eliminate moisture related problems.

How Often Should You Dehumidify a Room?

Whenever humidity starts to rise. Always try and keep the level of relative humidity below 50%.

Do I Need a Dehumidifier in Every Room?

A portable dehumidifier is most effective in the room it’s placed in. They can operate in multiple rooms if you leave the doors open, but effectiveness is reduced.  

A whole-house dehumidifier requires only one unit for the entire household.

Final Verdict

Dehumidifiers can dehumidify your entire house if they’re powerful enough.

A whole-house dehumidifier can reduce the humidity level to 50% or below across the home, protecting your interior, structure, paint, wood, wallpaper and even your family’s health.
