Best Dehumidifier For Basement Use

best dehumidifiers for basement use
With health and damage issues resulting from a damp basement or crawlspace, choosing the best basement dehumidifier is important.

Basements are underground and as a result, are typically cool and damp. These are the perfect conditions to promote the growth and spread of mold and mildew. Not only does this have an effect on the health of those living in the home, but it can also cause other problems.

A cool and damp basement presents the right environment for rot, the infestation of insects, and other pests and can result in structural damage to the home. To reduce the risk of these potential problems, a dehumidifier can work to remove the dampness in your basement.

Why Do I Need A Dehumidifier In My Basement?

A whole basement dehumidifier will work to regulate the humidity in the low-temperature damp environment, but it will do much more. With a built-in air purifier using a HEPA filter, it will trap airborne mold spores stopping them from spreading throughout the damp space.

A carbon filter will also absorb odors leaving a clean scent. This is especially important if your basement is an extension of living space or if the crawlspace is used for storage.

How Do You Know If You Need A Dehumidifier In Your Basement?

There are several signs to watch for that will tell you that a dehumidifier is needed in your basement. These include:

  • mold growth on walls
  • clammy air
  • the smell of mold or mildew
  • walls that feel damp
  • Rust and corrosion appearing on metal objects
  • moisture rising from the floor, and
  • items stored there that smell moldy or bad.

A basement dehumidifier is designed to tackle all of these conditions and restore the area to a safe, dry, and healthy living or storage area. Since the air circulates around your whole home, reducing the dampness in your basement removes mold and mildew which can have an effect on the air you breathe elsewhere in your home.

What Is The Ideal Setting For A Dehumidifier In A Basement?

High humidity levels in a basement can lead to several problems related to damp conditions. However, keeping the moisture level too low can also be an issue. We have already discussed what can happen if the conditions are too damp, however, if you use your basement as a living space, with dry conditions other problems develop including dry, itchy, and cracking skin on the lips and hands.

The solution is to keep basement humidity levels “somewhere in the middle”, although the rest of your home will likely have a different humidity level than in your basement or crawlspace. Generally speaking, the house humidity would be slightly lower than that of the basement of the same home.

What Is The Ideal Humidity Level For A Basement?

As for actual Relative Humidity levels, a basement can tend to already be very damp. This means that it is often advisable for the moisture content to be somewhat controlled. As a general guide, the basement should not exceed 65 percent humidity.

Compared to the rest of your home, the average room humidity should be between 30 and 50 percent. You will be removing water – possibly up to 100 pints daily – with the majority of that coming from basement air.

If you are unsure of the humidity levels within your home and basement, you can always monitor it. To make accurate humidity readings you should use a hygrometer.

How Do I Prevent Mold In My Basement?

Water is the cause of mold in your basement so in order to prevent further spread you must locate the source of the moisture. If there is a plumbing leak or water coming through a crack in the foundation, you will need to have these problems professionally repaired.

For more information on why you might need a basement dehumidifier, make sure to check out the short video below. In the video, Tom talks about the Sante-Fe compact dehumidifier. While we have not reviewed this specific dehumidifier model, the video still provides some useful information. As well as this, the AlorAir 90-pint dehumidifier below does a similar job to the one mentioned in the video.

If the mold is created by high moisture content in the air in the basement or crawlspace, your best remedy is to install a dehumidifier. There are several types and styles to choose from.
