It’s Dehumidifier Season, But Do It Right

A lot of people have dehumidifiers, and a lot of them are making serious mistakes in their use. Of course, a lot of people don’t have dehumidifiers who should, and that’s perhaps an even bigger mistake.

Moisture is the key ingredient in indoor mold problems. If you can control moisture, you won’t have a mold problem. So if your roofing, siding, windows, plumbing and ventilation systems are all without issues, what you have left is relative humidity, a term that describes the amount of water in the air relative to the amount of water the air could hold at its current temperature.

We published a detailed article on dehumidifiers in the summer issue of our seasonal magazine, Habitat Quarterly. We also reposted it here on 1800gotmold.com, so you can read it in either place.

Here’s a snippet:

Although your air conditioner does behave like a large dehumidifier, often it can’t keep up with the infiltration of humid air from outside, especially in very humid climates. In other cases, dehumidifiers are needed in spaces which aren’t affected by your heating or cooling systems, such as crawlspaces. Plus, you still need to control humidity during the nine months when your AC is not running, especially in basements and other scenarios prone to dampness, such as houses built on wooded lots.

So, if you have a dehumidifier, are you using it correctly? And if you don’t have one, should you? Read on and find out.
