Just as a charcoal water filter in a closed air system will take out water, you can use charcoal to reduce dampness in a room. However, it may not work as much as an ideal dehumidifier unit. So how does charcoal dehumidifiers work?

Charcoal contains very little moisture when it comes out from the kiln ( about less than 1%). It quickly absorbs moisture from your humid rooms. This occurs due to its tiny spaces which trap moisture, thus for it to draw enough moisture it should have a large number of pores.

Large pores come with larger surfaces. These surfaces hold odors and moisture with a chemical attraction known as the Van Der Waals forces. Here’s how you use this natural way of handling moisture content in the air.

You can start by getting a big container with a lid. Coffee cans, painter buckets, and plastic containers will do just fine. Add some holes to the side with either an ice pick or a small screwdriver. Throw in the charcoal into the can and return the lid.

You can then place the can in the areas in your that have much humidity. Such places include attics, basements, closets, and even bathrooms. However, you need to change the charcoal every few weeks to make your device work well. You should also know that although charcoal dehumidifiers cannot prevent the growth of mold, they can slow its growth around your home.




Humidity can make your home a mess with mold and stale odor all over the place. You can stop this problem in its tracks using charcoal dehumidifiers as a way to draw the moisture away. Charcoal has pores which help it perform this task. Charcoal Dehumidifiers consist of only charcoal and a container which need replacing once in a while.
