Using a dehumidifier can help bring the humidity down in an overly humid home. They can also reduce the buildup of mold and dust mites. If you already have mold in your home, a dehumidifier won't remove it. It can, however, reduce or eliminate additional mold growth.
What are the disadvantages of a dehumidifier?
Con: Noise and Heat
Dehumidifiers also tend to blow warm air out of the back of the unit. In the winter, this can be an advantage -- but not so much in the summer. Position the back of your dehumidifier in a doorway so that it doesn't heat up the room from which you are removing excess moisture.
When should you use a dehumidifier?
Use a dehumidifier:
- When days feel warm and humid.
- When allergies due to dust mites, mildew/mold, or pollen are suspected.
- Anywhere/anytime you see mildew, mold, or condensation developing.
- When the humidity level in your indoor air exceeds 50 percent.
