Hi frodo33a, and thanks for your post. Are you experiencing a mold issue? In the most general of terms, a mold issue (in the home) is usually the result of excess moisture/water/humidity of some kind. If this is the case, one would want to make certain the mold condition(s) are cleaned up properly. At that point, if it was warranted, one might want to look into the use of a dehumidifier.
What do you think?
