What’s the source for the moisture that’s permeating your home? The shower, wash basins, kitchen sink, and stove are only a few sources. Even breathing puts moisture in your home.
This moisture is more than an annoyance, because it can do real damage to the materials your home is made from, and it can generate the growth of unhealthy mold. Ventilation is the key to solving this problem because it exhausts stale, moist air so it can be replaced with dry, fresh air.
In the kitchen a good range hood will do the trick, but only if you use it every time you cook. Equally important is the bathroom fan. Make sure its CFM rating is the right size for your room, and turn it on every time you take a shower or bath. And for maximum effect, keep it running a minimum of 10 to 15 minutes after you finish bathing.
