Sometimes it’s the simple things that can be done to make your home a healthier and safer one. Bath fans help move a great deal of moisture out of the room and are a really good idea. But where the moisture goes next is just as important.
A ten minute shower can use 16 gallons of water or more, and generate a great deal of steam. It’s not good to leave all that moisture to accumulate on the walls and ceiling in a small room since it can lead to odors as well as mold growth.
So we fire up the fan and it hums away pulling moisture out of the room to…..the attic? It seems pretty simple, but it needs to go to the outside. Often vents end up in the attic or even worse, buried in insulation or a wall and stop there. Every exhaust fan in a home needs to vent to the outside.
Maybe your mirror won’t fog up if it vents to the attic, but moisture will build up elsewhere. Rotting out the roof or growing mold in the attic isn’t any better! Ice dams and roof damage should not be part of your ventilation strategy!
Bath fans can help the whole house too, and I’ve written about it in the past in taking control of the airways. Ventilation is important in our homes, make sure excess moisture gets outside!
