You may have seen the early signs of mold appearing as black spots or green fuzz on your window sills, inner cupboards or inside closets. These are symptoms of poor ventilation, something you need to take seriously, particularly if you suffer from allergies or other respiratory ailments. For a healthy, safe and mold-free home, air needs to circulate and be continually exchanged with fresh outside air.
Proper ventilation is critical in reducing these risks. A simple bathroom fan with a timer or dehumidistat can go a long way to relieving moisture issues in your home by automatically turning on when moisture levels are too high.
This takes care of getting stale, moisture-laden air out of your home, but one of the drawbacks is that it creates a vacuum that pulls air through your home walls, bringing in dust, odors and other contaminants from building materials.
