 If you're considering remodeling your basement, you need controlled ventilation to exchange the air you breathe. You should do what one of my listeners did and get an EasyBreathe ventilation system. Donald Dimion in Pennsylvania wrote, We were so surprised at how quickly the EasyBreathe improved our air quality. The humidity is under control now and the dampness has left the basement along with the mold and mildew smells. Excellent product and works just as good as Gary Sullivan said it would.
