Positive Input Ventilation – How Does It Work?

Positive Input Ventilation (PIV) is a wonderful way to regulate the quality of indoor air. This kind of system lets in a stream of pure air into a home, thereby getting rid of humid, stale air which leads to dampness problems- such as condensation. Generally, PIV systems are small. They are attached to the duct of landings, hallways, and other common spaces, on flat walls and in-home lofts.
