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. This kind of system works slowly and draws pre-heated air constantly into the property. In just a 24-hour period, this air is fully replaced several times. Positive Input Ventilation system if you are facing respiratory problems due to allergies, black mould issues, or condensation problems, you would benefit from installing this kind of system in your home.
