How a Positive Input Ventilation System Works

The PIV unit draws fresh filtered air into the home and gently ventilates from a central position on the landing or central hallway. Stale, moisture-laden air is diluted, displaced and replaced with subtle fresh filtered air forcing contaminants out of the property through leakages or extract points in wet rooms (if applicable)
