Positive Input Ventilation, or PIV, also known as positive pressure ventilation, works as a ventilation system for the whole house. The loft mounted Brookvent airplus PIV is an ultra-quiet, low-energy, and low-maintenance way to create a fresher, healthier living environment by continuously supplying fresh, filtered air. Using the PIV principle, these units prevent and cure condensation and damp problems, and are also efficient at combatting other air pollutants – and even in reducing Radon gas levels.
