Positive Input Ventilation (PIV)

Fresh, Clean Air That Fights Damp

Condensation damp, mould growth and stale air are often caused by poor ventilation. Homes trap moisture from cooking, bathing and everyday living, especially during colder months. This creates the perfect environment for mould spores and allergens to spread.

Healthier Airflow for Your Whole Home

A PIV unit gently introduces filtered, fresh air into your property, pushing out damp, stale air and balancing humidity levels. This continuous airflow reduces condensation, prevents mould from returning, and improves indoor air quality year-round.
Low-energy, quiet and highly effective, PIV is one of the best long-term solutions for keeping your home dry, healthy and comfortable.
