Combat Damp, Condensation, and Mould While Improving Indoor Air Quality
Air Quality Improvement with Positive Input Ventilation in Dorset & Hampshire
Maintaining good indoor air quality is crucial for a healthy, comfortable home. Poor ventilation can lead to damp problems, condensation, and mould growth, causing structural damage and health issues.
At Proofterior, we provide expert Positive Input Ventilation installation in Dorset, Hampshire, and surrounding areas, helping homeowners eliminate excess moisture and enjoy a fresh, clean, and healthier living environment.

What is Positive Input Ventilation (PIV)?
Positive Input Ventilation systems work by introducing filtered, fresh air from outside into your home, gently pushing out stale, moisture-rich air that can lead to mould and condensation.
Unlike extractor fans that remove air without replacing it, PIV systems ensure continuous airflow and balanced humidity, reducing the risk of damp, musty odours, and condensation damage.

Benefits of Installing a PIV Unit
Mould and condensation prevention – Keeps humidity under control, eliminating conditions for black mould and damp patches.
Improved indoor air quality – Filters out allergens, dust, and pollutants for cleaner air.
