Why Condensation and Mould Occur
The Science Behind Condensation
Condensation occurs when warm, moist air meets a cold surface. Everyday activities like cooking, showering, or drying clothes indoors release moisture into the air. In a poorly ventilated space, this moisture settles on cold surfaces, such as windows, walls, and ceilings, causing dampness. This dampness fosters mould growth.
How Mould Thrives
Mould thrives in warm, moist conditions and can lead to respiratory problems, allergies, and asthma. Controlling excess moisture is essential to prevent the harmful effects of condensation and mould. That’s where our condensation ventilation system steps in to help.
The approach to solving the problem of both condensation and mould is, therefore, controlling the source-the excess moisture within the air. If not eradicated, they can continue spreading.

How Positive Input Ventilation Works
The Core Mechanism
A PIV unit for condensation brings fresh, filtered air into your home, creating positive pressure that pushes out stale, damp air. This continuous airflow prevents moisture buildup and ensures your home stays dry.
Our Vent Axia PoziDry Pro is a high-performance Anti Condensation Unit, equipped with advanced filters and designed for energy efficiency. It not only eliminates excess moisture but also enhances indoor air quality, keeping your home healthy and comfortable.
Health and Energy Benefits
Health and Energy Benefits By maintaining optimal humidity levels, our PIV units for mould and condensation improve air quality and eliminate musty odors. Plus, controlling humidity reduces heating costs, as damp air makes your home feel colder and forces your heating system to work harder. With a PIV for condensation, you can enjoy a fresher, more energy-efficient home.
Our solutions also include a Positive Input Ventilation system for mould, designed to prevent dampness and create a healthier environment for your family.
