What Is Positive Pressure Ventilation

Positive pressure ventilation is a home ventilation method designed to improve indoor air quality by supplying filtered fresh air into living spaces. Rather than extracting stale air out, the system gently pushes clean air into the home, creating a slight positive pressure that forces old, damp air out through natural gaps such as vents, window frames and door openings.

Does air con filter air?

Many people assume that every air‑conditioner cleans the air as well as cools it. In reality, the answer is more nuanced. Modern air‑conditioning units include filters, but those filters are primarily designed to protect the equipment and maintain efficiency rather than to act as standalone air purifiers. Here we explain how air‑conditioning systems move air, what their filters do and how you can optimise indoor air quality.
