Removal Of Moisture

Moisture is the main pollutant in the home. It is generated by everyday activities like washing, cooking and bathing.

If it is not removed, it can lead to condensation, damp and mould growth - resulting in poor health and damage to the home.

A ventilation strategy that controls moisture will control other pollutants too (such as VOCs, CO2 and odours). Maintaining relative humidity at a level below 70% will prevent excess moisture building up, and prevent problems such as damp and condensation.

It is better to use a ventilation system to remove moisture rather than rely on natural leakage or open windows, as:
  1. you can control the level of ventilation so you don't under- or over-ventilate. Plus buildings are built to high levels of airtightness nowadays - with hardly any gaps for cracks for moisture to escape.
  2. open windows might be a security risk or simply not convenient. Again, you don't know how much you are ventilating the property and you might just be letting all your (expensive) heated air out.

Ventilation systems are carefully designed to operate at the right level and minimise the loss of warm air. Damp, stale air is extracted through extracts and expelled through the roof.
