External and internal pollutants can have a significant impact on the quality of air in every home and consequently on occupants’ health.

Poor ventilation is a wide-scale problem. It is estimated that one in five UK households are poorly ventilated, leading to problems with streaming windows, mould growth and poor indoor air quality.
Condensation dampness is the major indoor air pollutant caused by modern living. Energy-efficiency measures such as cavity wall insulation and double-glazing make homes warmer by sealing in the heat. But as a result, the humid, stale air becomes trapped inside the home leading to condensation and the appearance of black mould.
Through everyday life (cooking, cleaning, breathing) the average family produces over 17 pints of moisture a day. Condensation forms when this moisture comes into contact with cold surfaces within the home. This condensation will lead to mould growth, which is not only unpleasant but is damaging to the fabric of the building and creates unnecessary costs for the registered landlord in decoration and maintenance.

Effects on health

Poor indoor air quality has significant impact on the health and wellbeing of occupants. Studies have firmly linked poor indoor air quality with a range of undesirable illnesses, such as allergic and asthma symptoms, airborne respiratory infections, and even lung cancer and stroke.

The importance of good ventilation

Ventilation is critical to home comfort and improved health.
Adequate ventilation improves air quality and rids the home of air pollutants. It controls the moisture levels in the home, preventing condensation dampness and black mould from forming.
These factors combine to enhance the comfort and indoor air quality of the home and ensure a healthy environment. Effective ventilation also contributes to preserving the structural integrity of the home, reducing maintenance costs and adding to the home’s value.
On average, occupants spend over 80% of their time indoors so indoor air quality matters
