Moulds are fungi that grow in damp environments, and allergic people who come into contact with them can experience reactions and respiratory problems.

 Since moisture promotes mould growth, dampness is one of the most common causes of poor indoor air in homes, classrooms and public spaces. Controlling the level of moisture is one of the best and easiest ways to improve indoor air and protect your health.

• Biological pollutants are living organisms like mould, bacteria and dust mites.

• Chemical pollutants are gases and particles that come from combustion appliances, tobacco smoke, household and personal care products, various building materials and outdoor air.

A lack of ventilation, especially in air-tight buildings, is a key factor that impacts the quality of indoor air.
