- It's estimated that 70 per cent of the health problems people experience in the indoor environment are due to poor air quality or poorly cleaned ventilation.
- Such problems can often be prevented by checking that the ventilation systems are working properly.
- Ensuring that a sufficient amount of air is exchanged also has a major impact on air quality. The ducts need to be cleaned and it is also important to change filters regularly, preferably every spring after the pollen season and every late autumn after a damp and potentially mouldy autumn.
- If moisture enters the ventilation system, it can contribute to the formation of irritants and lead to the growth of microorganisms
- Many buildings struggle with moisture damage and subsequent mould growth. However, the recommended norm is clear:
- Moisture and rot damage, as well as visible mould and mould odour, must not occur.
