Preventing Moulds

A crucial factor in avoiding a mould infestation is reducing the indoor humidity to prevent moulds from growing. Most species require a relative surface humidity of at least 75%.

Humidity can be introduced from outside the home in connection with water damage and leaks, which is why regular building maintenance is important. The main sources of humidity are daily activities such as cooking, bathing and drying clothes. These daily activities emit considerable moisture, which condensates on material surfaces, increasing the relative humidity.

Air your home frequently (especially in connection with cooking and bathing) to avoid increased indoor humidity. Airing the bedroom is another key factor in limiting indoor humidity, as people produce considerable quantities of humidity during sleep. Furthermore, many people prefer to sleep in cold bedroom, which increases the risk of condensation.
