Optimum Relative Humidity is between 40% and 60% Relative Humidity below 40% causes the
spread of bacteria, and viruses, which attack the respiratory system. Relative Humidity
above 60% not only promotes bacteria, and viruses but also encourages mould growth and
increased activity by house dust mites, which can trigger allergies.
Excess humidity in dwellings causes condensation and mould growth
problems to develop and presents a real threat to the health and safety
of the occupants which can render a property unfit for habitation. |
