During winter the outdoor air spora is usually below the detection limit (if not zero) of the current test methods. Unfortunately, it is during the winter when we spend most of our time indoors. Depending on how well the building is insulated condensation tends to occur indoors during winter resulting in mould growth. Therefore, concentrations of airborne mould spores in indoor environment during winter can be very high.

The following strategies can help reduce indoor mould growth during winter:

• Use exhaust fans whenever cooking, dishwashing, and cleaning to reduce condensation.
• Add more insulation to reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof, or floors).
• Provide adequate ventilation and maintain indoor humidity levels between 30-60%.
