Bathroom Extraction Fan
Bathroom extraction fans are required for better ventilation. Condensation in a bathroom is very common, it is easy for mould to grow in the bathroom. A bathroom extraction fan will help in reducing the moisture in the air and increase the clean air levels. It also helps in eliminating odour as well as fumes.

The fan must vent extracted air to outdoors. Continuously operating extractor fans that operate at a level of extraction below 25 litres per second, or do not have a fan and ducting diameter of at least 120mm, are not capable of providing the necessary level of moisture extraction during
Installed BEFORE 1 July 2019: No minimum size or performance requirements but fans must be in a good working order and ventilate to outdoors.
