A BA fan (often written as Bathroom Exhaust Fan or simply BA exhaust fan) is a ventilation device installed in bathrooms to remove excess moisture, steam, and odours from the air. In simple terms, a BA fan is a mechanical air extractor that helps keep bathrooms dry, fresh, and free from mould-causing humidity.
Here’s why it matters: bathrooms are naturally high-moisture environments due to showers, baths, and hot water use. Without proper ventilation, this moisture lingers in the air and settles on walls, ceilings, mirrors, and fittings—leading to mould growth, peeling paint, and unpleasant smells. A BA fan solves this by drawing humid air out of the room and replacing it with fresher air from outside or adjacent spaces.
The main reason homeowners install a BA fan is to protect bathroom surfaces and improve indoor air quality while maintaining a cleaner, healthier environment.
