Exhaust fan essentials
- The standard bearer: Ceiling-mounted exhaust fans are the workhorses of bathroom ventilation. Choose a model with a capacity appropriate for your bathroom size with features like timers.
- Space-saving solutions: Wall-mounted exhaust fans are perfect for smaller bathrooms. They offer similar functionality to ceiling fans and often come with integrated light fixtures for added convenience.
- Hidden helpers: In-line fans are installed within the ductwork and work seamlessly with a remote ceiling or wall vent. This option is ideal for spaces where access to the fan itself might be limited.

Natural ventilation ideas
- Harness the breeze: Open windows whenever possible, especially during and after showers. Natural ventilation provides an eco-friendly way to remove moisture and odours.
- Light up the space: Consider installing skylights or light tubes for additional natural light and passive ventilation.

Modern ventilation advancementÂ
- Humidity sensors: Upgrade your exhaust fan to a model with a built-in humidity sensor. These fans automatically turn on when moisture levels rise and switch off once the air is clear and ensure optimal ventilation.
- Heat recovery ventilation (HRV): This innovative system captures heat from outgoing moist air and transfers it to incoming fresh air. HRVs provide superior ventilation while minimising heat loss, making them ideal for colder climates.

FAQs
Do I need a window and a fan?
Building regulations typically require either a window or an exhaust fan for ventilation. If your bathroom only has a toilet, a window might suffice.
What size fan do I need?
Fan size is measured in CFM (cubic feet per minute). The CFM rating should match your bathroom's size. A good rule of thumb is 1 CFM per square foot of bathroom area.
How long should I run the fan?
Run the fan for at least 15-20 minutes after showering to remove all moisture. Timer switches on fans ensure this. Humidity sensor fans automatically turn on when needed.
Are there quiet ventilation options?
Look for fans with noise ratings below 3 sones for quieter operation. Some fans offer multiple speed settings for balancing noise and airflow.
How can I improve natural ventilation?
Open windows during and after showering. Consider skylights or light tubes in windowless bathrooms to promote natural airflow and light.
How do I clean my exhaust fan?
Disconnect power and remove the fan cover. Clean the grille and blades with warm, soapy water. Wipe down the fan housing with a damp cloth.
What are the signs of poor ventilation?
Musty odours, peeling paint, condensation on walls, and visible mould growth are all signs of inadequate ventilation. Address these issues promptly.
