How to Choose the Right Exhaust Fan for your Bathroom

Exhaust fans help remove bad odors as well as condensation caused due to showers and baths.

Bathrooms that lack any natural ventilation, such as a window, home owners are required by the Australian Building Code to install exhaust fans that serve as a mechanical way of getting rid of moisture and smells.

Recently, one of our electricians visited a residential property in Melbourne, where the owner wanted us to install an exhaust fan but didn’t know which one best fits his needs. So to help our customers make an informed decision, let’s take a look at what features you should be looking for when buying an exhaust fan.

1. Start with the Size

To begin with, your exhaust fan should have the capacity to throw out moisture and bad air from the room it’s being installed in. If it’s too small compared to the room size, it will not serve its purpose. If it’s too large, you might end up wasting energy.

Exhaust fans have an extraction rate which is measured in terms of number of times it changes the air per hour. So if you want to go by a 15 extraction rate, which is recommended, multiply it with your room size, and you would know which exhaust fan capacity is right for you!

2. Type of Exhaust Fan

In Australia the most popular style is the ceiling exhaust fan. It looks neat and compact. However, you can also choose to go with a wall or window exhaust fan installation, based on your preference.

3. Consider different variations

Different exhaust fan models come with several variations. These include exhaust fans with built in LED bulbs or those with heat lamps. If you think that you don’t need too much light in the bathroom all the time, you can go with an exhaust fan with a light, instead of a separate light and thus save energy. On the other hands, if you looking for some warmth after the shower on those cold winter mornings, you can go for a heat lamp exhaust fan.

4. Look for Energy Saving Models

Not all exhaust fans are the same. Since bathrooms are used very frequently, you should consider investing in an exhaust fan that has low wattage, and thus costs you less to run. Also, if you don’t like the sound of your exhaust fan, going for a low wattage means it will take up less power and thus make less noise.


An exhaust fan in good working order will keep your bathroom mold free, dry and smelling pleasant.

The ideal place for an exhaust fan installation is exactly opposite from the place where the fresh air is flowing in. This facilitates cross ventilation. Exhaust fan installation is a complex job and should be done by a professional electrician.
