Radiant Lighting: Your Guide To Extractor Fans

Managing humidity in the home can be tricky. We’ve asked the Radiant Lighting team to help us out with all the FAQ’s to understanding extractor fans and how these work best in interior design.

What rooms in the home are suitable for extractor fans?

Any bathroom, kitchen, or utility room can benefit from an extractor fan.

What are the benefits of installing an extractor fan?

Installing an extractor fan offers a multitude of benefits. They expel both odours and moisture out of the space. The bathroom, in particular, is a wet zone in the home. When steam rises from a hot shower or bath, water droplets settle on the cold surfaces, promoting the growth of mould and bacteria. These damp surfaces, be it the mirror, shower door or taps, are also prone to mildew build-up. No mildew means a quicker and easier cleaning routine. In the kitchen, an extractor fan can be used to eliminate any moisture from cooking or unpleasant odours. Utility spaces and garages can also use extractor fans to remove any pollutants that may linger in the air.

How does an extractor fan work?

The moisture in the air is sucked out through a duct leading to a vent opening.

How do I install an extractor fan?

Installation is best completed by a professional, especially when fitting in a wet zone.

What’s the most effective way to use an extractor fan?

To ensure all moisture and odours are removed, it’s recommended that you don’t switch the fan off the moment you exit the bathroom. Leave it on for at least a few minutes after you leave the room.

How do I know if my bathroom needs an extractor fan?

If mold or dampness is building up in a space, then an extractor fan is a must, especially if there is no other form of ventilation. If your space already has a window but could use extra ventilation, then an extractor fan will guarantee a mechanical expulsion of moisture and odour.

How can I work out what size extractor fan to get?

In order for the fan to work effectively, it needs to meet the minimum capacity required by the space. You can work this out by calculating the volume of the room (length x width x height) and then multiplying this number by the recommended air changes required. Bathrooms generally need about 6 air changes per hour. Once you have this figure, you can select a fan that will suit your specific room size.
