How to Choose the Right Exhaust Fan

With summer dwindling and the colder months nearly on us, our thoughts are naturally moving away from cooling to heating. And one of the most important things to consider is your bathroom heating and exhaust. While keeping warm in the bathroom is paramount to your comfort, when warm air and moisture meet, that can spell disaster. As a result, having the right exhaust fan for your bathroom is incredibly important. Today we are going to discuss how to choose the right exhaust fan for your bathroom.

Profile Panel 4Why Do I Need a Bathroom Exhaust Fan?

Whether or not you like long, luxurious baths and showers, your bathroom needs an exhaust fan. Steam, heat and humidity combine in the bathroom, raising the risk of health issues and damage to the bathroom. 3-in-1 bathroom exhaust fans add ventilation, reduce humidity, and improve airflow and air quality. A bathroom fan can help prevent mould and mildew, which not only damage the bathroom but are dangerous to your health. Children, those with asthma, and elderly people are especially vulnerable when it comes to mould and mildew.

But humidity and moisture cause far more problems than mould and mildew. They can cause water damage to bathroom fixtures and mirrors. If left untreated, the damage can go further, damaging walls, paint and tiles, and even causing wooden frames and doors to warp. As a result, investing in a good bathroom 3-in-1 exhaust fan will save your health and money in the long run.

1: How Do I Choose the Right Capacity Bathroom Fan?

Just like choosing the right sized air conditioner for a room is important, choosing the right sized exhaust fan is important. A fan that is too big will be noisy and uncomfortable, especially if you purchase a 3-in-1 bathroom exhaust fan that features a heater. And, of course, an exhaust fan that is too small will have very little effect in your bathroom.

When deciding the size of your exhaust fan, you need to measure the size of your bathroom in metres. You will need to measure height, length and width. Then you need to multiply your measurements. For example, a bathroom that is 3m long by 2m wide by 3m high, you would get 18m3. You then multiply it by how many air changes your bathroom needs.

A bathroom without a shower needs around 6-8 air changes per hour. A bathroom with a shower needs 15-20 air changes. This final number will give you the capacity you need for your bathroom. So, assuming our example needs 15 air changes by hour, we get 270m3/h. As a result, we would look for 3-in-1 exhaust fans with a capacity of at least 270m3/hr.

2: Installing the Right Exhaust Fan

Most bathroom exhaust fans are installed via the ceiling. And high quality exhaust fans, like those from Martec, come with the appropriate extras for installation. It is always recommended you have a qualified electrician install any electrical appliances, especially in the bathroom environment.

Choosing the right location for your exhaust fan is important as well. You need to vent air outside your home not inside. Far too many people vent moist, warm air into attics and similar spaces, which is just moving the problem to a different room. When choosing your bathroom exhaust fan, you need to consider both capacity and location to ensure you get the most out of your fan.
