Everyone loves taking long hot showers that transform the bathroom into a sauna, but what many people don’t know is that the humidity and steam that’s created as a result of the hot water running for extended time period can compromise the air quality. Moreover, the humidity enables fungus to thrive, and it can lead to mildew and mold problems. In order to prevent all of these unnecessary complications, and to make your shower time more comfortable and safe, you might want to consider getting an exhaust fan. Exhaust fans effectively get rid of the moisture that’s created in the bathroom, thus helping prevent the growth of bacteria and eliminating unwanted bathroom odor.
Exhaust fans are designed in a way that they do not disturb the bathroom’s layout scheme and modern models are usually very quiet-running, unlike fans in the past which used to sound like an Apache landing on your roof. They’re also very easy to install. All you need to do when you are looking to buy exhaust fans is consider the size and features so that you get a model that offers enough ventilation for your bathroom. Fans are rated according to the cubic metres per hour of air they can move, so the larger your bathroom is, the larger the fan you’ll need to exchange the air efficiently.
In order to get an idea of the size of the fan you need, figure out how many square metres your bathroom is. Then, measure the height of the walls. Let’s say the bathroom is 5 by 5 meters, so 5 x 5 = 25. Then, the height of the walls is 3 metres, so 25 x 3 = 75. So, the bathroom is 75 cubic metres. In order to be effective, the bathroom fan should be able to replace the room’s air about 7.5 times in an hour, so 75 / 7.5 = 10. This means that you need a fan that’s rated 10 m3/h.
When looking to buy exhaust fans, you’ll come across many different models with different features. For instance, some have a ceiling light, which means that once you flip the bathroom light on, the fan will be activated as well. Some fans can be activated to pre-set humidity levels, while others have a motion sensor that activates the fan if someone walks into the bathroom. Other models, on the other hand, have a timer switch, allowing you to run the fan for a pre-determined amount of time. Some models go as far as having allergen-reducing filters.
