A bathroom exhaust fan helps ventilate the air in your bathroom. Not only does it eliminate unpleasant odors, it also keeps moisture out. This would prevent molds and mildew from feeding into your shower walls.
In purchasing your bathroom exhaust fans, you have to consider the size of your bathroom. If the toilet is a separate room from the shower it would require different air changes. A room without shower would require at least 8 air changes while the one with shower should have at least 15 air changes because of the moisture from the shower.
The number of air changes per hour multiplied to the volume (length X width X height) of the room would give you the air extraction value of the unit you should buy. The design and brand selected will then come down to your own personal taste, and how much you want to spend.
Modern bathroom exhaust fans also come with technological advancements like motion sensors which automatically turns on the power when someone walks in or turns on the lights. They could also come with filters that prevents allergies. Some of their designs make them discreet exhausts, some may even come with lights. One feature that is quite advanced is the capacity to set the exhaust to turn on a predetermined humidity level.
Upon selection, make sure also to consider where to place your air extraction unit as this could affect the size and design of the fan required for your needs. The air being exhausted out of the room should be equal to the air flowing into the room. That is why it is not advisable to place the device near a window as the ventilation will be less efficient to the rest of the room. It is best to place the exhaust at the ceiling connected to an outer vent.
Also make sure that your bathroom exhaust fan will not be exposed to water from your shower as this could be dangerous. It is best to have an electrician install it for you since there are obviously electrical skills required to do the job safely.
