How effective are exhaust fans?

In rooms that are prone to create problems due to localized humidity, namely the kitchen, bathroom and laundry. For example the moisture content created as a result of cooking, hot water or even clothes dryers can create an extremely dramatic effect on the climate inside your home. When these particles are left to build up over a period of time the moisture starts to affect the walls, ceiling and tends to spread like a virus creating mildew and mold. An exhaust fan is a simple solution for this problem and oftentimes considered a life saver.

Exhaust fans are designed to excel hot or humid air out of a small area allowing fresh air to enter from elsewhere (oftentimes a vent). Then the warm air that is drawn out using an exhaust fan is then pulled through a ducting system and is expelled outside. 

Due to the steam and humidity that is built up in bathrooms, kitchens and laundries these fans are most commonly used in these areas, the range-hood over the cooktops in kitchens are one type of common kitchen exhaust fan.

There are some newly designed exhaust-fans have sensors that allow them to automatically activate when it senses that there’s steam in the room.

Exhaust fans have been proven to be effective in smaller spaces / rooms and is capable of moving approximately 2 cubic meters per minute usually provides sufficient ventilation. However, for larger areas industrial ventilation systems are much appropriate. The easiest way to identify what size and speed of fan is required is to figure out the volume of the room and after multiply it by the number of air changes that needs to cleared out.
