HÖUM : The Pros & Cons of Exhaust Fans

Exhaust fans are mechanical ventilation devices that are used to improve ventilation and remove stale air, moisture, and odors from enclosed spaces, such as bathrooms, kitchens, and laundry rooms.


They work by creating negative pressure that pulls the stale air out of the room and expels it outside. Exhaust fans are typically installed on a wall or ceiling and require electricity to operate. By installing exhaust fans, the unwanted warm air, odors, and moisture in these rooms can be transported outside easily.

While they offer several benefits, they also have some drawbacks. Here are some of the pros and cons of installing exhaust fans:
