You might not pay much attention to the fan in the ceiling of your bathroom. Maybe it turns on when you turn on the light, or it might have its own power switch, but what purpose does it serve?

A bathroom fan is actually your best ally in the fight against mold and water damage in your bathroom. When you take a shower, a lot of moisture is released as steam, and this will condensate and create a breeding ground for mold and other issues. The fan needs to function correctly to move that air outside however. If your fan is clogged by dust, it will not do its job, and the same goes if the fan doesn’t have a clear duct leading straight outside. If your fan was to deposit that steamy air into your attic or somewhere similar, you could soon experience mold issues there instead. This should be remedied as soon as possible.
