bathroom dehumidifier vs exhaust fan
Written by Jenny Molin

Bathrooms often have a lot of condensation and moisture due to being often wet most of the time.

What Are Exhaust Fans and Bathroom Dehumidifiers

The primary distinction between a dehumidifier and an exhaust fan is how they operate. An exhaust fan essentially circulates air around your house or basement.

They are far less complicated than dehumidifiers and therefore can typically be installed by anybody. An exhaust fan is an ideal choice if the bathroom is humid while showering. While running an exhaust fan in the bathroom can cause outdoor air to leak into other sections of your house, this won’t be an issue because you’ll only use it for a few minutes.

Dehumidifiers are far more complicated, and they function by pulling air through the device, where it condenses on cooling rods to remove the humidity. The air is then released back into the area. This technique does not truly deliver fresh air inside your house because it only dehumidifies the current air. A dehumidifier should be used in the bathroom if it is constantly humid. The use of a dehumidifier inside your bathroom will have no negative consequences for the rest of your house.

Disadvantages of Exhaust Fans

The great news is that certain dehumidifiers allow you to set up a permanent drainage system. This is accomplished by connecting the dehumidifier to a pipe and letting it pour into the sink.

4. Noisy

Which One Is Right for You?
