Bath Fans: The Benefits of Adding an Exhaust Fan to Your Bathroom

Unsurprisingly, bathrooms tend to be amongst the most humid and damp places in a home, primarily due to steam from showers and a lack of ventilation.

However, when bathrooms have excess moisture this can cause a variety of problems such as mold growth and structural damage.

This makes it important that all bathrooms have a functioning exhaust fan to help remove excess moisture.

If one or more of your bathrooms currently does not have a working exhaust fan, here are just a few of the benefits a bath fan could provide you with.

Control Humidity

As we previously touched upon, the most important reason to have a working exhaust fan in every bathroom in your home is to help control humidity.

When moisture is not properly vented out of your bathroom after someone takes a bath or a shower, this can cause mold and mildew to grow in your bathroom.

Mold and mildew growth can be dangerous as it can cause:

  • Respiratory problems for you and your family
  • Structural damage to your bathroom walls and ceiling

While products are available that can help you get rid of this mold, installing a bath fan is the only way to prevent these problems from occurring in the first place.

Protect Your Paint, Wallpaper, and Walls

Not only can moisture cause mold to grow in your home, but also, excess moisture and humidity in your bathroom can wreak havoc on your paint and wallpaper.

Without the proper ventilation, your bathroom’s paint and wallpaper will begin to peel when exposed to moisture.

Additionally, moisture that is allowed to sit on your bathroom’s walls can even cause damage to the wallboard and can cause framing members to rot.

Installing a bathroom exhaust fan can then help to prevent peeling, and can save you money in the long-run.

Heat Removal

Exhaust fans can also be used as a heat removal tool during the hot summer months.

Hot air usually rises and pools at the ceiling.

Bath fans are then the perfect tool to pull out this hot air, which can help to reduce the temperature in the room by creating a continual flow of cooler air.

However, since bath fans make such effective heat removal tools, it is important to remember not to leave these fans running during the winter as they will remove warm air forcing your heater to work harder to maintain the temperature in your home.

Use bath fans sparingly in the winter in order to reduce energy bills.

Combat Odors

Another important reason to have a bathroom exhaust fan is that these fans can help to significantly reduce unpleasant odors.

When unpleasant odors occur in a bathroom, an exhaust fan removes them, quickly and easily.

This can also be particularly useful when cleaning with harsh cleaning chemicals and disinfectants, as a bath fan can vent these hazardous fumes quickly so that you and your family do not have to breathe them in.

Remember, you don’t have to sacrifice air quality for cleanliness.

Prevent Foggy Mirrors

While some people find it fun to draw designs and write messages on a fogged up mirror, having your mirrors fog up while you are in the shower can be annoying as you will have to wipe them down before you can start doing your hair and makeup, or shave.

However, a bathroom ventilation fan can help to prevent your mirrors from fogging up in the first place.

Before taking a shower, turn on your exhaust fan and steam from your shower will immediately be drawn up and vented out before it can cause your bathroom mirrors to fog up.


Convinced that you want to control humidity, stop your paint and wallpaper peeling, remove heat, remove odors and stop your bathroom mirrors fogging up?
