Importance of Bathroom Ventilation

Ventilation is one of the most important aspects of a bathroom. Every house owner should think about proper bathroom ventilation to prevent humidity. There are various types of ventilation, like extract fan or windows. Both help improve ventilation in a home. These are also helpful in reducing mould development in bathrooms. The healthy home standard requires all bathrooms “to have mechanical extract ventilation, in addition to opening windows in habitable rooms.”

Determine the Correct Fan Size

Before installing a new bathroom exhaust fan, check the size of the fan. According to the Healthy Home Standards, the extract fan should meet minimum requirements either by exhaust capacity or size. It is recommended to consult a professional before buying or installing an extract fan. A trades person will guide you about which exhaust fan is right for you.

Choose Proper Fan Locations

Before installing a bathroom extract fan, pay attention to where the exhaust air will go. Air should be ducted outside and not into your house walls. Exhaust fans can be installed in a duct, on the roof or in a wall. Extract fan location will depend on the type of housing. It is important to look for the airflow pattern to choose the installation location. You should also consult with your trades person about where it is best to install an exhaust fan in your bathroom.

Reduced Condensation

Bathroom ventilation is helpful for reducing condensation. The best way to reduce condensation is to open a window. If your bathroom does not have a window then it will have an extract fan. After using the bathroom, you can leave the extract fan on for 10 – 15 minutes.


Prevent Mould and Mildew

Good ventilation helps in removing trapped moisture, it also helps in preventing mould development and mildew growth in the bathroom. With better bathroom ventilation, you will have lesser stress about your health.

Minimize Bacteria Growth

Bacteria growth in your house or bathroom can cause a lot of health issues. Dampness in the bathroom increases bacteria growth. Switching on the bathroom fan for at least 15 – 20 minutes can decease and eliminate a lot of problems.

Healthy and Safe

Bathroom exhaust fans are a necessity. They keep you safe and play an important role in odour control. They help in venting out the humid air.

In simple words, bathroom ventilation is a long goal. Improper ventilation can be harmful for your health and your home. Bathroom ventilation is good for fresh air. When you think about installing a bathroom fan, you are thinking about the health of your home. A good ventilated bathroom can have a positive impact on your walls and ceiling.
