Exhaust fans play a crucial role in creating a pleasant and healthy environment by maintaining optimal air quality, humidity levels, and temperature in various indoor environments.  Here is a breakdown of their positive functions:

1. Improved Air Quality

• Removes pollutants:  Exhaust fans help expel smoke, fumes, dust, and other airborne contaminants.
• Prevents respiratory issues:  By reducing mold spores, allergens, and pollutants, they help maintain respiratory health.
• Prevents buildup of harmful gases:  Especially in kitchens and garages, they prevent accumulation of harmful gases such as carbon monoxide.
• Removes odors:  They eliminate unpleasant smells from cooking, bathrooms, or cleaning chemicals.

2. Controls Moisture and Humidity

• Reduces dampness:  In areas like bathrooms and kitchens, exhaust fans help prevent excess moisture that can lead to mold and mildew.
• Protects building components and surfaces:  They reduce excess humidity which can damage walls, paint, wood, and insulation over time.

3. Enhances Comfort

• Reduces heat:  In hot environments such as kitchens and bathrooms, exhaust fans help vent hot air out, making the space more comfortable.
• Improves ventilation:  They help circulate air, especially in spaces without windows or adequate natural airflow.

So don’t be shy about flipping those exhaust fans in your home ON and be sure to leave them running for an adequate amount of time.  After showering, it is recommended that fans remain on for 30-60 minutes in order to clear out all the moisture.  In newer buildings, many of the exhaust fans are models that turn themselves on and off automatically as they are sensitive to temperature and humidity.  And don’t forget to keep your kitchen fan running after cooking to clear the air of all cooking odours.  That hum is keeping your precious home environment clean and comfortable!
