Exhaust vents are openings designed to allow air, gases, or fumes to escape from a building or appliance. They are commonly found in areas like kitchens, bathrooms, and attics, helping to improve indoor air quality by removing stale air and moisture. Proper ventilation through exhaust vents can prevent the buildup of harmful substances and reduce the risk of mold growth. These vents can be connected to various systems, such as HVAC units or kitchen range hoods. They often include filters to capture particles and may have fans to enhance airflow. Regular maintenance of exhaust vents is essential to ensure they function effectively and safely.
