Exhaust vents are openings designed to allow stale air, smoke, or fumes to exit a building or vehicle. They help maintain indoor air quality by removing unwanted pollutants and moisture, which can lead to mold growth and other issues. Commonly found in kitchens, bathrooms, and industrial settings, these vents are essential for proper ventilation. In homes, exhaust vents are often connected to exhaust fans that actively pull air out of a space. In vehicles, they help expel exhaust gases from the engine, ensuring safe operation. Proper installation and maintenance of exhaust vents are crucial for their effectiveness and safety.
