Volatile Organic Compounds (VOCs) are airborne chemicals that can come from both natural and manmade sources. Monitoring VOCs is essential because exposure to harmful levels can impact health in both the short and long term. Some VOCs cause minor symptoms like eye, nose, or throat irritation, while others may lead to more serious health risks, depending on the level and duration of exposure. VOC sensors may detect chemicals from everyday human or animal activity. Although not all VOCs pose an immediate health threat, consistently high levels can signal poor air quality, making it important to monitor and adjust ventilation as needed.
