Volatile Organic Compounds (VOCs) are chemicals emitted as gases from various household products and materials, contributing to indoor air pollution. Common sources include paints, cleaning agents, furniture, and carpets. To reduce VOC levels indoors, opt for low-VOC or VOC-free products, increase ventilation by opening windows or using exhaust fans, and maintain a healthy humidity level. Additionally, storing chemicals properly and avoiding smoking indoors can help minimize VOC exposure and promote better indoor air quality.
