Biological Contaminants in Ventilation

Biological contaminants in ventilation systems are microorganisms like bacteria, viruses, mold spores, and other biological substances that can enter and circulate through the air. These contaminants can originate from various sources such as outside air, occupants, pets, or moisture build-up inside ducts and filters. If not properly managed, they may degrade indoor air quality, potentially causing health issues like allergies, respiratory infections, or asthma flare-ups. Regular maintenance, proper filtration, and humidity control are essential to minimize biological contaminants and ensure a healthier indoor environment.
