Dust and mold can be present and you may not realize it. Another component that can also be found in the ventilation system that you may not know or even see is bacteria. Yes bacteria can be found in the ventilation system when it is dry but primarily when bacteria is form when water is present in the air ducts or drip bans then this type of bacteria that is form can become a problem. According to an article by Indoor Environment Connections, when the bacteria is form it not only becomes a pathogen but also can be a endotoxins that can cause respiratory and ocular irritation, and can exacerbate asthma. The article also talks about how the bacteria might cause aerosolization. In addition the article also these actions are caused by three actions:
