Most of the office buildings, industries, warehouses, factories, and other corporate facilities are equipped with heating, ventilation, and air conditioning (HVAC) systems. These HVAC systems work day and night; usually, they get replaced after decades of use. So, what happens is that these systems build up a layer of debris consisting of duct and other material inside the duct that is harmful to both the system and humans.
