How clean is the air you’re breathing? The EPA has found that levels of pollution in indoor air is typically 2-5 times higher than air from outdoors, and in some cases up to 100 times higher.
Since the average person spends 90 percent of their time indoors these high levels of pollutants can cause severe issues when occupants are breathing them in constantly. This is such an issue that indoor air pollution has been ranked as one of the top five environmental risks to public health.
When the ductwork in a building is dirty it becomes a breeding ground for bacteria, viruses, fungi, and molds, which are then spread throughout the building’s air by the HVAC system. In places with occupants with weakened immune systems, such as schools and hospitals, the ductwork causes issues with infection control.
The CDC has even stated that one common source for Healthcare Associated Infections is from a contaminated ventilation system, and estimate that this has caused infections and complications in almost 2 million people.
