Air ducts are the paths traveled by the air, meaning it’s optimum for the traveling air to be as clean as possible, because the air can pick up any particles or debris in the ducts and carry it straight to your lungs.

Having clear air ducts can contribute to good indoor air quality (IAQ), which the US Environmental Protection Agency (EPA) states is a prime concern in relation to pollutants these days. The EPA is referring to the air quality around buildings and structures, more specifically as it pertains to the comfort and health of their occupants.

The health effects from indoor air pollutants can show up soon after you are exposed or even years later. While the scientific community recognizes common indoor air quality pollutants can have harmful consequences, it can’t pinpoint how long of an exposure or what concentrations are necessary for specific health problems.

Add to the mix that different people react very differently to these exposures. With all this uncertainty, it’s a better scenario to avoid the pollutants altogether as much as possible.
