How does source reduction benefit indoor air quality?

Source reduction significantly benefits indoor air quality by diminishing the potential for pollutants to enter and accumulate in indoor environments. When pollutant sources are minimized or eliminated, the overall exposure risk for occupants is reduced. This is essential because many indoor air pollutants can arise from common household items, building materials, and activities. By addressing these sources proactively, individuals can help maintain a healthier indoor atmosphere, which is crucial for the well-being of everyone who uses the space.

In contrast, the other options do not accurately reflect the benefits of source reduction. Maximizing pollutant introduction would exacerbate indoor air quality issues, while minimizing cleaning requirements does not necessarily align with improving air quality directly; rather, it might suggest a lack of engagement with the cleaning processes needed to maintain air quality. Similarly, while increased ventilation can help manage indoor air quality, it is not the same as source reduction, which focuses on limiting the initial sources of pollutants rather than relying solely on ventilation to mitigate their effects.
