What is the goal of dilution as a control strategy?

The goal of dilution as a control strategy is to reduce the overall concentration of contaminants in a given space. This method involves introducing fresh air into an environment to mix with potentially polluted air, thereby decreasing the concentration of harmful substances, such as volatile organic compounds (VOCs), particulate matter, or other pollutants.

By diluting the contaminated air with clean air, the total amount of these pollutants is effectively lowered, improving indoor air quality and reducing health risks associated with long-term exposure to high levels of contaminants. This approach is particularly useful in situations where it may be impractical or too costly to remove all contaminants through filtration alone.

In contrast, increasing the concentration of contaminants, eliminating the need for filtration, or stabilizing temperature are not aligned with the primary objective of dilution, which seeks to create a healthier environment by lowering harmful levels of air pollutants.
