What is an essential benefit of using a makeup air unit in buildings?

Utilizing a makeup air unit plays a critical role in enhancing indoor air quality by introducing fresh outdoor air into a building. This is particularly important in enclosed spaces where indoor air can become stale or contaminated due to various activities, such as cooking, cleaning, or even just the presence of occupants. By supplying outdoor air, makeup air units help dilute pollutants and control indoor humidity levels, thereby creating a healthier environment for occupants. This benefit aligns with building codes and standards that often require adequate ventilation, making it essential for both comfort and health.

While energy efficiency, maintenance reduction, and sound insulation are valuable considerations in building design and operation, they are not the primary functions of a makeup air unit. The key focus remains on improving air quality, which significantly impacts the overall environment within the building.
