Building Inspector Practice Exam – Comprehensive Study Guide and Practice Test

Using air filtration systems and ensuring proper ventilation significantly improves air quality in buildings. Air filtration systems work by removing contaminants such as dust, pollen, and smoke from the air, which can help mitigate respiratory issues and allergies. When combined with proper ventilation, these systems ensure that fresh outdoor air is circulated within the building, reducing the concentration of indoor pollutants. This combination is critical for maintaining a healthy indoor environment, as it helps to address sources of indoor air pollution and brings in clean air.

Utilizing air filtration systems and good ventilation practices is essential in both residential and commercial buildings, especially in areas prone to air quality issues. Effective filtration systems vary in their efficiency levels, but those rated with higher Minimum Efficiency Reporting Value (MERV) ratings can capture smaller particles, thereby providing even better air quality. Proper ventilation can also dilute indoor air pollutants by introducing fresh air, thus contributing to overall comfort and health for occupants.
