In this study, the improvement in PM<SUB>2.5</SUB> concentration due to the Corona Virus Infectious Disease 19 (hereafter called as “COVID-19”) pandemic and the reduction of health hazards from mandatory mask-wearing were experimentally and theoretically investigated. Jeollabuk-do, a region with high PM<SUB>2.5</SUB> concentration nationwide and designated as an Air Quality Management Region (AQMR), was selected as the target area for this study. Unlike previous studies, the efficiency of masks in blocking PM<SUB>2.5</SUB> for various respiration patterns based on human behavior was experimentally evaluated using a medical ventilator (ADV-1000MK2) for the first time. The results showed that the blocking efficiency of PM<SUB>2.5</SUB> by masks ranged from 54.7% to 68.5% at rest, 56.0% to 70.0% during ordinary activities, and 67.1% to 80.6% during exercise. Compared to 2019, the year before COVID-19, the reduction rate of PM<SUB>2.5</SUB> concentration in 2020 during the pandemic was 26.9% in AQMR areas and 16.7% in non-AQMR areas of Jeollabuk-do, Korea. The deposition amount of PM<SUB>2.5</SUB> in the alveolar-interstitial (AI) region for one year in 2020 was 15.98 mg for men and 9.62 mg for women in AQMR, and 30.37 mg for men and 22.33 mg for women in non-AQMR. As a result of calculating the delay in allergic airway inflammation (AAI) days before and after COVID-19, it was estimated that in AQMR, men experienced a delay of 129 days and women 190 days, while in non-AQMR, men experienced a delay of 59 days and women 69 days.
