    Chronic obstructive pulmonary disease (COPD) affects approximately 44 million persons worldwide and is the fourth leading cause of death. Patients characteristically have symptoms consistent with chronic bronchitis and emphysema, but the classic triad also includes asthma. New developments in recent decades have led to the increased use of spirometry, an acknowledgment of airflow obstruction

    Similarly, three dust mask models had high penetration levels (8189%) for polydisperse aerosol particles (Rengasamy et al., 2008). Thus, the penetration results obtained in the study indicate that the filtration performance of fabric materials is similar in some aspects to some surgical masks to reduce the transmission of infectious diseases.
