When selecting the appropriate respiratory protective equipment, several factors must be considered. These include the nature and concentration of respiratory hazards, the availability of oxygen in the work environment, the duration of exposure, and the specific needs of the user.
Great masks need to give consideration to both high filtering efficiency and low respiratory resistance, reducing respiratory burden and improving wearing comfort. This is the original intention of the design and development of KINGFA High-breathability, Low Respiratory Resistance Mask.
Medical face masks are considered as medical devices and regulated by national medical device regulations. Regulations will define the legal obligations, to ensure that medical face masks provide the minimum level of protection against intended risks. Specific requirements by classification are cited in the referenced performance standards.
