There are three ways in which a respirator mask filter and purify the air: particle filtration, chemical neutralization, and chemical absorption or adsorption. Particle filtration using a filter is to block organisms or substances that are larger than the pores in the filter. Once the filter becomes clogged, it must be replaced to remain effective. Particle filtration gas masks, however, will not help against chemicals and a different approach should be taken.
Chemical neutralization works by using chemicals to react with certain substances, such as chlorine or ammonia, to make it non-toxic. Different filters are available for any type of chemicals that need to be eliminated. respirator mask is ideal for industrial applications and filters encoded by the National Institute for Occupational Safety and Health, a branch of the CDC.
