Types of Respiratory Protection | NPPTL | NIOSH | CDC
There are two main types of respiratory protection—air-purifying respirators (APRs) and atmosphere-supplying respirators (ASRs). Each respirator type provides a different level of protection based on its design.
Air-purifying respirators, which remove contaminants from the air. Employers must use the assigned protection factors listed in Table I to select a respirator that meets or exceeds the required level of employee protection.
