Where They Overlap…

  • Surgical N95 Respirators must meet additional liquid resistance standards to be cleared for use in specific health care settings

Function Help reduce particles inhaled by wearer Help reduce particles both inhaled and expelled by wearer (plus fluid resistance) Help reduce particles expelled by wearer into environment (plus fluid resistance) Help block particles such as large droplets and fluids Daily use to block exhaled droplets
Application Can be used for respiratory protection when wearer might be exposed to particulate hazards Meant to be used during surgery and other tasks during which both of these are true:

  • Wearer requires respiratory protection … and …
  • Expelled particulates must be contained or fluid resistance is required
Can be used during surgery and other tasks to help protect patient, and/or when fluid resistance may be required This mask may help prevent droplets from entering but does not offer a reliable level of protection from airborne particulates. It is not considered respiratory protection. Covers user’s mouth, nose, and jaw providing a physical barrier.
