A P respirator is specifically designed to protect the wearer from airborne particles, particularly in environments where oil aerosols may be present. The key feature of a P respirator is its strong resistance to oil, which allows it to be effective in filtering out particulates in various industrial and hazardous environments where oil mist could be an issue.

The designation of “P” stands for “protection against oil,” indicating that the respirator can be used in situations where oil is present. This is crucial because certain types of respirators are not appropriate for oxygen's capacity in environments involving oil aerosols.

Additionally, while it is true that P respirators filter at least 95% of airborne particles, it is the aspect of strong oil resistance that classifies it and differentiates it from other respirators that do not offer this level of protection. Understanding these features is essential for selecting the appropriate respirator to ensure the safety and health of individuals in various work environments.
