Which colors are associated with the P100 filter?

The P100 filter is designed to provide the highest level of respiratory protection by filtering out 99.97% of airborne particles, including those that are oil-based. The colors commonly associated with P100 filters are purple or magenta. This color coding is part of the National Institute for Occupational Safety and Health (NIOSH) standard to help users easily identify the level of protection provided by different types of respiratory protection equipment.

Selecting this color association helps workers quickly identify that they are using equipment that meets stringent filtration standards necessary when working with hazardous materials such as asbestos. The other color options do not apply to the P100 filter classification and are used instead for different levels of protection, which helps ensure that individuals are adequately protected based on the specific risks present in their work environments.
