Replacement N99 Respirator Filters

These replacement N99 respirator filters are designed to provide a high level of protection against airborne particulate matter. The “N99” designation, certified by NIOSH (National Institute for Occupational Safety and Health), indicates that they are highly efficient.

• High Filtration Efficiency: N99 filters are rated to trap at least 99% of airborne particles that are 0.3 micrometers or larger. This makes them suitable for a variety of environments where fine dusts, mists, and other particulate aerosols are present.

• Non-Oil Resistant: The “N” classification means these filters are Not resistant to oil. They are intended for use in work settings free of oil-based particles, such as solid dusts from sanding, grinding, sweeping, or handling certain powdered chemicals.

• Secure Screw-On Design: Featuring a convenient screw-on (threaded) system, these cartridges are easy to install and remove, ensuring a secure and reliable connection to your compatible half-mask or full facepiece respirator.

• Versatile Application: These filters are a reliable choice for a range of professional and DIY applications, including woodworking, construction, and other dusty operations.
