What Does the 3M 5N11 Prefilter Protect Against?

The 3M 5N11 prefilter is specifically designed to protect against non-oil-based airborne particulates, including:

• Dust from construction and demolition
• Mists generated during spray painting
• Pollen and allergens
• Mold spores
• Fiberglass particles
• Grinding and sanding particulates
• Agricultural dust

Understanding the N95 Rating

The N95 designation is defined by NIOSH and indicates:

• N – Not resistant to oil; suitable for environments without oil-based aerosols.
• 95 – Filters at least 95% of airborne particles measuring 0.3 microns or larger.

This level of protection makes the 3M 5N11 prefilter ideal for a wide range of industrial and commercial applications.

How the 3M 5N11 Works

Step 1: Pair with a Compatible Cartridge

The 5N11 prefilter is designed to be used in conjunction with 3M gas and vapor cartridges, such as:

• 3M 6001 Organic Vapor Cartridge
• 3M 6002 Acid Gas/P100 Cartridge
• 3M 6003 Organic Vapor/Acid Gas
• 3M 6006 Multi-Gas/Vapor

Step 2: Secure with the 3M 501 Filter Retainer

To ensure proper placement, the prefilter must be attached using the 3M 501 filter retainer, which holds the filter securely over the cartridge.

Step 3: Enjoy Enhanced Protection

Once installed, the prefilter captures particulate matter before it reaches the cartridge, improving both filtration efficiency and cartridge longevity.

Compatible Respirators

The 3M 5N11 N95 prefilter is compatible with all 3M respirators that utilize the bayonet connection system, including:

3M Half Mask Respirators

• 3M 6000 Series Half Mask Respirators
• 3M 6500 Series Half Mask Respirators
• 3M 7500 Series Half Mask Respirators

3M Full Face Respirators

• 3M 6000 Series Full Face Respirators
• 3M 7800 Series Full Face Respirators

This compatibility ensures flexibility and convenience across a wide range of workplace environments.
