3M Air Purifying Respirator Cartridge KT777306301 — compatible particulate/chemical filter

Replacement cartridge KT777306301 from 3M is a combined air‑purifying filter designed for use with compatible 3M respirator facepieces. It integrates particulate filtration with chemical/organic vapor adsorption to reduce wearer exposure to airborne particles and selected gases or vapors when used according to the respirator manufacturer's compatibility charts and instructions. The cartridge is intended as a disposable element that can be installed and removed by hand for routine replacement in industrial, construction and maintenance settings.

Advantages

The combined particulate/chemical design allows a single cartridge to address both dusts and specified organic vapors, reducing the need to change separate filters. The cartridge is lightweight and shaped for straightforward manual installation on compatible 3M facepieces, and its disposable nature simplifies maintenance and inventory management. It is produced to 3M quality standards and intended for predictable performance when used within the specified service conditions of the respirator system.

Suitable for

• Industrial environments with mixed particulate and organic vapor hazards
• Construction and renovation tasks producing dust plus solvent or adhesive vapors
• Maintenance and repair work where both particulate filtration and chemical vapor protection are required
• Situations requiring a replaceable, easy-to-install cartridge for routine respiratory protection

Key specifications
