Mira Safety - CBRN Gas Mask Filter NBC-77 SOF 40mm Thread - 20 Year Shelf Life

The NBC-77 SOF 40mm gas mask filter canister, in combination with a full-face mask, mouthpiece assembly, or PAPR, reliably protects air passages against a wide range of harmful and highly toxic substances, including all known CBRN agents.

With a remarkable 20-year shelf life, this filter provides long-term storage solutions and compatibility with commonly available 40mm NATO threaded respirators. Whether you're dealing with organic gases, radioactive iodine, or toxic vapors, this filter meets EN 14387:2021 standards and provides 35+ minutes of Type B2 protection, like in the BioLab fire in Georgia.

Key Features:

• Compatible with standard 40mm NATO threaded respirators for easy interchangeability
• 20-year shelf life, reducing the need for frequent replacements
• Used by military personnel, CBRN specialists, and special operations forces globally
• Filters all known CBRN agents, including radioactive iodine, with a rating of A2B2E2K2HgSXP3 D R
• Certified by European agencies and marked with the CE symbol
• Exceeds EN 14387:2021 standards for protection against chlorine gas (Type B2)

New Color Options:

• Ranger Green: A muted green for woodland and mixed terrain, ideal for camouflage in military and tactical settings.
• Sandstone: An earth-toned color, perfect for desert or arid environments, offering concealment in sandy or rocky terrains.

Whether you're operating in dense forests, deserts, or urban environments, there's now a filter color option to suit your operational needs.

Gas Mask Filter Lifetime: The lifetime of the filter depends on the conditions of use and concentration of contaminants. Breakthrough times are tested according to EN 14387+A1, under conditions of 70% humidity and 30L/min flow rate, simulating medium-heavy work.

Gas Mask Filter Storage: Each NBC-77 SOF filter is sealed in plastic by the manufacturer. It should be stored unopened in a clean place at temperatures between -5°C and +30°C, with humidity levels below 80%. Sealed filters can tolerate conditions from -30°C to +50°C.

Disposal: After use, dispose of the filter according to the filtered substances and current waste treatment regulations. Follow local authority guidelines for disposal.
