• CERTIFIED: The highest-rated filter in the MIRA Safety lineup. The NBC-77 SOF is certified to EN 14387:2004+A1:2008 and rated A2B2E2K2HgSXP3DR — covering organic vapors, inorganic gases, acid gases, ammonia, mercury, phosgene (SX), and P3-class particulates with a REACTOR rating for radioactive iodine and methyl iodide. Actual tested particle filtration: greater than 99.999%, exceeding the EN P3 standard of 99.95%. Built for professionals, designed for everyone.
• ADVANCED: One filter that does what three typically can't. The NBC-77 SOF combines full-spectrum gas and vapor protection, coverage for a wide range of toxic industrial chemicals, and a DIN-rated REACTOR classification for radioactive iodine — including methyl iodide (CH3I). Compatible with full-face masks, mouthpiece assemblies, and powered air-purifying respirators (PAPR). Used by military personnel, CBRN specialists, and special operations forces worldwide.
• UNIVERSAL: NATO standard 40mm threading (Rd 40x1/7" per STANAG 4155 / EN 148-1), compatible with any standard 40mm full-face respirator. CE marked and compliant with EN 14387:2004+A1:2008 and EU PPE Regulation 2016/425. Filter dimensions: 110mm diameter, 85mm height, 335g. Operates reliably from -30°C to +50°C at up to 95% humidity.
• CONVENIENT: 20-year factory-sealed shelf life — most competing filters last 5 to 7 years. That means one NBC-77 SOF outlasts 3 to 4 replacement cycles, making it one of the most cost-effective options per year of protection on the market. Store between -5°C and +30°C at under 80% humidity. Shock and impact resistant housing. Expiration date clearly marked on the canister. Once opened, use within the rated service period.
