IMPORTANT NOTE for CHLORINE:

• Tested on type B gas such as Chlorine at 5000 ppm, the gas released during the BioLab fire in Georgia.
• NBC-77 SOF® filter exceeds the EN 14387:2021 standard, providing over 35 minutes of protection, surpassing the required 20 minutes.
• Rated Type B2 for advanced protection against chlorine and other hazardous gases, making it an ideal choice for incidents like the Conyers chemical fire.

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

The filters are produced with standard round threads according to STANAG 4155 (EN 148- 1)- Rd 40x1/7". The filter components are made of hard plastic. This results in a very robust product that is extremely durable against shock and impact damage in operational use.

We're excited to introduce two new color options for the NBC-77 SOF 40mm gas mask filter canister:
