The NBC-17 SOF 40mm gas mask filter canister, in combination with a full-face mask, mouthpiece assembly, TAPR, or PAPR, reliably protects air passages against a wide range of harmful substances including 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.
IMPORTANT NOTE: Due to the shorter threads, the NBC-17 SOF Filter is NOT compatible with the MB-90 PAPR unit.

Breakthrough time of a gas mask filter is tested according to EN 14387+A1 at humidity 70% and flow rate 30 l/min, which is equivalent to the volume of air per minute used by an average person carrying out medium heavy work. The approximate lifetime (usage time) of a filter may, under normal conditions, calculated by comparing the concentration at the workplace and the minimum Dynamic Adsorption Capacity (DAC) for the filter.
Each NBC-17 SOF gas mask filter is sealed in a plastic bag by the manufacturer. Store the filters unopened in a clean place at even temperature, most appropriate at -5 to +30°C and relative humidity below 80%. Sealed filters tolerate also conditions of -30 to +50°C and RH below 95%. The storage period (month and year) for filters is marked on the filter label. Do not try to regenerate the filters. Never clean the filters with compressed air or compressed water.
After use, gas mask filters are considered special refuse. Make sure that they are disposed of according to the filtered substance (gases or particles) in accordance with current waste treatment regulations. If the product is to be disposed of, it should be dismantled from the respirator and disposed of as solid waste. Please see local authority regulations for disposal advice and locations.
How long can you use a filter
Filter use time depends on a few factors, including the contaminant type, concentration, breathing rate, along with atmospheric conditions. As a general rule of thumb, never reuse a filter (unless it is just a P3 filter for biological contaminants), and if you experience an increase in breathing resistance then it is probably an indicator that you should swap out the filter.

United StatesThis is my second time ordering this filter in a set a two. They worked so well in our riot testing I decided to order two more and yes I would recommend them to others if they live in or near a big city.
United StatesWell the best i can see is the filter is of good quality and packaged securely. I have not used the filter yet so I can not rate it's over all performance
United StatesFast delivery, great customer service, and top of the line quality! What else can I say? Thankyou Mira Safety! :)
United StatesFast delivery great packaging and great quality and price what’s not to like !!
