The CM-6M Tactical Gas Mask has a facepiece of tough bromobutyl rubber (CBRN-compliant) for maximum resistance to TIC/CWA contaminants. The full-face respirator’s inner mask is made from a special hypoallergenic compound that ensures excellent tightness and avoids exhaled air contact with the visor to prevent fogging. It also reduces carbon dioxide(CO2) content in the mask’s inner space, which together with its favorable inhalation/exhalation breathing resistance, decreases the physiological burden for the user—providing more comfortable and practical all-day use.

The integrated speech diaphragm ensures at least 95% intelligibility of speech, allowing for easy communication with other members of your party. The mask is equipped with a five-point rubber-textile head harness to ensure a snug and lasting fit.

The CM-6M CBRN gas mask is produced in one size. To ensure proper functioning, the user’s face must be smooth, free of facial hair, sideburns and other hindrances at the points of contact.

The tactical gas mask is compatible with the 3M Safety 6878 Spectacle Kit (sold separately), with simple installation for those who are vision impaired and prefer not to wear contacts. 

The filter is fitted to the mask by screwing to the left or right inhalation chamber. The unused chamber (without filter) is sealed with an inhalation chamber plug. It is necessary to ensure the plug is properly screwed and tightened. 

Inhalation chambers of the CM-6 mask are ONLY compatible with Rd 40 x 1/7” thread in accordance with the EN 148-1 standard.

Selection of a suitable filter depends on the type and concentration of anticipated toxic agent. The CM-6 tactical mask equipped with a TIC or CWA filter is only safe for use in an environment containing at least 19.5% oxygen. The principles of filter selection and application are described in the filter user guides.

The CM-6 tactical gas mask may be used in class 1 explosive environments only. The CM-6 mask meets all of the requirements for class 3 of the EN 136 standard. It’s a great choice for riot gear or as a riot control gas mask.

The CM-6 tactical gas mask must be stored in a dark, cool and dust-free place free from sudden temperature changes. The storage room should be ventilated regularly. Temperatures may vary between 10°C and 25°C within relative humidity up to 65%. Full face gas masks must not be exposed to radiant heat or sunshine. Fuels, solvents, lubricants and other inflammable substances, including chemicals, must not be stored with masks. Moreover, there must not be any electrical machines or appliances that produce sparks or discharges during operation (ozone creation).

Avoid deformation of the rubber parts of the facepiece and internal CBRN gas mask during storage.

    Turn Your Gas Mask into a Respirator for Smoke with the VK-450

    Wildfires are a constant threat to the Western United States—where thousands of citizens may be forced to evacuate at a moment’s notice through choking clouds of smoke and searing heat. Meanwhile, over 71,000 homes are lost in structure fires every year, according to studies from the National Fire Protection Association (NFPA). Yet, few own escape respirators or fire protection hoods.

    That means that fire poses an immediate threat to millions of unprepared American families. That’s where our VK-450 gas mask filters come in. 

    While most conventional gas masks and filters can protect you from hundreds of nuclear, biological and chemical threats, the VK-450 is one of just a few filters that can also protect you from carbon monoxide and minimize the risk of smoke inhalation. The VK-450 helps to convert CO into CO2, allowing you to breathe it out. So, instead of also keeping a single-use fire/smoke hood on hand, you can use your existing gas mask for smoke protection in case of a house fire or wildfire.

    Of course, these filters still provide full protection from NBC threats, and they sport a truly impressive 13.5-year shelf life. They come individually packaged and are easy to stack, store and manage. 

    If you’ve got a gas mask, or if you’re thinking about getting one, don’t overlook these flexible filters. Scroll down to check out the full details:

    Breakthrough time of a 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.



    The filters are sealed in plastic bags 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, the filters are 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.
