The MIRA Safety VK-450 filters fit NATO-standard 40mm filter threads and are compatible with both the CM-7M and CM-6M gas masks found on our website. This allows them to be used with other compatible full-faced masks, mouthpiece assemblies, or PAPR. They have a shelf-life of up to 13.5 years when kept in their original sealed condition.
In conjunction with compliant masks or respirators, the VK-450 filter provides an advantage over filters such as the NBC-77 filter that is only certified to protect against CBRN threats. The VK-450 not only protects against a wide range of harmful and toxic substances including all known CBRN agents, it adds the additional protection against smoke & particulates (along with high concentrations of carbon monoxide). Use for evacuating from house or wildfires, the filter converts carbon monoxide (CO) into carbon dioxide (CO2) which can be exhaled safely. This minimizes the risk of smoke inhalation, buying the user valuable time to get out of danger. In addition to the added smoke and CO protection, the VK-450 filter is also rated to filter out virtually every known Chemical, Biological, Radiological, and Nuclear threat. A summary of the filters specifications are found below.
