MIRA Safety VK-450 Smoke Carbon Monoxide Gas Mask Filter

MIRA Safety knows that a gas mask is only as good as the filter used with it, so they've designed the VK-450 Smoke and Carbon Monoxide Gas Mask Filter with rugged construction and superior usability. The VK-450 Gas Mask Filter attaches to your gas mask to provide clean air in the case of smoke, particulates, or high concentrations of carbon monoxide gas. These quality gas mask filters work in environments with as little as 19.5% oxygen and temperatures ranging from -40 degrees Celcius to +40 degrees Celcius. With a 13.5-year shelf life and marked expiration date, it's easy to stock up on these filters over time and store them for future preparation. Stay prepared with these VK-450 Gas Mask Filters for protection against smoke and carbon monoxide.

Features:

• Protects against a range of NBC threats, smoke, and particulates
• Additional protection against ammonia, acetonitrile, hydrogen fluoride, hydrogen chloride, sulfur dioxide, hydrogen sulfide, hydrogen cyanide, phosgene, chlorine, chloropicrin, nitrogen oxides
