While most conventional gas masks and filters can protect you from hundreds of nuclear, biological, and chemical threats, the VK-450 is just a few filters that can also protect you from carbon monoxide and minimize the risk of smoke inhalation. This filter helps to convert CO into CO₂, allowing you to breathe it out. So, instead of 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. This mask is designed to be used at temperatures ranging from -40°С to +40°С. 13.5-year shelf life will guarantee long-term usage of the said filter. All in all, with the VK-450 CO/CBRN Filter, you can transform your gas mask into a reliable, fully functioning multiuse smoke hood.
