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:
