Transform your gas mask into a reliable, fully functioning multiuse smoke hood with these VK-450 filters. Designed to overcome smoke & particulates (along with high concentrations of carbon monoxide), these advanced filters provide crucial hours of protection and clean air from some of the most common disasters faced by US citizens. Grab a few VK-450 filters for your family today!

Key Features:

  • Proven design provides comprehensive protection from a wide range of NBC threats, smoke and particulates.
  • Smoke respirator mask filter can be used in environments with as little as 19.5% oxygen.
  • Can be used at temperatures ranging from -40°С to +40°С.
  • Protection from ammonia, acetonitrile, hydrogen fluoride, hydrogen chloride, sulfur dioxide, hydrogen sulfide, hydrogen cyanide, phosgene, chlorine, chloropicrin, nitrogen oxides.
  • Each filter is vacuum-sealed and clearly labeled with its expiration date.
  • Long-lasting 13.5-year shelf life.
  • Manufacturer’s warranty ensures filters perform to specifications.

 

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:

QUESTIONS & ANSWERS

Ask a Question
  • I am aware that a P3 filter is required to block the coronavirus. Which one of your filters is P3?

    MIRA Safety filters (NBC-77 SOF, VK-450, DOTpro 320) are classified as "combined filters" and contain a P3 filter along with activated carbon. For those that don't know what P3 means, it is a rating for a particle filter that blocks 99.9999%+ of particulates. As viruses travel in liquid aerosols and particulates, this filter (when coupled with a full face respirator) would prevent the coronavirus from entering your breathing passages and eyes.

  • Does this filter contain any asbestos?

    No, it does not. 

  • If I combine the VK-450 with the NBC-77 SOF filter (one on each side), would I get the benefits of both?

    We recommend wearing one filter at a time as it's more comfortable and lowers the weight on your face. If you choose to wear two filters simultaneously, your filtration level would be equivalent to the filter that filters the least. In the case of the NBC-77 SOF and VK-450, the NBC-77 SOF does not oxidize CO, so the combo would still let CO into your lungs. 

  • Will these work with the MIRA Safety CM-6M Tactical Gas Mask - Full-Face Respirator for CBRN Defense?

    Yes, they will, as both are 40mm NATO threaded.

  • Once opened and in use, how long does this filter last before needing to be replaced?

    That depends on a few factors, including the contaminant type, concentration, breathing rate, along with atmospheric conditions. Specifically for CO conversion, this filter is rated for 15 minutes at 5000ppm, which is the standard for these types of filters.

  • How does the NBC-77 SOF compare to VK-450? In terms of protection from smoke due to wildfires?

    Both filters will work on smoke particles and certain gases/vapors that are produced when things burn. The VK-450, however, also contains an oxidizing agent inside of it that converts CO into CO₂, allowing you to breathe it out. It has been tested to convert CO for 15 minutes, at a concentration of 5000ppm.

  • In a few other answers, it was mentioned that these will fit the new GOST standard. Will these filters work on the Bayonet to GOST converter on the PMK-2. If not, will they work on the PMK-4,3 or S?

    These filters will work with any 40mm NATO threaded mask or NATO threaded converter. I am not sure if your converter meets the EN 148 thread standard. If it does, it should work just fine.

  • Can VK-450 filters work with GOST thread masks?

    These filters are threaded for 40mm NATO, so they cannot be threaded onto old-style 40mm GOST masks. They can, however, be used with masks that fit the new GOST standard which is 40x3.5mm, same as 40mm NATO.

  • Are these filters permitted to fly on airlines?

    That depends on where you are flying. Each country has different laws on what can and cannot be imported. As per US regulations, you are allowed to travel with a set of personal protective equipment for personal use.

  • Is this filter 40mm NATO threaded?

    Yes, it is.

  • How long are the filters effective once opened and installed on a mask?

    Filter use time depends on a few factors, including atmospheric conditions, contaminant type, concentration, along with your breathing rate. As a general rule of thumb, we would suggest having two filters per person per day for emergency evacuation purposes.

Good purchase

These filters are great because you can use your regular (mine is a CM-6M ) mask as a smoke escape mask. We have allot of Forrest fires in my area every fire season . I take the mask with me everywhere with a NBC-77 SOF Filter, 2 P3 particle filters and this VK-450 filter . Never know when you will need them but prepared for anything . The P3 I have used extensively in public and other places that my day takes me . The NBC-77 I had to use once so far (hope my extras get here soon ! ) and this VK-450 I haven’t had to use yet but it can save a life . In a situation like we saw in Paradise California or 9/11 and other situations our society has been Through if things like that happen again Having a proper carbon Monoxide and smoke filter could make a big difference not just for you but also those around you can you can help without getting smoke inhalation . This is something that would be most beneficial to add to your kit.

Multi purpose gas mask filter

I have the regular CBRN filters for my gas masks and have never seen any filters that are rated to work for smoke. So, I bought these for all of my gas masks. I don't know how well they work as I'm not going to test one at the price. But, if they work as designed, then the price will be well worth it. I like the claim that they are CBRN and smoke rated. I also, like the longer than 5 years storage life of these as well.
