The Threat

The blast is over in seconds. The fallout lasts 72 hours.

Most people think the explosion is the danger. It isn't. Radioactive particulates — invisible, odorless, sub-micron particles — settle into the air for 72 hours after detonation. You breathe 20,000 times a day. At 0.1 microns, standard filters don't touch them.

1
Detonation disperses radioactive isotopes
Fission products — cesium-137, iodine-131, strontium-90 — become airborne particulates within minutes of detonation.
2
Particulates settle for 72+ hours
Wind carries fallout miles from the blast zone. Ground zero survivors face the same respiratory threat as people 20 miles away.
3
Standard filters fail at sub-micron scale
N95 masks filter down to 0.3 microns. Radioactive particles are smaller. Only HEPA-grade CBRN filters rated to 0.1 microns provide meaningful protection.
4
Verva filters seal the gap
NATO 40mm CBRN-rated, 99.97% filtration efficiency at 0.1 microns. Fits all NATO-compatible full-face masks. 50+ year sealed shelf life.

  • Storage Case + Instructions
    Airtight protective case keeps filters sealed until deployment. Printed installation guide included.
How It Compares

Not all filters are built for this.

Most filters on the market were designed for industrial dust and paint fumes — not radioactive fallout. The differences matter when it counts.

"The only filter I found rated for actual fallout"
Spent three weeks researching after seeing the news out of the Middle East. Every other filter I found was industrial grade at best. These are the real thing — NATO certified, CBRN rated, and the 50-year shelf life means I'm not replacing them every few years. Bought the 3-pack for my family.

"Fits my mask perfectly, arrived fast"
Already had a NATO 40mm full-face mask. These filters threaded on perfectly — no adapter needed. Build quality is noticeably better than the cheap imports I tried before. The pre-filter pads are a nice touch. Ordered two more packs as backups.

"Bought for peace of mind. Now I actually have it."
I'm not a prepper. I'm a dad who watched the news for six months and decided I wasn't going to be the guy who did nothing. These filters are sealed, rated, and sitting in my go-bag. That's all I needed. Customer service answered my questions within an hour.

Common Questions

Answers before you buy.

These filters use the NATO 40mm thread standard — the most common thread pattern in the world. They fit any full-face mask with NATO 40mm ports, including the Verva Emergency Gas Mask and most military-surplus and civilian CBRN masks. If your mask has a different thread standard, check your mask's specifications before ordering.
Sealed: 50+ years. Once opened and in use: approximately 24–40 hours of active use depending on contamination levels. For a 72-hour fallout scenario, the 2-pack or 3-pack is recommended to ensure you have backup capacity. The pre-filter cotton pads extend active life by catching larger particles first.
CBRN stands for Chemical, Biological, Radiological, and Nuclear. These filters are rated for all four categories. The HEPA layer captures radioactive particulates down to 0.1 microns. The activated carbon layer absorbs chemical vapors including chlorine, ammonia, and organic compounds. Biological threats (bacteria, spores) are captured by the mechanical filtration layer.
No. These filters work with any NATO 40mm compatible full-face mask. However, a filter is only as effective as the seal of the mask it's attached to. A half-face or poorly-fitting mask will allow unfiltered air in around the edges. For full protection, a properly fitted full-face mask is required.
