Gas Mask Filter Shelf Life
One of the questions we get asked the most on the topic of gas masks is what is the shelf life of a gas mask filter. This is an excellent question, as your gas mask is really only as good as the filter you use with it.
Let's examine some possible scenarios that can impact shelf life of your gas mask filters, and look at some of the possible answers to this complex question.
Gas Mask Filter Packaging
The most important aspect of determining the shelf life of your gas mask filter is to examine the way it is packaged. If you purchased a vacuum sealed gas mask filter, like our NBC-381 Filter the shelf life of your gas mask filter is in excess of 20 years.
A loose packed gas mask filter that only has the intact seals could be good for 10 or more years, but the shelf life will be significantly less than a vacuum packed filter. The reason for this difference is the vacuum packed filter has in essence two layers of protection to keep out air and moisture. The active charcoal in the filter, if kept cool and dry, will last for decades before breaking down.
Gas Mask Filter Storage
If your gas mask filters are kept in a cool, dark, and dry environment you can count on them to have a much longer shelf life than if kept in a hot and humid location.
If you want to maximize the shelf life of your gas mask filter, purchase one of our vacuum packed NBC-381 filters. Keep it in the vacuum package and the shelf life is 20+ years.
Maximize your existing gas mask filters shelf life by storing them in a cool, dry, and dark storage location.
