How does a Gas Mask Filter Work?

Gas mask filters are one of the main components of a gas mask. Activated charcoal or oxidized charcoal is used in the majority of filters. Toxins passing through the charcoal become attached to perforations within the filters, preventing them from entering the gas mask.

There is a manufacturing date on all these filters. The majority of them have a five- to 10-year shelf life, although high-end ones can last up to 25 years or longer with proper storage. The filter’s medium must keep separated from the outside environment. Otherwise, it may absorb impurities from the air. This may reduce its efficiency.

Key Points to Know About Gas Mask Filters

Before investing in a gas mask and gas mask filter, there are some important factors to consider:

  1. Filters can vary in which masks they fit. Most gas masks have threading that fits a 40mm filter, also known as the NATO 40mm standard.
  2. Most new filters manufactured during the past decade include a nuclear, biological, and chemical (NBC) rating as well as a chemical/biological agent-riot control agent (CBA-RCA) rating to ensure that you can use the filter in the appropriate environment. 
  3. The manufacturing date of the gas mask filter is essential to check. All filters have a visible validity period. This is important to follow to ensure proper filtration for your gas mask.
  4. Never reuse a filter exposed to mercury and radioactive compounds, which can be extremely harmful to the body.

Now lets look at the best and most popular NBC and chemical, biological, radiological and nuclear defense (CBRN) filters in the market.
