The M25 Tank Gas Mask, approved for use in 1962 and fielded in 1963, is essentially identical to the M14A2 Tank Mask but with the addition of a new microphone system, the M116G used with the AN/VRC-12-series radios.

How often you replace them should be determined by a change schedule based on exposures, manufacturer recommendations, proven mathematical models, manufacturer or NIOSH applications, or testing.A home for fans of the Metro book series, the games Metro 2033, Metro Last Light and Metro Exodus. Whichever method you use to estimate service life of respirator cartridges and filters should be conservative to allow for variability which can affect service life. Look for procedures and equipment for performing testing. Test equipment is available to assess service life.

Some cartridge manufacturers provide free software to help you choose the right respirator and determine its estimated service life. NIOSH offers a free MultiVapor™ Version 2.2.5 app for estimating the service life and breakthrough times for air purifying respirators. There are several mathematical models that can predict the breakthrough time and useful life of a cartridge. Storage and care – How a person stores and cares for their respirators can affect service life.

Site conditions – Variability of site conditions can affect service life.Cartridge variability – There can be some variability in the amount of material in a cartridge.Temperature – Higher temperatures can negatively affect the service life of cartridges.However, multiple contaminants in the atmosphere can significantly lower the life of a filter or cartridge. Number of contaminants – Most mathematical models and laboratory tests rely on a single contaminant.Humidity – High humidity will take up space in the absorbent that could be used by organic vapors, thus shortening the life of the filter or cartridge.Depending on the person, this can last anywhere between 8 to 14 minutes. There is a mine rescue training exercise that involves shutting off the air to your breathing apparatus and re-breathing the air in a collapsible bag until the air is gone. Physical fitness – Physical fitness and lifestyle can affect the amount of air a person requires.Exertion – A worker strenuously exerting themselves will increase their breathing rate and draw significantly more contaminant through the respirator cartridge.Several factors can influence the practical life of a respirator cartridge or filter, including: (Learn about The Basic Types of Respirators - And How to Select the Right One for Your Workplace.) Change schedules should be based on exposure estimates, manufacturer recommendations, mathematical models and tables, or thorough testing.
