Added security, wide variations.
 Chemical cartridge respirators are designed to remove toxic gas / vapor, which could lead to health disorders. The bonnet-style facepiece enclosure holds exhalation valve in a space between silicone facepiece body and front plastic housing. This consistently allows exhaled air to fill this space in between and it acts as a barrier to shut off possible inward leakage of toxic mist and atmosphere through the valve operation.
Type of chemical cartridge respirators and cartridge varies depending on the type of gas and its concentration level in the environment.

Chemical cartridge respirators can be used in the environment where toxic gas concentration level is less than 0.1%. Average gas concentration level for full-face chemical cartridge respirators must be less than 100 times (for half-face chemical cartridge respirators, it must be less than 10 times) of the exposure limit. If the duration of work per day is less than 30 minutes, average gas concentration level for full-face chemical cartridge respirators must be less than 300 times (for half-face chemical cartridge respirators, it must be less than 30 times) of the exposure limit.

Selection of cartridges
 Cartridges for use vary depending on the type of gas at the workplace. Make sure to choose appropriate cartridge. Call Koken or local distributor if cartridge for use is uncertain. Use supplied air respirator or SCBA if there exist more than 2 types of gas, or type of gas or gas concentration level at the workplace is unknown.
