After this, the filter will simply not absorb any more gas. There is no difference in Protects only against gases and vapours. Therebreathing resistance, and it is unlikely that the user will be able Gas Filters/Cartridges are different kinds of gas filters/cartridges forto tell by smell or taste that the filter has become ineffective; the different kinds of gases. A gas filter/cartridge doesgas will just go right through the spent filter. This is why it is very NOT provide protection against particles. important to replace gas filters/cartridges before the end of the filter lifetime. This has to be done according to a time schedule based on the type and concentration of the gas or vapour.Combination Filters/ Protects against both particles and gases.Lifetime expires when either the particle component becomes Cartridges Different combination filter/cartridges are usedclogged and hard to breathe through, or when the time is up for depending on the gas or vapour present in the air. the gas component.Material Courtesy of SEA Group (Sundstrm)CLICK&COLLECT176 Call 132 100 or shop rsea.com.au FREE Pick-up from our Stores'
