Neither we nor the manufacturer can guarantee that the outer packaging of the filter is 100% airtight sealed but it is only for transport, water and wear protection.Īttention! -We do not exchange filters if the alu-packaging looks not airtight during delivery, as filters that look airtight during (our)packing for delivery can change appearance during transport (inflate due to barometric changes) and look different to the receiver. When used as a particle (virus/dust) filter, the filter is good until it becomes difficult to breathe through it (it becomes clogged by particles) When using as protection from toxic gases it is recommended to change filters every day in contaminated battle area but when using against non-toxic gases such as tear gas or pepper spray, you can use the filter until you smell gas and to get out of contaminated area. The filter housing is sealed inside with 2 plastic plugs at each end that should be removed before use and can be put back when not in use Use: The protection time for the gas filter is at least 100 hours of use against chemical warfare agents but the recommendation (for soldiers) to change filters every day in a suspected contaminated area. In principle, the filter can be stored for almost any length of time since carbon Zytel-plastics and glass fiber paper do not age or rot if they are not in constant sun/heat or underwater.
