When they are in mint condition, the filter cartridges are vacuum-packaged and
capable of being stored for two years (see durability date on the filter cartridge).
Defective vacuum packing or an overshot durability date cannot protect the filter
cartridge adequately from environmental influences in storage. Under such cir-
cumstances, the filter cartridge can be saturated before it is used.
Only use filter cartridges with undamaged vacuum packing.
Do not use filter cartridges with overshot durability date.
