The activated carbon in a hollow, triple filter shows, under normal storage conditions, i. e. at a temperature of 21°C and 60 % relative air humidity, a decrease in the capacity for retention connected with the changed water content of the carbon. This loss of activity occurs during the first two weeks and subsequently remains practically constant even if storage lasts 6 months
