Summary:All of a predetermined number of original air purifying air-oxygen generating canister units have a useful life of substantially the same number of hours. Each unit is designed to generate oxygen at an initial rate of at least half of what is required to support life in a closed chamber in which the canisters are to be used, but at a rate less than required. First, two of the canister units are inserted together in an air-circulating system in the chamber and then the remaining canister units are connected in the system in succession at time intervals substantially equal to said number of hours divided by the number of original canister units. One of the two original units is replaced by a replacement unit at a time before the expiration of said number of hours substantially equal to one of said time intervals. Each of the remaining original units in succession then is replaced by a replacement unit at substantially regular intervals just before the expiration of the life of the unit being replaced.
