The HC405 mask is the upgrade to the Aclaim 2. It features the same "Fit and Forget" technology that combines a unique foam cushion shape and headgear design for a comfortable, stable fit. The major difference between the Aclaim 2 and the HC405 is the hose connection which now swivels instead of being fixed upward and over the head.
