Nasal Cushion (with Silicone Seal) for Aclaim 2 & FlexiFit 405 CPAP/BiPAP Masks

This replacement Foam Cushion & Silicone Seal Pack is designed for all Aclaim 2 (HC401) and FlexiFit 405 (HC405) Nasal CPAP and BiPAP Masks. The cushion uses FlexiFit foam / air technology to conform to most noses and facial features. Aclaim2 and FlexiFit 405 masks use a single frame size so either pack size can be used regardless of the size currently being used on your mask.
