The Fisher & Paykel Simplus full face mask incorporates three key components, the RollFit Seal, ErgoForm Headgear and Easy Frame, all designed to work in harmony. In combination, these components offer the comfort, seal and easy use that Fisher & Paykel Healthcare masks are known for. Recommended replacement annually, with cushion being replaced as needed for proper seal. Wipe down once a day with a damp cloth and wash in warm, soapy water once a week with a gentle soap.
