"The Fisher & Paykel Vitera Full Face Mask - Assembly Kit is the cushion and the frame of the Vitera Full Face Mask without the headgear. It's a great way to freshen up your existing mask without the expense of buying the entire unit brand new. This headgear will turn this assembly kit into a convenient mask, easy and comfortable to wear. The Fisher & Paykel Vitera Full Face Mask - Assembly Kit Features: • RollFit Seal: The RollFit Seal is designed to deliver a precise fit and effective seal by automatically adjusting on the bridge of the nose. • Easy Frame: The Easy Frame – which fits all three seal sizes – now has a narrower profile than its predecessor. This provides a clearer line of sight while retaining seal stability. • Washable Diffuser: The innovative diffuser, which reduces noise and draft, is now washable and more durable than the original F&P Eson. • VisiBlue: Blue highlights incorporated into key mask components assist patients with mask use, orientation, disassembly and reassembly. This provides for simpler and more intuitive mask education."
