Fisher & Paykel Simplus Full Face Cushion

This listing is the Fisher and Paykel cushion for the Simplus full-face mask. Official part numbers are 400HC579 for Small, 400HC580 for Medium, and 400HC581 for Large. Choose your size at checkout. The cushion is the only item in the box. A frame, headgear, and a machine are not included. Have the part number ready if you call about an order.

These cushions are for the Fisher and Paykel Simplus full-face mask. They are not cushions for Vitera, Evora Full, or other full-face masks, which use different parts. If your mask is not a Simplus, order the cushion made for that mask. Match the part number on the cushion you already use, or the size of your complete Simplus mask, before you buy.

Sizes in this listing are Small (400HC579), Medium (400HC580), and Large (400HC581). Use the size printed on your current Simplus cushion, or the size of the complete Simplus mask you already own, if that mask still fits well. This page does not invent a face-measuring chart. If you are between sizes, the fitting notes on the complete-mask page are the better guide.

The box is the size-specific Simplus silicone cushion only. It attaches to the Simplus frame you already have. Use the steps in your Simplus mask user guide. Headgear, a frame, a tube, and a machine are not included. This page does not invent a replacement interval. Inspect the cushion for tears or a flattened seal and replace it when it no longer seals comfortably.

This page does not quote a warranty term for parts 400HC579, 400HC580, or 400HC581, because an official Fisher and Paykel warranty statement written for these exact cushions was not on file when the listing was written. Cushions are wear parts. This page does not invent a coverage period. The manufacturer can confirm current terms. Have the part number ready if you ask about coverage.
