Mask assembly kits provide a way to refresh your mask without purchasing the full mask! From Fisher & Paykel comes the Simplus Full Face Mask Assembly Kit, an easy–to–use full face mask offering a reliable fit and seal. Please note that this product is a mask kit, meaning it does not include a head strap. Straightforward and Effective Design Makes Nighttime Routine a Breeze A single clip locks the cushion to the frame, so separating the mask to clean is quick and easy. Plus, any size Simplus cushion can be used on the Simplus frame for your convenience. Cushion Technology Can Alleviate Discomfort Along Bridge of Nose Thanks to the RollFit seal of the cushion, you will notice less stress along the bridge of your nose compared to other mask options on the market.
