The HC405 Nasal Mask replacement headgear piece is the replacement for the FlexiFit HC405 Nasal CPAP Mask with Headgear. It comes in one size.
This replacement headgear piece is compatible with the HC405 Nasal Mask only. It will not fit with other Fisher Paykel CPAP masks.
Like all Fisher Paykel products, the HC405 Nasal Mask is latex free.
Play with the straps. With two sizes, the HC405A is built to fit anyone, but the mask itself will have to be tailored to fit your unique specifications.
You should replace your CPAP headgear about every three months. Over time, the straps will lose their elasticity, which will compromise the mask's ability to seal.
