Important Tips

Where do I find the size?

The FlexiFit HC405 Nasal CPAP Mask is a mask frame that comes with two nasal cushion sizes: small and large. The bottom of the mask frame is labeled with the mask name: HC405, representing the necessary mask frame needed if the user wears a size small or size large. When examining the front of the mask frame, the name is printed below the glider strap.

The FlexiFit HC405 cushion is replaceable, and it has an identifiable mark. To find the size of the nasal cushion, locate the flat bottom of the mask. Embossed in silicone, the user will see the word small or large. Depending on the word recorded on the bottom of the nasal cushion, the replacement cushion will need to correspond directly.
