The FlexiFit HC432 Full Face CPAP Mask Assembly Kit combines the "under chin" design with the foam cushion insert and silicone seal for seal and stability. This mask is available in four sizes, select the size needed when ordering.
The FlexiFit HC432 mask frame does not have an identifiable size because it offers a universal fit for all four cushion sizes created for the HC432 Full Face CPAP Mask.
To find the size of the cushion, turn the mask to look at the flat bottom of full face cushion. Large embossed letters spell out the words "S M A L L," "M E D I U M," or "L A R G E." The words are found near the rim connecting the mask frame to the full face cushion.
The silicone cushion and foam insert are both replaceable. To find the size of the foam insert, pull the insert out of the cushion. Hold the insert as if preparing to place the insert inside of the cushion. A small, embossed letter is recorded at the peak of the insert, where the nose connects to the foam material.
