The replacement Cushion for the Innomed Hybrid Universal Mask come as a single cushion in your desired size: small, medium, or large. All three sizes fit on the Hybrid Universal CPAP Mask.
The cushion covers the mouth and is a match for the Hybrid Universal Mask Nasal Pillows (sold separately).
Where do I find the size?
To find the size of the nasal cushion, turn the mask toward the user. With the elbow facing forward, hold the mask frame to view the curve at the top of the mask, where the frame and cushion connect. Large, embossed letters found between the nasal pillow openings and the mask frame will indicate the size of the nasal cushion.
