React Health Viva Nasal CPAP Mask Fit Pack

The Viva Nasal Mask is a nasal, over-the-nose CPAP mask built around a forehead support arm that adjusts to your shape on its own, so you get stability without a padded cushion pressing into your skin. If you'd rather skip forehead contact altogether, our Siesta Nasal Mask rests its support arms on your cheeks instead.

We ship the Viva as a Fit Pack: one frame, one headgear, and three silicone cushions, Small, Medium, and Large, all of which fit the same frame. Try each size at home and keep whichever seals best; once you know your size, we also carry the Viva Nasal Cushion and Viva Headgear separately, so you don't need to buy a new Fit Pack to replace one part.

The Viva is magnet-free, so it's a safer nasal mask choice if you or someone who shares your bed has a pacemaker or another implanted device. The vent design diffuses air through the elbow instead of releasing it in one direct stream, which keeps exhalation quieter for you and anyone sleeping nearby. It's also built without natural rubber latex.

This is a nasal mask, so it's built for people who breathe through their nose during sleep. If you tend to breathe through your mouth, pair it with a chin strap or look at one of our full-face masks instead. React Health, formerly known as 3B Medical, makes the Viva, and like every CPAP mask we carry, it requires a prescription.
