The Viva Nasal — it finds your forehead so you don’t have to
An automatic forehead adjustment that fits a wide range of head shapes on its own, minimal contact where masks usually leave marks, and an All Size Kit with Small, Medium and Large cushions in the box.
Authorized React Health · no prescription needed for a mask · free U.S. shipping over $99.
Why the Viva Nasal
The mechanism finds your forehead angle by itself, across a wide range of head shapes. Less fiddling at bedtime, and less pressure in one spot.
Designed to keep sealing whether you end up on your back, your side, or somewhere in between by 4 a.m.
Every cushion size in one box, so the first night is the fitting session and there isn’t a second order.
Three cushion sizes, all in the box
Try them, keep the one that seals.
Why this matters more than it sounds. The most common reason a CPAP mask gets abandoned is a bad seal, and the most common reason for a bad seal is the wrong cushion size. Cushion size has nothing to do with how big you are — it’s the shape of your face. Having every size in the box removes the guess, and the return.
Less contact, less to adjust
Where the comfort actually comes from.
A nasal mask seals around the nose, not inside it. It spreads the pressure over more surface than pillows do, which is why many people find it more comfortable at higher prescribed pressures — as long as you breathe through your nose while you sleep.
Will it fit my machine?
Standard connection — no adapter, no proprietary parts.
The Viva Nasal uses the universal 22 mm hose connection, so it works with standard CPAP and BiPAP machines. The one exception across our whole mask range is the AirMini, which needs its own mask-family setup pack — if that’s your machine, call us before you order.

Replacement cushions are sold separately — they’re the part that wears out, and they cost a fraction of a new mask.
Authorized React Health — and no prescription needed
American Oxygen is an authorized React Health dealer. This is a genuine React Health mask. Masks, cushions, headgear and tubing don’t require a prescription in the U.S. — only the CPAP or BiPAP machine does. A copy cushion never seals like the original, and on a mask, sealing is the entire job.
