The Siesta Nasal — comfort without the bulk
A nasal mask stripped down to what it needs: a sleek low-profile frame, adjustable straps and a clear field of vision. The All Size Kit ships with every cushion size, so the fit is settled the first night.
Authorized React Health · no prescription needed for a mask · free U.S. shipping over $99.
Why the Siesta Nasal
No guessing and no second order. Try each one, keep the one that seals without you tightening the straps.
Low profile and out of your line of sight, so reading or watching TV with the mask already on stays possible.
Straightforward adjustment that stays where you put it — you fit it once rather than every night.
Every cushion size in the kit
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.
Simple, quiet, out of the way
What people say after the first week.
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 Siesta 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.

What’s included
- Siesta nasal frame and adjustable headgear
- Cushions in every size
- User guide
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.
