The cost of untreated sleep apnea
While you sleep, apnea can pause your breathing over and over, dropping oxygen levels and putting your heart under real strain. Press and hold below to see it play out.
Tap the button to toggle the simulation. Illustrative only, actual drops vary by person and event severity.
What changes when therapy is working
Commonly reported by people using an auto-adjusting CPAP with humidification, not a guarantee, but a fair picture of what consistent use tends to bring.
-
Quieter nights
A 26dB motor means the machine itself rarely disturbs sleep, for you or anyone sharing the room.
-
Less dryness
The heated humidifier is the detail that most often decides whether people stick with therapy.
-
Easier to stay consistent
Auto-Ramp and gentle pressure adjustment make the first few nights less of an adjustment.
Ready to use in minutes, no manual required
One button, no menus to learn.

Eight levels of heated humidity, and gentler exhaling
Dry throat and nasal congestion can make CPAP uncomfortable. The A20’s 8-level automatic humidifier keeps air comfortable, while Auto-Ramp gradually increases pressure as you fall asleep.
Pressure that responds to every inhale and exhale
The A20 adjusts pressure as you breathe, making exhalation easier and maintaining accuracy within ±0.5 cmH₂O. With both CPAP and APAP modes, it adapts to your preferred therapy.
Your therapy data, wherever you check it
Track up to 365 days of sleep data via SD card or WiFi. Data syncs to the cloud, letting you review your therapy from your phone, tablet, or computer.
Full face or nasal, your call

Before you decide
Do I need a prescription to buy this CPAP machine?
No, the A20 can be bought without a prescription in the UK, so you can start therapy right away. It's still worth talking to your doctor if you have a diagnosed condition.
Is it really quieter than an older CPAP machine?
Yes. The A20 runs at 26dB, well below most standard CPAP machines, which is one of the main reasons people give up on older devices.
Will the mask feel different from an older one?
Most people find the included mask lighter and lower contact than older mask designs. If it isn't right for you, you can switch between full face and nasal, or return it within 30 days.
What if I still can't get used to it?
Auto-Ramp, gentle pressure adjustment, and the heated humidifier are all built to ease the adjustment period. If it's still not working for you after that, our 30 day return policy and UK support team are there to help.
Is it hard to set up?
No. Attach the mask, plug in, and press the single start button, no menus or configuration needed. Most people are ready to sleep within a couple of minutes of unboxing.
Comfort, finally done right
Auto-adjusting pressure, heated humidification, and a mask made for you, all in one box.
