The cheapest way into current-generation bilevel
This is a Certified Pre-Owned AirCurve 11 VAuto — the current generation, at less than the previous generation costs new. Not a generic used machine:
If your prescription says bilevel, BiPAP or VAuto, this is the least you can spend with us and still get the newer machine — touchscreen, 26 dBA, and up to 15 L/min of supplemental oxygen.
The AirCurve 11 VAuto (Certified Pre-Owned) is a current-generation auto-adjusting bilevel (BiPAP) device for obstructive sleep apnea in patients over 66 lb. In VAuto it runs IPAP 4–25 and EPAP 4–25 cmH₂O with 0–10 cmH₂O of pressure support and a ceiling of 25, and it also runs S and CPAP modes. It has a touchscreen, an integrated heated HumidAir 11 humidifier, runs at 26 dBA, weighs 2.7 lb and accepts up to 15 L/min of supplemental oxygen. American Oxygen inspects, tests and reconditions each unit, installs a new filter, and backs it with a 1-year warranty by American Oxygen — not the manufacturer. A prescription is required. Ships from Doral, FL with free U.S. shipping over $99 and any compatible mask at 10% off.

Quick pick: this is the least expensive bilevel we stock and the newest hardware of the three — the trade is a 1-year American Oxygen warranty instead of 2 years from the factory. If a full factory warranty matters more than the price, buy the new AirCurve 10 VAuto. If your prescription sets a backup rate, none of that applies — you need the ST.

Frequently asked questions
What does Certified Pre-Owned mean?
Each unit is inspected, tested and reconditioned by our technicians, fitted with a new filter, and backed by a 1-year warranty by American Oxygen. Low hours, cleaned and sanitised.
Is the warranty from the manufacturer?
No. The 1-year warranty is provided by American Oxygen, not the manufacturer. If you want a full 2-year factory warranty, buy the new AirCurve 10 VAuto instead — it costs more but the coverage is longer and comes from the factory.
Why is the newer machine cheaper than the older new one?
Because this one is pre-owned and that one is sealed. The hardware here is a generation newer — touchscreen, quieter, four times the oxygen limit — but it has been used and reconditioned, and the warranty is ours rather than the factory’s. That trade is the whole reason for the price.
Does it have a backup rate?
No. A VAuto responds to breaths you take; it will not deliver a timed breath if you stop breathing. If your prescription sets a backup or respiratory rate in breaths per minute, you need the AirCurve 10 ST — call us before you buy this one.
Do I need a prescription?
Yes. A bilevel is a prescription medical device and the pressures come from your clinician. Send it over and we set the machine to those numbers at no extra cost.
Does it come with a mask?
No — masks are personal and sold separately. Add any compatible mask here and take 10% off that mask, or buy the machine on its own and choose later.
Can I travel or fly with it?
It’s a home machine with a humidifier, but it is airline-friendly and fits in a carry-on — PAP devices don’t count toward your carry-on limit on U.S. airlines. Empty the humidifier before you fly.
