CPAP vs. APAP vs. BiPAP — what's the difference?
One pressure, or auto-adjusting
The most common machines for obstructive sleep apnea. APAP is the popular choice — it adapts all night so you don't have to.
- Built-in humidifier on desktop models
- APAP = AutoSet, Auto, AirSense, Luna G3
- Best value: Certified Pre-Owned
Two pressures, higher support
Prescribed when you need higher pressures, bilevel support, or find CPAP hard to exhale against. VAuto, ST and ASV are specialized bilevel modes.
- For higher-pressure or bilevel prescriptions
- Auto (VAuto), ST and ASV modes
- See the AirCurve 11 VAuto and Luna G3 25A
Note: We don't diagnose or set your pressure — that comes from your prescription. We help you buy the right genuine machine and set it up correctly.

BiPAP & bilevel — frequently asked questions
Do I need a prescription to buy a CPAP or BiPAP?
Yes — CPAP, APAP, and BiPAP machines require a valid prescription in the U.S. Masks, tubing, filters, and chargers don't. We can help you order once you have your Rx.
Can I buy a CPAP without insurance?
Yes. We're a cash-pay retailer — you can buy any machine outright, no insurance needed, and pay over time with Affirm at checkout.
Is American Oxygen an authorized ResMed dealer?
We sell genuine ResMed equipment (AirSense, AirCurve, AirMini). We are an authorized dealer of React Health (Luna G3, Transcend Micro). All machines are genuine and FDA-cleared.
What's the difference between CPAP, APAP, and BiPAP?
CPAP delivers one steady pressure; APAP auto-adjusts within a range; BiPAP delivers two pressures (inhale/exhale). Your prescription specifies which you need.
Which CPAP is best for most people?
An Auto-CPAP (APAP) like the AirSense 10 AutoSet or the authorized Luna G3 Auto suits most obstructive sleep apnea prescriptions. Call us if you're unsure.
Is a Certified Pre-Owned CPAP safe to buy?
Yes. Each Certified Pre-Owned machine is professionally cleaned, tested, and verified, with a new filter, and it's backed by warranty by American Oxygen. It's the same therapy for hundreds less.
What's included with the machine?
Machines typically include the humidifier, tubing, power supply, and filter; masks are usually sold separately so you get the right fit. Check each product page — mask and accessory needs vary.
Can I use my CPAP on a plane?
Yes. Our travel CPAPs (AirMini, Transcend Micro, Portable Luna) are approved for in-flight use — airlines allow them onboard as carry-on medical devices. Desktop CPAP and BiPAP machines are for home use.
Do these machines come with a humidifier?
The desktop CPAP and BiPAP models listed here include a built-in humidifier; travel models use a compact system. Confirm on the product page.
What mask should I get?
That depends on how you sleep and breathe — full-face, nasal, or nasal-pillow. See our guide to the best CPAP masks, or call us and we'll help you match a mask to your machine.
How long does shipping take, and is it free?
Free U.S. shipping on orders over $99; most machines ship within 1–2 business days. Local pickup is available at our Doral, FL showroom.
What if I need help setting it up?
Our Doral team helps with setup, pressure settings from your prescription, mask fit, and humidification — by phone, chat, WhatsApp, or in person, in English or Spanish.
Not sure which one is right for you?
Tell us your prescription and how you sleep — we'll point you to the right genuine machine and mask, no upsell. English & Spanish, from our Doral team.
