How to buy a ResMed CPAP: Models, real 2026 prices, and where to order

It's 2 AM. Your partner just elbowed you awake because you're snoring again.

Your doctor mentioned CPAP therapy three months ago, but you never scheduled the sleep study. Now you're online, trying to buy a ResMed CPAP before you spend another night like this.

You're not alone. A 2024 study in Respiratory Medicine estimated that 83.7 million adults in the US. suffer from obstructive sleep apnea. That's about one-third of the adult population. Most end up in the exact same place you are now.

Most buying guides only list technical specifications and that's it. This one is different. Here we explain what your medical prescription should say, we break down how much the AirSense 10 and AirSense 11 actually cost in 2026, and we help you figure out which one best suits your lifestyle.

Why can't you just add a ResMed CPAP to your shopping cart?

This is the first thing that confuses people. A ResMed CPAP is not like a common humidifier or a white noise machine. The FDA classifies every CPAP, APAP, and BiPAP device as a Class II medical device. That puts it in the same regulatory category as motorized wheelchairs.

The Academy of Sleep Medicine endorsed this classification in 2018, and the requirement for a medical prescription remains in effect.

Without a prescription, no legitimate dealer can send you a machine. This applies even if you have been using CPAP therapy for years. If you skip this step, you risk receiving a machine configured with incorrect pressure. Inadequate pressure means the device will do almost nothing for your sleep disorder.

Fortunately, getting an evaluation doesn't have to mean spending weeks on a waiting list for a lab sleep study. Home sleep apnea tests, ordered by your primary care physician, now allow many adults to qualify for a prescription in a matter of days. Once you have that order in hand, choosing a model and placing your order will only take a few minutes.

ResMed AirSense 10 vs. AirSense 11: What really changed?

Most people looking for where to buy a ResMed CPAP end up choosing between two machines: the AirSense 10 AutoSet or the newer AirSense 11 AutoSet. Both offer the exact same core therapy, but the differences are noticeable in daily use and your wallet.

Design, screen and daily use

The ResMed AirSense 10 uses a rotary dial and a small front screen. It is simple, durable and familiar to anyone who has used a CPAP for years.

On the other hand, the AirSense 11 replaced that dial with a full-color touchscreen. It also adds Care Check-In and a built-in Personal Therapy Assistant, two tools designed to guide new users through their first few weeks of treatment.

Important detail: The AirSense 10 and AirSense 11 do not share parts. Water tanks, tubes, and power supplies are model-specific, so if you decide to upgrade later, you'll have to buy new accessories.

Price and what each includes

Price is where the decision gets real. The price of the ResMed AirSense 11 AutoSet is usually between $1,050 and $1,100 for the machine with its HumidAir humidifier. The price of the ResMed AirSense 10 is usually lower, typically between 

$600 and $900 with the humidifier included, depending on the vendor and package.

None of these prices include the mask, which you will have to buy separately depending on how you breathe and sleep. The standard tube, filters, and travel case are also usually charged separately, unless you choose a bundle kit.

How much does a ResMed CPAP really cost in 2026?

The number you see on the price tag is rarely the total cost. Here's what actually shows up at checkout:

● The price of the ResMed AirSense 10 for the AutoSet model with humidifier typically ranges from $600 to $900.

● The price of the ResMed AirSense 11 is higher, generally between $1,050 and

$1,100 for the same configuration.

Both figures assume you are purchasing the equipment directly rather than renting it through a durable medical equipment provider.

Health insurance can substantially change these figures. Most private plans and Medicare Part B cover a portion of CPAP costs. To do so, you will need to first register an approved sleep study and a medical prescription. Many plans also require a 90-day compliance period; that is, they track your hours of use before agreeing to cover the purchase instead of the rental.

FSA and HSA (flexible spending or health savings accounts) funds typically cover CPAP machines, masks, and supplies as qualified medical expenses. This can significantly alleviate the impact of the initial payment if you are paying out of pocket while insurance processes your claim.

What most ResMed CPAP buying guides don't tell you

● Humidifiers are not interchangeable: The water chambers of the AirSense 10 and AirSense 11 have different shapes. If you are switching from the 10 to the 11, factor in a new tank and tubing instead of trying to reuse the old ones.

● Renewal requirements: Although a CPAP prescription is often written as open-ended or permanent, your insurer may require a new sleep study or download of your compliance data every one or two years before authorizing the replacement of your supplies.

● Battery Use: The AirSense 11's lower power draw (65 watts) makes it much easier to operate with a portable battery bank when you go camping or travel to places without electricity, something the AirSense 10's 90-watt adapter often struggles with.

● Flight Friendly: Both AirSense models meet FAA requirements for in-cabin use, so you can use your machine during an overnight flight instead of checking it in luggage. Always check your airline's carry-on rules before traveling.

● Noise Level Matters: The noise level is more important than people think. Both machines operate at around 27 decibels, which means they are quieter than the 30 decibel average of other CPAP devices according to testing by Sleep Foundation.

Where to buy a ResMed CPAP online safely

Knowing where to buy a ResMed CPAP is as important as the model you choose.

Always look for an authorized ResMed dealer who has the prescription verification process built into their checkout platform. This single requirement immediately rules out gray market sellers. Bypassing the prescription step is illegal in the US and, further, usually means you will receive a machine without the official manufacturer's warranty.

Check the return window and warranty time before ordering. ResMed backs their machines with a standard manufacturer's warranty, but only authorized dealers can make it valid if something goes wrong.

Also, be sure to confirm what the bundle includes before finalizing your purchase. The listed price for the AirSense 11 AutoSet typically covers the unit and humidifier; masks and heated tubing are typically billed separately.

Frequently Asked (FAQ)

Do I need a prescription to buy a ResMed CPAP machine?

Yes. The FDA classifies CPAP machines as Class II medical devices, so a valid prescription is required before any authorized vendor can ship one to you. You must first undergo a sleep study (either in a lab or at home), and your doctor will use those results to establish the pressure range you need.

What is the actual price difference between the AirSense 10 and the AirSense 11?

The AirSense 10 AutoSet typically costs between $600 and $900 with a humidifier, while the AirSense 11 AutoSet runs about $1,050 to $1,100 for a similar setup. The difference
