ResMed AirSense 10: The Complete UK Guide
ResMed AirSense 10: The Complete UK Guide
Full specifications, setup, maintenance, troubleshooting, and the honest answer to whether you should still buy one in 2026.
Shop the ResMed AirSense 10 AutoSetThe ResMed AirSense 10 is one of the most widely used CPAP platforms ever made, and it remains a capable, well-supported machine in 2026. This guide covers every feature, setting, accessory and maintenance task in plain English — plus the honest answer to whether you should still buy one.
If you have been prescribed CPAP therapy in the UK, the ResMed AirSense 10 is almost certainly a machine you will come across. It has been the default device in NHS sleep clinics and private practice for the best part of a decade, and there are more AirSense 10 units in bedrooms worldwide than any other CPAP platform.
But the AirSense 10 sits in an unusual position right now. It is simultaneously the most proven CPAP machine on the market and a device that ResMed has moved on from. That makes buying advice genuinely more complicated than "newer is better" — and it is why this guide covers not just what the machine does, but what its lifecycle status means for you as a UK buyer.
Key Takeaways
- Still an excellent machine. AutoSet algorithm, integrated humidification, EPR and AutoRamp cover everything the vast majority of CPAP users need.
- Production has ended. ResMed stopped manufacturing the AirSense 10 in 2023, though support and replacement parts continue.
- Connectivity varies significantly by variant. This is the single most misunderstood point about the AirSense 10 — check before you buy.
- UK buyers may be exempt from VAT. If you have been diagnosed with sleep apnoea, this is roughly a 20% saving.
- A prescription is required to purchase a CPAP machine in the UK.

Is the AirSense 10 Still Available in 2026?
Yes — but with an important caveat that most retailers do not mention.
ResMed ceased manufacturing the AirSense 10 in 2023. The machine is still listed, still sold through distributors and retailers, and ResMed continues to provide support and replacement parts for existing users. What you are buying today is remaining stock rather than current production.
This is not a reason to avoid the machine. CPAP devices have long service lives, the accessory ecosystem for the AirSense 10 is enormous, and consumables such as filters, cushions and water chambers remain widely available. But it does mean two things are worth thinking about before you commit.
What discontinuation actually means for you: Support and parts continue for now, but a device that is no longer manufactured will eventually reach the end of its supported life. If you are buying a machine you expect to use for the next seven to ten years, factor that into the decision — particularly if the price difference against a current-production model is small.
The AirSense 10 AutoSet for Her variant has been discontinued separately and is increasingly hard to source new.
The AirSense 10 Range Explained
"AirSense 10" is a family of machines rather than a single device, and the differences between them matter more than the shared name suggests. ResMed's own documentation describes the series as comprising two therapy models — CPAP and AutoSet — but the retail picture is more fragmented because of connectivity variants.
By therapy mode
AirSense 10 AutoSet
The auto-adjusting (APAP) model. Continuously adjusts pressure within a prescribed range in response to your breathing. This is the version most people mean when they say "AirSense 10", and the version most commonly prescribed.
AirSense 10 CPAP / Elite
Delivers one fixed prescribed pressure all night rather than adjusting. Prescribed where a titration study has established a specific effective pressure, or where a clinician prefers fixed-pressure therapy.
AirSense 10 AutoSet for Her
An AutoSet variant with an algorithm tuned to breathing patterns more common in women, including a stronger response to flow limitation. Now discontinued by ResMed.
AirSense 10 Card-to-Cloud
A connectivity variant rather than a therapy variant. Stores data on an SD card instead of transmitting it. Increasingly the most common version still available new.
Why the variant matters more than you'd think
This is the point that trips people up, and it is worth reading carefully before you buy.
ResMed's clinical documentation states that current AirSense 10 devices do not have built-in cellular connectivity, meaning no wireless data transmission and no compatibility with myAir, ResMed's therapy tracking app. Older AirSense 10 production runs did include cellular modems and full myAir support.
In practical terms: two machines both labelled "AirSense 10 AutoSet" can behave completely differently when it comes to data. One syncs your therapy data to your phone every morning. The other stores it on an SD card that you physically remove and hand to your clinician.
Before you buy, ask one question: does this specific unit have cellular connectivity and myAir support, or is it a Card-to-Cloud device? If nightly sleep scores on your phone matter to you, this single answer should drive your purchase. Any reputable UK retailer will tell you outright — if they cannot answer clearly, buy elsewhere.
How the AutoSet Algorithm Works
The AutoSet algorithm is the AirSense 10's headline feature and one of the most clinically published algorithms in sleep-disordered breathing.
Rather than delivering a single pressure all night, the machine monitors your breathing breath by breath and adjusts pressure within the range your clinician has set. When it detects the airway starting to narrow — through flow limitation, snoring or an apnoea — it raises pressure. When your breathing settles, it eases pressure back down.
The practical benefit is that you spend most of the night at a lower pressure than a fixed-pressure prescription would require, because fixed pressure has to be set high enough to cover your worst moments. Lower average pressure generally means better comfort, fewer leaks and better tolerance.
Advanced event detection
The AirSense 10 does not simply count apnoeas. It differentiates between obstructive and central events, and can identify indications of Cheyne-Stokes respiration and respiratory effort related arousals (RERAs). This distinction matters clinically — central apnoeas do not respond to increased pressure the way obstructive ones do, and a machine that cannot tell them apart may raise pressure pointlessly.
AutoSet Response
ResMed later added an AutoSet Response setting, which offers the same algorithm with gentler pressure increases. If you find the standard AutoSet response too aggressive — a common complaint among new users who wake when pressure climbs — this is worth raising with your clinician.
Comfort Features in Detail
Comfort features are not luxuries in CPAP therapy. Non-adherence is the single biggest reason CPAP fails, and most people who abandon therapy do so within the first month because of discomfort. These features exist to keep you using the machine.
AutoRamp with sleep onset detection
Starts therapy at a low, comfortable pressure and holds it there until the machine detects you have fallen asleep, then climbs to your prescribed pressure. Unlike a plain timed ramp, it responds to you rather than a stopwatch.
EPR (Expiratory Pressure Relief)
Drops pressure slightly each time you breathe out, at levels 1 to 3. Breathing out against full pressure is the most common early complaint, and EPR addresses it directly.
SmartStart
Begins therapy as soon as you breathe into the mask and stops shortly after you take it off, so you never have to find the button in the dark.
Easy-Breathe motor
ResMed's quiet motor design, rated at around 25 dBA sound pressure. Quiet enough that most bed partners report the mask leak is louder than the machine.
Mask Fit check
Runs a short test and displays whether your mask seal is good before you settle down, rather than leaving you to discover a leak at 3am.
Ambient light sensor
Dims the display automatically in a dark room and turns it off entirely during therapy. A small thing that matters a lot if you sleep in a dark bedroom.
Humidification and Climate Control
The AirSense 10 has an integrated HumidAir heated humidifier — it is built into the machine, not a separate add-on. The water chamber holds roughly 380 ml, and humidity is adjustable from Off through levels 1 to 8.
Humidification exists because pressurised air moving through your nose and throat all night dries them out. Dry mouth, sore throat, nosebleeds, and morning congestion are among the most common reasons people give up on CPAP, and in most cases they are a humidity problem rather than a therapy problem.
Climate Control and how it works
When paired with a ClimateLineAir heated tube, the machine can run Climate Control Auto. Instead of you guessing at a humidity number, the system targets a consistent temperature and humidity at the mask, adjusting as your bedroom cools overnight. The tube itself can be set between 16°C and 30°C.
This is the main defence against rainout — condensation forming in the tube and dripping onto your face. If you have ever woken up to a gurgling hose or a wet cheek, a heated tube is the fix.
Practical tip: Use distilled or cooled boiled water in the chamber rather than tap water. In hard-water areas of the UK, tap water leaves limescale deposits that shorten the chamber's life and are difficult to remove.
Choosing the Right Tubing
The AirSense 10 works with three tube types, and the choice affects comfort more than most people expect.
| Tube | Diameter | Best for | Notes |
|---|---|---|---|
| ClimateLineAir | 15 mm | Rainout, cold bedrooms, dryness | Heated. Enables Climate Control Auto. The AirSense 10 version only. |
| SlimLine | 15 mm | Reducing drag on the mask | Lighter and more flexible than standard. Unheated. |
| Standard | 19 mm | General use, budget replacement | Heavier. Widely available and inexpensive. |
Critical compatibility warning: The AirSense 10 uses ClimateLineAir. The AirSense 11 uses ClimateLineAir 11. These have different machine-side connectors and are not interchangeable in either direction. If you are moving between generations, your heated tube does not come with you.
Need a replacement heated tube?
The ClimateLineAir for AirSense 10 is the correct heated tube for this machine — the AirSense 11 version will not fit.
Data, myAir and Connectivity
How the AirSense 10 handles your therapy data depends entirely on which variant you have, as covered above. There are three broad scenarios.
Cellular-equipped models
Older AirSense 10 units with a built-in cellular modem upload data automatically overnight. You wake up, open myAir, and see a sleep score out of 100 based on usage hours, mask seal, events per hour and how many times the mask came off. Your clinician sees the same data through ResMed AirView.
Card-to-Cloud models
These store data on an SD card. There is no automatic upload and no myAir. To share data, you remove the card and either post it to your provider or upload it through a compatible service. Many self-managing users actually prefer this, because the raw card data can be read in third-party analysis software in far more detail than myAir offers.
What the data actually tells you
- AHI (Apnoea-Hypopnoea Index) — events per hour. Under 5 is generally the target, but interpretation is your clinician's job.
- Usage hours — most compliance schemes look for 4+ hours per night on 70% of nights.
- Mask seal — high leak figures usually mean the wrong size or worn cushion, not a faulty mask.
- Pressure achieved — the 95th percentile pressure tells you what the machine actually needed.
Compatible Masks
The AirSense 10 uses a standard connection, so essentially any CPAP mask from any manufacturer will work with it. Mask choice comes down to how you breathe and how you sleep, not which machine you own.
Full face masks
Cover nose and mouth. Best if you breathe through your mouth at night, have chronic congestion, or need higher pressures. The most forgiving option for back sleepers.
Nasal masks
Cover the nose only. Less bulk than full face, good seal, and suit most people who breathe through their nose. A solid default choice.
Nasal pillow masks
Seal at the nostrils. The most minimal option — best for side sleepers, people who feel claustrophobic, and anyone who wears glasses in bed or reads before sleep.
Fitpacks
Include multiple cushion sizes in one box. Genuinely worth it for a first mask, because cushion sizing is the most common reason a mask leaks.
Not sure which mask suits you?
Mask fit matters more to therapy success than the machine itself. Our mask finder narrows it down by breathing type and sleep position.
Setup and Your First Week
Cleaning and Maintenance Schedule
Regular cleaning is not just hygiene — a dirty filter or a degraded cushion directly reduces therapy effectiveness.
| Task | How often | How |
|---|---|---|
| Wipe mask cushion | Daily | Warm water and mild soap, air dry out of direct sunlight |
| Empty water chamber | Daily | Discard leftover water, rinse, refill fresh each night |
| Wash mask and headgear | Weekly | Mild soap, rinse thoroughly, air dry |
| Wash tubing | Weekly | Warm soapy water, hang to dry |
| Wash water chamber | Weekly | Mild soap, rinse well, check for cracks and cloudiness |
| Check air filter | Monthly | Replace if visibly dirty or discoloured |
| Replace air filter | Every 6 months | More often in dusty homes or with pets |
| Replace mask cushion | Every 1–3 months | Sooner if it feels sticky, discoloured or stops sealing |
| Replace tubing | Every 3–6 months | Check for cracks, holes and cloudiness |
| Replace headgear | Every 6 months | Replace when it stretches and stops holding tension |
| Replace water chamber | Every 6–12 months | Sooner if scaled, pitted or cloudy |
Do not use these: bleach, chlorine, alcohol-based cleaners, scented or antibacterial soaps, dishwashers, or washing machines. They degrade silicone and plastics and can leave residues you will then breathe in all night.
Keep your therapy working properly
Filters, cushions, chambers and headgear are the parts that quietly degrade and take therapy quality with them.
Troubleshooting Common Problems
| Problem | Likely cause | What to try |
|---|---|---|
| Water in the tube (rainout) | Warm humid air cooling in a cold bedroom | Use a ClimateLineAir heated tube, lower humidity a level, or route the tube under the duvet |
| Dry mouth or throat | Humidity too low, or mouth leak with a nasal mask | Raise humidity a level. If using a nasal mask, consider a chin strap or full face mask |
| Mask leaks | Wrong cushion size or worn cushion — usually not overtightening | Run Mask Fit, check cushion size, replace if over 3 months old |
| Pressure feels too strong | Not yet acclimatised, or ramp not enabled | Enable AutoRamp, ask your clinician about EPR or AutoSet Response |
| Machine louder than usual | Blocked or dirty filter, or an unseated chamber | Check and replace the filter, reseat the water chamber |
| Red or sore nose bridge | Headgear too tight, or wrong mask style | Loosen slightly and re-run Mask Fit. Consider a nasal pillow or under-nose mask |
| Bloating or swallowing air | Aerophagia — pressure entering the stomach | Speak to your clinician. Do not adjust prescribed pressure yourself |
| Waking with the mask off | Subconscious removal, common in early weeks | Usually resolves with acclimatisation. Check comfort settings and mask fit |
Travel and Flying with the AirSense 10
The AirSense 10 meets FAA requirements for all phases of air travel, and the same standard is accepted by UK and European carriers.
- Carry it as hand luggage. Medical devices do not count towards your cabin baggage allowance with most airlines, but confirm with yours in advance.
- Empty the water chamber before you fly — liquid restrictions apply, and a full chamber can spill in transit.
- Use aeroplane mode on cellular-equipped models before boarding.
- Altitude is handled automatically up to 2,591 m (8,500 ft). Above that, therapy may be affected.
- The power supply is multi-voltage, so overseas you need a plug adaptor rather than a voltage converter — but check your specific supply's label.
- Carry a travel letter from your clinician or the ResMed compliance letter for security queries.
If you travel frequently, a dedicated travel machine may serve you better than carrying the AirSense 10 — see our range of travel CPAP machines, and our guide to CPAP batteries for travel, camping and power cuts.
AirSense 10 vs AirSense 11
Both machines share the therapy fundamentals — AutoSet, AutoRamp, EPR and integrated humidification. The AirSense 11 adds a touchscreen, Personal Therapy Assistant, Care Check-In, Bluetooth, over-the-air software updates and a slightly smaller footprint.
The honest summary: if your AirSense 10 works reliably and your therapy is effective, there is no medical reason to upgrade. If you are buying new today, the AirSense 11 is the more future-facing platform simply because it is still in production.

Buying an AirSense 10 in the UK
You need a prescription
CPAP machines are prescription medical devices in the UK. You will need a diagnosis of obstructive sleep apnoea and a prescription specifying your therapy settings. If you have not yet been diagnosed, a home sleep test is usually the first step.
VAT relief — worth roughly 20%
This is the point UK buyers most often miss. If you have been diagnosed with sleep apnoea, you may be eligible to purchase CPAP equipment without VAT under the relevant HMRC provisions for chronic medical conditions. On a machine costing several hundred pounds, that is a substantial saving.
Eligibility is claimed by completing a short declaration at checkout — you do not need to send documentation in advance. Full details are on our VAT relief page.
Check before you compare prices: Some retailers display prices including VAT and some exclude it. When comparing two quotes, make sure you are comparing like for like — a headline price that looks 20% higher may actually be identical once relief is applied.
Warranty and what to check
- Confirm the exact model and connectivity variant in writing before ordering
- Check the warranty period and whether it is handled in the UK or requires shipping abroad
- Confirm whether the humidifier, tubing and mask are included or sold separately
- For pre-owned units, ask for the recorded running hours
- Check that the seller can supply consumables for the machine long term

Everything else people ask us.
Is the ResMed AirSense 10 still a good machine in 2026?
Yes. The therapy features — AutoSet, AutoRamp, EPR and integrated humidification — cover what the vast majority of CPAP users need, and the algorithm has an extensive clinical track record. The main considerations are that it is no longer manufactured and that connectivity varies by variant.
Has the ResMed AirSense 10 been discontinued?
ResMed stopped producing the AirSense 10 in 2023. It is still sold through retailers from remaining stock, and ResMed continues to provide support and replacement parts for existing users.
Does the AirSense 10 work with myAir?
It depends on the variant. Older cellular-equipped units support myAir. ResMed's documentation states that current AirSense 10 devices do not have built-in cellular connectivity, meaning no wireless data transmission and no myAir compatibility. Always confirm the specific unit's connectivity before purchase.
What is the pressure range of the AirSense 10?
4 to 20 cm H₂O, adjustable in 0.2 cm increments. Your prescribed range is set by your clinician.
How loud is the ResMed AirSense 10?
ResMed lists a sound pressure level of 25 dBA with an uncertainty of 2 dBA, measured with SlimLine or Standard tubing to ISO 80601-2-70:2015. In practice most users find mask leak noise more noticeable than the machine itself.
Do I need a prescription to buy a CPAP machine in the UK?
Yes. CPAP machines are prescription medical devices. You will need a diagnosis of obstructive sleep apnoea and a prescription specifying your therapy settings.
Can I claim VAT relief on a CPAP machine?
If you have been diagnosed with sleep apnoea, you may be eligible to purchase CPAP equipment VAT-free under HMRC provisions for chronic medical conditions. Eligibility is claimed by completing a declaration at checkout.
Can I use my AirSense 10 heated tube with an AirSense 11?
No. The AirSense 10 uses ClimateLineAir and the AirSense 11 uses ClimateLineAir 11. The machine-side connectors are different and the tubes are not interchangeable in either direction.
Which masks work with the AirSense 10?
Effectively any CPAP mask, from any manufacturer, using a standard connection. Mask choice should be based on how you breathe and how you sleep rather than which machine you own.
How often should I replace the air filter?
Check it monthly and replace it at least every six months — more often if you have pets, live somewhere dusty, or the filter looks discoloured before then.
What water should I use in the humidifier?
Distilled water, or cooled boiled water. Tap water leaves limescale deposits, particularly in hard-water areas, which shorten the chamber's life.
Can I take the AirSense 10 on a plane?
Yes. It meets FAA requirements for all phases of air travel. Carry it as hand luggage, empty the water chamber before flying, and enable aeroplane mode on cellular-equipped units.
Can I change my own pressure settings?
No. Therapy pressure is prescribed by your clinician based on your diagnostic results. If your therapy feels uncomfortable or ineffective, speak to your healthcare provider rather than adjusting settings yourself.
