The ClimateLineAir 11 — warm air, and no water in the tube
Heated tubing for the AirSense 11 and AirCurve 11. It keeps the air warm on the way to your mask and unlocks Climate Control on your machine, which is what stops the condensation that pools in a standard tube overnight.
Genuine original equipment · part 39102 · no prescription needed for tubing · free U.S. shipping over $99.
Why heated tubing
Rainout is the water that condenses inside a cold tube and eventually arrives at your face. Heating the tube keeps the air above the dew point, so the moisture stays where it belongs — as humidity, not as droplets.
Plug it in and your machine gains Climate Control: it manages tube temperature and humidity together, automatically, instead of you guessing at a humidifier setting every night.
Thinner and lighter than standard tubing, so it drags less when you turn over — which matters more than it sounds, because hose drag is what pulls masks off their seal.
⚠ Check this before you order
The most common mistake with this part.
This tubing is not universal. The ClimateLineAir 11 is made for Air11 machines. If your machine is an AirSense 10 or AirCurve 10, you need the ClimateLineAir 10 — a different part that will not work here. Look at the model name printed on your machine, and if you’re not sure, call us before you order.
Who notices the difference most
If any of these sound like your nights, this is the fix.
Cold bedrooms make it worse: the colder the room, the sooner the humidified air hits its dew point inside the tube. If you sleep with the air conditioning on — which in Florida is most of the year — heated tubing is usually the single upgrade that makes therapy comfortable.
Details
What’s included
- ClimateLineAir 11 heated tube (part 39102)
Replacement tubing only. The machine, the humidifier tub and the mask are not included — this is the tube on its own.
Genuine original equipment — and no prescription needed
This is a genuine original-equipment tube, not a compatible copy. Tubing, masks, cushions and filters don’t require a prescription in the U.S. — only the CPAP or BiPAP machine does. On a heated tube the electronics matter: a copy that doesn’t talk to your machine properly won’t give you Climate Control at all.
