Frequently asked questions

How do I adjust the comfort features – humidity and ramp time – on my AirSense 11?
How to access your comfort settings on the AirSense 11:

On your AirSense 11 machine, use the touchscreen to go to My Options to see your current settings. From here, you can personalize your options.

Humidity Level
The humidifier moistens the air and is designed to make your therapy more comfortable. With the Climate Control Auto setting, both temperature and humidity are automatically preset at levels designed for maximum comfort. If you have a ClimateLineAir™ heated tube, all you have to do is plug it in and press Start. Note: ClimateLineAir heated tubing is required to use Climate Control Auto.

You can also manually set the Humidity Level to Off or between 1 and 8, where 1 is the lowest humidity setting and 8 is the highest humidity setting.

If you’re getting a dry nose or mouth, turn up the humidity. If you’re getting any moisture in your mask, turn down the humidity.

How to adjust humidity:
In My Options, select Humidity Level. Scroll and select the desired humidity level.

Ramp Time
Ramp Time is the period during which the pressure increases from a low start airflow pressure to your prescribed treatment pressure. You can set your Ramp Time to Off, from 5 to 45 minutes or Auto. When Ramp Time is set to Auto, the device will detect when you have fallen asleep and then gradually increase to the prescribed treatment pressure.

How to adjust Ramp Time:
In My Options, select Ramp Time and adjust to your preferred setting.

How do I get an AirSense 11, how much does it cost and is it covered by insurance?
A CPAP prescription is required for an AirSense 11. Cost and coverage vary by insurance provider and plan. Once your doctor has provided you with a prescription, contact your insurance provider to learn more about what’s covered under your plan. Then you can find a CPAP equipment store near you or shop online.

How to clean your CPAP machine

Time it takes: 5 minutes

Supplies you’ll need to clean your machine:

Sink or tub
Warm, drinking-quality water (86°F / 30°C)
Mild soap
Clean towel
Weekly step-by-step cleaning tips:

Unplug the machine. Wash the water tub and air tubing in warm water using mild detergent. Do not wash in a dishwasher or washing machine.
Rinse the water tub and air tubing thoroughly and allow to dry out of direct sunlight and/or heat.
Wipe the exterior of the device with a dry cloth or towel.
Can I use an ozone device to clean my ResMed machine?
ResMed has observed that prolonged and repeated use of an ozone device may eventually cause internal damage to a ResMed machine, leading to an increase in motor noise. The ResMed limited warranty excludes damage to ResMed machines caused by use of ozone devices.
How often should I replace my CPAP machine parts and can I sign up for a replacement program?
It’s important to regularly inspect, clean and replace your CPAP supplies, which can be affected by dirt and general wear. You should regularly check the water tub, air tubing and air filter for any signs of wear or damage.

Here are some replacement tips for your CPAP parts:

Water tub:
Replace if it begins leaking or has become cracked, cloudy or pitted.
Replace if the seal is cracked or torn.
Remove any white powder deposits using a solution of one part household vinegar to 10 parts water.
Air tubing:
Replace if there are any holes, tears or cracks.
Air filter:
CPAP air filters can wear out or become clogged over time, potentially exposing you to airborne particles, mold and bacteria. We recommend checking them twice per month.
For help with when and how to replace your machine parts, contact your CPAP equipment store and ask if they have a replacement supply (resupply) program so you can get new parts on a consistent schedule. You should also check with your insurance provider to see what replacement parts are covered under your plan and how often you can replace them.
