Frequently asked questions

I'm having issues with my CPAP mask and need help. Who should I contact?

The CPAP equipment provider – the store where you picked up your CPAP mask and machine – is responsible for providing you with ongoing clinical support, including answering any questions and helping you resolve any mask comfort or fitting issues that you may be experiencing. Getting used to a mask can be challenging and there may be a different mask option that will work better for your personal comfort needs, so don't hesitate to reach out!

How do I clean my mask and how often should I clean it?

You should clean your mask daily. Facial oil and dirt can easily build up on your mask parts when they’re not cleaned properly, which can lead to skin irritation. The good news? Cleaning your mask doesn’t take long, so working it into your morning routine should be a breeze.


Time it takes: 5 minutes

Supplies you'll need to clean your mask:

  1. Sink or tub
  2. Warm, drinking-quality water (86°F / 30°C)
  3. Dish soap (if possible, mild antibacterial)
  4. Towel

Daily step-by-step cleaning tips:

  1. Unplug your CPAP machine from the power source.
  2. Disconnect your mask and tubing parts from your machine.
  3. Disassemble your mask into three parts: headgear, cushion and frame.
  4. In the sink, clean your mask cushion and headgear to remove any oils. Gently rub with warm, drinking-quality water and mild soap.
  5. Avoid harsh cleaning products, including dish detergents, which may damage the mask or leave harmful residue.
  6. Rinse again thoroughly with warm, drinking-quality water.
  7. Place the cushion and frame on a towel and allow the parts to dry away from direct sunlight on a flat surface.

Can I use an ozone device to clean my ResMed mask?

Use of ozone may discolor a ResMed mask during the ResMed limited warranty period and that will not be covered. Discoloration of ResMed masks is only covered during the limited warranty period if it occurs upon initial unpackaging.

How often should I replace mask parts and can I sign up for a replacement program?

It's important to take regular care of your CPAP equipment – especially the various parts of your mask, which can be affected by dirt, oil and residue from your skin. Poorly cleaned CPAP masks can cause discomfort and skin irritation. The last thing we all need is another to-do item, so contact your CPAP equipment store and ask if they have a replacement supply (resupply) program that you can enroll in to get new parts on a consistent schedule.

Why is the AirFit F20 mask cushion made from silicone material?

Most CPAP masks have silicone cushions because it's a hypoallergenic material that's soft, lightweight and allows for a stable, comfortable seal on your face while you're sleeping. It's important that you decide what's most comfortable for you and your therapy when it comes to your mask cushion. If you experience skin irritation or are uncomfortable with your current mask, contact your CPAP equipment store to let them know so you can try a different mask. ResMed AirTouch F20 is an alternative that is the same mask as AirFit F20, only the cushion is made of our patented UltraSoft memory foam instead of silicone.

What is AirFit F20 for Her?

AirFit F20 for Her is the same mask as an AirFit F20 except it has lavender accents rather than the standard blue, and comes in sizes Small and Medium. Regular AirFit F20 is available in Small, Medium and Large.
