Frequently asked questions

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

Contact your CPAP equipment provider—the store where you obtained your CPAP mask and machine—for ongoing clinical support. They can help with questions, resolve mask comfort or fitting issues, and explore different mask options that may better meet your personal comfort needs. Adjusting to a mask can be challenging, so don’t hesitate to seek assistance Not sure who your CPAP equipment provider is? We can help, fill out our Contact Us form or simply use our Chat Bot.

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

You should clean the cushion, elbow and short tube, and vent ring daily. The headgear and frame only require weekly cleaning. 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.

HOW TO CLEAN YOUR MASK

Supplies you’ll need to clean your mask:

Sink or tub
Warm, drinking-quality water (86°F / 30°C)
Mild liquid detergent
Towel
Step-by-step cleaning tips:

1. Unplug your CPAP machine from the power source and disconnect your mask/tubing from your machine.
2. Disassemble your mask:
- Undo the fastening tabs on the upper headgear straps and pull from the frame.
Tip: Keep the magnetic clips attached to the lower headgear straps to easily distinguish the upper and lower straps when reassembling.
- Squeeze the side buttons on the elbow and detach from the vent ring.
- Pull the cushion stud out of the frame stud hole, and repeat on the other side.
- Pull the vent ring from the cushion.
3. Soak the components in warm water with a mild liquid detergent. Ensure that there are no air bubbles while soaking.
4. Shake the components vigorously in the water and hand wash with a soft bristle brush. Pay particular attention to the vent holes in the vent ring.
5. Thoroughly rinse the components under running water.
6. Squeeze the fabric components to remove excess water.
7. Leave the components on the towel to air dry out of direct sunlight.

Refer to the product user guide for complete instructions.

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

Ozone or UV light products have not been authorized for mask cleaning. These products may cause discoloration or damage that is not covered under the ResMed limited warranty. Warranty coverage for mask issues is applicable only if they are observed upon initial unpackaging.

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

Regular maintenance of your CPAP equipment, including your mask, is critical to prevent discomfort and skin irritation from accumulated dirt and oil. Simplify your routine by inquiring with your CPAP equipment store about enrolling in a replacement supply program for timely access to new supplies.

Why is the AirFit F40 mask cushion made from silicone material?

Silicone is used in CPAP mask cushions because it's hypoallergenic, soft, lightweight, and provides a secure, comfortable seal during sleep. Your comfort and therapy adherence should influence your choice of mask cushion. If you have skin sensitivity or discomfort, reach out to your CPAP equipment store for support.
