ResMed AirFit F20 Full Face Mask

Unlike traditional full face masks that rely on forehead support, the AirFit F20 uses a low-profile, open-view frame that sits below the eyes — keeping your line of sight clear for reading or watching TV before you fall asleep. It works with CPAP, APAP, and BiPAP machines, making it a versatile option whether you breathe through your nose, your mouth, or both.

• ✓ Full nose-and-mouth coverage for mouth breathers or nasal congestion
• ✓ A secure seal that holds through higher therapy pressures
• ✓ An open field of vision without bulky forehead support
• ✓ A mask that’s quick to put on and take off during nighttime bathroom breaks
• ✓ Long-term daily use with easy cleaning and part replacement

• ✓ Patients who breathe through their mouth during sleep, or have nasal congestion
• ✓ Active or side sleepers who need a seal that holds through position changes
• ✓ Patients on higher CPAP/BiPAP pressure settings who need a dependable seal
• ✓ Anyone who finds older full face masks too bulky or claustrophobic
• ✓ Both CPAP and BiPAP users under a doctor’s prescribed therapy plan

What is the ResMed AirFit F20 used for?

The ResMed AirFit F20 is a full face CPAP mask used to deliver positive airway pressure therapy for obstructive sleep apnea. It covers both the nose and mouth, making it a good choice for mouth breathers or patients with nasal congestion who can’t rely on a nasal-only mask.

How do I know which size to order?

The AirFit F20 is available in Small, Medium, and Large. ResMed recommends measuring from the bridge of your nose to the indent of your chin with a ruler or the fitting template included in the box. If you’re between sizes, sizing up is generally recommended for comfort.

Are there any safety precautions with the magnetic clips?

Yes. This mask uses magnetic clips for quick attachment, and ResMed advises keeping these magnets away from certain implanted medical devices or metallic implants that could be affected by magnetic fields. If you or anyone in close contact with you has such a device or implant, check with your doctor before use and refer to ResMed’s official labelling for full contraindication details.

Is this mask compatible with my CPAP or BiPAP machine?

Yes, the AirFit F20 is designed to work with standard CPAP, APAP, and BiPAP machines using a standard tube connection. If you’re using a travel device like the ResMed AirMini, you may need an additional setup pack — check with your provider if you’re unsure.

How often should I clean it, and how often should parts be replaced?

Clean the cushion, frame, and elbow daily with mild soap and warm water, then rinse and air dry. Regular replacement of the cushion and headgear is recommended over time, since worn silicone can affect seal quality — ask your CPAP provider about a resupply schedule.

Can I use this mask if I have facial hair?

You can, though facial hair may affect the seal depending on its style and thickness. The adaptive InfinitySeal cushion is designed to accommodate a range of facial contours, but a well-trimmed area around the seal line generally helps maintain a better fit.

What’s covered under the warranty?

ResMed’s mask systems, including the frame, cushion, headgear, and elbow, are covered by a 90-day manufacturer warranty against defects in material and workmanship from the date of purchase. This doesn’t cover normal wear and tear, damage from misuse, or damage from smoke or ozone exposure.
