ResMed N20 Nasal Mask | AirFit N20 CPAP Mask for Sleep Apnea Therapy

Unlike full-face masks that cover your nose and mouth, the ResMed AirFit N20 covers only the nose — which means a lighter feel, less material on your face, and an open field of vision if you like to read or watch TV before falling asleep. It works with both CPAP and BiPAP machines, and is a good fit for anyone who breathes primarily through their nose during sleep. If you’re new to sleep apnea therapy, this is a good starting point to understand what nasal masks are designed to do.

The ResMed AirFit N20 Is Built for Patients Who Need:

• ✓A secure seal that holds even when you change sleeping positions
• ✓A lighter alternative to full-face masks without giving up seal reliability
• ✓An open field of vision for reading, using a phone, or watching TV before sleep
• ✓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

Who Should Use the ResMed AirFit N20

• ✓Patients who breathe primarily through the nose during sleep
• ✓Active or side sleepers who need a seal that holds through position changes
• ✓Anyone who finds full-face masks too bulky or claustrophobic
• ✓New CPAP users looking for an easy-to-fit, easy-to-clean starter mask
• ✓Both CPAP and BiPAP users under a doctor’s prescribed therapy plan for the ResMed AirFit N20

The ResMed AirFit N20 is a nasal CPAP mask used to deliver positive airway pressure therapy for obstructive sleep apnea. It connects to your CPAP or BiPAP machine and covers only the nose, making it a lighter alternative to full-face masks for patients who breathe through their nose during sleep.

The AirFit N20 comes in Small, Medium, and Large. ResMed recommends measuring the width of your nose (outer edge to outer edge) with a ruler or fitting template. If you’re between two sizes, ResMed generally recommends sizing up for comfort. Your CPAP provider can also help you fit the mask correctly.

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.

Yes, the AirFit N20 is designed to work with standard CPAP, APAP, and BiPAP machines using a standard tube connection. If you’re using a specific travel device like the ResMed AirMini, you may need an additional setup pack or connector — check with your provider if you’re unsure.

The cushion, elbow, and short tube should ideally be cleaned daily, while the headgear and frame need only weekly cleaning with mild detergent and warm water. Regular replacement of cushions and headgear is recommended over time, since worn parts can affect seal quality — ask your CPAP provider about a resupply schedule.

Yes — this is one of the more common reasons patients choose the N20. The InfinitySeal cushion is designed to adapt as you change positions during the night, which helps it hold its seal better than more rigid cushion designs when you’re sleeping on your side.

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.
