The ResMed AirFit N20 is a compact nasal CPAP mask with an InfinitySeal cushion designed to fit 99% of faces, delivering a dependable seal at just 24 dB with a clear, open line of sight.
The AirFit N20 is ResMed’s most popular nasal mask, and the 794+ reviews and 88% recommendation rate tell you why. Its InfinitySeal silicone cushion uses specially designed loops and varying thickness levels to adapt to virtually any face shape, maintaining a reliable seal across pressures from 4 to 30 cmH₂O, whether you’re on your back or rolling onto your side.
The flexible frame sits below the eyes with no forehead support, giving you an unobstructed field of vision for reading, watching TV, or wearing glasses before bed. A short tube with triple-swivel connection lets active sleepers turn without hose drag, and QuietAir venting keeps noise down to just 24 dB. Magnetic clips snap the headgear on in seconds, and the quick-release elbow lets you disconnect for a bathroom trip without removing the mask. Available in Standard and “For Her” headgear options, and compatible with the AirTouch N20 memory foam cushion if you prefer a softer feel.
Universal Fit (InfinitySeal Cushion): Specially designed loops and varying silicone thickness adapt to 99% of face shapes, maintaining a stable seal at any pressure from 4–30 cmH₂O.
Ultra-Secure Seal: The InfinitySeal holds steady across all sleeping positions. Toss and turn without worrying about leaks breaking your therapy.
QuietAir Vents (24 dB): Muffled exhalation port operates quieter than a whisper, keeping both you and your bed partner undisturbed.
Open Line of Sight: No forehead support means an unobstructed view. Wear glasses, read a book, or watch TV without removing your mask.
Magnetic Clips + Quick-Release Elbow: Self-guiding magnets snap headgear on in seconds. The quick-release elbow disconnects from tubing without removing the mask, so bathroom trips don’t undo your fit.
Plush Padded Headgear: Soft, padded straps minimize pressure points and red marks. Four adjustment tabs let you dial in a custom fit that holds night after night.
Short Tube + Triple-Swivel: Reduces hose drag and lets active sleepers turn freely without tugging the mask off-seal.
Choosing the Right Size: Standard headgear fits most adults. If you have smaller facial features, select the “For Her” option. Large headgear is available separately.
Replacement Schedule:
Daily: Wipe cushion clean or wash with mild soap and water. Rinse elbow and short tube. Air dry out of direct sunlight.
Weekly: Disassemble completely. Wash all parts in warm water with mild soap. Brush inside the short tube. Rinse thoroughly and air dry.
Specifications:
ResMed’s InfinitySeal cushion adapts to virtually any face shape and holds a steady seal at any pressure. No constant readjusting, no middle-of-the-night leak battles. Just put it on and sleep.
QuietAir venting diffuses exhaled air so softly that it registers below a whisper. Light sleepers and bed partners both benefit from a calmer, quieter bedroom.
Self-guiding magnets snap the headgear into place. The quick-release elbow lets you disconnect for water or a bathroom trip without undoing a single strap. Your fit stays locked in all night.
Push the side buttons on the frame and pull the elbow away. Unclip the magnets, undo the upper headgear tabs, pull the strapping away, then hold the frame between the upper and lower arms and pull the cushion off.
Every 3–6 months, or immediately if you notice visible wear, damage, or a decline in seal quality.
Yes. The AirFit N20 and AirTouch N20 share the same frame and headgear. You can swap between the silicone InfinitySeal and the AirTouch memory foam cushion anytime.
The N30 is the newer generation and is quieter (18 dB vs. 24 dB). Both are lightweight nasal masks, but if you’re a very light sleeper, the N30’s lower noise level may be worth the upgrade.
The “For Her” option features smaller-proportioned headgear designed for users with petite facial features. The mask frame and cushion are the same.
Yes, with the N20 AirMini Setup Pack (sold separately), which includes the custom connector, proprietary tubing, and HumidX humidification cartridges.
Yes. The short tube with triple-swivel and low-profile frame make it comfortable for side sleeping. It stays sealed during position changes without catching on your pillow.
24 dB, which is quieter than a whisper. The QuietAir venting muffles exhaled airflow so it won’t disturb you or your partner.
The N20 covers the nose only. If you tend to breathe through your mouth during sleep, pair it with a chin strap to keep your mouth closed, or consider a full face mask like the AirFit F20 or F30i.
It’s rated for 4–30 cmH₂O, covering the full range of CPAP and BiLevel therapy pressures.
