ResMed AirFit N20 Classic: MED

The ResMed AirFit N20 and ResMed AirFit N20 Classic are very similar nasal masks, but differ mainly in design and fit.

The standard AirFit N20 has a modern, minimal design without forehead support, using magnetic clips for quick on/off and a lighter feel. In contrast, the N20 Classic features a traditional design with a forehead support frame and Velcro tabs, offering added stability for those who prefer a more secure fit.

Both masks use the same InfinitySeal cushion, so performance and seal quality are comparable.

In short, the choice comes down to preference: lighter and simpler (N20) vs more structured and supportive (N20 Classic).

The ResMed AirFit and ResMed AirTouch are similar mask ranges, but the key difference is the cushion material.

AirFit masks use silicone cushions, which are durable, easy to clean, and provide a reliable, secure seal - especially if you move during sleep. In contrast, AirTouch masks use memory foam (or soft fabric) cushions, designed to mould to your face for a softer, more personalised feel.

Because of this, AirFit cushions typically last longer and can be washed, while AirTouch cushions need more frequent replacement and gentler care.

The ResMed AirFit N20 Classic Nasal Mask is best suited for specific types of CPAP users:

Nasal breathers – as a nasal mask, it’s designed for people who primarily breathe through their nose during sleep.

Users who can’t use magnetic masks – it uses Velcro tabs and hooks instead of magnets, making it suitable for those with medical implants or preferences against magnets.

Active sleepers – the forehead support and stable frame help maintain a seal, even if you toss and turn throughout the night.

Overall, it’s ideal for those wanting a secure, dependable fit with a more traditional design.

Yes, the ResMed AirFit N20 Classic is designed to work with almost all CPAP, APAP and BiPAP machines that use tubing with a standard 22 mm cuff, making it a highly versatile option. Whether you’re using a ResMed device, a different brand, or upgrading your setup, it connects easily without the need for adapters.

It’s fully compatible with popular ResMed machines like the AirSense 10 and AirSense 11, and also works with ClimateLineAir heated tubing for added comfort and consistent therapy overnight.

This broad compatibility makes switching to the AirFit N20 Classic Nasal Mask simple, whether you’re new to CPAP or replacing an existing mask, offering convenience across nearly any setup.

The ResMed AirFit N20 Classic Nasal Mask is available with Small, Medium, or Large cushions. To fit the mask, place the cushion over your nose, bring the headgear over your head, and attach the clips. Start with light tension, as the InfinitySeal™ cushion works best when it is not overtightened, allowing for a comfortable and secure seal.

If you require more mouth coverage or use higher therapy pressures, a full-face mask such as the ResMed AirFit F20 may be more suitable.

Cleaning & Maintenance
Keeping your CPAP mask clean is key to maintaining performance, comfort, and hygiene, while also helping extend its lifespan.

Daily Cleaning
After each use, wipe the nasal cushion with a damp cloth or CPAP-safe wipe to remove oils and residue. Alternatively, wash gently with warm water and mild soap, then air dry away from direct sunlight.

Weekly Cleaning
Once a week, disassemble the mask (cushion, frame, and headgear) and wash all parts in warm water with mild detergent. Rinse thoroughly and allow to air dry completely out of direct sunlight.

Additional Tips

Avoid harsh cleaners, bleach, or alcohol-based wipes, as they can damage components.

Regularly check for signs of wear and replace parts as needed.

Following these steps helps ensure your AirFit N20 Classic remains comfortable, hygienic, and effective night after night.

Regularly replacing your CPAP mask and its components is essential for maintaining effective therapy, ensuring a secure seal, and keeping your equipment hygienic. Over time, cushions, headgear, and other parts can wear down, lose elasticity, or become discoloured, which can affect comfort and therapy performance.

Replacement guidelines for the AirFit N20:

Nasal cushion: Replace every ~6 months, or sooner if the seal begins to deteriorate or the cushions feel stiff or cracked.

Headgear: Replace approximately every 6 months, or sooner if it stretches, frays, or loses its ability to hold the mask securely.

Frame and short tube: Inspect regularly and replace as needed if you notice cracks, warping, or discolouration.

Entire mask: It’s recommended to replace the complete mask approximately every 12 months to ensure optimal hygiene, comfort, and performance.

Regular inspection and timely replacement of each component help maintain a comfortable fit, a secure seal, and effective CPAP therapy night after night. Keeping a replacement schedule also reduces the risk of leaks, irritation, or other issues that can affect sleep quality.

Yes, the AirFit N20 Classic is generally suitable for side sleepers. Its adaptive frame and forehead support help maintain a stable fit, while the cushion is designed to flex with movement and maintain a seal as you change positions throughout the night. This makes it a reliable option for those who sleep on their side, although overall comfort will still depend on factors like proper fit, strap adjustment, and pillow choice.

Yes, the AirFit N20 Classic Nasal CPAP mask is safe for use with magnetic implants, as it contains no magnetic components. Always consult your doctor if you are uncertain about your suitability for specific masks.

If you notice redness, pressure marks, or skin irritation from the AirFit N20 Classic nasal CPAP mask, start by loosening the headgear slightly to reduce pressure on your nasal bridge and surrounding areas. The InfinitySeal™ cushion works best when the mask is not overtightened, so a gentle adjustment can often improve comfort. Cleansing your face before bed can also help, as oils, sweat, and residue on the skin can contribute to irritation. If discomfort persists, consider trying a different cushion size, as switching to a small, medium, or large cushion can improve the fit and reduce pressure points.

Users with sensitive skin may prefer the AirTouch N20 cushion, which features UltraSoft™ memory foam that provides a plush and gentle alternative to the standard silicone cushion. In some cases, irritation may be related to mouth leaks or nasal congestion. Users who frequently breathe through their mouth or experience persistent congestion might find a full-face mask, such as the ResMed AirFit F20, provides better coverage and helps maintain effective therapy. By adjusting the fit, selecting the appropriate cushion, and addressing any breathing or congestion issues, most users can achieve a comfortable and effective CPAP experience with the AirFit N20 Classic nasal mask.

The Resmed AirFit P10 For Her CPAP Mask is compatible with all standard CPAP tubing. Before fitting, make sure that the swivel piece from your previous mask is still not in the tubing, as this can prevent the new mask from connecting properly. Removing the swivel piece may require some strength and a firm pull. If you are still unable to attach the mask, please call 1300 76 29 39 for assistance from one of our friendly CPAP consultants.
