ResMed AirFit N20 Cushion Medium:
Choosing the right CPAP mask cushion can make a noticeable difference in your nightly sleep therapy. If you use a ResMed AirFit N20 nasal mask, the resmed airfit n20 cushion medium may be the replacement part you need to maintain a comfortable fit and a reliable seal.
The cushion is the soft part of the mask that rests against your nose. Over time, regular use can cause it to lose its original feel, collect oils, or become worn. Replacing a damaged or worn cushion can help you maintain your usual CPAP routine without necessarily purchasing an entirely new mask.
At Alfa Healthcare Supply Inc., we understand that choosing medical equipment parts can sometimes feel confusing. This guide explains what the medium cushion does, how to check compatibility, how to care for it, and when replacement may be necessary.
What is the ResMed AirFit N20 Cushion Medium?
The resmed airfit n20 cushion medium is a replacement silicone cushion designed for the ResMed AirFit N20 nasal CPAP mask. It sits around the nose and creates the seal needed to direct airflow from the CPAP machine through the mask.
ResMed designed the AirFit N20 cushion with InfinitySeal technology. Its flexible silicone construction is intended to adapt to different facial contours and help maintain a secure seal during sleep.

The medium size is one of three standard cushion sizes available for the AirFit N20: small, medium, and large. The best option depends on your facial shape and the fit of your existing mask, rather than your general clothing size or body weight.
If your current medium cushion fits correctly, replacing it with the same size can be a practical starting point.
Key Features of the ResMed AirFit N20 Medium Cushion
Understanding the cushion’s features can help you decide whether it is the right replacement for your mask.
1. Soft Silicone Construction
The cushion is made from silicone, a flexible material designed to rest against the skin while maintaining contact around the nose.
A properly fitted cushion should feel secure without requiring you to tighten the headgear excessively. If you experience persistent discomfort, check the fit and follow the manufacturer’s adjustment instructions.
2. InfinitySeal Cushion Technology
The AirFit N20 uses InfinitySeal technology to help the cushion adapt to facial contours and maintain a seal during CPAP therapy.
A reliable seal is important because significant air leaks can affect comfort and interfere with effective therapy. However, no cushion can guarantee a perfect fit for every person.
3. Medium Size for a Suitable Fit
The medium size provides an option for users whose measurements and fitting experience indicate that this size is appropriate.
Do not choose medium simply because it is the most common size you see online. Use the official sizing guide or consult your equipment provider if you are unsure.
4. Replaceable Design
One practical advantage of the AirFit N20 system is that the cushion can be replaced separately from the mask frame.
If the frame and other components remain in good condition, replacing only the worn cushion may be more economical than purchasing a complete mask.
5. Designed for AirFit N20 Masks
The cushion is made for the AirFit N20 mask system. Before ordering, confirm that your existing mask is an AirFit N20 and that the replacement listing specifies the correct cushion type.
Is the ResMed AirFit N20 Cushion Medium Right for You?
The resmed airfit n20 cushion medium may be a suitable choice if you already use an AirFit N20 mask and your current medium cushion fits comfortably.
Consider these points before buying:
- Your current size: If your existing medium cushion fits well and seals properly, the same size may be appropriate for replacement.
- Your mask model: Check the model name before ordering. A cushion made for a different mask may not fit correctly.
- Your comfort: The cushion should sit comfortably around your nose without causing excessive pressure or persistent skin irritation.
- Your mask seal: Frequent air leaks may indicate that the cushion is worn, the headgear needs adjustment, or the mask size requires reassessment.
A cushion that is too small or too large can affect the seal and comfort. If you are changing sizes, use ResMed’s fitting template rather than guessing.
How to Tell When Your CPAP Cushion Needs Replacement
CPAP cushions experience regular contact with skin and repeated cleaning. With time, their condition may change.
Here are common signs that it may be time to replace your cushion.
Visible Wear or Damage
Look for tears, cracks, permanent deformation, or other visible damage. A damaged cushion may no longer create a dependable seal.
Frequent Air Leaks
If your mask starts leaking more often despite correct positioning and reasonable headgear adjustment, inspect the cushion. Also check the frame, tubing, and headgear, because the cushion is not the only possible cause of leaks.
Changes in Cushion Feel
A cushion that has become unusually stiff, sticky, misshapen, or difficult to position may need replacement.
Persistent Skin Discomfort
Redness or irritation can occur for several reasons, including excessive strap tension, moisture, skin sensitivity, or an unsuitable fit. Inspect the cushion and adjust the mask according to the manufacturer’s instructions.
If discomfort continues, seek advice from your healthcare professional or CPAP equipment provider.
How often should you replace it? Replacement schedules depend on the manufacturer’s instructions, the cushion’s condition, your cleaning routine, and any applicable insurance or supplier guidelines. Follow the instructions for your specific mask and replace damaged parts promptly.
How to Replace the ResMed AirFit N20 Cushion Medium
Replacing the cushion is generally straightforward. Always refer to the official instructions for your mask model.
Step 1: Remove the Mask
Turn off or disconnect your CPAP equipment as appropriate. Remove the mask from your face and place it on a clean surface.
Step 2: Remove the Old Cushion
Carefully detach the existing cushion from the mask frame according to the manufacturer’s instructions. Avoid pulling or twisting the frame unnecessarily.
Step 3: Inspect the Frame
Check the frame for cracks, damage, or residue. If another component is damaged, replacing the cushion alone may not solve the problem.
Step 4: Attach the New Cushion
Align the new medium cushion with the compatible frame and secure it as instructed. Make sure the cushion is seated evenly and securely.
Step 5: Check the Fit
Put on the mask and adjust the headgear according to the user guide. The cushion should sit comfortably around your nose.
Step 6: Check for Leaks
Reconnect your CPAP equipment and check the mask seal using your device’s normal fitting procedure. If air continues to leak, reposition the mask and check the cushion installation.
Do not overtighten the straps to compensate for a poor seal. If the problem continues, consult your equipment provider.
How to Clean and Care for Your Medium Cushion
Proper care can help keep your cushion clean and comfortable.
- Clean regularly: Follow the cleaning frequency and method specified in the AirFit N20 user guide.
- Use suitable products: Use mild soap and water as directed by the manufacturer.
- Avoid harsh chemicals: Solvents, strong cleaners, and unsuitable disinfectants may damage the cushion.
- Rinse thoroughly: Remove soap residue after cleaning.
- Air-dry completely: Allow the cushion to dry away from direct heat and sunlight.
- Inspect before use: Check for damage, residue, or changes in shape.
Avoid using products such as oily lotions immediately before wearing your mask if they affect the seal or are discouraged by the manufacturer’s instructions.
Regular cleaning is important, but cleaning does not restore a cushion that is already damaged or worn out.
ResMed AirFit N20 Cushion Medium vs. Other Sizes
Choosing the right size is more important than choosing the largest or smallest option.
| Feature | Small | Medium | Large |
| Intended use | Suitable for a smaller nasal fit | Suitable for a medium nasal fit | Suitable for a larger nasal fit |
| Compatibility | AirFit N20 system | AirFit N20 system | AirFit N20 system |
| Replacement | Available separately | Available separately | Available separately |
These descriptions are general guidance, not a substitute for the official fitting template. Facial shape and mask positioning affect which size works best.
If you have been comfortable with a medium cushion, there may be no reason to change sizes. If your mask has started leaking or causing discomfort, reassess the fit instead of automatically moving to another size.

Why Choose a Genuine Compatible Replacement?
A replacement cushion should fit the mask frame correctly and meet the manufacturer’s specifications.
An incompatible or poorly fitting part may create air leaks, discomfort, or difficulties during therapy. Before buying, check the manufacturer’s product information and confirm that the item is designed for your particular mask.
If you are unsure whether you have an AirFit N20, AirFit N20 Classic, or another ResMed mask, check the label, packaging, or original product documentation.
The name matters because different mask systems can use different replacement components, even when their designs look similar.
