Replacement Cushion for N20:
Using a CPAP machine every night can become an important part of your sleep routine. However, even when your machine works well, an old, loose, or damaged mask cushion can make sleeping less comfortable. Air leaks, pressure marks, and an unstable mask may interrupt your rest and make your therapy harder to manage.
A replacement cushion for N20 can help restore the fit of your compatible ResMed nasal mask without requiring you to replace the entire mask assembly. Choosing the correct size, cleaning the cushion regularly, and replacing it when it becomes worn can help you maintain a comfortable mask fit.
At Alfa Healthcare Supply Inc., we understand that finding the right CPAP supplies should be straightforward. This guide explains what to look for when choosing a replacement cushion for N20, how to install it, and how to care for it as part of your regular sleep routine.
What is a Replacement Cushion for N20?
A replacement cushion for N20 is the removable part of a compatible ResMed N20 nasal CPAP mask that rests against your nose. It creates the seal between your face and the mask, helping direct the prescribed airflow into your nose during sleep apnea therapy.
The original ResMed AirFit N20 uses a silicone cushion with InfinitySeal technology. Its flexible design is intended to adapt to different facial shapes and help maintain a seal while you move during sleep.

Instead of buying a complete new mask whenever the cushion becomes worn, you may be able to replace only this component. This can be a practical option when the mask frame, headgear, and other parts remain in good condition.
It is important to check compatibility before ordering. The AirFit N20 silicone cushion is designed for the AirFit N20 mask family, while the AirTouch N20 uses a different foam cushion. ResMed also offers an AirTouch N20 cushion that is compatible with the AirFit N20 frame. Always confirm the specific product and size before purchasing.
Why Should You Replace Your N20 Cushion?
Over time, daily use, facial oils, cleaning, and normal wear can affect a CPAP cushion. Even if the cushion looks acceptable at first glance, it may no longer provide the same fit.
Here are common reasons to consider a replacement cushion for N20.
1. Air Leaks Around the Nose
A cushion that has stretched, lost its shape, or developed damage may not seal properly. You might hear air escaping around the edges or notice airflow reaching your eyes.
A new cushion in the correct size may help restore the seal. However, leaks can also result from incorrect headgear adjustment, poor positioning, or an unsuitable mask size.
2. Visible Wear and Tear
Inspect your cushion regularly for cracks, tears, permanent deformation, or other signs of deterioration. If the material is damaged, replacing it is generally better than continuing to use a compromised component.
3. Skin Discomfort
A cushion that no longer sits correctly may contribute to redness, pressure marks, or irritation around the nose. Skin discomfort can have several causes, including excessive strap tension and sensitivity to materials.
A correctly fitted replacement may improve comfort, but persistent irritation should be discussed with your healthcare professional.
4. Difficulty Maintaining a Reliable Seal
If you repeatedly adjust your mask during the night, check the cushion for wear and make sure it is seated correctly in the frame. A replacement cushion for N20 may be appropriate if the existing one no longer fits as intended.
Remember that replacing the cushion will not automatically resolve every leak. Check the mask fit and machine settings with your care provider if problems continue.
Key Features to Look for in an N20 Replacement Cushion
Before purchasing, review the product details to ensure that the cushion suits your mask and needs.
Silicone Cushion Design
The AirFit N20 replacement cushion is made from silicone. Its flexible design helps it rest against the nose while accommodating normal movement during sleep.
InfinitySeal Technology
ResMed’s AirFit N20 cushion uses InfinitySeal technology, which is designed to provide a dependable seal across different facial contours and prescribed airflow pressure settings.
Multiple Size Options
The AirFit N20 cushion is available in three sizes:
- Small: For users who require a smaller cushion according to the manufacturer’s sizing guidance.
- Medium: For users whose measurements and mask fit correspond to the medium size.
- Large: For users who require the larger cushion size based on the sizing guide.
Do not select a size based only on the size of your nose or your general body size. Refer to the manufacturer’s fitting guide and your existing mask specifications.
Replaceable Design
The removable cushion allows you to maintain your compatible mask without automatically replacing the frame and headgear. This can reduce unnecessary waste and make routine mask maintenance more convenient.
How to Choose the Correct Replacement Cushion for N20
Selecting the correct cushion is essential for comfort and a proper seal. Use these simple steps before ordering.
Step 1: Confirm Your Mask Model
Check whether you use a ResMed AirFit N20, AirFit N20 for Her, or AirTouch N20 mask. These names are similar, but their cushion materials and product specifications differ.
Step 2: Check Your Current Cushion Size
Look for the size marking on your existing cushion. It may be identified as Small, Medium, or Large, or by the corresponding letter.
If the current cushion has never fitted well, do not assume that buying the same size will solve the problem. Review the manufacturer’s sizing guide or ask your equipment provider for assistance.
Step 3: Inspect the Mask Frame
Make sure the frame is not cracked or damaged and that the cushion can attach securely. If the frame itself is worn, a new cushion alone may not restore the mask’s fit.
Step 4: Review the Product Description
Before ordering a replacement cushion for N20, check the manufacturer’s name, compatible mask models, cushion material, and size. Confirm what is included in the package so you know whether you are purchasing a cushion only or a larger mask assembly.
How to Replace Your N20 Cushion
Replacing the cushion is generally simple when you follow the instructions for your exact mask model.
- Prepare your mask. Turn off the CPAP machine and disconnect the mask from the tubing as appropriate for your setup.
- Remove the old cushion. Hold the mask frame securely and gently pull the cushion away from it.
- Inspect the frame. Check for cracks, residue, or other damage before installing the new part.
- Fit the replacement. Align the new cushion with the frame and press it into place according to the manufacturer’s instructions.
- Check the connection. Make sure the cushion is seated evenly and securely around the frame.
- Refit your mask. Put the mask on and adjust the headgear without overtightening the straps.
- Check for leaks. Start your prescribed therapy and check the seal according to your machine and mask instructions.
If the cushion does not attach easily, stop and check its model and size. Never force a component into place.
For detailed, model-specific instructions, consult the official ResMed AirFit N20 user guide.
How Often Should You Replace an N20 Cushion?
The right replacement schedule depends on the manufacturer’s guidance, the condition of the cushion, your cleaning routine, and your insurance or equipment-supply arrangements.
ResMed’s US online shop lists a monthly replacement guideline for the AirFit N20 cushion. This is a useful reference, but your individual replacement needs and coverage may differ.
Consider replacing the cushion sooner if you notice:
- Tears, cracks, or other visible damage.
- A persistent loss of seal despite correct fitting.
- Material that has become misshapen or difficult to clean.
- Ongoing discomfort associated with a poorly fitting cushion.
Regularly checking your cushion is just as important as replacing it on schedule. If you notice visible damage, replace the cushion promptly rather than continuing to use it until the planned replacement date.
Tips for Cleaning and Maintaining Your N20 Cushion
Good cleaning habits help remove facial oils and everyday residue that can affect the mask’s condition.
Clean It Regularly
Follow the manufacturer’s cleaning instructions. ResMed recommends cleaning the AirFit N20 cushion after each use with warm water and a mild liquid detergent.
Rinse Thoroughly
Rinse away all detergent residue using clean, drinking-quality water. Leftover soap may irritate your skin.
Let It Air-Dry
Set the cushion on a clean surface and let it air-dry away from direct sunlight. Avoid high heat, which can damage the material.
Avoid Harsh Cleaning Products
Do not use strong chemicals, abrasive cleaners, or products that are not approved for your mask. Follow the official care instructions for your particular cushion.
Inspect It Before Bed
Take a moment to check the cushion for damage and make sure it is attached properly. A quick inspection can help you identify problems before settling down for the night.
Replacement Cushion for N20 vs. Buying a New Mask
Do you need a new cushion or a complete mask? The answer depends on which component is causing the problem.
A replacement cushion may be enough when:
- The cushion is worn or damaged.
- The frame and headgear remain in good condition.
- You are satisfied with your current mask model.
- You can obtain the correct compatible cushion size.
A complete mask or additional parts may be necessary when:
- The frame is cracked or damaged.
- The headgear no longer holds the mask securely.
- Several components show signs of wear.
- The mask continues to fit poorly despite a new cushion and proper adjustment.
If you are unsure which component needs replacing, ask your equipment supplier or healthcare professional to assess the mask.
