Introduction: Replacement Cushion for N20 Medium

A well-fitting, comfortable CPAP mask can greatly improve your sleep quality and help you enjoy a more restful night. If you use a ResMed AirFit N20 nasal mask, you may notice over time that the cushion is no longer as soft, air begins to leak, or it simply isn’t as comfortable as it once was. Such changes may indicate that it is time for a replacement.

Choosing the correct cushion for your medium-sized N20 mask helps ensure a comfortable fit without replacing the entire CPAP mask system. The medium replacement cushion is intended for users who require a medium size and is compatible with the ResMed AirFit N20 mask frame. It comes in three sizes: small, medium, and large. 

At Alfa Healthcare Supply Inc., we aim to make finding the right medical supplies easy and convenient. In this guide, you’ll learn about the N20 medium cushion, when to replace it, how to install a new cushion, and how to care for it to maintain comfort and performance

Whether you are replacing a part for the first time or performing routine maintenance on your existing CPAP equipment, this article will help you make the right decision.

What is a Replacement Cushion for N20 Medium?

A replacement cushion is the soft component of a CPAP nasal mask that rests against your nose. It helps create a comfortable seal between the mask and your face, allowing air from your CPAP machine to flow effectively during sleep.

The ResMed AirFit N20 features a flexible silicone cushion designed to provide a secure fit while you sleep.It comes in three sizes: small, medium, and large.

The Replacement Cushion for N20 Medium is designed for users who already use a medium-sized ResMed AirFit N20 nasal mask and need to replace their existing cushion due to regular wear, damage, or reduced sealing performance.

Instead of purchasing an entire mask system, you can simply replace an old or worn-out cushion while continuing to use the rest of the mask components, provided they are still in good condition.

Key Product Features

  • Medium size: Intended for users who require the medium AirFit N20 cushion.
  • Soft silicone material: Designed to provide a soft, comfortable contact surface against the face.
  • Replaceable design: Allows you to replace the cushion separately without needing to purchase an entirely new mask system. 
  • Designed for a nasal mask: Covers the nose rather than the mouth.
  • Easy Installation: Designed to fit securely into the compatible mask frame for simple replacement.
  • Reliable Mask Seal: Helps maintain a proper seal when the cushion is correctly positioned and fitted.

These features make the replacement cushion a convenient choice for users who want to continue using their existing CPAP equipment.

Why Replace Your AirFit N20 Medium Cushion?

During sleep, your CPAP mask cushion is regularly exposed to facial oils, moisture, and movement. Over time, these factors can cause the cushion to wear out, making it harder to maintain a comfortable and secure seal. 

Here are some key signs that indicate it may be time to replace your cushion.

1. Air Leaks Around the Mask

If you feel air escaping from the sides of your nose, it could be because the cushion is worn out, positioned incorrectly, or is the wrong size. Replacing a damaged cushion might help, but first, check whether it is fitted properly and if the headgear is adjusted correctly.

2. Visible Wear and Tear

Regularly inspect your cushion for cracks, tears, misshapen areas, or damage to the sealing surface. If you notice any damage, replace the cushion instead of attempting to repair it.

3. Reduced Comfort

If the cushion is not sitting properly or comfortably on your nose, it may require attention. Skin irritation can also occur due to straps being too tight, an incorrect size, or other issues related to the mask fit.

If your current cushion has worn out, replacing it with a new one may help; however, if the problem persists, further investigation is needed.

4. Regular Equipment Maintenance

According to ResMed’s guidelines, the AirFit N20 cushion should be replaced approximately once a month. This is a general recommendation, not a guarantee that every cushion will wear out at the same rate. Follow the instructions provided with your mask and heed the advice of your equipment supplier.

Replacing the cushion at the recommended intervals helps maintain your equipment’s performance and condition.

How to Choose the Correct N20 Medium Replacement Cushion

Before purchasing a replacement cushion for N20 Medium, make sure to verify your current mask model and cushion type to ensure compatibility.

Check Your Existing Mask

Check the product information or packaging for the name ‘ResMed AirFit N20’. Do not rely solely on appearance, as different ResMed mask models may look similar.

Confirm the Size

If your current AirFit N20 cushion is marked ‘Medium’ and fits well, then choosing a new ‘Medium’ sized cushion is generally a good place to start.

However, if you frequently experience air leaks from your mask or have difficulty wearing it, it may be worth re-evaluating how it fits. A ‘Medium’ cushion is not necessarily the best choice for everyone.

Distinguish AirFit N20 From AirTouch N20

Before purchasing, it’s important to understand the difference between the two cushions. 

The AirFit N20 features a silicone cushion, while the AirTouch N20 uses a memory foam cushion. According to ResMed, the cushions are interchangeable within the N20-compatible frame; however, you should verify the correct model and compatibility before completing your purchase.

If you prefer the original silicone design, ensure that you select the AirFit N20 cushion—be careful not to accidentally order a replacement for the AirTouch N20 instead.

How to Replace Your N20 Medium Cushion

Replacing the cushion is generally straightforward. Follow these steps to remove the old component and install the new one.

Step 1: Remove Your Mask

Turn off your CPAP machine and, if necessary, detach the mask from the air tubing. Remove the mask from your face and place it in a clean spot.

Step 2: Remove the Old Cushion

Hold the mask frame firmly. Gently pull the existing cushion away from the frame until it detaches.

Avoid using sharp tools or applying excessive force, as doing so could damage the frame.

Step 3: Inspect the Frame

Check the frame for cracks, damage, or any residue (such as dirt). If the frame is damaged, simply replacing the cushion may not resolve the issues with your mask.

Step 4: Prepare the New Cushion

Remove the new medium cushion from its packaging. Before attaching it, ensure that it is the correct model and size.

Step 5: Attach the Replacement Cushion

Align the cushion with the mask frame and press it into place according to the manufacturer’s assembly instructions. The AirFit N20 frame is designed so that the cushion can only be fitted in the correct orientation.

Check that the cushion is seated evenly and is securely attached.

Step 6: Reconnect and Check the Fit

Reconnect the mask to the tubing and put it on according to the instructions provided in the user guide. Adjust the headgear so that the mask fits securely, but ensure it is not too tight.

Turn on your CPAP machine and check for any air leaks. If air continues to leak from the mask or if you experience difficulty wearing it, refer back to the fitting instructions and seek assistance from your equipment provider or a healthcare professional.

How to Clean and Maintain Your N20 Cushion

Proper care can help keep your cushion clean and in good condition.

Clean It Regularly

For the AirFit N20 silicone cushion, ResMed recommends daily cleaning. Remove the cushion as instructed, wash it using a mild liquid detergent and lukewarm water, rinse thoroughly, and allow it to air dry away from direct sunlight.

Follow the manufacturer’s current instructions regarding the appropriate temperature, cleaning methods, and products that can be used.

Avoid Harsh Cleaning Products

Do not use harsh household cleaners, abrasive materials, or any other products that could damage the silicone. Before reassembling the mask, always thoroughly rinse off any detergent residue.

Store It Properly

Keep the cushion in a clean, dry place away from direct sunlight, excessive heat, and potential damage.

Inspect It Before Use

Check the cushion for tears, deformation, soiling, or any other visible damage. If its condition deteriorates or it no longer seals properly, replace it.

Keep in mind that cleaning and replacement serve different purposes. Even a thoroughly cleaned cushion will eventually need to be replaced.

Benefits of Buying a Replacement Instead of a Complete Mask

When the cushion is the only worn component, purchasing a compatible replacement may be more practical than replacing the entire mask.

Potential benefits include:

  • Convenience: You can replace the worn part without changing your complete mask setup.
  • Less waste: Keeping compatible, undamaged components in use can reduce unnecessary disposal.
  • Familiar fit: You can continue using a mask frame and headgear that already work well for you.
  • Routine maintenance: A replacement helps you address cushion wear as part of regular CPAP care.

These benefits depend on the condition of your existing equipment. If the frame, headgear, or other components are also damaged, additional replacements may be necessary.

Common Problems and Helpful Solutions

My New Cushion Still Leaks. What Should I Do?

Check that the cushion is positioned correctly and that the mask sits properly on your nose. Avoid overtightening the headgear. If leakage persists, check your size and seek assistance from your equipment provider.

Can I Reuse the Old Cushion?

You may continue using the cushion as long as it remains suitable for use according to the manufacturer’s instructions. However, do not use a cushion that is damaged, worn out, or unable to form a proper seal.

Does a New Cushion Come With the Complete Mask?

A replacement cushion is typically a separate component, rather than the entire mask system. Read the product details carefully to see exactly what it includes.

Can I Use a Medium Cushion if My Mask Currently Uses a Small Size?

Do not change the size simply because a different size is available. Choose a cushion based on a proper fit and the manufacturer’s sizing guidance. If your current size is causing issues, consult your equipment provider or a healthcare professional for assistance.

Final Thoughts

Caring for your CPAP mask is an essential part of a consistent sleep therapy routine. When your current cushion begins to show signs of wear, you don’t need to replace the entire system; instead, you can simply select the appropriate replacement cushion to continue using your familiar, trusted mask.

Before purchasing a replacement cushion for the N20 (medium size), be sure to verify your mask’s model and size. Additionally, confirm whether you require the silicone ‘AirFit N20’ cushion or the memory foam ‘AirTouch N20’ version.
