ResMed Airfit N20 Nasal CPAP Mask with 6 Cushions

For Reference Only
Product Details

AirFit N20 CPAP Mask with 6 cushions by ResMed With Headgear 

Unlike a typical CPAP mask with one cushion, this N20 mask comes with 6 cushions (all same sizes) in one package with little extra cost. If you prefer a single cushion package, you can purchase it here.

InfinitySeal™ Nasal Cushion

The ResMed AirFit N20 Nasal Mask seal is suited to fit 99% of all unique facial structures and provides some of the best comfort for your sleep apnea therapy. With specially-designed loops and varied thickness, this design helps prevent leaks or blowout.  

Multiple Sizes Available

The AirFit™ N20 is available in multiple sizes and there is a size gauge available so you can determine which would be the best fit for you.

Soft and Flexible Frame/Magnetic Clips

The  AirFit™ N20 comes with a soft, plush headgear and a flexible frame which sits underneath your eyes and allows clear visibility for when you want to read a book or sit up and watch TV. The frames adapt to different face types while the integrated padding offers softness for a better night's sleep. One of the most popular features to the mask are the magnetic clips which guide the headgear to the frame quickly and easily.

Quick Release Elbow

The quick release elbow makes it easier for you to disconnect and reconnect the mask from the tubing without having to take the complete mask off, allowing you to get up during the night without having to worry about readjusting any straps.

How often should you replace the AirFit™ 20 mask?

We recommend that you replace the silicone cushion every 1 month. Mask tubing should be replaced every 3 months, and the headgear should be replaced every 6 months.

How to find out what mask size you would need for the AirFit™ 20 series?

The AirFit™ series has a size gauge template available on the Size Gauge tab to make sure you find the best fit for you.  

Note: the N20 cushion is interchangeable.  Different cushion sizes are compatible with the same N20 mask frame.

This mask is cheaper than competitors and does the job well. I recommend it.

Very minimal leaks so far from this mask. Comfortable cushion with a good seal. Stays in place throughout the night. The straps and headgear are unobtrusive and I can wear it when I'm watching tv. In the morning, I used to get some marks from this mask but after a looser adjustment (but without any leakage problems whatsoever), the problem went away.

I used to get about 5 hours of sleep a day but now I can consistently get about 7-8 hours of uninterrupted sleep every night. This is a huge improvement for me. I can't express how grateful I am for this mask. My days have been so much better with quality sleep. I finally think I can share a bed with my partner again.

Thank you very much Respshop. Such a good selection of masks and CPAP products. You have a new customer out of me.

Finally, a nasal mask that works well for me! The Airfit N20 is unlike the other masks I have tried where the nose sits in a silicone “pillow.”� This worked OK for me, but I consistently had leakage and was awoken to hissing around my nose. The N20 fits tightly and encloses the nose, so it’s not up against the nostrils. I find it extremely comfortable and have been able to use it every night with very little, if any, leaks. I highly recommend trying this mask.

The ResMed N20 nasal mask is a huge improvement, over my previous nasal mask. Great product build, fully adjustable headgear and interchangeable nasal pillows. Sleeping much better. Would recommend this product.

I like the mask. It wears well. The offer for additional cushions was too good to pass.

What if I am a mouth breather? Will the nasal pillow mask work with an 8.5 force setting without leaks?

Mouth breather will have leak if you use nasal pillow or nasal masks. You have two options: 1) chin strap; 2) full face mask.
