AirTouch N20 vs AirFit N20: foam vs silicone

2 min read By HHZ Editorial Next review

The AirTouch N20 and AirFit N20 are the same nasal mask with different cushions: foam on the AirTouch, silicone on the AirFit. The foam cushion should be replaced monthly and only wiped clean, not washed. Specs are otherwise near-identical: 4–30 cmH2O, 24 dBA, magnetic clips. On ResMed's eShop on 13 October 2026 the AirTouch N20 was $108 and the AirFit N20 $105. This comparison is based on ResMed's user guide, not hands-on testing.

Cost over a year

The foam cushion’s monthly replacement adds up. On ResMed’s eShop on 13 October 2026, an AirTouch N20 cushion was $37 and an AirFit N20 cushion $34. Replacing the foam cushion monthly at that price is $444 a year. Check what your insurer allows: see CPAP supplies replacement schedule.

Who should pick which

You…Better fit
Prefer the feel of foam against your skinAirTouch N20
Want to wash the cushion dailyAirFit N20
Want lower running costsAirFit N20
Have a magnet-sensitive implantNeither; see AirFit N20 vs N30

Because the cushions are interchangeable, you can buy one frame and try both.

Verdict

These are one mask with two cushion options. Start with the silicone AirFit N20 for easy cleaning and lower cost; switch to the AirTouch foam cushion if you prefer foam, and budget for monthly replacements.

Frequently asked questions

What's the difference between the AirTouch N20 and AirFit N20?
Only the cushion. ResMed's guide says the masks are identical except for the interchangeable AirFit N20 silicone cushion and AirTouch N20 foam cushion.
How often should I replace the AirTouch N20 foam cushion?
ResMed recommends replacing the AirTouch N20 cushion every month, and sooner if it visibly deteriorates.
Can I wash the AirTouch N20 cushion?
No. ResMed's guide says to wipe the outside of the foam cushion with CPAP wipes or similar alcohol-free wipes, and its symbols say not to submerge it in liquids. The silicone AirFit N20 cushion is washed with the rest of the mask.
Is the AirTouch N20 quieter?
No difference on paper: ResMed lists both at 24 dBA sound power and 15 dBA sound pressure. The foam version has slightly higher resistance (0.4 vs 0.3 cmH2O at 50 L/min).
Which costs more?
On ResMed's eShop on 13 October 2026, the AirTouch N20 complete mask system was $108 and the AirFit N20 was $105. Foam cushions are replaced monthly, so running costs are higher.
