That’s why our innovative silicone cushion adapts to your unique facial contours to deliver a secure and comfortable fit, regardless of your face shape and size. ResMed 2016 international studies found that our full-face and nasal InfinitySeal silicone cushions fit 96.5% and 99.4% of all patients tested.1,2,3,4,5 At ResMed we believe that performance is non- negotiable. A mask should seal firmly but comfortably. And it should not be a struggle to find a model that suits you. That’s why we developed our new AirFit 20 series of masks with InfinitySealTM cushion technology. It’s designed to fit the widest range of face shapes, and be easy to fit the first time and every time. Made to accommodate different fitting techniques and movement during therapy, the AirFit 20 masks are designed to perform well however you choose to wear it. ## The AirFit 20 Series From the #1 mask brand preferred by patients3 [![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/RESMED.jpg) ## Full face ![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/comparison_arrow.png) AirFit F20 ![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/image.png) - Clear field of vision for bedtime reading or watching TV - Comfortable frame designed to shape to your face - Women’s variant (for Her) available for more tailored therapy - Suitable for people who breathe through their mouth ](https://www.resmed.co.th/en-th/consumer/products/mask-series/airfit-20-series/airfit-f20) [![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/resmed%202.jpg) ## Nasal![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/comparison_arrow.png) AirFit N20 ![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/image%20(2).png) - Clear field of vision for bedtime reading or watching TV - Compact and comfortable padded frame - Women’s variant (for Her) available for more tailored therapy - Suitable for people who breathe through their nose ](https://www.resmed.co.th/en-th/consumer/products/mask-series/airfit-20-series/airfit-n20) [![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/Capture3.png) ## Classic Nasal![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/comparison_arrow.png) AirFit N20 Classic ![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/image%20(3).png) - InfinitySeal™ silicone cushion designed to seal robustly regardless of facial shape or size - Adaptive frame with forehead support is designed to automatically adjust mask tension in response to movement - Plush headgear designed for extra softness and stability - Classic Velcro™ tabs and slide-in hooks for simple, secure fitting ](https://www.resmed.co.th/en-th/consumer/products/mask-series/airfit-20-series/airfit-n20c) ## Still Available ![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/resmed%202.jpg) ## [Nasal Pillows ![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/comparison_arrow.png) AirFit P10](https://www.resmed.co.th/en-th/consumer/products/masks/airfit-p10) [![](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/cross-promotion.png)](https://www.resmed.co.th/en-th/consumer/products/masks/airfit-p10) - Clear field of vision for bedtime reading or watching TV - Split-strap headgear for easy adjustment - Women’s variant (for Her) available for more tailored therapy - Suitable for people who breathe through their nose ## Patient tested and preferred Crafted for confidence, each mask in our AirFit 20 series has been extensively tested to ensure an effortless, high-quality therapy experience. Recent ResMed studies have shown that, when comparing against the current market-leading full-face mask, 86% of all patients tested preferred the seal of AirFit F20, while in another ResMed study, 71% of patients tested preferred AirFit N20 to their current nasal mask.1,6 ## FAQ Why does it matter if I breathe through my mouth or my nose? Your type of breathing can affect your CPAP therapy, so choosing the right mask to match how you breathe while sleeping is important. For example, if you’re a mouth breather, we recommend a full-face mask, because therapy on a nasal mask may be less effective and less comfortable. How do I know which mask size is for me? You can print our sizing guides for [AirFit F20](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/Support%20Page/pdf/airfit-f20_fitting-template-web-mm_glo_eng.pdf) and [AirFit N20](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/Support%20Page/pdf/airfit-n20_fitting_template_row_eng.pdf) – specifically developed to help you determine which mask size is best for you. Alternatively, your CPAP clinician will size and fit you before you go on to trial or purchase a mask.For additional tips, see our sizing videos for [AirFit F20](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/1031815%20AirFit%20F20%20Vid%20Sizing%20Glo.mp4) and [AirFit N20](https://www.resmed.co.th/hubfs/Res-Med%20B2C%202019/B2C-Mask%20Series/1031802%20AirFit%20N20%20Vid%20Sizing%20Glo%20(Trad).mp4). ## The world’s smallest CPAP device In terms of overall size, ResMed’s AirMini is the most compact CPAP device ever manufactured.
