Introducing: Morf Nasal Mask

The Morf nasal mask has a unique ThermAcryl® seal that is heated and formed perfectly to the contours of each user’s face. Once formed to the face, the firm seal reduces pressure sores, mask movement and prevents silicone allergies. The durable seal extends the life of the mask reducing the need for frequent seal replacement.


First Personalized-Fit Nasal Mask on the Market

For decades, most CPAP mask seals have been made from silicone rubber. The silicone is formed into generic shapes and has to flex to fit individual users’ facial profiles. While this is fine for many users, some users find that the flexing can lead to pressure being applied to points on the face. Over the night, this small pressure can create pressure sores on the face or lead to irritation caused by an allergy to silicone.

“The goal was to create a mask that overcame these issues,” said AMI’s Director of Research and Development Alastair McAuley. The design uses a low temperature thermoplastic material, ThermAcryl,  that custom forms to the unique features of each user and sets into that shape, spreading the contact forces over a large area on the face.

Taking 10 minutes to custom fit, the seal is heated in hot water and forms to the unique contours of each user’s face. Click here to watch the fitting video.

While most will get the fit right the first time, the ThermAcryl seal has shape memory, so the seal can be reheated and return to its generic shape so it can again be refit as many times as necessary.


What makes this mask unique?

While custom masks that are cast or 3D printed are available and overcome these issues, they are very expensive and often not accessible to most CPAP users. 

The Morf is the first custom mask that is mass manufactured and therefore readily available through channels such as CPAP.com at pricing comparable to most CPAP masks. While the seal is rigid the fact that it is contoured to each user results in a comfortable and stable fit. This is the benefit of custom masks that to date have been very effective, but also very expensive. 

  • One Size Fits Most – The seal can be widened or narrowed to suit individual users when forming to the face.


  • Silicone-free, ThermAcryl® Seal – This technology enables users to customize the fit of the mask to their face and prevents silicone irritation.


  • Ease of Breathing – The inline tube connection reduces pressure drop to only 0.14cm @ 50 L/min, reducing the work of breathing.


  • Compact, Lightweight Design – The ThermAcryl seal material reduces the size of the mask improving vision and reducing claustrophobia. The Morf mask, including headgear,  weighs only 66g (2.33 oz).   


  • Quiet Vent – The Morf mask is very quiet, with a sound power level of only 23.7 dBA.


  • Short, Flexible Tube – The flexibility allows for different tube placement options, while the swivel at the end of the tube enables easy connection and disconnection of the main CPAP tube.


Where did the name ‘Morf’ come from?

The name Morf is a play on the word MORPH, which means: to undergo transformation. In the case of the Morf the seal undergoes a transformation to the facial profile of each user, it morphs from a generic shape into a custom fit.


Who will benefit most from using this mask vs. other masks in the market?

People that are experiencing pressure sores, silicone allergies or are claustrophobic will benefit from using the Morf Nasal CPAP mask, as the Morf helps to overcome these issues. It is very small in terms of width and the extent that it protrudes from the face which is ideal for side to front sleepers. The rigid nature of the seal enables the seal to extend inwards, towards the narrower frame while improving mask stability.
