Philips 1137366 Respironics Wisp Nasal Lab Mask Fabric Frame Small-Medium

• Model: 1137366
• Size: Small-Medium
• Nasal Lab Mask
• Frame: Fabric 

The 1137366 Wisp Nasal Mask in the Small/Medium size with fabric frame delivers a balance between comfort, minimal contact, and sufficient coverage. Unlike full face masks or masks with large forehead supports, the Wisp has no forehead pad, which opens up the field of vision—helpful for those who want to read, watch TV, or wear glasses before bed. The fabric frame option is soft and more skin‑friendly: one side cushioned suedette, the other silky sateen, which helps reduce irritation especially for people who feel discomfort from plastic edges. The overall design is lightweight and compact, so it feels less intrusive on the face.

Because the cushion sizes are interchangeable on the frame, getting a good seal is more about picking the right cushion (in this case small/medium for many mid‑sized faces) than having a different whole mask. The small/medium cushion paired with the fabric frame tends to reduce pressure and weight, which helps with comfort especially for side sleepers or people who toss and turn. The minimal contact around the nose (no forehead bar, smaller frame) also helps reduce red lines or marks after wearing, and the magnetic or click‑on clips make putting it on or taking it off more convenient. 1137366

On the downside, minimal design can sometimes be more sensitive to small misalignments: if the cushion isn’t aligned properly, leaks can occur more easily than with masks that have more support points. Also, fabric frames are more susceptible to wear from moisture over time—sweat, skin oils, cleaning agents—so regular cleaning and inspection is essential to maintain performance. Noise can also increase if cushion or cushion seal degrades. Finally, the lack of a forehead support makes the mask’s seal more dependent on the elasticity and fit of the headgear, so ensuring the headgear is adjusted well (not too tight, but snug enough) is important. If the pressure prescription is high, some users may feel more airflow sensation since more of the force is concentrated on the nose cushion and less supported by frame / pad structure.
