Reviews Summary
Customers say this mask fits comfortably and seals well with minimal leaks. Many appreciate the hybrid design that covers the mouth without extending over the nose bridge, reducing claustrophobia compared to full-face masks. Users find it easy to clean and note the quiet vent design. Some mention it requires a snug fit to prevent leaks, and a few report the cushion durability could be better. Overall, customers praise the comfort and effective seal, particularly for mouth breathers seeking an alternative to traditional full-face masks.

    RESMED F40 Full Face

    I had F20 Full Face several years before F40 was available. There were irritation issues with my temples, eyes and nose over time. The F40 system solved all that and cushion seals effectively Extra flexy hose allows me to sleep on my back or either side with no problems. There may be better solutions, but I'm quite satisfied with the F40.

    ResMed AirFit F40 mask

    For a larger face the mask works better than any other mask that I have used. Once you get used to the nose attachment it works perfect. I am also able to watch TV or read without limited vision.
