[split] F40 Full Face
F40 update:
A few weeks into F40 use it seems my Large Leak problems may be solved even though I have a beard. I see that one reason this mask seals well and has a higher comfort level is its flexible construction with no hard rigid plastic on the cushion or the cushion bracket.
The short very flexible tube from the mask to the long tube is a big improvement over having the thick stiffer long tube right at the mask. I must move from side to side to sleep. A flip of the thicker long tube (I use the heated tube) from one side of the pillow to the other puts the short tube into a good position.
I have to use humidity at least on level 2 with the F40 to prevent nose bleeds due to the nasal design of this hybrid mask. Perhaps with winter coming my in-house humidity level will rise allowing me to turn humidity off.
I appreciate the minimal headgear of the F40. For the first time in 17 years, I have a mask/headgear I do not struggle to put on. I no longer continuously adjust uncomfortable straps. I do not have to over-tighten the F40 straps to get a seal. I do not have to remove the headgear and reposition it trying to stop irritation.
The F40 airflow passages to the nose are an improvement over the FP Evora FF mask. I no longer get the feeling that the mask is not aligned with my nostrils. I tried mouth taping with each mask with no improvement in AHIs.
It took 17 years but finally, a mask that works much better with my face has arrived. It is misleading to call the F40 a full-face mask. I have only found one mask, the ResMed Fit Life, to cover the face. The F40 is like a nasal mask with mouth-breathing backup.
