Thank you Raybee.
I have a F20 (and am trying to get used to a F30).
Like 70San0, I too was struggling with the concept of taking off the plastic cover, ( and breaking it) which I thought would eliminate the ability to then cover the holes in the elbow with new material. How would you hold the replacement material in place??? You solved it: just replace the sound deadening material and leave enough of the cover still attached to the elbow to hold the new material. Congrats

I cut out the holes on each side of the plastic cover spanning 2 "ribs" plus a bit as your photo shows, really on the "top" and "bottom" as opposed to the sides and I was able to pull out "stuffing" quite easily with the tip of the box cutter and a paper clip.
I have been inspecting my F20 elbow for weeks now, if not months, (from right after this thread started), looking for signs of dark or mould by looking down through the mask end of the elbow in bright indirect light. All the holes looked clean and free from discoloration. I (thought I) could see right down the holes!! I didn't really believe it would happen to everyone including me.
But yesterday,
when I pulled the material out, I saw the same black dots of colour that you showed in your photo. Wow!!
Note to reader: you can't tell until you pull the material out!
Your not actually breathing through this blackness unless you turn the machine off but just the same it doesn't deserve to stay there.
Do we know what it is - this blackness? Could it be microscopic plastic and/or oil from the motor? How would we prove it to be mould?
Has anyone done the operation on a brand new F20/30 elbow to determine that the blackness isn't there from the start?
It surprises me that with all the members of this forum that we can't force a comment or an explanation out of Resmed.
