Resmed F40 Headgear swap out

[Anna Bee]

I love my Resmed f40 facemask but, after trying all sizes, I hate the straps on the headgear. They don't sit right on my head. Can I use the  f30 headgear? To clarify, it does not have to be a perfect fit. Just better than what I have. What other headgear is compatible? 
Thanks,
Anna

For most, when it comes to face masks and headgear, it's pretty much hit or miss. I make do with three masks. The AirFit F20, F30, and F40. 

My favorite is the F30. But, when I feel I need a change, that's what I do. 

Give it a try and see if you can make it work. Let us know how you did.

Possibly, though the F30 headgear is essentially one size fits all, which is fine for those with larger heads, but was consistently too big for me

Anna Bee,

I also have some issues with the F40 headstraps, and my solution was to modify one of them.  For me, the problem was the difference between the strap going over the head, and the straps holding the mask in place.  If I used a large strap to accomodate the over-head strap, it made the mask straps too short to tighten.  If I used a small headstrap it would tighten well, but would pull the mask up into my nose which would eventually cause pain.

So, my solution was to lengthen the over-head strap by cutting it and using superglue to attach an extender.

For me, I wish Resmed would have just allowed the over-head strap to be variable as they do with other masks.  But....

Anyway, hope this helps.
