Nasal Pillows vs. Full Face Mask

[snorybob]

I had the same problem with the resmed liberty, after a while the mouth piece would slide to much upward toward the pillows and it hurt and leaked. I used 2 clips from an amara view , filed down the little lump in the middle , assemble with a 4 to 5 inch of velcro  then put your mask on ,slide one clip between your cheek and attach the bottom strap go under the chin and do the same on the other side , ajust the velcro just to be tight enough   not to much.  
Once you have the right adjustment , cover the velcro with a piece of cloth (smooth side of velcro still a little itchy) and your all done .
Hopefully you will understand this ,I would put a picture but do not know how to do it , another thing ,I have never tried it with your f20 (magnets)
but it dont take much to keep the mask from sliding up.

I know you do not want a chin strap but it's nothing like it (mini chin strap)

I just wanted to chime in on taping. I can't find a full face mask that fits, and my mouth always falls open. I use NexCare durable cloth tape, but I have to tape two pieces together to get about an extra 1/4" of height to keep my mouth completely closed. I've been doing it for a few years now, and hope someone comes up with a better solution, but this one does work perfectly for me.

Beside chinstrap, tongue sucking technique , and medical 2 inch tape , check the innomed /respcare hybrid mask .

It might work for you ! The mask has an incorporated  chin (mouth ) holder.

I forgot to mention one of the most effective option for a lot of people (witch you probably know about) the cervical collar ,is another option !

Thanks. I use the chin strap and the tape (1" made into 1 1:4"). Cervical collars didn't work for me. I'll check out that mask.
