Switching from F30i full face mask to a nasal mask like the Bleep?

I'd like to use the Bleep because my f30i (which is working well) is leaving a bad indentation in my hair and I'm afraid I'll start to lose the hair there. My AHI is usually below 1 and I'm doing well. Can I switch to the Bleep with little concern? Will I need a chin strap, and if so, is the Knightsbridge the best?

Thanks. I didn't know the hair thing was an issue but it's concerning given my young age and beautiful full head of hair.

Yes. It is possible.

Whether or not you end up needing to do something to stop the mouth breathing depends on just how bad your mouth breathing might be impacting your therapy effectiveness...or your sleep quality.

I know I mouth breathe a little...never for really all that long and rarely deep into large leak territory...and doesn't wake me up so I don't do anything to stop the little mouth breathing I might do. I found out a long time ago that sometimes the cure for a small problem can end up causing bigger problems.

Give it a try...evaluate your results and then decide if you might need to do something to reduce any mouth breathing leaks.

I've been using a CPAP full face mask for almost 20 years. I never had a dry mouth issue until 3 years ago when I switched mask brands. The new brand is a ResMed AirFit F20. On the old mask (that brand is no longer available) the incoming air stream was not lined up with my mouth but it is on the ResMed. To address this issue I fabricated a deflector from a plastic chair leg cap. Using a super strong double sided tape I attached the cap to the inside of my mask over the incoming air port. Now I don't have the pressurized air blowing directly at my mouth. It just swirls around inside the mask.
On the ResMed mask a 1-1\4 inch chair leg cap is what I used.
