I'm relatively new to this CPAP life, but after four months of using a CPAP machine and trying out four or five different masks, the ResMed AirFit F30i has been working really well for me and I'm actually (hoping I don't jinx anything here), becoming somewhat fond of it. I hesitate to write a review among other folks who have so much more experience, but I haven't seen too much about this particular mask, so thought I'd give it a go.
(Some background: I'm a 100% side sleeper, tend towards claustrophobia and feel I need the option to mouth breathe, although my goal is to get over that last limitation. Regardless, when it comes to full-face masks, the "hybrid" style suits me best and there are not too many options out there. ResMed calls the F30i a "full face" mask, but I believe it also fits into the "hybrid" category.)
What I like about it:
* The top-of-the-head hose - don't just like it -- LOVE it
* The mask itself fitting UNDER my nose and leaving the top of my face clear for
wearing glasses and reading in bed, etc.
* The mask is narrow enough that side-sleeping doesn't cause my pillow to push it off-kilter and
allow more leakage
* The stretchy air-tube frame which I find comfortable against the side of my face for sleeping
* The shape of the nasal part of the mask fits higher up the outside of my nose and prevents
almost all leaks there, with nasal holes that allow plenty of airflow
* The pillowy, very soft silicone under the bottom of my nose and in an area between my mouth
and chin
* The sturdier/firmer silicone around the rest of the mask which keeps its shape and
holds it in place for side-sleeping
* The fact that with such minimal facial covering, I can breath through my nose OR my mouth,
and I feel like there is plenty of fresh air moving around
* Simple headgear that is adjustable and stays in place
* Features like the magnetic tabs on the bottom straps and quick-release swivel elbow to tube
What I don't like about it or could see being a negative to some people:
* There is a good amount of air vented out of the mask from the clear plastic mouth area.
I sleep hot so the cool air feels good to me, but it might bother some people
* Replacement parts are ridiculously expensive without insurance and not much available on
Amazon
(Note: I had previously used the Dreamwear Full Face mask which is very similar and I was and still am a fan. However, I feel the Airfit f30i is sturdier overall so stays in place better for a side sleeper, the nasal area is shaped in a way to prevent more leaks, and the slightly narrower mask of the f30i also keeps it in place.)
