Hello everyone, I've been lurking for a while now, but I can't seem to find any info on this issue, so I guess I'll make a post.
I recently got a new F20 ffm and the first couple of nights were great. I'm talking beyond great. Then, suddenly, not so great. Last night it started whistling so bad, I had to use my old F10 it replaced. I couldn't really pinpoint where the whistle was coming from, but it was silent when I switched to the F10.
Next issue that I noticed a few days after I started wearing it was mask part disconnects from the headgear extremely easily. I'm talking it will fall apart in my hands if I am not careful with it. I can't just pick it up by just touching the headgear. I can hear a click when I push the mask into the headgear, but it just falls back out after moving it.
Anyone else with these issues?
Sorry if this isn't where I should post this at.
You're posting in the right place.
I assume you are referring to the magnets. I have an F20 and find the magnets hold quite well. I had to fiddle a little with it to eliminate leaks at first but now I don't usually have a problem getting a good seal. It has the lowest leak rate of any mask I have used.
Have you changed the Velcro adjustments? Occasionally I will forget and loosen the Velcro rather than detach the magnets and then I will have leaking until I get the adjustment right again.
You state unsure for your pressure. My pressure range is 8-14. I've never tested the F20 at a higher pressure.
Sorry I can't help you beyond what I've suggested.
