I heard a sound that I didn't expect from my hose the past couple of nights. When I breath in it sound like a crackle or collapsing sound from the hose. Is this normal to hear? It doesn't persist for very long but I wanted to make sure it was normal.
I also experienced what I think was rainout last night. I woke up a few times in the night with water being on my neck. I believe that it was from the seal that goes around my mouth/chin from using a FFM.
I think that this may be from pushing up the humidity in the middle of the night. I had woke up and my nose felt stuffy, so I increased it from 6 to 8 to see how it would work. I also noticed water vapor and maybe a droplet or two in the mask when I got up this morning.
I will continue to monitor this to see if I continue to have anymore issues. I will drop the humidity back to down to either 4 or 5 tonight. If it doesn't clear up then I may get something to put over the hose or look into a climate-line hose. Thanks!
