ResMed airsense 10 elbow leak?

[Teddysjam]

I have an ResMed air sense 10 using an Airfit 20 full mask with cushion mask. It’s generally quiet while on I can hear small air coming from elbow where’s it’s attached to mask nothing unusual but past 2 nights I noticed more air flow coming from elbow a lot louder and wife even noticed it woke up with the sad frown face for bad leaks not sure what’s going on. Been using for like 5 month so never had an issue with leaks or anything just past 2 nights I have no clue.

I have the same setup, AS10 - Airfit 20, I had an air leak issue one night and so I tore the setup down and cleaned it with vinegar water. I noticed some of the small vents had clogs so I had to carefully clean them with a toothpick and flushing water. I also noted the flaps in the elbow were not flipping up all the way and so I cleaned the back of them thru the openings with a q-tip.

I'm not a dirty guy, I use my SoClean every few days, but it had some stuff in there, all I can figure is I had a stuffy nose and maybe I sneezed in the mask at a low pressure point and it gummed up. I also know that if I put the covers over the mask, or the mask into the pillow it can make the frowny but its so loud in my head that it wakes me up and I fix the situation. Hope you get your issue figured out, but if its loud and in the elbow most likely the flaps are getting stuck and not opening all the way to block off the openings in the elbow.
