1) Sometimes the leaks start to increase. It's not a big dramatic jump in the leak rate, though. Rather it's an increase in the little annoying leaks at the beginning of the night when I'm settling down. As the pillows age, it's easier to knock the mask out of place when I'm moving around in bed.
2) More pillow shifting tends to make my nose hurt more. Sometimes it's a dry nose, but more often than not, it's just sore from the pillows not staying where I want them. When the move around, the tippy-tip sometimes hit the inside of the nasal membrane and that can make it sore.
3) More chapped lips. Caused by the little annoying leaks that don't always show up in the leak graph.
4) A growing tendency of the inner cone(s) to collapse AND an increasing amount of effort needed to get that inner cone pointing back upwards the way it is supposed to.
5) Old pillows feel "spongier" in some hard to describe fashion.
6) More restlessness with no identifiable cause.
Agreed 100%. The only things I can really add to this are that the pillows should be replaced once per month according to the government pubs that they base things like Medicare on and so a lot of insurance companies base on this. Having said this, I feel it is a waste to replace that often, but everyone is different!
Another item that can cause issues is your headgear. Headgear is made primarily out of elastic. Elastic tends to stretch out and then break down over time making what was once a well fitting mask one that needs adjustment. Depending on who you talk to headgear should be replaced every 6 months to a year. Because the natural oils in hair hasten the breakdown of the elastic, I do agree with this and replace my headgear everytime my ins allows.
As always, YMMV! You do not have to agree or disagree, I am not a professional so my mental meanderings are simply recollections of things from my own life.
