From what I’ve heard, it was those CPAP cleaning machines that caused the foam to degrade and cause problems. Those who never used those things never had a problem.
That’s what I’ve been lead to believe anyway. I took mine apart before sending the recalled one back and it was like new even after years of use.
I don’t see how Philips could have foreseen this happening.
That’s interesting. I’ve not heard or seen that reported in the news articles I’ve read. I’ve never used any cleaning solutions or machines with my ResMed and I probably won’t. I keep it clean and dry when not in use during the day.
