Yeahhhhh my wife was on the fence about getting a CPAP for years. Finally got one and it dramatically helped! Until suddenly she got sick. And stayed sick until she stopped using it. Turns out it was the model you described and little shitty foam bits are not good for your lungs. Needless to say, she has not used any CPAP since. It sucks because even she said it helped, but she’s too scared of getting sick again to try a different kind.

Thanks medical capitalism!
