I guess I’m just the sort of person who can’t get along with nasal pillows. I’ve tried different ones before and was hoping this one would be different. I just don’t feel like I am getting enough air and I feel as though I’m suffocating. As a result I end up mouth breathing, which doesn’t help anything. I’m going to stick to my AirFit N 20, even if it does leak some. At least I can breathe.
