Prevents nighttime nasal mucous buildup
Works as promised. As a person living with Cystic Fibrosis, and needing to wear nocturnal oxygen, and having classic narrow nares of a chronically under nourished person, these prevent me from having dry mucus buildup in my nostrils from the traffic jam between the nasal cannula and my nose. I really love these. Not uncomfortable, and when I use them in conjunction with mouth taping, I feel like my nitrous oxide really gets manufactured and better oxygenates my whole body. Kind of a natural cpap, which I don’t have sleep apnea severe enough to qualify for cpap (whew).
