I must be in the minority of CPAP users who would use it even if I stopped having OSA. Why? A few reasons:

1. Sometimes I hardly notice it. Newer models are very quiet and portable. I'd even go as far as saying the mask is comfortable to wear, like a security blanket for the face.

2. Practically nothing filters out dust and cat hair better than my CPAP. An N95 mask might do better, but would be ridiculously uncomfortable by comparison.

3. It's a humidifier strapped to my face. No more discomfort trying to sleep through dry weather seasons.
