ClearUP is wonderful!
I've bought two ClearUP devices--one for myself, and one for my dear cousin's husband. She expressed interest in it for her husband when I raved about mine. I've had sinus problems, spurred on by allergies and asthma, for decades. When I was younger, I used sinus medications, but now as an older person with (treated) high blood pressure as well as a permanent immunodeficiency, I can no longer take them, and the immunodeficiency almost guarantees resulting sinus infections. Mucinex helps to thin out secretions, but it's the ClearUP that seems to be helping drain my sinuses most often, and seems to prevent some of the infections. I couldn't be more pleased. My cousin's husband is reporting progress as well--less coughing.
