Great for mouth breathers!
I am not a doctor and do not suggest to do what I do.  As a new cpap user and a mouth breather I was told to use a full mask.  It leaks and I cannot get comfortable.  I switched to nasal pillows but knew I needed to keep my mouth closed to work.  There is a fancy product but it is small and not super comfortable.<br /><br />I cut a 2 inch piece of this tape and cover my mouth at bedtime.  Hold very well and my numbers are great.
