It depends on the individual. I've been on a Bipap ASV for eleven years. I go through about a pint of distilled water every week with my TapPap mask.Guinges wrote: ↑Sat Dec 07, 2019 6:13 pmI have been thinking about why some people may need humidification and others might not. Could it be related to the degree of mouth leak that is occurring? Mouth leak is said to be fairly common. If it was occurring, to any degree, then airflow through the nose and mouth would indeed be greater than normal breathing, leading to dryness of the nose and mouth and rhinitis etc.
My husband is new to his AutoCPAP. We're attempting to get his leak rate under control. He uses half the distilled water that I do, never mind whether he's using the TapPap, the Mirage Liberty, or the P30.
