A. Water usage varies based on humidity setting, therapy pressure, hours of use, environmental dryness, and especially mask leaks. If the PAP detects a leak, it increases airflow to maintain pressure, which causes the humidifier to use significantly more water. Check your mask fit and replace cushions as needed. An RT at your local branch can review your usage data to determine exactly what’s causing the increased consumption. Extremely dry household air or high humidity settings can also reduce water duration.

A. It is recommended you use distilled water for 2 reasons. To protect the equipment and to protect your lungs. Spring or tap water has minerals that will collect in the chamber and damage the humidifier or affect the function of your equipment. Spring and tap water also has bacteria and other microorganisms that can become aerosolized and inhaled. For routine use, always use distilled water to avoid respiratory and equipment issues.
