Why is distilled water used in CPAP machines?
A CPAP (or Continuous Positive Airway Pressure) machine keeps the airway open for people suffering from sleep apnea. It allows a more restful sleep and uninterrupted breathing throughout the sleep cycle. Using distilled water will ensure your machine a longer life.Mineral DepositsUsing distilled water will prevent the buildup of mineral deposits and prolong the life of the CPAP machine.ContaminantsDistilled water does not contain any contaminants that could be left in the CPAP after the water has evaporated.Where to FindDistilled water can be found at your local supermarket or big box store. Your local hardware store should also carry it.Other MaintenanceAside from using distilled water, the only other maintenance required is changing the filters on a regular basis.ConsiderationsBoiling water is not the same as using distilled water.
