Distilled versus purified

What is the difference in distilled water compared to purified water? If I only have purified will it hurt me to breathe it in?

  1. I am a nurse that works in a hospital. I am a pap user so know you must used distilled water. The hospital i work at doesn't use distilled water. They use sterile water. The respiratory therapists say they are one in the same. I get it if they want to destroy the hospital machines, but I had a patient who used his own. The wife told them multiple times not to use sterile water, they still did. Even after she bought her own distilled water and brought it in, they would often still use the sterile water bc they could authenticate where it came from. One told me that hospitalsterile water is special sterile water. I just know if my machine got ruined bc the hosptal wasn't following manufacturer requirements. Id be mad

    1. I can see why that is so frustrating. All those minerals remain in sterile water and might damage the machine. I hope their water is at least low in minerials like calcium that can build up. - Lori (Team Member)

  2. That's a great question! They are very similar, as both are free of many contaminants that can be harmful to your health and to your CPAP machine. The main difference is that distilled water is free of all minerals, whereas purified water still contains some minerals (which can be healthy for consumption but can lead to mineral buildup in your CPAP machine and supplies)
