“Some tap water contains low levels of organisms – such as bacteria and protozoa, including amoebas – that may be safe to swallow because stomach acid kills them. But in your nose, these organisms can stay alive in nasal passages and cause potentially serious infections. They can even be fatal in some rare cases, according to the Centers for Disease Control and Prevention (CDC).”
What Types of Water Are Safe to Use?
- Distilled or sterile water, which you can buy in stores. The label will state “distilled” or “sterile.”
- Boiled and cooled tap water – boiled for 3 to 5 minutes, then cooled until it is lukewarm. Previously boiled water can be stored in a clean, closed container for use within 24 hours.
- Water passed through a filter designed to trap potentially infectious organisms. CDC has information on selecting these filters.
