Here are the published recommendations from two authoritative sources regarding water used for saline nasal irrigation:
- The US FDA advises using filtered, distilled, or previously boiled water for nasal irrigation.
- The US CDC provides detailed information about boiling, filtering, and disinfecting water for nasal irrigation at www.cdc.gov.
Most users prefer to warm their water prior to use. If you do this, do not overheat the water. It should be lukewarm to the touch and not hotter than about 85°– 90° F (29°– 32° C)
