Can contaminated water be rendered safe for nasal saline irrigations?

ConclusionsCarbon filtration reduces contamination but does not sterilize water and is thus unsafe for preparation of nasal saline irrigant. Boiling and UV treatment resulted in sterilization and are equivalent to purchased sterile water. Ultraviolet treatment was found to be safe, convenient, and a cost‐effective alternative to purchased sterile water.
