Distilled water certainly is the safest way but tap water mixed with salt in countries where it's safe to drink tap water in most cases should cause no harm either.
Salt works as a disinfectant when dissolved in water. When rinsing your sinuses you'll want to use saline water anyway because fresh water will hurt the mucous membranes in your nose.
- gilgoomesh 8y agoThat's bad advice. Common saline solutions are around 9g/L and won't kill most protozoa. http://www1.nencki.gov.pl/pdf/ap/ap574.pdf http://www1.nencki.gov.pl/pdf/ap/ap574.pdf Even at seawater-like concentrations of over 30g/L, it can take over 72 hours to sterilize water containing fresh-water protozoa. Boiling is the only practical way to sterilize water.
