Most Jal Neti advice is about comfort and technique. This article is about safety, and it is the one piece we would ask you to read even if you buy your salt from someone else.
The rule
Use only water that has been boiled and then cooled to lukewarm, or water that is distilled or sterile. Never pour untreated water straight from the tap into your nose.
Why swallowing it is fine but rinsing with it isn't
Your stomach is an aggressively hostile environment. Its acid neutralises most organisms present in municipal water at the low concentrations found there, which is why drinking tap water is generally uneventful.
The nasal cavity has no such defence. It is a warm, moist environment with a direct mucosal surface, and organisms that would be destroyed in the stomach can survive there. This is why health authorities worldwide issue the same guidance for nasal irrigation regardless of how safe the local drinking water is.
This applies everywhere, to every brand. It is not a claim about Indian water quality specifically, and it is not a way of selling you something. The guidance is identical in countries with very high water-treatment standards.
How to prepare water correctly
- Boil it. Bring the water to a rolling boil for three to five minutes.
- Cool it. Let it come down to lukewarm — close to body temperature. This takes longer than you expect; plan ahead rather than rushing it.
- Store it properly. Boiled water kept in a clean, covered container is fine for up to 24 hours. After that, boil fresh.
- Then add the salt. One level 5 g scoop per 500 ml, stirred until completely clear.
Distilled or sterile water bought sealed is equally acceptable and saves the waiting. What is not acceptable is filtered-but-unboiled tap water, RO water straight from the unit, or bottled mineral water that has not been sterilised.
A note on the pot itself
Clean water in a dirty pot is not clean water. Rinse the pot after every use and let it air-dry completely — a damp, closed pot is exactly the environment you have just gone to trouble to avoid. We covered this properly in how to clean your neti pot.
And never share a pot. It is a personal item, in the same category as a toothbrush.

Take this. The technique can be imperfect and you will simply find it uncomfortable. The water being wrong is the only part of Jal Neti with a genuine safety consequence attached, and it is entirely within your control.
