The solution you put in your neti pot matters enormously. Use the wrong water source and you risk serious infection. Use the wrong salt concentration and you'll either burn your nose or get no benefit. Get the recipe right and nasal irrigation becomes a genuinely pleasant, effective daily health habit. This guide covers everything: the correct recipe, the science behind each ingredient, and why pre-measured packets like ATO Health are often a better choice than DIY.
The gold-standard DIY neti pot solution:
Dissolve salt and baking soda thoroughly in water. Use immediately or store in a sealed, clean container for up to 24 hours at room temperature (or up to 1 week refrigerated). Warm to body temperature before use.
For a single-nostril rinse (8 oz), use half the recipe: 1/2 tsp salt + 1/4 tsp baking soda + 1 cup water.
This is non-negotiable: never use unsterilized tap water in a neti pot or nasal irrigator.
In 2011, two fatalities in Louisiana were attributed to Naegleria fowleri (brain-eating amoeba) infections following nasal irrigation with contaminated tap water. While tap water is safe to drink (stomach acid kills these organisms), the nasal passages provide direct access to the brain via the cribriform plate — making nasal use of unsterilized tap water a genuine safety risk.
Safe water options for nasal irrigation:
Plain saline solution (salt + water, no baking soda) has a pH of approximately 5.5 — well below the 7.0–7.4 pH of healthy nasal secretions. This pH mismatch is why plain saline rinses often sting or burn:
Sodium bicarbonate buffers the solution pH to ~7.2–7.4. It's not a comfort luxury — it's pH chemistry. The 1:2 ratio of baking soda to salt in the recipe above achieves this buffering reliably.
Standard iodized table salt should not be used in nasal irrigation solutions. Iodine can irritate nasal mucosa and disrupt the natural bacterial microbiome of the nasal passages. The iodine also may react with mucin proteins. Always use non-iodized salt: kosher salt, pickling and canning salt, or pharmaceutical-grade sodium chloride are all appropriate.
The DIY recipe works well when done correctly — but here's where pre-measured packets like ATO Health have real advantages:
At approximately $0.09–0.12 per packet, ATO Health costs less than the measuring errors and ingredient purchases associated with DIY rinsing for most households.

Tap water can contain Naegleria fowleri (rare but fatal brain amoeba) and other microorganisms that are safe to drink but dangerous in the nasal passages. Always use distilled water, sterile water, or tap water that has been boiled for 1 minute and cooled.
Combine 1 teaspoon of non-iodized salt (kosher or pickling salt, not iodized) plus 1/2 teaspoon of baking soda in 2 cups (16 oz) of distilled or previously boiled water. Stir until dissolved. Use at body temperature. The baking soda is essential — it buffers pH to 7.4 and eliminates the stinging sensation.
Most burning from neti pot use is caused by pH, not salt concentration. Plain saline without baking soda is pH ~5.5 (acidic), which activates pain receptors in nasal mucosa. Adding baking soda raises pH to ~7.4 and eliminates burning. Too much salt (hypertonic) can also cause irritation by drawing fluid from nasal tissues.
For isotonic saline (same concentration as body fluids), use 1/2 teaspoon of non-iodized salt per cup (8 oz) of water. For a full 16-oz rinse, use 1 teaspoon. Add 1/4 teaspoon baking soda per cup (1/2 tsp per 16 oz) to buffer pH. Pre-measured packets like ATO Health provide exactly the right ratio in every packet.
