NeilMed SinuRinse is the best-selling sinus rinse brand in the US — millions of bottles sold, a product that's been on the market since 1996. ATO Health is a newer competitor with a key formulation difference: baking soda. This honest comparison breaks down the ingredients, cost, comfort, and science to help you decide which sinus rinse is right for you.

This is the most important factor in the comparison. Sodium bicarbonate (baking soda) acts as a pH buffer — it maintains the rinse solution at approximately pH 7.2–7.4, which matches the natural pH of healthy nasal secretions. Plain saline (sodium chloride + water) has a pH of approximately 5.5–6.0 — noticeably acidic.
Why does pH matter?
NeilMed's formula does not include baking soda in their standard SinuRinse packets. (NeilMed does make a separate "Sinus Rinse COMPLETE" product that adds hyaluronic acid, but this is different.)
If you rinse once daily: you use approximately 365 packets per year. At 100 packets per box:
Both NeilMed and ATO Health are quality products made in FDA-registered facilities. NeilMed built the sinus rinse category and has an excellent track record. However, ATO Health's baking soda-buffered formula provides a more comfortable rinse experience — the absence of burning makes it easier to maintain daily use, which is what produces long-term results. For people with sensitive nasal passages, frequent rhinitis, or those who've quit rinsing in the past due to discomfort, ATO Health is the superior choice.

This means the solution is pH ~5.5-6.0, which is acidic compared to healthy nasal secretions at pH 7.0-7.4. ATO Health includes pharmaceutical-grade baking soda for a buffered, body-pH solution.
ATO Health is better for sensitive noses. The baking soda buffering brings pH to 7.2-7.4, matching the body's natural pH and eliminating the burning sensation that acidic rinses cause. People with inflamed, irritated, or post-surgical nasal passages particularly benefit from the pH-balanced ATO Health formula.
Yes — ATO Health packets dissolve in 8 oz of distilled water and work with any rinse device, including NeilMed squeeze bottles, neti pots, bulb syringes, and powered irrigators. You can use your existing NeilMed bottle with ATO Health packets.
Baking soda buffers the solution pH from acidic (~5.5 with plain saline) to near-neutral (~7.4). At the right pH, nasal pain receptors are not activated — so there is no stinging, burning, or discomfort during rinsing. Most people who found nasal rinsing uncomfortable in the past switch to ATO Health and describe it as a revelation.
