50+ answers to the most common questions about nasal irrigation, neti pots, saline rinse safety, and ATO Health Sinus Rinse Packets.
What is nasal irrigation? Nasal irrigation (also called nasal rinsing or nasal lavage) is the practice of flushing the nasal passages with a saline solution to remove mucus, allergens, and irritants. It is a well-established, drug-free method for managing sinus congestion, allergies, and upper respiratory symptoms.
What is a neti pot? A neti pot is a small container with a spout designed to pour saline solution into one nostril so it flows through the nasal passages and out the other nostril. It is the most traditional tool for nasal irrigation. Squeeze bottles are a more modern alternative that some people find easier to use.
Is nasal rinsing safe? Yes, when done correctly with the proper water source, nasal rinsing is safe and effective. The key safety requirement is using distilled, sterile, or previously boiled water — never tap water.
Who can benefit from nasal rinsing? People with seasonal allergies, chronic sinusitis, post-nasal drip, nasal congestion from colds or flu, dry nasal passages, and those recovering from sinus surgery all commonly benefit from regular nasal rinsing.
How old do you have to be to use a neti pot? Children as young as 2 can use nasal rinsing with appropriate technique and equipment. Always consult a pediatrician for children under 4.
What kind of water should I use? You must use distilled, sterile, or previously boiled water. Never use tap water, well water, or filtered water from a standard household filter.
Why can't I use tap water? Tap water may contain microorganisms that are harmless when swallowed but can cause serious illness when introduced directly into the nasal passages. The FDA and CDC both explicitly warn against using tap water for nasal rinsing.
Where can I buy distilled water? Distilled water is available at virtually all grocery stores, pharmacies, and big-box stores. It is typically sold in 1-gallon jugs for about $1–$2.
How should I boil water for nasal rinsing? Bring water to a rolling boil for at least 1 minute (3 minutes at elevations above 6,500 feet). Let it cool to lukewarm before using.
Can I use filtered water from my refrigerator? No. Standard refrigerator filters do not remove all microorganisms. Only filters with an absolute pore size of 1 micron or smaller are safe for nasal rinsing.
What temperature should the water be? Lukewarm — approximately body temperature (98–100°F). Water that is too hot can burn nasal tissue; water that is too cold can be uncomfortable and may cause a brief headache.
What makes ATO Health Sinus Rinse Packets different? Our packets contain extra baking soda (sodium bicarbonate) in addition to pharmaceutical-grade sodium chloride. This creates a buffered, pH-balanced solution that is more soothing on inflamed nasal tissue and more effective at thinning thick mucus than plain saline alone.
How much water do I use with one packet? One packet is designed for 8 oz (240 mL) of water. For a full neti pot rinse (16 oz), use two packets.
Can I use half a packet? Yes. Half a packet in 4 oz of water creates the same concentration and is appropriate for children or for a quick maintenance rinse.
Do the packets expire? Yes. Check the expiration date on the packaging. Expired packets may have degraded baking soda that is less effective.
Are the packets safe for daily use? Yes. The formula is designed for daily use. Many people rinse once or twice daily during allergy season without any issues.
Can I use the packets with a squeeze bottle instead of a neti pot? Absolutely. The packets work with any nasal irrigation device — neti pots, squeeze bottles, or electric irrigators.
How long does a nasal rinse take? A complete rinse of both nostrils typically takes 3–5 minutes.
How will I know if I'm doing it right? The solution should flow freely through one nostril and exit from the other. If it flows into your mouth, tilt your head slightly more forward. If it does not flow at all, you may be too congested — try a decongestant spray first to open the passages.
Is it normal to feel burning or stinging? Mild stinging is common when you first start rinsing, especially if your nasal passages are very inflamed. Our extra baking soda formula significantly reduces this sensation. If stinging is severe, check that you are using the correct water temperature and that the packet is fully dissolved.
How soon will I feel relief? Most people feel immediate relief after their first rinse. For chronic conditions, consistent daily rinsing over 2–4 weeks produces the most significant improvement.
Can I rinse if I'm very congested? Yes, but it may be more difficult. If your passages are completely blocked, try inhaling steam first to loosen mucus, or use a saline nasal spray to begin opening the passages before attempting a full rinse.
Should I blow my nose before or after rinsing? Gently blow your nose before rinsing to clear the passages as much as possible. After rinsing, gently blow again to clear remaining solution and loosened mucus.
Does nasal rinsing help with pollen allergies? Yes. Rinsing physically removes pollen from your nasal passages before it can trigger a full allergic response. It is most effective when used proactively — rinse after coming indoors on high-pollen days, not just when symptoms are severe.
How often should I rinse during allergy season? Once or twice daily during peak pollen season. Many people find a morning rinse and an evening rinse (after outdoor activities) to be the most effective routine.
Can rinsing replace my allergy medication? For some people with mild to moderate allergies, consistent nasal rinsing significantly reduces or eliminates the need for antihistamines. For others, it works best as a complement to medication. Consult your doctor about adjusting your medication regimen.
Does rinsing help with dust mite allergies? Yes. Dust mites are a common indoor allergen that can trigger year-round symptoms. Regular rinsing removes dust particles and allergens from the nasal passages regardless of the source.

Can I rinse when I have a cold or flu? Yes. Nasal rinsing is particularly beneficial during viral illness. It removes excess mucus and helps clear the nasal passages, reducing congestion and supporting faster recovery.
Does rinsing help with HMPV symptoms? Yes. HMPV (Human Metapneumovirus), which is currently surging in 2026, causes significant nasal congestion. Rinsing 2–3 times daily can provide substantial relief from this symptom.
Can I rinse if I have a sinus headache? Yes. Rinsing can help relieve sinus headaches by reducing the pressure caused by mucus buildup. Use lukewarm water and rinse gently.
Will rinsing spread the illness to my other nostril? No. The solution flows from one nostril to the other in a way that flushes rather than spreads. The direction of flow is designed to clear both sides effectively.
How do I clean my neti pot? After each use, rinse the neti pot with distilled or previously boiled water, then allow it to air dry completely. Do not store it wet. Once a week, wash it with dish soap and hot water, rinse thoroughly, and air dry.
How often should I replace my neti pot? Ceramic and stainless steel neti pots can last for years with proper care. Plastic neti pots should be replaced every 3–6 months or when they show signs of wear, scratching, or discoloration.
Can I share my neti pot with family members? No. Each person should have their own neti pot to prevent cross-contamination.
Can I put my neti pot in the dishwasher? Check the manufacturer's instructions. Many ceramic and stainless steel neti pots are dishwasher safe; plastic ones may warp at high temperatures.
