Using a neti pot is straightforward: you fill it with saline solution, tilt your head over a sink, and pour the liquid into one nostril so it flows through your nasal passages and out the other side. The whole process takes about two minutes once you get the hang of it. The key details that matter are getting the water safety right, mixing the correct salt ratio, and positioning your head so the rinse flows smoothly without draining into your throat.
Why Saline Rinsing Works
Saline irrigation does more than just flush out mucus mechanically. The salt water thins thick mucus and helps the tiny hair-like structures lining your nasal passages (called cilia) beat more effectively, which is your body’s built-in system for clearing irritants, allergens, and bacteria. The gentle pressure of the flowing water also stimulates your nasal lining to release fresh, thinner mucus and increase fluid secretion, essentially resetting your sinuses.
This makes neti pots useful for congestion from colds, chronic sinus problems, seasonal allergies, and post-nasal drip. Many people also use them preventively to keep their nasal passages clear during allergy season.
Start With Safe Water
This is the single most important step. Never use plain tap water in a neti pot. Tap water can contain low levels of bacteria and amoebas that are harmless if swallowed (stomach acid kills them) but potentially dangerous when introduced directly into nasal passages. The CDC recommends three safe options:
- Store-bought distilled or sterile water. Look for those exact words on the label. This is the easiest option.
- Boiled tap water. Bring water to a rolling boil for 1 minute (3 minutes if you live above 6,500 feet elevation), then let it cool to lukewarm. You can store unused boiled water in a clean, sealed container for up to 24 hours.
- Filtered water. Use a filter specifically designed to trap infectious organisms. Not all household filters qualify, so check the CDC’s guidance on which filter types are appropriate.
If none of those options are available, you can disinfect water with unscented household bleach. For a quart of water, add 4 to 5 drops of bleach (depending on the concentration listed on your bleach bottle), stir, and let it sit for at least 30 minutes before use. Double the bleach if the water is cloudy or very cold.
How to Mix the Saline Solution
A standard isotonic saline solution matches your body’s natural salt concentration at 0.9%, which means roughly 9 grams of salt per liter of water. In practical terms, that’s about half a teaspoon of non-iodized salt per cup (8 ounces) of water. Use pure salt without additives: pickling salt, canning salt, or pre-measured saline packets sold alongside neti pots all work well.
Getting the ratio right matters for comfort. Too little salt and the water will sting. Too much and it will burn and feel drying. If you want a slightly stronger rinse for thick congestion, a hypertonic solution (closer to 3% salt) can draw extra moisture out of swollen nasal tissue and help loosen stubborn mucus. But isotonic is the standard starting point and what most people use daily.
The water should be lukewarm, close to body temperature. Cold water is uncomfortable and can cause a brief headache. Hot water will burn the delicate tissue inside your nose.
Step-by-Step Technique
Fill your neti pot with the prepared saline solution. Stand at a sink and lean forward so your face is over the basin. Tilt your head to one side, angling it slightly downward. Your forehead and chin should be roughly level, not tipped back.
Place the spout of the neti pot snugly into your upper nostril, creating a gentle seal. Breathe through your mouth (this is important, as it closes off the back of your throat and prevents water from draining down it). Slowly pour the solution into the upper nostril. Gravity does the work. The saline will travel through your nasal cavity and flow out of the lower nostril into the sink.
Use about half the pot on one side. When you’re done, gently blow your nose over the sink to clear any remaining liquid. Then tilt your head the other way and repeat on the second nostril with the remaining solution.
Getting the Head Position Right
The most common mistake is not tilting your head far enough to the side, which causes the water to run down the back of your throat instead of out the opposite nostril. If that happens, lean forward more and increase the sideways tilt. You want your ear on the lower side to be pointing roughly toward the sink. It feels awkward at first, but after a few tries, the angle becomes second nature.
If water goes into your ears or you feel ear pressure, you’re likely blowing your nose too forcefully afterward or tilting your head back during the rinse. Keep your head forward and down throughout, and blow gently when you’re finished. Some people find it helpful to make a “K” sound right after finishing, which helps clear residual water from the back of the nasal passages.
How Often to Rinse
When you’re actively congested from a cold, sinus infection, or allergy flare, rinsing each nostril once or twice a day is standard. Stanford Medicine’s sinus guidelines recommend twice daily, and note that more frequent rinsing is also fine during symptomatic periods. Most people notice relief within the first couple of uses.
For prevention, many people rinse a few times per week during allergy season or whenever they’ve been exposed to dust, smoke, or dry air. Daily rinsing as a long-term habit is considered safe as long as you’re using properly prepared water and keeping your equipment clean.
Cleaning Your Neti Pot
After every use, rinse the neti pot thoroughly with safe water (distilled, sterile, or previously boiled) and let it air dry completely. Never leave standing water in the pot between uses. A damp pot sitting on a bathroom counter is exactly the environment where bacteria and mold thrive.
Ceramic neti pots can be washed with hot water and a small amount of dish soap, then air dried upside down. Plastic squeeze bottles should be disassembled and dried with all caps and tubes separated. Replace plastic bottles every few months, as they’re harder to fully dry and more prone to harboring buildup in small crevices. If your ceramic pot develops cracks or staining that won’t wash out, replace it.
When It Doesn’t Go Smoothly
If the water won’t flow through at all, your nasal passages may be too swollen. Try using a decongestant spray about 10 minutes before rinsing to open things up, or switch to a hypertonic solution, which can help reduce swelling. Don’t force the water by squeezing harder or increasing pressure, as this can push fluid toward your ears.
A mild burning sensation usually means the salt ratio is off. Remix your solution, measuring carefully. Some people also react to additives in table salt, so switching to pure, non-iodized salt often solves the problem. A small amount of baking soda (a quarter teaspoon per cup) can buffer the solution and make it gentler.
If you notice persistent ear fullness, pain, or nosebleeds after rinsing, stop and give your nasal passages a break for a few days. Nosebleeds can happen in very dry environments where the nasal lining is already fragile. Adding a thin layer of saline nasal gel after rinsing can help protect the tissue in those cases.
