You don’t need to buy a commercial neti pot to rinse your sinuses. A few common household items can work as a delivery device, and the saline solution itself takes about two minutes to mix. The key to doing this safely isn’t the container you use. It’s the water you put in it.
Choose a Safe Container
A neti pot is just a vessel that lets you pour or push saltwater into one nostril so it flows out the other. Several household items can do the job. A soft rubber ear bulb syringe, an infant nasal bulb, or a clean plastic squeeze bottle (like a travel or sports bottle with a narrow spout) all work well. Some people use a small, clean teapot with a narrow spout that fits comfortably against the nostril opening.
Whatever you choose, make sure it’s made of food-safe material, has no cracks or residue, and can be thoroughly cleaned after each use. Avoid anything with internal parts you can’t reach to scrub, since trapped moisture breeds bacteria. A simple squeeze bottle is the most popular DIY option because it gives you control over the flow and is easy to clean and replace.
Prepare the Water First
This is the most important step, and the one most people skip. Never use tap water straight from the faucet. Tap water can harbor a rare but deadly amoeba called Naegleria fowleri, which causes a fatal brain infection when it enters through the nose. In 2024, a 71-year-old woman in Texas died eight days after rinsing her sinuses with untreated tap water from a recreational vehicle. Cases like this are rare, but they are almost always fatal, which is why every major health agency stresses safe water preparation.
You have three options for safe water:
- Boiled tap water: Bring water to a rolling boil for at least 1 minute (3 minutes if you live above 6,500 feet elevation). Let it cool to lukewarm before use. If your tap water looks cloudy, filter it through a coffee filter or clean cloth before boiling.
- Distilled water: Sold by the gallon at most grocery stores. Ready to use as-is.
- Filtered water: Passed through a filter specifically labeled to trap organisms (look for filters rated at 1 micron or smaller with an NSF rating).
If you boil a batch ahead of time, store it in a clean, tightly sealed container and use it within 24 hours.
Mix the Saline Solution
Plain water in your sinuses stings. A saline solution that matches your body’s salt concentration feels comfortable and helps thin mucus. Here’s the recipe:
- For a full quart (4 cups): Add 2 level teaspoons of non-iodized salt to 1 quart of prepared water. You can increase this up to 3 teaspoons if you find the lower amount doesn’t relieve congestion well enough.
- For a single cup (8 ounces): Use roughly ½ teaspoon of non-iodized salt.
- Optional: Add 1 level teaspoon of baking soda (pure bicarbonate) per quart. This buffers the solution and makes it less likely to cause a burning sensation.
Use non-iodized salt only. Pickling salt, canning salt, or kosher salt without additives all work. Regular iodized table salt contains anti-caking agents and iodine that can irritate your nasal lining. Stir or shake until the salt dissolves completely. The solution should be lukewarm, close to body temperature. Too cold and it’s uncomfortable; too hot and you risk burning delicate tissue.
How to Rinse Your Sinuses
Stand over a sink or in the shower. Tilt your head about 45 degrees to one side so your left ear points toward the ceiling (if you’re starting with the right nostril). Place the spout of your container gently against your upper nostril, forming a loose seal. Breathe through your mouth the entire time.
Slowly pour or squeeze the saline into your upper nostril. Gravity and the gentle pressure will carry the solution through your nasal passages, and it will drain out the lower nostril into the sink. Use about half the solution (roughly 4 ounces per side), then switch sides by tilting your head the opposite direction and repeating through the other nostril.
After finishing both sides, gently blow your nose to clear any remaining solution. Some water may trickle out over the next few minutes, especially if you lean forward. This is normal. Avoid blowing forcefully, since that can push fluid toward your ears and cause pressure or discomfort.
Holding Your Breath Matters
One detail that makes a real difference: hold your breath or breathe only through your mouth during the rinse. This closes off the back of your throat (a reflex called velopharyngeal closure), which prevents saline from running down your throat and helps the solution reach deeper into your sinus cavities. If you find yourself gagging or swallowing saltwater, you’re likely breathing through your nose or tilting your head too far back. Keep your chin slightly tucked and angled downward.
When to Skip Nasal Rinsing
Nasal irrigation works well for allergies, colds, and post-surgical recovery, but there are times to hold off. If one or both nostrils are completely blocked, forcing fluid in can push it toward the ear canal and cause pain or infection. If you’re experiencing ear fullness, an active ear infection, or frequent nosebleeds, rinsing can make things worse. And if the saline burns or stings every time despite adjusting the salt level down, your nasal lining may be too inflamed or damaged for irrigation right now.
Clean Your Device After Every Use
Rinse the container thoroughly with safe water (distilled or boiled) after each session. Wash it with soap and water, then let it air dry completely. A damp neti pot sitting on your bathroom counter is an ideal breeding ground for bacteria and mold. If you’re using a squeeze bottle, replace it every few months since plastic develops micro-scratches over time that harbor germs. Bulb syringes are especially hard to dry internally, so squeeze out all water and store them tip-down.
Never share your irrigation device with anyone else, even family members. And never refill the container with leftover solution from a previous session. Mix a fresh batch each time.
