Quick answerA neti pot is a small spouted container for rinsing your nasal passages with saline. The FDA says sinus rinsing can remove dust, pollen and other debris and help loosen thick mucus. The most important rule is the water: use only distilled, sterile or previously boiled water, never straight from the tap. The CDC warns that, although rare, people have died from rinsing their sinuses with tap water containing Naegleria fowleri or Acanthamoeba. Wash and dry the pot between uses, and see a provider if symptoms worsen.

What a neti pot does

The FDA lists neti pots among nasal irrigation devices, alongside bulb syringes, squeeze bottles and battery-operated pulsed water devices. It says sinus rinsing can remove dust, pollen and other debris, help loosen thick mucus, and moisten nasal passages exposed to dry indoor air.

NeilMed lists uses for its NasaFlo neti pot including nasal allergies, dryness and hay fever, sinus pressure and stuffiness, and nasal symptoms from colds, flu and sinusitis. For sprays and other formats, see our saline nasal spray guide.

The CDC explains that germs such as the amebas Naegleria fowleri and Acanthamoeba can grow in public and private water tanks and pipes, and that if they go up the nose to the brain they can cause nearly always fatal infections. The FDA says boiled water can be kept in a clean, closed container for up to 24 hours.

How to use a neti pot

The FDA's steps are:

Saline packets and pot materials

NeilMed's NasaFlo neti pots come with premixed packets of USP grade sodium chloride and sodium bicarbonate, which it describes as pH balanced and isotonic, and preservative and iodine free. It sells a clear neti pot with 60 packets and a blue porcelain pot with 50 packets, and says the pots are suitable for use after sinus surgery and during pregnancy.

Premixed packets save measuring, but they do not change the water rule: mix them only with distilled, sterile or properly boiled water.

NeilMed describes its packets as made from USP grade salts with a purity level of 99% or higher, and its kits as free of preservatives, drugs, iodine, BPA, gluten and latex. Each kit includes an educational brochure with directions in English, Spanish and French, so read them before your first rinse.

Children and when to see a doctor

The FDA says to make sure the device fits the age of the person using it, and notes that very young children might not tolerate the procedure. Ask your child's pediatrician first.

If symptoms are not relieved or get worse after nasal rinsing, the FDA says to return to your health care provider, especially if you have fever, nosebleeds or headaches while using the rinse. Health care professionals and patients can report problems with nasal rinsing devices to the FDA.
