What Water To Use
Although neti pots are known to be helpful for most individuals, they can cause harm if they are not used and cared for correctly. An individual should never use tap water in their neti pot because it generally contains small quantities of protozoa, amebae, bacteria, and other microorganisms. Tap water is okay to swallow because the digestive acid and enzymes in the stomach can kill these pathogens. If these pathogens enter the nasal passages through a neti pot, the microorganisms will not be eradicated and can colonize in the area.
To ensure no foreign material or microorganisms enter the nasal cavities, an individual should only use certain types of water when they are using their neti pot. Tap water may be used only if it is brought to a boil for a minimum of three to five minutes and then allowed to cool down. Boiled tap water should be stored in a closed container for no more than twenty-four hours when it is intended for use in a Neti pot. Sterile water, distilled water, and water filtered at a minimum pore size of one micron are also safe to use in a neti pot.
