Mechanism of action
Flushing the nasal cavity can soothe inflamed tissue and remove irritants like allergens; it may help clear mucus.[
Typical use involves the pouring or pumping of saline water through one nostril and letting it drain from the other.

The water should not be tap water, which may contain small amounts of bacteria that are safe to drink but may be dangerous in the nose. The water should be sterile or filtered for micro-organisms; if tap water is used it should be boiled and cooled.[ ]Saline solution

has a fact sheet recommending one of four methods to make the water safe:
# Boil: Use water that has been previously boiled for 1 minute and left to cool. At elevations above 6,500 feet, boil for 3 minutes.
# Filter: Use a filter designed to remove some water-loving germs. The label may read "NSF 53" or "NSF 58". Filter labels that read "absolute pore size of 1 micron or smaller" are also effective.
# Buy: Use water with a label specifying that it contains distilled or sterile water.
# Disinfect: Learn how to disinfect your water to ensure it is safe from Naegleria. Chlorine bleach used at the right level and time will work as a disinfectant against this germ.

Devices
Neti pots are commonly used and rely on gravity and head position in order to rinse the outer sinus cavities. Typically they have a spout attached near the bottom, sometimes with a handle on the opposite side.[
Various squeeze bottles for nasal irrigation have also been used to apply the water.][
Bulb syringes are commonly used for infants and children.][
There are also irrigation machines available that utilize electric motor-driven pumps.][

. It was customary to perform jala-neti daily, as part of ''soucha'' (personal hygiene according to scriptures). '' Jala neti'', which means to cleanse the nose with water, is an old yogic technique from India. The container used to administer the saline is called a "neti pot". This process removes mucus and dirt and clears the nose. A second neti technique known as '' sutra neti'' uses a piece of string instead of water.
