The Nasopure Effect

You might notice that Nasopure strongly encourages new users to carefully read and follow the instructions on nasal washing. This is because we want you to have a satisfying experience. However, there is also a technique to using the Nasopure bottle, a technique backed by scientific principles.

Some wash systems claim to wash out your sinuses, but the Nasopure system washes your nose, and in doing so, encourages your sinuses to drain naturally. This is called the “Nasopure Effect.” Successfully washing the nose — clearing the tiny cilia so they can move effectively again — and using a law of physics called Bernoulli’s Principle creates the best, the safest and the most complete daily wash possible.

Have you ever noticed how a swiftly moving river draws slower streams into its flow? This is Bernoulli’s Principle in action. Bernoulli noticed that as fluid flows more quickly through narrow areas, the pressure within the fluid actually decreases. The faster the flow, the lower the pressure is within that flow. And other connecting areas of fluid are attracted to low-pressure areas. This is why we see small streams pulled into the swiftly moving flow of large rivers.

Imagine your nose, with Nasopure flowing through, is the river you create each time you wash. Your sinuses are stagnant ponds with small outlets allowing them to drain into the nose. When the saline solution flows past these outlets it creates a low-pressure stream that draws out the contents of the sinus cavities; just like a swiftly moving river would drain a small pond. The best part of Nasopure is, YOU control the speed of flow. So, you control the pressure differential. When sinuses and ears are inflamed, you may want to squeeze gently on your Nasopure bottle so you don’t irritate tender tissues. Other times, you may want to create a rapidly moving stream of saline that is more aggressive in drawing out the sinuses’ contents, keeping them open and less likely to become infected. You have control.

For Bernoulli’s Principle to work at cleaning out your nose and sinuses, you need to direct the flow of solution across the floor of the nasal cavity so it can flow past the sinus openings, creating the pressure differential that drains the sinus contents. If you shoot your solution up, instead of back, you may be aiming directly at the openings to the sinuses and the ears. This is like diverting your river directly into the pond’s outlet, a situation that not only blocks the outward flow, but also can cause transient discomfort as pressure is forced into tiny spaces. This is exactly why we have designed the Nasopure bottle to encourage flow in the most effective direction.

We don’t expect everyone to know about Bernoulli and his principle, but we want you to benefit from the science that stands behind the unique design of the Nasopure bottle. So read the instructions, practice your technique, and visualize a swiftly moving river of pure saline flowing past the sinus ponds drawing out their contents and releasing them as the river flows along the floor of the nose. Finally, take a deep breath and enjoy the sensation of a clear nose and open sinuses. So good!

Thank you Mr. Bernoulli.
