It is safe, has no side effects, and can be used long-term. Currently, nasal irrigation devices include tubular nasal irrigators and yoga neti pots. Tubular nasal irrigators require repeated squeezing and relaxing, causing the rinsed liquid to flow back into the rubber bulb, creating contamination and health risks. Furthermore, operation is extremely inconvenient. Yoga neti pots utilize a curved diversion tube, allowing the rinse liquid to flow naturally, making nasal irrigating more difficult.
