Q: What is the advantage of NasalCare?

A: The patented, unique nasal rinse device is composed of a bottle pump with a pair of one-way air valve and one-way liquid valve. The one-way liquid valve permits the fluid to flow only from the liquid transfer tube into the nostril but not back to the bottle, therefore, preventing the solution in the bottle from contamination. The one-way air valve allows air to flow into the bottle to prevent negative pressure in the bottle. This technology allows continue nasal irrigation, a key factor to deliver the solution into sinus. The flow speed of the liquid is easily controlled by the user's hand.
