Kit includes nasal irrigator, storage sleeve, 50 pre-mixed saline packets, mixing cup and instructions. Syringe delivery system allows user to controls the flow and pressure of the saline solution for optimum comfort and effectiveness. Patented technology with silicone tip/applicator to allow for an easy and gentle rinsing experience. Designed to protect against backflow to avoid the possibility of reinfections if user stops or slows down during the rinsing process. Anyone 2 years or older can use Nasaline. However, children ages 2-12 should not use Nasaline, without parental supervision, unless advised otherwise by your child’s doctor. We suggest Nasaline Junior, a smaller nasal rinsing unit, for ages 2-12, also used with parental supervision. We recommend the NeilMed Baby NäsaKleen Nasal Aspirator for newborns and toddlers.
