This is the sinus irrigator recommended by doctors because it delivers a pulsating, moisturizing spray and a pulsating rinse that helps eliminate sinus infections. Engineered in Switzerland and used by pro sports teams and trainers, the irrigator’s oscillating cleansing action pulses 1,200 times per minute to help restore nasal cilia, protect the body against irritants, and clean hard-to-reach areas lesser nasal wash products leave behind—published medical journals report that pulsating irrigation is more effective at removing bacteria than non-pulsating methods. Its 24-oz. BPA-free water reservoir provides 3X the cleaning benefit of lesser models. With adjustable pressure and 360° swivel control for comfort. Comes with four total tips—two irrigator tips (one for pulsating rinse and moisturizing spray) and two throat irrigator tips (pulse/spray)—and 30 packets of saline powder. AC plug.
