Developed by a physician, NeilMed Sinus Rinse® washes allergens, irritants, bacteria, viruses, and mucus from the nasal passages and sinuses. Unlike simple saline mists, the Sinus Rinse® system delivers a large volume of saline (8 ounces) to the nasal passages for thorough cleansing. Packets contain pharmaceutical grade sodium chloride and sodium bicarbonate to create a solution simulation the concentration of normal body fluids. Soft squeeze bottle allows easy self-administration under low pressure, and can be sterilized in a microwave oven. This update of an ancient treatment is the #1 physician recommended system of its kind. Bottle is adult size, but safe to use in children at half volume.
