Neil Med Sinus Rinse is a natural way of relieving allergy and sinus symptoms. Allergy and sinus disease cause excessive mucus production in the nasal passages. Nasal irrigation will wash away this excess mucus and allergens such as pollen, dust particles, pollutants and bacteria thereby reducing the inflammation of the nasal membranes. Its patented positive pressure squeeze bottle system is easily controlled by the user allowing for the introduction of the solution into the nasal passages, causing volume irrigation. The user has complete manual control of the pressure and volume of solution as it enters into the nasal passages, allowing for a gentle, soothing and therapeutic experience. The positive pressure flow effectively removes thick mucus, crusts and associated pathogens. The saline formula is preservative free, drug free, isotonic and hypertonic, ph neutral, and doesn\'t cause burning and the delivery system is gentle and easy to use. The Neil Med Sinus Rinse system is the #1 recommended positive pressure system by ENT and Allergy specialists as there is a consensus among many ear, nose and throat specialists across USA, Canada, Australia, New Zealand and UK that positive pressure nasal ittigation systems provide the most relief to users suffering from allergy and sinus disease.
