Xlear (pronounced "clear") Sinus Care nasal spray is a non-addictive, all-natural solution that promotes upper respiratory health by cleansing and moisturizing the nasal passages. When used in daily hygiene, the patented solution with xylitol not only hydrates the sinuses and nasal passages, but also washes away airborne contaminants and pollutants. Over 90% of all infection-causing bacteria enter through the nose. Clinical studies have shown that Xlear Sinus Care nasal spray with xylitol, when used regularly, can substantially reduce sinus and upper respiratory infections including otitis media (middle ear infections) by reducing the ability of harmful bacteria, pollens, allergens and other irritants from adhering to nasal tissue. Because Xlear Sinus Care nasal spray is clinically proven to be helpful, ENT doctors, pediatricians, dentists, and other health care professionals in over 20 countries continue recommending it to their patients.
