Xlear's secret is the patented, natural saline spray containing xylitol—an ingredient which cleanses and moisturizes. Normal saline nasal sprays can dry out the nasal passage, actually leaving it more irritated and susceptible to external contaminants. But with the addition of xylitol, Xlear Saline Nasal Spray with xylitol will moisturize and soothe your sinus and nasal passages. Xylitol also has cleansing benefits; it almost acts like soap for your nose. The industry-leading formula alleviates congestion and also prevents bacteria and other pollutants from sticking to nasal tissues. Now you can naturally promote upper respiratory health while alleviating congestion with Xlear Saline Nasal Spray with xylitol!
