Salex SSR is the Only Sinus Rinse in South Africa that offers a unique combination of Saline with a Gentle Surfactant to help clear sinus congestion for immediate relief. The Salex SSR Paediatric Kit is a gentle saline nasal rinse system for children. Salex SSR (Saline Sinus Rinse) offers a 0.72% Isotonic Saline Solution, which is made from Sodium Chloride. It is a high-volume, low-pressure nasal rinse system used in more severe sinus-related cases to “flush” the sinus cavities using a hydro-dynamic force, clearing excess mucus from the nasal passages and sinuses.
