FLO CRS is a large volume nasal and sinus wash that has been specifically formulated for patients suffering from sinusitis. FLO CRS is a large-volume, non-medicated, preservative-free, isotonic irrigation solution for severe sinus congestion. It helps to clear the nose and sinus cavities by washing away mucus and inflammatory matter in a natural way.

FLO CRS is formulated with Xylitol and has a very low concentration of salts that ensures it does not adversely affect salt sensitive immune factors in the sinuses.
