For severe sinus congestion (lasting more than 3 months in duration), try Flo CRS. It is a large volume nasal and sinus irrigation or wash that has been specifically formulated for sinus congestion.

It is a non-medicated, preservative-free, isotonic irrigation solution that helps clear the nose, sinus cavities and back of the throat by washing away excess mucus and any inflammatory matter they may contain. Flo CRS is gentle enough for daily use too.

Flo CRS helps relieve sinus congestion by washing away mucus, pollens and irritants from the nose and sinus cavities by using a large volume irrigation fluid. Large volumes (up to 70-80mls per nostril) are required to reach and adequately wash the sinus cavities.

Flo CRS consists of a Xylitol formulation that has a very low concentration of salts (sodium and potassium) to help relieve severe sinus congestion.

Use Flo CRS as directed by your health professional.
