By opening the nasal passages, Rhinomer by Breathe Right nasal strips improve airflow, providing instant relief from nasal congestion. Rhinomer by Breathe Right nasal strips do not contain medication and are clinically proven to allow 31% more airflow when opening the nasal passages. The Rhinomer by Breathe Right strips are two patented flexible plastic bands. The special adhesive allows the strip to comfortably adjust over the nostril flaps, and their flex action allows the bands to lift the nasal passages open and keep the nasal channels open. Rhinomer by Breathe Right strips can be used day or night for nasal congestion relief due to allergies, colds, snoring, or deviated septum, but should not be used for more than 12 hours a day.
