First Defense Nasal Screens (FDNS) are non-inserted, self-adhering nasal filters with patented technology. They sit gently on the outside of the nostrils and filter the air you breathe before it enters your body.
About 90% of the air we breathe passes through the nose. FDNS uses a breathable, medical-grade filter media to intercept airborne particles right at the nasal passage, with a filtration efficiency of up to 99% for allergens and other contaminants.
