No. First Defense Nasal Screens sit discreetly over your nostrils and are virtually invisible to everyone around you. Most users say their friends and family don't even notice them until they point them out.
Sizes are based on the width of your nostril opening. Size S fits 14-15mm, Size M fits 16-17mm, and Size L fits 18-19mm. If you're unsure, most adults find that Medium is the right fit. You can measure using a ruler or the width of your fingertip as a rough guide.
Each pair is designed for a full day of use. One pack contains 7 individually sealed sets, giving you a full week of protection. Replace them daily for the best filtration performance.

First Defense Nasal Screens block up to 99% of airborne particles including pollen, dust, bacteria, pet dander, mould spores, and pollutants. They've been clinically studied by the University of Florida's College of Medicine.
