xDiscover First Defense Nasal Screens
First Defense Nasal Screens is an innovative, lightweight solution that is worn without insertions or intrusions, and is almost invisible when used. Its soft design adheres to the nasal opening to filter the air we breathe, prioritizing comfort and simplicity in daily life. It is designed for people looking for a simple user experience without sacrificing the filtration of the air they inhale during their usual routines, whether in the city, on public transport, or in indoor spaces.
Certified tests indicate that FDNS can make a significant difference even at submicron levels. Tests report an efficiency of 77% at 0.1 µm, over 92% at 1 µm, and over 99% at 10 µm. These numbers reflect remarkable filtering performance for a lightweight, non-invasive product, designed for an estimated 24 hours of use per set.
