Between you and the air.
A self-adhesive nasal filter. Invisible. Drug-free. Lasts all day.

First Defense Nasal Screens are small self-adhesive patches that sit on the outside of each nostril. A spunlaced polyester filter catches dust, pollen, and fine particles before you breathe them in, while staying comfortable enough to forget you're wearing them.
One pair lasts up to 24 hours. Peel, stick, go.

Filter specification
The filter media is non-woven spunlaced polyester. In controlled lab testing by EMSL Analytical in 2018, the media captured:
- more than 99% of particles 10 micrometres and larger
- around 93% of particles under 2 micrometres
- close to 80% of particles below 0.1 micrometres
These figures describe the filter media under lab conditions. Real-world performance depends on fit, how you breathe, and what's in the air.
