Scough's secret is its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m2 for trapping sneeze fragments and pollution. The structure of activated carbon creates strong Van Der Waals forces, pulls in pollution, and germs to hold them in their crevices and neutralize them.

How to wear: First, pull the elastic loop over your head and settle it around the base of your neck. The elastic neck strap guarantees easy accurate filter placement so you're always getting a filtered breath. To start filtering, pull the filter over your nose and pinch the embedded nose crimp to set yourself up with the best seal possible.

Our Scough scarves are all hand sewn in our local US factory in Brooklyn, using the finest US-made cotton.

We started Scough six years ago as an investigation into how we might use an incredible technology-industrial-grade woven carbon filters-to help keep families healthy and bring awareness to our world's growing air quality issues.
