The filtration of your WAIR scarf is really effective.
Sealing is ensured by the rigid structure, with the morphological outline. Filtration is ensured by WAIR filters.
They are composed of activated carbon and polypropylene, which are active materials. The physical properties of each of these materials allow filtering of fine particles present in air pollution such as PM10, PM2.5 and PM0.1.
The WAIR filters therefore stop 90% of the pollution to a minimum, and offer you excellent breathability for cycling in the city.
The active materials used see their efficiency curve decrease after one month. That's why we encourage you to change them every month, to maintain the promised level of efficiency. Whether you have used it every day, or not.
The SUPAIRMAN by WAIR app is also available for free on IOS and Android to inform you about air quality around you !
