These masks are made in the workshops in Paris where Le Lys matches their unique savoir-faire and high quality materials in order to make them durable, efficient and with a high refinement.
The Le Lys Paris mask owns an excellent filtering medium that filters at least 95% of particulate matter PM2.5 (main responsible for pulmonary diseases), with a level equivalent to the threshold of the European standard NF EN 143. The filtering medium protects against particles and liquids such as dust, smoke, urban fumes.
