Pollution Protection

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.

 Le Lys Paris Anti pollution Masks

All our masks have removable filters that filters the 2.5 particles.
Clients may order new filters on our website.

Layout of the filter of our masks

The lifetime of the filter depends on:

• The place of exhibition
• The time spent using the mask
• The degree of pollution

Particulate matter (PM) pollution in air affects people's living quality tremendously, and it poses a serious health threat to the public.

The PM is a complex mixture of extremely small particles. Based on the particle size, PM is categorized by PM2.5 and PM10 which refer to particle sizes below 2.5 μm and 10 μm, respectively. PM2.5 pollution is particularly harmful since it can penetrate human bronchi and lungs due to its small size. Hence, long term exposure to PM2.5 increases morbidity and mortality. During hazy days, the visibility decreased a lot and the air quality was unhealthy due to extreme high level of PM2.5.

The PM2.5 pollution particles in air have complicated compositions including inorganic matter (such as SiO2, SO42− and NO3−) and organic matter (such as organic carbon and elemental carbon) from diverse sources including soil dust, vehicular emission, coal combustion, secondary aerosols, industrial emission, and biomass burning.
