1.The primary filter layer
The first layer of our mask filters out larger particles such as dust and PM10. The material is sublimation printed to keep the masks more durable.
Sublimation printing uses digital technology that works with polyester and polymer-coated substrates. The sublimation dyes are transferred via liquid gel ink through piezoelectric print heads to special paper. The dye is then transferred into the fabric with heat and pressure. The end result melts the dye at the molecular level with the textile, which means that it cannot be removed from the wash. If dye is only applied to the surface of the textile or material to be printed, it can be removed from wear or washing, which we avoid with this technique.
2.The three-layer microparticle layer
The second layer of the mask blocks particles like PM2.5. It was tested to filter 94.79% + of the particles as small as PM0.3 that surpass the N90 masks. The textile is a three-layer non-woven polypropylene, a thermoplastic polymer that is used in a number of applications.
The blow molding process begins with the polymer being melted down and formed into a "preform" - a liquid ball. Air is then passed at high speed to weaken the filaments and create a fibrous web. The random fiber orientation that triggers this is advantageous because it creates a better mesh to trap particles. The textile is also made with a large surface area, which means that a larger percentage of the particles are caught when it passes the filter.
3.The internal filter
This pro mask is supplemented by the internal filter, which consists of a 100% pure activated carbon fabric
All activated carbons - traditionally powders and granules - generate “Van der Waal” forces due to their porous structure. These forces give activated carbons their unique potential to adsorb gaseous molecules, including anions and cations, in their inner pores.
