PATENTED SPIDERWEB NANO BIOTECH FILTER
Tested by DGA Direction Générale de l'Armement, TÜV SUD & INTERTEK
A spider-web-like microstructure with hundreds of millions of micropores per square centimeter.
The biotech filter consists of three categories: Depth that filtrates ≥ 99 % of particles, Surface that filtrates 99.99% of particles and lastly Screen. The screen is like a sieve and is 100% effective in retaining particles larger than the filter’s pore size.
The microporous COSMO+ MASK can filtrate all particles larger than 0.3 μm diameter. The coronavirus is <0.1 μm diameter and mainly transmits through droplets and aerosols, which are generally greater than 5 μm and 1 μm diameter.
As a result, the microporous filter-film mask blocks out the coronavirus main method of transmission.
