A measurement of a mask material's resistance to penetration of bacteria, from the inside to the outside of the mask (UNI EN 14683:2019).

Result: 99.89%

Aimed at determining the air permeability of the mask (UNI EN 14683:2019).

Result: 57,8 Pa/cm^2

An assessment of the absence of a population of viable microorganisms on the mask and / or packaging (UNI EN 14683:2019)

Result: 7,3 CFU/g

Detects the resistance of the mask to the penetration of blood splatters or synthetic liquids (UNI EN 14683:2019).

Result: passed

Checks for the absence of negative or unwanted side effects generated by the materials used to build the mask (allergies, redness, irritation, toxicity, etc.) (ISO 10993-1:2018).

Result: passed

A measurement of a mask material's resistance to penetration of bacteria, from the outside to the inside of the mask (UNI EN 14683:2019).

Result: 99.88%

Evaluates the nonviable particle retention or filtration efficiency of masks, usually at sub-micron levels (ASTM F2299 / F2299M).

Result: 99.3% at 0.1 micron

Result: 99.90%

States the difference of the infectivity titer of bacteria found on an antibacterial-treated product compared to an untreated product after inoculation with and contact to bacteria (ISO 20743:2013).

Result: 99.995% and 99.959%

States the difference of the infectivity titer of bacteria found on an antibacterial-treated product compared to an untreated product after inoculation with and contact to bacteria, after materials are aged (ISO 20743:2013)

Result: 99.797% and 99.861%
