GENERAL NOTES : 1 μm = 1 micrometer representing one millionth of a meter. The diameter of human hair is between 17 μm and 181 μm.

BREATHABILITY: The smaller the numbers in the results, the better the air permeability.

CAUTION: These masks are not respirators. They should not be used in case of: Pulmonary or laryngeal tuberculosis and measles. Washing a disposable surgical mask reduces its filtration efficiency on fine (submicronic) particles by 40 to 70% through the destruction of its electrostatic charge and its protection against fluids. Washing disposable masks releases millions of nano- and microparticles of polymers into the water. Moreover, the chemicals that make these masks resistant to fluids and pathogens can be dangerous to human health and environment.
