Are children and adults only different in size?
The “civil hygiene mask” group standard covers 13 standard indicators. Specially divided into adult masks and children’s masks, their specifications are also large (L), medium (M), small (S). It is worth noting that it is far more than “size”. This new standard highlights the comfort of civilian masks. The ventilation resistance of adult masks is set to 鈮?9 Pa (Pa). According to the current technical level of domestic mask filter materials, considering the child’s physiological condition and protecting the respiratory system, the ventilation resistance of the child mask is set to be 鈮?0 Pa (Pa).
Experts explain that in fact, the well-known N95 masks and medical protective masks have standard ventilation resistances of about 300 Pa. Although its protective performance is higher, it is not conducive to breathing.
Of course, in terms of the most important functions of masks such as anti-particles, droplets, smog and pollen, the new standard treats adults and children the same, for example, the bacterial filtration efficiency is not less than 95%, and the particulate filtration efficiency is not less than 90%. All bacteria and viruses cannot exist alone, and must be attached to the droplets and particles in the air. Therefore, the particles that can be blocked by the mask must be between PM0.5 and PM1. In addition, according to the relevant provisions of GB18401 “National Textile Product Basic Safety Technical Specifications”, the formaldehyde content of children’s masks is the same as that of adult masks.China Personal Protective Mask factory
