Easily Identify The Quality Of Disposable Masks In 5 Steps
1. In a place with sufficient light, place the side close to the face and the light is 180 degrees to see if the non-woven fabric is shiny and free of broken hairs. Masks with stains, broken hairs, and color casts are inferior.
2. Feel the whole mask whether it is soft, smooth and not rough. Mask fabrics that are hard, rough, and thin are inferior products.
3. Smell whether the mask has a peculiar smell, not only the cloth surface, but also the ear straps. Peculiar smell is inferior. (Individual packaging can prevent the mask from being infected by odor, dust, and bacteria in the air.)
4. Wear it to see if the ears are strangled, and if there is irritation on the ears and nose. The ears and peculiar smell are defective products.
5. See if the packaging has a production address and implementation standards, usually GB15979-2002 or corporate standards. If the packaging paper is of poor quality, smells, unstandardized or scribbled, the mask is probably made by a workshop. Note: The GB2626-2006 standard is completely inapplicable.
