GB2626-2006 masks can protect against viruses, and masks that comply with GB2626-2006 are called industrial dust masks. According to the mask guidelines issued by the National Health Commission, masks that implement the GB2626 standard are recommended for use on high-risk personnel, and are more than adequate for ordinary people to use on ordinary occasions. The guidelines also emphasize that particulate protection masks that meet the KN95 and N95 standards or above can be used instead of medical protection masks for high-risk, exposed people. Industrial dust masks and medical protective masks are similar in filtering materials, both of which are added to the masks after the electret process treated with meltblown cloth. The meltblown cloth filters relatively large particles through its fiber structure and small particles such as viruses and bacteria through the electrostatic adsorption ability in the material, so as to achieve the effect of virus protection.
