KN95 Face Mask

Short Description:

KN95 masks are A Chinese replacement for N95 masks, and the US Centers for Disease Control (CDC) said KN95 masks are as effective as N95 and are one of the “appropriate alternatives”, BuzzFeed reported. According to 3M, the world’s largest maker of masks, KN95 is “equivalent” to N95 masks and “can be expected to function very similarly”.

Mask is a kind of hygiene products, generally refers to wear in the mouth and nose to filter the air into the mouth and nose, in order to prevent harmful gases, smells, droplets, viruses and other substances, made of gauze or paper.

Masks have a certain filtering effect on the air entering the lungs. Wearing masks has a very good effect during the epidemic of respiratory infectious diseases and the operation in the polluted environment such as dust.

After exposure to air, KN95 masks can be reused for a limited number of times as long as they are not used during aerosol generation and are not contaminated with patient body fluids, but at the same time increase the risk of surface contamination by pathogens. Currently, OSHA does not have any standards for disinfecting KN95 masks, but NIOSH notes that mask manufacturers may give recommendations for maximum reuse, but in the absence of these recommendations, the recommended maximum number of reuses per mask is limited to five to ensure safety. CDC recommends no reuse in general situations, but in emergency situations, such as when masks are scarce, they can be cleaned and reused . People have been trying to explore the cleaning of masks, but there are also concerns that this may reduce the filtering performance of masks or deform masks . Researchers at Duke University have published a way to clean KN95 masks without damaging them by using vaporized hydrogen peroxide, allowing for a limited number of reuses . The U.S. National Institutes of Health has found three methods of disinfection that allow KN95 masks to be reused a limited number of times: hydrogen peroxide, dry heat at 70 degrees Celsius, and ultraviolet treatment. However, if the KN95 mask is disinfected with alcohol, the charge in the mask will be removed, making the mask unable to absorb particles, so it cannot be disinfected with alcohol. Steam disinfection and boiling water treatment above boiling water, little charge loss, acceptable.
