1.Different layers

Medical masks are composed of a mask face and a tension band. The mask face is divided into inner, middle, and outer layers. Ordinary medical masks are common gauze masks. There are four, eight, and sixteen specifications.


2. Different protective effects

Ordinary masks are used to filter the air that enters the nose and mouth to prevent harmful gases, odors, and droplets from entering and exiting the wearer's nose and nose.

Medical masks are comfortable, odorless, glass fiber-free, non-irritating to the skin, waterproof, and can disinfect or remove pathogenic microorganisms on the media after disinfection to make them harmless; and they can be dust-proof because Breathing resistance is small, wearing hygienic, aerosol, dust, fume, mist, poisonous gas and poisonous vapour are adsorbed by the filter material to block and not be inhaled by people, and effectively isolate the source of pollution.


Mask

KN90 masks are the standard for respiratory protective equipment GB2626-2006 promulgated by the National Quality Supervision, Inspection and Quarantine Bureau and the National Standardization Management Committee. Units producing dust masks must obtain a production and operation license in accordance with the law. The production technical specifications of all dust masks must meet the corresponding standard. This standard specifies the production and technical specifications of respiratory protective equipment, and has strict requirements on the material, structure, appearance, performance, filtration efficiency (dust blocking rate), breathing resistance, detection methods, product identification, packaging, etc. of dust masks. The material of the dust mask must be non-irritating and non-allergenic to the skin, and the filter material is not harmful to the human body. The structure of the dust mask must be convenient to use. The dust rate must be greater than 90%, and the dust resistance rate of particle diameters less than 2 microns must be greater than 70%.



Mask

The N95 mask is one of nine particulate protective masks certified by NIOSH (National Institute for Occupational Safety and Health). N95 is not a specific product name. As long as it meets the N95 standard and passes the NIOSH review, it can be called a N95 mask, which can filter particles with an aerodynamic diameter of 0.24 ± 0.6 μm (physical diameter 0.075 μm ± 0.020 μm). More than 95%.

mask

Medical surgical masks are masks worn by medical staff at work. It is mainly used in medical clinics, laboratories, operating rooms and other high-demand medical environments, with a relatively high safety factor and strong resistance to bacteria and viruses. Medical surgical masks can also be used to prevent the spread of influenza and respiratory diseases.
