Kf94 mask what do you mean KF94 masks are manufactured under the standards set by the food and drug administration of the republic of Korea. KF94 refers to a type of mask whose filtration rate of particles with an erage diameter of 0.4 meters is greater than 94%. At present, all the protective masks and disposable masks in China he been sold out, and the popular N95 and KN95 masks he also been sold out. So, people went after the KF94 mask. N95 masks are masks with a diameter of 0.3 meters, which filter more than 95 percent of non-oily particulate matter. These masks are made under American standards. Compared with N95 masks, KF94 has a slightly lower filter diameter and filtration rate. However, the standard of KF94 can still filter out the virus brought by droplets in the air, which can play a role in preventing the novel viral pneumonia. Although the standard of KF94 is slightly lower than that of N95, it can also play a protective role, and the price of KF94 is lower than that of N95. Automatic folding one mask machine, the product is used in the production of fold masks production line fully automatic machine, using ultrasonic technology, will be 3 ~ 5 layers of PP nonwoven fabric and melt-blown fabric, activated carbon and filtration material welding, non-woven welding, ear with welding, folded in half, sealing side, slitting the integration of automatic production line for fold masks, N95, KF94 (not Korea KF94 fish this) and other fold masks. As with the N95 structure, the aluminum frame and sheet metal doors are self-improved, with labeling and offset mechanisms removed. Depending on the raw materials used, the masks produced can meet different standards such as FFP1, FFP2, N95, etc. No manual operation is required during the whole process. All masks are manufactured by mechanization. The drawings are for reference only How often a KF94 mask is changed depends on the situation and cannot be generalized. Its use time is related to the environment used, different particle concentration, nature, storage mode, personal habits and other factors. First look at what is KF94 masks, various countries and regions he different masks for each index by the standard of data, usually N/R/P series is American standard, KN/KP series is the Chinese standard (GB2626), FFP series is the European standard, and KF is the Korean Filter shorthand, KF series standard is by the south Korean food and drug administration issued the south Korean mainstream standard masks. KF series is divided into KF80, KF94 and KF99. Among them, the filtration efficiency of KF94 mask is 94%, which means that 94% particles with a diameter of 0.4 meters can be filtered out at least, and both oil and non-oil particles can reach the same level. Non-oil particles include dust, lacquer and microorganisms. Therefore, this mask has a certain isolation effect on the virus. In theory, KF94 masks can be reused. If you are worried about the safety, you can choose to discard them after using them once. If the user is polluting the environment for a long time, it is better to change every 8 hours. We remind you that if the KF94 mask is damaged, contaminated or the wearer feels increased respiratory resistance, it should be replaced in time. In addition, the filtration diameter and filtration efficiency of N95 masks are better than that of KF94. Therefore, it is currently clinically recommended that the public use N95 masks in the prevention of covid-19. What is the correct way to use kf94 mask? Below small make up to explain in detail. Step reading 1 Wash your hands before using If you want to wear a kf94 mask properly, you should first wash your hands, use soap, and use running water to wash your hands. Only after you wash your hands can you be sanitary. Only after that can you wear a mask. Step reading 2 Recognition of location The mask is a little protruding, protruding towards the outside of the face, the front is dark, the reverse is light, the metal strip is above, this position should be recognized. Step 3 read A rope was tied round the ear Then unfold the mask and put a piece of rope over your ears. When you do this, your hands should not touch the inside of the mask. This should be paid special attention to oid contaminating the mask. Step reading 4 Another piece of string was tied around the other ear Then put another piece of rope around the other ear and stretch the mask properly. Do not deform the mask. If it deforms, the mask will not be able to play a protective role. Step reading 5 Press the metal strip properly
