Recently, a new type of coronavirus has struck, and experts recommend wearing a mask when going out. Masks are divided into several categories, ordinary masks, surgical masks, KN95 masks, N95 masks, etc. So what is the difference between the most common KN95 masks and N95 masks?


KN95: Chinese norms and standards stipulate that masks can be divided into two categories: KN and KP according to function. KN is suitable for filtering non-oily particulate matter, and KP is suitable for filtering oily particulate matter. The following figure is the percentage of filtration efficiency. KN95 stipulates that the filtration efficiency for non-oily particles above 0.075 microns is greater than 95%.


N95: American NIOSH dust mask standard, detailed parameters are consistent with China KN95. In other words, KN95 and N95 are just different in name, and the masks produced according to these two standards have the same protection level. You can rest assured to buy any KN95 or N95 standard mask, the protection effect is no different, all meet the kn95 mask detection standard.


Some products of KN95 masks have a cold flow exhalation valve. Also according to expert recommendations, this device does not affect the efficiency of virus filtration, and friends can buy it with confidence.


In addition to wearing masks when going out, personal health should also pay attention to. Lemonade and vitamin effervescent tablets can also be prepared. Studies have shown that the lack of vitamins in the body can cause resistance to decline.


The protective effect of these two types of masks is very good, so after wearing this mask, there will be difficulty breathing, so everyone should pay more attention when wearing this mask.


You can rest assured to buy any KN95 or N95 mask, as long as it meets the standard. When we wear the mask, we must master the correct wearing method. Discard the mask after it has been used or after it has been damaged by damp.
