Speaking of masks, everyone is familiar with them. The most popular ones recently are N95 masks and KN95 masks. Some friends cannot buy them even if they want to, and they have to make an appointment to buy them in order to barely get them.
From this point of view, N95 masks and KN95 masks are still particularly important in our lives.
What is the difference between these two types of masks? Should we choose N95 masks or KN95 masks ? Let’s take a look at the relevant content.
Everyone knows that wearing a mask when traveling can reduce the chance of being infected with the virus , and it can also protect others, so most people wear masks when going to public places. But masks are particularly popular now, especially those with better protection levels.
People think that a mask with a better protection level can block more viruses, has a higher safety factor, and is more secure to wear.
But most people don’t know the difference between these masks, so what about the N95 masks we choose? Is it better to choose disposable medical masks or KN95 masks?
In fact, the protection levels of N95 masks and KN95 masks are similar, and there are not many differences in their essence. It’s just that N95 masks refer to standard masks certified by the U.S. NIOSH standard, with a filtration efficiency of non-oily particles that can reach 95%.
KN95 masks refer to China’s GB2626 mandatory standard, which can also achieve more than 95% filtration efficiency for some non-oily particles.
In other words, KN95 masks and N95 masks have the same efficiency, and both can filter non-oily particles up to 95%.
Therefore, if you want to protect against viruses, you can choose to use N95 medical masks or KN95 medical masks.
However, the editor here would like to remind everyone that not all N95 masks are medical masks, and some are industrial masks. Industrial masks mainly protect against haze particles, while N95 medical masks mainly protect against viruses bacteria .
Generally speaking, when wearing N95 masks or KN95 masks, it is best to change them every four hours or so to prevent excessive contamination.
But if you are in a pollution-free environment and use N95 masks or KN95 masks, you can also consider replacing them every 24 to 48 hours, which can save masks and avoid waste.
However, if you need to reuse it, you should also pay attention to the storage method. It is best to take off the mask and then dry it for disinfection to prevent the mask from being contaminated by other things.
If the mask is damaged when we use N95 masks or KN95 masks, or its edges do not fit closely with our face, we must replace the mask immediately. Preventing contamination from other dirty things can also effectively prevent virus invasion.
Now it is best for us to wear N95 masks or KN95 masks when we go out. If you cannot buy these two masks, you can also choose to wear medical surgical masks .
Medical surgical masks also have a relatively good filtration level and can filter some bacteria that are invisible to the naked eye.
However, everyone should pay attention when using them. Most of the medical masks are disposable. It is best to throw them away as soon as we use them. That’s it for what
