The continuous spread of COVID-19 coronavirus has raised our awareness of prevention, and people pay more and more attention to self-protection. So, can face masks prevent COVID-19 coronavirus? What kind of mask can prevent coronavirus? this post will tell you.
Wearing Face Mask Can Prevent COVID-19 Coronavirus in Some Degree
If you are likely to be in close contact with someone infected, a face mask cuts the chance of the disease being passed on. If you’re showing symptoms of coronavirus, or have been diagnosed, wearing a mask can also protect others. So masks are crucial for the health and social care workers looking after patients and are also recommended for family members who need to care for someone who is ill.
General medical-surgical masks and N95 masks can prevent COVID-19 coronavirus.
The medical mask is the operating room, there are body fluids, blood spatter risk environment commonly used medical mask, can block blood, body fluid through the mask to pollute the wearer. At the same time, the filtration efficiency of bacteria is not less than 95%, but the filtration efficiency of particles is limited, and most of them are rectangular design.
The N95 mask can well prevent respiratory tract infection and haze, which is characterized by the prevention of droplet infection caused by patients.
There are two kinds of ordinary N95 masks. Breather valves are thought to reduce protection against viruses, while breaths without valves are less breathable and more laborious to breathe.
NOTE: Although the face mask can prevent COVID-19 coronavirus to a certain extent, it is not 100% preventive.
If you are healthy, you only need to wear a mask if you are taking care of a person with the suspected 2019-nCoV infection.
Wear a mask if you are coughing or sneezing.
Wear a mask if you are going out to crowded public places. Such as stations, shopping malls, supermarkets, subways, buses, etc.
Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water.
If you wear a face mask, then you must know how to use it and dispose of it properly.
At present, COVID-19 coronavirus has gradually broken out all over the world, and the news of necessities shortage can be seen everywhere especially epidemic prevention materials.
Such as face masks, disinfectants, 75% alcohol disinfection wipes and so on. Among them, the surgical face masks can be said to be the most difficult to buy epidemic prevention materials. So where can I buy a surgical face mask for coronavirus COVID-19 that meets the quality standards?
Wearing a face mask can not 100% resist COVID-19 coronavirus. However, face masks are effective at capturing droplets, which is the main transmission route of COVID-19 coronavirus, and some studies have estimated a roughly fivefold protection versus no barrier alone.
At present, protective masks in many places have been sold out, where can buy face masks that meet the 3 layer quality standards? You can buy it at a reasonable price!
All kinds of protective face masks are available on the platform, such as surgical masks, KN95 masks, N95 masks, KF49 masks and disposable PM2.5 masks and so on.
As we all know, the number of cases of COVID-19 is still increasing, wearing a face mask is one of the effective ways to block the spread of the coronavirus, while the N95 mask has the highest level of protection among all masks, and novel coronavirus has the best effect of blocking it.
So do you have to wear an N95 mask to prevent COVID-19?
The N95 mask is the highest protection level of all masks. It is a mask certified by the testing center of the National Institute of Occupational Safety and Health, which can completely block droplets produced by people when talking and sneezing.
It is very helpful in isolating the virus. Therefore, wearing this type of mask is very effective in preventing coronavirus.
However, due to the short supply of face masks on the market, many people are unable to buy N95 masks.
Buying ordinary disposable surgical masks and disposable medical care masks can also have the effect of blocking the spread of the coronavirus.
Coupled with the fact that N95 masks are mainly used for epidemic prevention among front-line health care workers (belonging to high-risk exposed groups), ordinary people should leave the most scarce protective equipment for front-line health care workers, and there is no need to buy N95 masks.
In the face of COVID-19 coronavirus, there is no need to panic, the most important thing is to take precautions.
Do not go to crowded public places, go out to wear masks, wash hands frequently, do a good job of personal hygiene protection. Protecting yourself is the greatest contribution.

With the global outbreak of COVID-19, surgical masks and respirators and other epidemic prevention equipment are in short supply.
As we all know, the N95 mask is the most recommended model among COVID-19 ‘s protective masks. So what’s the difference between N95 and KN95? Can KN95 be used instead of N95?
What is the difference between different models of N95 masks such as N95 1860, N95 9210 and N95 8210? in this post, we’ll give you a detailed introduction about N95 VS KN95 mask.
KN95 masks are actually masks that meet the requirements of China GB2626 standards, and “GB” means China standards. This refers to the filtration efficiency of≥95% for non-oily particles.
The N95 mask refers to the United States NIOSH certification, the standard is also non-oily particulate matter filtration efficiency≥95%.
Therefore, we can clearly understand that the actual effect of N95 and KN95 is the same, the non-oily particle filtration efficiency≥95%, which is very effective for COVID-10 coronavirus protection.
The US Centers for Disease Control (CDC) says KN95 masks are as effective as N95 masks and are one of the many “suitable substitutes” for N95 masks that are “in short supply”. According to 3M, the world’s largest mask maker, the KN95 is “equivalent” to the N95 mask and “can be expected to be very similar in function”.
Therefore, in the case of a shortage of epidemic prevention resources, KN95 can play the same protective role as an N95 mask.
Of course, there are several other mask models in addition to the most suitable N95 and KN95. For example, FFP3, FFP2, KF94, and KN90 masks. So what’s the difference between these masks? Which respirator has the highest level of protection?
In fact, the letters in front of each mask type represent different national standards. The “N” series of the mask is the American NIOSH standard, the “KN” series is the Chinese standard, the “FFP” series is the European standard, and the “KF” series is the Korean standard.
And then, the number after the letter refers to the protection ability, the larger the number, the higher the protection level.
For example, 95 refers to the ability to filter out more than 95% of non-oily particles, so the 90 series is not as protective as 95 but is also resistant to more than 90% of particulates. In the European standard FFP series, “2” basically corresponds to “95”, and “3” is more efficient, up to 99%.
If the number ends with the letter “V”, it indicates that there is a breathing valve on the mask, such as the common N95 8210V mask.
To sum up, if we sort the filtering capabilities, we can simply understand it as:
FFP3 > FFP2=N95=KN95=KF94 > KN90
Above we have mentioned N95 8210V mask, friends who know about face masks must know that in addition to N95 8210V, we also often use N95 9210 mask, N95 1860, N95 8210, and other N95 models in our daily life.
So friends who are not familiar with masks must be confused. What’s the difference between so many models of N95 masks? How to choose? Just read on!
For example, 3M masks, most protective masks are clearly marked on the outside of the mask, which can be used to identify the model of the exit mask, NIOSH certification, and other information.
The most common N95 mask model on the market can filter at least 95% of solid or liquid non-oily particles with a diameter of 0.3 microns or more.
The use of advanced electrostatic medium technology can enhance the ability of particle capture while reducing respiratory resistance so that the wearer can breathe more smoothly.
And the most common one is the N95 8210.
There is also an equivalent economic version of N95-8200, which uses braided headbands that are not easy to pull hair, the N95-8210plus that makes it more comfortable to wear, and the same product N95-8110S, which is more suitable for people with small faces.
The N95 8210V adds a Cool Flow breather valve to 8210 to make it easier to breathe (exhale), keep your face cool and reduce the amount of moisture that accumulates inside the mask.
N95 masks with breathing valves are more comfortable to use in hot and humid conditions and are suitable for situations where you need to wear a mask for a long time.
Although the N95 mask with a breathing valve has the same protective effect and meets the N95 standard, it is not two-way protection.
Sick/potentially sick people wear an N95 mask with a breathing valve, and germs may flow out. N95 masks without breathing valves protect themselves and others, but N95 masks with breathing valves can only protect themselves, not others.
The N95 8511 is the most popular N95 mask with a breather valve on the market.
The breather valve can keep the inside of the mask cool and is more suitable for hot, humid environments or situations that need to be worn for a long time. Braided headband and M-shaped nose clips are used to improve comfort.
In addition to the 8511 based on the addition of veneer cushion design, the soft inner layer adds extra comfort to the N95-8211 mask.
In addition to the “N” series, there are R95 masks and P95 masks. As professional protection products for harsh environments, both R95 and P95 masks can filter oily and non-oily particles.
The “R” series masks are resistant to oil fog, and the “P” series masks are oil resistant and can be used wherever they need to be protected in an oil environment.
R95-8240: economical R95 mask with anti-collapse shell design for increased durability.
R95-8246: contains activated carbon adsorption layer to filter acid gas.
R95-8247: The activated carbon adsorption layer can filter harmful organic vapor.
P95-8271: equipped with breathing valve, M-shaped nose clip and braided headband for added comfort.
P95-8576: P95 mask for acid gas, equipped with breathing valve, M-shaped nose clip and a braided headband, comfortable and durable.
P95-8577: P95 mask that can protect against organic steam, equipped with a breathing valve, M-shaped nose clip, and a braided headband, comfortable and durable.
Medical N95 masks offer more fluid resistance/waterproofing than other industrial N95 masks, protect against splashes and splashes of blood and other infectious liquids, block some airborne biological particles, and comply with CDC’s tuberculosis control guidelines.
FDA approved N95 masks that can be used in surgery.
N95-1860: the most popular medical N95 mask, traditional cup-shaped design.
N95-187+: the folding three-dimensional structure design is adopted to reduce the problem of foggy glasses and make it portable and comfortable.
N95-1804/1805: economical folding medical N95 mask, very portable, 1805 is an old version, is being replaced by 1804, and 1805S and 1804S versions are suitable for people with small faces.
For the protection of bacteria, the protective effect of a medical N95 mask should be the best.
But there is no need for ordinary people to choose this type.
For the prevention of droplets and airborne diseases, medical N95 masks and industrial N95 masks are N95 standards, filtering only 95% of the particles.
And people generally do not encounter the situation of being spattered by a large amount of liquid, which is different from the situation in which doctors are likely to produce a large amount of blood and body fluid spatter due to the use of electric medical devices during surgery.
If you want the best protection, wouldn’t it be more realistic to choose an industrial N100 mask or a P100 mask that can filter 99.97% particles?
However, it is hard to breathe after wearing the N95 mask, and the permeability of the N100 and P100 should be even worse. Friends are advised to consider carefully.
Here, I believe that everyone has a deep understanding of N95 and KN95 masks.
Although the national standards of each mask are different, the actual protective effects are similar. There is no argument that N95 is valid or KN95 is invalid.
What is more, it is hoped that the COVID-19 coronavirus can be controlled as soon as possible and stay away from wearing masks.
