The development of new crown pneumonia in the United States
The WHO determined that the new variant virus OMIRON of the COVID-19 on November 26, 2021 was determined that the variant of the new variant virus OMIRON, because it has super strong communication capabilities, stronger than Delta variant strains, and it causes the human body to cause the human body.The risk of infection or breakthrough infection has also increased to a certain extent.
When Omiron entered the United States, it quickly became one of the most important COVID-19 viruses in the United States, allowing the number of daily diagnostic people in the United States in January to refresh historical peak data.1,353,675 people.
It can be seen from the community infection distribution map below that almost the United States has become a highly disseminated area.
Although OMIRON is infected, the severe conditions and deaths are not as high as the first few variants, but the CDC still calls on the masses to put on a mask on various occasions, especially those over 2 years old.To ensure the correct way of wearing the mask to effectively intercept the virus.At the same time in the crowd dense places, it should be brought with a better high-quality mask with better filtration effect【source】Essence
What is the ASTM mask standard?
In the past two years, the medical surgical mask (Sugical Mask) is one of the most useful masks in the mass group, because it is relatively cheap, but it can also achieve very good protection effects, and the wearing feeling of medical surgical masks is comparedN95 and other masks are more comfortable.
Medical surgical masks were often used in medical environments such as surgery and dental.The purpose was to help doctors avoid contact with various liquids such as blood, saliva, gas solids, and some other medical reagents during the medical operation.The medical surgical mask belongs to the ASTM Level 3 -level mask.Below, let’s introduce the ASTM mask level.
The level standards for this type of mask are formulated by the American Materials and Testing and Materials (ASTM), which is divided into three levels: Level 1, Level 2, Level 3.
There are five major elements in grading standards: BEF (bacterial filtration efficiency), PEF (particle filtration efficiency), runny nose resistance, Delta P pressure difference, and flame spread.Among them, BEF value and PEF value are the main data basis for people to provide people with safe protection in the COVID-19 environment:
ASTM mask level | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
BEF-bacterial particles in 3.0 microns | ≥95% | ≥98% | ≥98% |
PEF-micro filter diameter is 0.1 microns | ≥95% | ≥98% | ≥98% |
Mask characteristic | Lower protection capabilities Used for the most common medical procedures or only as respiratory etiquette | Have good protection More breathable than Level 3 | Have better protection capabilities |
Except for the protection level, all medical surgical masks have adjusted bands and adjustable ear bands at the bridge of the nose to help ensure that the mask is closely fitted with the face when wearing.
It can be seen from the second that Level 3 -level medical surgical mask can effectively play a filtering role in a person who is not particularly dense in personnel and helps people protect themselves.
Which masks can have anti-virus effects?
At present, there are four main specifications of the most common personal protective masks in the market.
Among these masks, only Medical surgical mask and N95 mask Can play the effect of anti-virus.
- N95 mask
- KN95 mask
- KF94 mask
- Medical surgical mask
Among them, the N95 mask has the best protection effect, but the N95 mask is generally thick and blocks air circulation, but it is not suitable for children.The main reason is that the mask cannot fit the child’s face shape well.At the same time, because the sealing degree is too good, people with insufficient cardiopulmonary function may not be suitable.KN95 and KF94 masks are the standards that meet the standards of China and South Korea, similar to the N95, and the protection effect is very good.Medical surgical masks are relatively thin and comfortable, but the protection effect is not good at N95 masks;
Anti-virus mask type | N95 mask | KN95 mask | KF94 mask | Medical Surgery Mask (ASTM 3) |
|---|---|---|---|---|
Filtering efficiency-pair of granules of 0.3 microns | ≥95% | ≥95% | ≥94% | ≥98% |
Sense | The mask texture is hard Follow-up with the face Breathing feels slightly boring | The mask texture is hard Follow-up with the face Breathing feels slightly boring | The mask texture is hard and soft Follow-up with the face Breathing feels slightly boring | The mask texture is soft It is not close to the face that is close to the face Breathing is more comfortable |

N95 mask
The N95 mask is a protective mask manufactured according to US standards, and the strict inspection and certification procedure of the National Institute of Vocational Safety and Health, which is affiliated to CDC -National Institute for Occupational Safature and Health (Niosh) can be marked as the N95 mask.The N95 mask interception rate of 0.3 microns is more than 95%, which has excellent interception capacity for viruses and bacteria.
- The English name of the N95 mask is N95 Respirator Face Mask.
- N95 is a type of formal in the United States Small particle filtration standard The letter “N” expresses non-oily particles.The number “95” refers to the filtering effect of non-oily small particles of more than 95%.
- N95 masks are not specifically referring to which kind of mask.Any mask that meets the N95 standard can be called the N95 mask.
The N95 mask is shown below:
Tips: N95 mask is divided into Pyrite and Without breathing valve Essence
The US FDA recommends several masks for the public::
3M ™ PARTICULATE Respirator 8670F
3M ™ PARTICULATE Respirator 8612F
Pasture TM F550G Respirator
Pasture TM A520G Respirator
These devices are labeled “Not for Occupational Use.”
FDA main station
Whether the interception ability of the N95 mask depends on whether it is properly worn, and requires a close fit between the mask and the face without gaps.It will definitely play a very effective protection purpose.
The single price of the N95 mask is slightly higher, and there will be occasional counterfeit brands on the market.Users can buy the N95 mask brand approved by CDC 【source】 Essence
KN95
KN95 is a protective mask manufactured based on China, and the interception rate of 0.3 microns is also 95%.With the shortage of epidemic prevention materials, some KN95 masks are approved by the FDA to sell in the US market【source】As a replacement mask for N95.After Omitron appeared and caused an explosive growth of the infection, CDC also authorized KN95 to become a suitable alternative to N95【source】Essence
The KN95 mask is slightly different from the N95.The standards that follow are different.The N95 follows the Niosh standard of the United States, while the KN95 follows the Chinese standard.KN95 is usually used in the same material as N95, which is stiff compared to medical surgical masks.
The KN95 is mainly based on the design of the design.It is easy to store after taking off the mask.The overall curvature of the mask is more suitable for the face curve of the human body.With the ear hanging method, it makes the mask wear more convenient.
At present, there are a variety of KN95 masks on the market.The outer layer is made of non-woven fabrics made of safe color material.The inner layer is soft white non-woven fabric to ensure the safety of the mask and increase the sense of fashion.Or the mood of the wearer adds the fun of wearing a mask in the epidemic.
What is the difference between KN95 and N95 masks?
KN95 mask and N95 mask difference The KN95 mask follows the Chinese standard GB 2626-2006; and N95 meets the standards of the National Vocational Safety and Health Research Institute (Niosh).Both standards stipulate that under the prescribed detection conditions, the filtering efficiency of the mask reaches 95%.
FDA began to allow the United States to import and use the KN95 mask exported by China on April 3, 2020 (New York Times) EssenceThe US CDC also listed KN95 as a substitute in the case of N95.
KF94
KF94 is a protective mask manufactured based on Korean standards.The interception rate of 0.3 micron particles is More than 94% Although lower than 95%, it can be basically met for the protection needs in daily life.
Most of the KF94 masks are composed of non-woven fabrics of 3 to 4 layers.The material is softer than N95 and better breathability.
The appearance design is characterized by the above and lower layers.The three-layer segmented design is used.The upper and lower distance between the middle layer is large, so the breathing area in the front of the oral cavity is large.
The KF94 mask is almost all-in -ear design, which is more convenient to wear and is more suitable for daily life.
Another major feature of KF94 is that the appearance has more fashion, and usually adds some pattern printing to increase its appearance.To identify whether it is a real KF94 mask, you need to see it on the packaging as: Made in KOREA.
Medical surgical mask
Medical surgical masks are generally used in high-demand environments such as medical clinics, laboratories, and operating rooms to wear for medical staff when working.The safety factor is relatively high, and the resistance to bacteria and viruses is strong.Medical surgical masks can also be used for anti-flu.
Baidu Encyclopedia
Medical surgical mask, English is Surgical Face Mask.Medical surgical masks are the cheapest masks in several valid masks.They are also the most comfortable masks.Based on medical use standards, medical surgical masks have good granular interception capabilities, although although althoughThe overall sealing is not as good as N95, KN95 or KF94, but a research certificate in Italy 【source】 The medical surgical mask made of fabric manufacturing from 3 or more layers can provide excellent filtration efficiency while ensuring good breathability, so it can become a protective mask used for daily use.

Can anti-virus masks prevent new coronary virus virus?
The answer is yes.
If you are infected with high-risk areas and at the same time, you can’t buy a mask, then you can also consider half-face anti-virus mask.
