2020-02-21

对于现在的冠状病毒,你知道你应该买哪种类型的口罩吗?

Do you know what type of mask you should buy for coronavirus?


医用口罩、医用护理口罩、医用外科口罩、医用防护口罩、N95、KN95、3M等等,关于口罩的名字,看的人眼花缭乱,一团乱麻。

Medical masks, medical nursing masks, medical surgical masks, medical protective masks, N95, KN95, 3M, etc. Regarding the names of the masks, people were dazzled and confused.




常用口罩类型根据使用标准 ,可分为大致6类

The common mask types can be divided into roughly 6 categories according to the standard of use


医用外科口罩、医用防护口罩、N95、FFP2都可用于医疗机构防护,KN95不可用于医疗机构,但普通民众可自行选择。

Medical surgical masks, medical protective masks, N95, FFP2 can be used for the protection of medical institutions, KN95 can not be used for medical institutions, but ordinary people can choose.


不同类型的口罩到底该怎么选?今天给大家分类介绍一下,让你快速选择适合自己的口罩。

How to choose different types of masks? Today, I will introduce them to you, let you quickly choose the mask that suits you.


 1、医用口罩/医用护理口罩 

医用口罩和医用护理口罩属于国家标准,YY0969,多为企业自己设计制作。其构成大多为无纺布和过滤纸。

1.Medical masks / medical care masks

Medical masks and medical care masks belong to national standards, YY0969, and are mostly designed and manufactured by enterprises. Its composition is mostly non-woven fabric and filter paper.


这类口罩无法保证对病原微生物、粉尘的过滤性,达不到对颗粒和细菌的过滤效率,不能有效阻挡病原体通过呼吸道的入侵。

Such masks cannot guarantee the filterability to pathogenic microorganisms and dust, cannot reach the filtration efficiency of particles and bacteria, and cannot effectively prevent the invasion of pathogens through the respiratory tract.


这类口罩仅限于对粉尘颗粒或气溶胶起到一定的机械阻隔作用,在医院中一般用于常规护理,防护效果不是很理想。

This type of mask is limited to a certain degree of mechanical barrier to dust particles or aerosols. It is generally used for routine care in hospitals, and the protective effect is not very satisfactory.



 2、医用外科口罩 

医用外科口罩必须参照医药标准YY0469-2011进行生产,如果企业自己设置的企业标准符合甚至高于YY0469的要求,也可以印在口罩外包装上。

2.Medical surgical masks

Medical surgical masks must be produced in accordance with the medical standard YY0469-2011. If the enterprise standard set by the enterprise meets or exceeds the requirements of YY0469, it can also be printed on the outer packaging of the mask.


外科口罩分为三层 :内部吸水层,中间过滤层,外面防水层。其对非油性颗粒的过滤效果应达到30%以上,对细菌的过滤性要达到95以上(非N95)。

The surgical mask is divided into three layers: the inner water-absorbing layer, the middle filter layer, and the outer waterproof layer. Its filtering effect on non-oily particles should be more than 30%, and its filtering property on bacteria should be above 95 (non-N95).


适用于医务人员或相关人员的基本防护,能阻止血液、体液和飞溅物的传播,具有一定的呼吸防护功能。医用外科口罩可以阻隔大部分细菌和病毒,能减少医院交叉感染的风险。

It is suitable for the basic protection of medical personnel or related personnel, can prevent the spread of blood, body fluids and splashes, and has certain respiratory protection functions. Medical surgical masks can block most bacteria and viruses and reduce the risk of cross infection in hospitals.


主要用于医疗门诊、实验室、手术室等高要求的医疗环境,安全系数相对较高,对细菌、病毒的抵抗能力较强。主要用于预防流感、呼吸系统疾病的传播。

It is mainly used in high-demand medical environments such as medical clinics, laboratories and operating rooms, with a relatively high safety factor and strong resistance to bacteria and viruses. It is mainly used to prevent the spread of influenza and respiratory diseases.


 3、 KN型口罩

KN型口罩主要用于防护非油性颗粒物的口罩。根据GB2626标准要求,对非油性颗粒物的过滤进行了划分。其中KN90是对于0.075微米以上的非油性颗粒物过滤效率大于90%,KN95是对于0.075微米以上的非油性颗粒物过滤效率大于95%,KN100是对于0.075微米以上的非油性颗粒物过滤效率大于99.97%.

3.KN mask

KN masks are mainly used to protect non-oily particles. According to the requirements of GB2626 standard, the filtration of non-oily particles is divided. Among them, KN90 is more than 90% for non-oily particulate matter above 0.075 microns, KN95 is more than 95% for non-oily particulate matter above 0.075 microns, and KN100 is more than 99.97% for non-oily particulate matter above 0.075 microns.



KN型口罩关于滤料的要求为,直接与面部接触的材料对皮肤无害,滤料对人体无害,所用材料应具有足够的强度,在正常使用寿命中不应出现变形或破损。

The requirements of KN type masks on filter materials are that the materials in direct contact with the face are not harmful to the skin and the filter materials are not harmful to the human body. The materials used should have sufficient strength and should not be deformed or damaged during normal service life.


和KN同系列的口罩,还有一个KP系列,那KP是什么?

KN是针对非油性颗粒物,而KP是针对油性颗粒物的口罩,其中KP90/95/100同理对其KN中的KN90/95/100.

The same series of masks as KN, and a KP series, what is KP?

KN is for non-oily particles, and KP is a mask for oily particles. KP90 / 95/100 is the same as KN90 / 95/100 in KN.


KN与KP型口罩主要适用于有色金属加工、冶金、钢铁、炼焦、有机化工、煤气、建筑、装饰等产生的0.185微米以上的粉尘、烟、雾等油性及非油性颗粒物污染物的行业。(注:也可以称其为防尘口罩)

KN and KP masks are mainly suitable for oily and non-oily particulate pollutants such as dust, smoke, fog and the like produced by non-ferrous metal processing, metallurgy, iron and steel, coking, organic chemicals, gas, construction, and decoration. (Note: it can also be called a dust mask)


 4、 医用防护口罩 

我国医用防护标准为GB19083-2010,在这个标准里没有N95的说法,而是采用1级、2级、3级的划分来表示过滤效率的等级。

4.Medical protective masks

China's medical protection standard is GB19083-2010. There is no N95 statement in this standard, but the classification of level 1, 2, and 3 is used to indicate the level of filtering efficiency.


1级就可以达到N95的要求。也就是说,只要符合GB19083标准的任何医用防护口罩,就绝对已经达到N95和KN95的过滤效率了。

Level 1 can meet the requirements of N95. In other words, as long as any medical protective mask that meets the GB19083 standard, it will definitely reach the filtration efficiency of N95 and KN95.


医用防护口罩和KN95的不同在于,医用防护口罩还有“合成血液穿透”和“表面抗湿性”参数要求。明确了医用防护口罩对血液、体液等液体的防护效果,而这些KN型是没有的。

The difference between medical protective masks and KN95 is that medical protective masks also have "synthetic blood penetration" and "surface moisture resistance" parameter requirements. The protective effect of medical protective masks on blood, body fluids and other liquids was clarified, but these KN types are not available.



所以,符合GB2626的KN型口罩,是不能用于医疗操作的,特别是气管切开、气管插管等有可能喷溅的高危操作。

Therefore, KN-type masks conforming to GB2626 cannot be used for medical operations, especially high-risk operations such as tracheotomy and tracheal intubation that may splash.


医院的外科口罩都是必须是符合GB19083的1级以上的口罩。既能达到95%的过滤性,也能防液体渗透。

Surgical masks in hospitals must all meet the level 1 and above of GB19083. It can achieve 95% filtration, and it can prevent liquid penetration.


说完这些,很多人也会问,那N95是什么?

After saying this, many people will also ask, what is N95?


上面介绍的几种口罩,医用口罩和医用外科口罩遵循的是医药标准,医用防护口罩和KN型遵循的是国家标准,而N95遵循的是美国标准。

The several types of masks introduced above, medical masks and surgical surgical masks follow medical standards, medical protective masks and KN models follow national standards, and N95 follows US standards.


 5、 N95口罩 

N95口罩遵循的是美国NIOSH42CFR84-1995标准(NIOSH美国国家职业安全卫生研究所)。N表示不耐油,95表示暴露在规定数量的专用试验粒子下,口罩内的粒子浓度要比口罩外粒子浓度低95%以上。95不是平均值,是最小值。

5.N95 mask

The N95 mask follows the American NIOSH42CFR84-1995 standard (NIOSH National Institute of Occupational Safety and Health). N indicates oil resistance and 95 indicates exposure to a specified number of special test particles. The particle concentration in the mask is more than 95% lower than the particle concentration outside the mask. 95 is not an average, it is a minimum.


过滤范围是针对非油性颗粒物,如粉尘、酸雾、微生物等。其使用范围为,医务人员和相关工作人员对经空气传播的呼吸道传染病的防护,以及在创操过程中阻止血液、体液、飞溅物的传播 。

The filtering range is for non-oily particles, such as dust, acid mist, microorganisms, etc. Its application scope is the protection of airborne respiratory infectious diseases by medical staff and related staff, and the prevention of the spread of blood, body fluids and splashes during the procedure.



NIOSH认证的其他防颗粒物口罩级别还包括:N95、N99、N100、R95、R99、R100、P95、P99、P100,共9种。

NIOSH certified other anti-particulate mask levels also include: N95, N99, N100, R95, R99, R100, P95, P99, P100, a total of 9 types.


注:N—不耐油,R—耐油,P—防油。

Note: N—not oil resistant, R—oil resistant, P—oil resistant.


KN95型口罩和N95型口罩这两个级别的技术要求、测试方法等基本一致,只是分属于不同国家的标准。

The technical requirements and test methods of the two levels of KN95 masks and N95 masks are basically the same, but they belong to different national standards.


N95遵循的是美国标准,而FFP2型遵循的是欧盟标准。

N95 follows the American standard, while FFP2 follows the European standard.



 6、 FFP2口罩 

FFP2口罩是欧洲口罩标准EN149:2001中的一种,作用都是将有害气溶胶,包括粉尘、熏烟、雾滴、毒气和毒蒸气等经滤料吸附,阻挡而不被人所吸入。

6.FFP2 mask

FFP2 masks are one of the European mask standards EN149: 2001. They are used to adsorb harmful aerosols, including dust, smoke, mist droplets, toxic gases and toxic vapors, through the filter material, blocking them from being inhaled by people.


其中,FFP1:最低过滤效果》80%,FFP2:最低过滤效果》94%,FFP3:最低过滤效果》97%。如果用这个数据来选择适合这次疫情的口罩,最低要选FFP2。

Among them, FFP1: The lowest filtering effect> 80%, FFP2: The lowest filtering effect> 94%, FFP3: The lowest filtering effect> 97%. If you use this data to select a mask suitable for this epidemic, the minimum is FFP2.


FFP2型口罩的滤料,主要分四层,即两层无纺布 + 一层溶喷布 + 一层针刺棉。

The filter material of the FFP2 mask is mainly divided into four layers, that is, two layers of non-woven fabric + one layer of solvent spray cloth + one layer of needle punched cotton.


FFP2防护口罩,可以防护极细的病毒、细菌,94%以上的过滤效率,更适合湿热环境或长时间佩戴防护。

FFP2 protective mask can protect very fine viruses and bacteria, with a filtration efficiency of more than 94%, which is more suitable for hot and humid environments or long-term protection.



最后一个问题,什么是3M口罩?

Last question, what is a 3M mask?


“3M口罩”指所有3M公司生产的可以叫做口罩的产品,按大类可分为医用口罩、颗粒物防护口罩、舒适保暖口罩三类,每类口罩各有不同的防护侧重点。

"3M masks" refer to all 3M products that can be called masks. They can be divided into three categories: medical masks, particulate protective masks, and comfortable warm masks. Each type of mask has a different protective focus.



3M医用防护口罩分有国产和进口,具备了医用外科口罩和颗粒物防护口罩的防护性能,是在医院专用的,能过滤空气中的颗粒物,并阻隔飞沫、血液、体液和分泌物的防护口罩。

3M medical protective masks are made in China and imported. They have the protective properties of medical surgical masks and particulate protective masks. They are used in hospitals and can filter particulates in the air and block droplets, blood, body fluids and secretions.


3M口罩中,90、93、95、99开头的,是高效防护有害颗粒口罩,8210和8118s的均符合我国防护PM2.5的要求,如果要选用达到世界卫生组织流感防护要求的,则选用9010、8210、8110s、8210v、9322、9332的。

Among 3M masks, the ones starting with 90, 93, 95, and 99 are highly effective masks for protecting against harmful particles. Both 8210 and 8118s meet the requirements of China's PM2.5 protection. If you want to choose to meet the World Health Organization influenza protection requirements, choose 9010 , 8210, 8110s, 8210v, 9322, 9332.


看到这里,知道疫情期间要怎么选购口罩了吗?

1、能选医用外科口罩,尽量选择外科口罩。

2、能选没有呼吸阀的口罩,尽量选择没有呼吸阀的口罩。

Seeing this, do you know how to choose a mask during the epidemic?

1, can choose medical surgical masks, try to choose surgical masks.

2, can choose a mask without breathing valve, try to choose a mask without breathing valve.
