Mask type:
Paper mask: it is mostly used in food processing industry to ensure the cleanliness of production process, but it has no filtering function, is easy to wet and break, and is not durable.
Absorbent cotton gauze mask: commonly used masks are made of absorbent cotton gauze folded several layers, and also made of non-woven fabrics. Generally speaking, a three-layer gauze mask can only block 70%-80% of bacteria, and a six-layer gauze mask can block more than 90% of bacteria. Usually 6 to 8 layers of gauze masks will not feel too boring after wearing them. Because SARS virus is mainly transmitted by close contact and droplets, and its toxicity is strong, it is generally recommended to use gauze masks with layers of 12 to 16.
Three-layer surgical mask: the middle filter can block particles over 5 microns (65438+ one millionth of a meter), with good ventilation effect, comfortable wearing and convenient use. There are two types: ear hanging type and strap type.
Activated carbon mask: a functional mask specially designed for anti-virus, which has good disinfection, sterilization, deodorization and dustproof functions. The built-in iron wire bends according to the face shape, effectively closing the gaps on both sides of the nose and forming a good ventilation space for the nose and mouth.
N95 mask: It conforms to N95 approval of National Occupational Safety and Health Association (NIOSH), and the diameter of filter particles can be as small as 0.3 micron. Tests show that it can block particles with a diameter of 0.075 micron up to 95% (the diameter of coronavirus is about 0. 1-0. 12 micron).
Three-dimensional mask: the mask protrudes forward, leaving enough space for the nose and mouth to protect the nose, mouth and lips from oppression, comfortable to wear and convenient to talk to people.
Bamboo charcoal mask: "Zhaowen brand" bamboo charcoal mask produced by Zhaowen Bamboo Industry Co., Ltd. in Suichang County, Zhejiang Province, puts bamboo charcoal particles burned at ultra-high temperature into the mask, makes full use of the dehumidification and super adsorption of bamboo charcoal to generate negative ions, and has special effects such as purifying air and filtering harmful substances and germs. Bamboo charcoal masks are very popular overseas.
Mask is a sanitary product, which generally refers to a device worn on the nose and mouth to filter the air in and out of the nose and prevent harmful gases, smells and droplets from entering and leaving the nose and mouth of the wearer. It is made of gauze or paper.
Masks have a certain filtering effect on the air entering the lungs. Wearing a mask has a very good effect when respiratory infectious diseases are prevalent and when working in polluted environments such as dust.
Masks can be divided into air filtration masks and air supply masks.
Question 2: What kind of professional mask should I buy? 10: After glass fiber inhalation, it is easy to suffer from lung tumor and pneumoconiosis.
According to GB2626-2006 "Dust Mask" standard, the protection grades of filter cotton are KN 100, KN95 and kn90 respectively. Among them, KN 100 can protect more than 99.97% of ultrafine dust. The protection rate of KN95 is above 95%, and KN90 is above 90%. If the dust concentration in the working environment is high or toxic and harmful, it is recommended to choose KN 100 professional dust mask.
Scientific selection of dust mask certified by GB2626-2006 standard is helpful to prevent lung injury.
1, select the composite half mask type. Disposable masks have high air leakage rate and are not suitable for long-term protection.
2. Choose KN 100 dustproof filter cotton for use. Because glass fiber is harmful to the respiratory system. It is easy to cause pneumoconiosis and tumor. Low protection rate will lead to physical injury.
3, the choice of silicone material is more comfortable. Suitable for long-term wear, not easy to cause allergic reactions. A mask with high hardness is easy to cause facial depression.
4. The size of the mask is extremely important. Don't buy those so-called universal masks. Easy to leak.
The mask covers the nose and mouth, and covers the nose, mouth and chin. The latter is recommended, and this design is adopted by international high comfort masks.
6. It is recommended to choose a mask with smooth breathing. Some masks are designed with double filter cotton, and the filter cotton has two sides, which makes the mask breathe relatively smoothly.
Question 3: It's best to know what masks are like in Beijing. To tell the truth, if there is no good mask in Beijing, any mask should be washed and changed frequently, which is the most hygienic. Don't use the mask marked disposable for the second time, because you can only filter one layer, and it won't work if you filter it once. Filters should also be replaced frequently.
Question 4: What brand of mask is better? 1, disposable 3-layer non-woven medical mask
Function: It can filter particles in the air and block droplets and secretions.
Where can I buy it? Ordinary pharmacies and Taobao shops. The price of pharmacies is generally around 4 yuan.
Advantages: relatively breathable, light weight, easy to carry and cheap.
Disadvantages: the effect of blocking dust particles is not good, and it can only be used once.
2. Pure cotton gauze mask (4 layers, 12 layers, 16 layers)
Function: it can filter some air particles, block droplets and secretions, and has strong adsorption capacity.
Where can I buy it? Ordinary pharmacies, Taobao stores and pharmacies are generally priced in 3 yuan.
Advantages: it can be reused after cleaning, and the price is cheap.
Disadvantages: poor air permeability, allergic skin should not be worn; Generally, the fiber is very thick, and the dust-proof efficiency for dust with a diameter less than five microns is limited, only about 10%; The part of the mask that touches the nose and mouth will leave saliva. If you don't clean it often, it is easy to breed bacteria.
3, N95 mask
N95 mask is one of nine kinds of anti-particle masks certified by NIOSH (National Institute of Occupational Safety and Health). "N" means particles that are not suitable for oiliness (cooking fumes are oily particles, but droplets produced by people talking or coughing are not oily); "95" means that the filtration efficiency reaches 95% under the detection conditions specified by NIOSH standard. N95 is not a specific product name. As long as the product meets the N95 standard and passes NIOSH review, it can be called "N95 mask".
Effect: it can prevent droplet infection and has a certain effect on PM2.5 particles.
Where can I buy it? Online shop, the price is generally 20-30 yuan.
Advantages: there are four plug-in filters, which have good protection and filtration effect.
Disadvantages: the density is too high, and it is airtight, so it will be uncomfortable for ordinary people to wear.
4, dust mask (activated carbon mask)
Function: it has certain dustproof, antibacterial and antiviral effects, but its protective effect on PM2.5 is limited. * * * There are four layers, namely, all cotton cloth, dust-proof card clothing, activated carbon (filter layer) and all cotton honeycomb cloth from the surface to the inside, which has good filterability. Generally, a piece of activated carbon filter layer will be presented for daily replacement.
Where can I buy it? The prices of ordinary pharmacies, Taobao shops and pharmacies are generally 10 yuan/tablet. There are two kinds: children and adults.
Advantages: active carbon is added to effectively absorb odor; Arch shape, which fits the facial curve and is more comfortable to wear; Reusable.
Disadvantages: insufficient ventilation and inconvenient to carry.
What brand of anti-fog mask is good?
In recent years, smog has been rampant, and people have begun to pay attention to anti-smog pm2.5 masks. After several months of market research and summarizing consumers' recognition and satisfaction with products, many media summarized seven brands:
No.65438 +0: Nine-headed Eagle nano pm2.5 anti-fog mask
Second place: 3m dust mask
Third place: Kimberly mask
Fourth place: Baianda dust mask
5 th place: Iger dust mask
Sixth place: Ni Wei dust mask
No.7: northern dust mask
Matters needing attention in wearing anti-fog mask
If people with respiratory diseases, the elderly, children, pregnant women and other special groups, you can wear masks when you go out, but don't wear them for a long time. The choice and wearing of masks are particular. The higher the PM2.5 index, the thicker the mask and the better the sealing performance. While effectively preventing PM2.5, it is not comfortable to wear, and it is easy to give people a sense of suffocation, which is not suitable for wearing for a long time.
It is not practical for ordinary citizens to use professional medical masks, especially N95 masks, because improper wearing methods and long wearing time will lead to respiratory problems. Some people experienced wearing masks and found that N95 masks were hard in texture and the protective materials were relatively airtight. After wearing it for less than 20 seconds, I feel uncomfortable and my breathing is not smooth. The mask is also clearly marked: improper use can lead to disease and even death.
This is because the mask will not provide oxygen, on the contrary, it will increase the respiratory resistance to varying degrees. The power of breathing comes from the movement of respiratory muscles such as diaphragm, which means that the wearer needs to spend more effort to realize gas exchange. For men who don't exercise regularly to maintain heart and lung function, this consumption is irrelevant, but it is different for old, weak, sick and disabled children with weak respiratory muscles or poor heart and lung function. The harm caused by airway obstruction and hypoxia may exceed the risk caused by particulate matter itself, so these people need to be cautious about wearing masks. But at the same time, the respiratory tract of the old, the weak and the sick is greener than ours ... >; & gt
Question 5: What brand of mask is better? There are 3m masks, Honeywell masks, Kimberly masks, Delta masks and so on. , but it is best to choose the one that suits you. Whether the mask is selected correctly or not is the premise of whether your respiratory protection can achieve truly effective protection. 1. In order to achieve real safety, comfort and economic protection, we suggest that you choose KN 100 dust mask.
2. Try to choose a mask with LA certification. Choose a mask with protection level of KN95 or KN 100.
3. Try to choose a silicone mask. Comfortable to wear, low respiratory resistance. Only in this way can we go out safely in foggy days, give ourselves a healthy life and add points to our health.
Question 6: What brand of mask is better? Choosing a good mask is actually not that difficult. The material, texture and comfort of the mask are very important.
I chose the mask just for comfort and beauty, hehe!
Question 7: What mask is better for dust prevention? Ordinary masks should be useless. A mask with good filterability and good sealing will do. Medical masks can be divided into ordinary masks and advanced masks. Ordinary medical masks are not expensive and the protection is not outstanding; Surgeons or dentists adopt advanced medical masks, which pay attention to the filtration of particles and the barrier of fluids, so as to ensure the breathability of wearing in a precise working environment. Haze refers to the haze caused by dust, sulfuric acid and nitric acid in the air. The difference between haze and fog is that the relative humidity is small when haze occurs, but it is saturated in fog (if there are a large number of condensation nuclei, the relative humidity may not reach 100%, and saturation may occur). Sources of toxic particulate matter in cities: firstly, automobile exhaust. Cars that use diesel have the highest emission standards. Medical masks imported from the United States, like Wei Xin who works in Beijing, have good filterability, not only preventing particles, but also preventing droplets. When choosing a mask, you can look at the standard and filtration efficiency. You should be familiar with 3X brand N90 and N95 series masks, both of which are named after NIOSH standard. In addition to NIOSH standard, ASTM standard of American Society for Testing Materials, KN standard of China and FFP standard of Europe are all universal and can be used to measure important indicators of masks. Ordinary medical masks are relatively cheap and have poor protection, and are basically only suitable for ordinary nurses or cooking at home. Advanced medical masks are adopted by surgeons or dentists, who earn more and pay more attention to the quality of masks rather than the low cost. Advanced medical masks have excellent barrier to particles and liquids, ensuring breathability when worn in precise working environment. It can also deodorize. Sources of toxic particles in cities: first, automobile exhaust, medical masks imported from the United States, and Puwei server, which have good filterability and prevent both particles and fog drops. The filtration efficiency is 99.8% for particles as small as 0. 1 micron, and 99.9% for bacteria or virus carriers as small as 0.3 micron (common in droplets). SecureFit patented technology is adopted to adapt to different face shapes and achieve a high degree of fit. For the health of you and your family, wear a mask when you go out. I wish you happiness and hope to adopt it.
Question 8: What kind of mask should I wear? Breathing-independent electrostatic activated carbon mask adopts patented nose-mouth separation design, and there is an opening design in the middle of the mask part, so you can flexibly choose to cover your mouth or nose, which is more breathable and comfortable. Especially for customers who wear glasses, part of the exhaled gas can escape through the middle opening, and the glasses will not be directly polluted by water vapor and fogged.
Question 9: How to choose a dust mask? What is the standard? What kind of dust mask is good? Hello, there are many kinds of products in the dust mask market with different quality. I suggest you consider the following four aspects when choosing a good dust mask:
1. Safety performance, according to the standard of GB2626-2006, the dust mask with the highest protection level in China is N 100, which can filter ultrafine dust up to 99.97%, meeting the needs of most working conditions.
2. Comfort, the mask made of the material closest to human skin is the most comfortable. At present, the best masks on the market are made of advanced medical silicone materials, and the respiratory resistance of cotton filter must be low to improve work efficiency.
3. Simple and convenient, people don't have much time to take care of a mask when using it, so we must choose a mask with good convenience.
Finally, economy must be considered. Choosing a dust mask with long service life and good quality can reduce the investment of comprehensive protection cost.
The above are some experiences I have summarized according to the current dust mask market. I have tried a product that guarantees Shun 'an in the market at present, and I feel that the quality and protective effect are better than other products.
If you choose a dust mask, it is recommended to choose a mask as follows:
1, dust mask as a special labor protection articles, must pass the certification of GB2626-2006.
2. Masks are divided into disposable, replaceable cotton filter-type half masks and full masks. For long-term occupational protection, it is recommended to use a replaceable cotton half mask.
3. The mask material is silica gel, plastic, etc. Silicone material is soft and comfortable, with low facial pressure.
4. For dust and oily particles, protective masks are divided into oil-proof (oil fume, oil mist, dust, smoke, fog and microorganisms, denoted by KP) and dustproof (dust, smoke, fog and microorganisms). There are three levels of protection against dust: KN 100, KN95 and KN90. If there are many kinds of pollutants in the working environment, which are harmful to people, it is suggested to choose KN 100.
It is particularly important that the mask is sized according to the national standards. Many masks vary in size, and the effect will vary from person to person.
6. There are two kinds of masks, one is to cover the mouth and nose, and the other is to cover the mouth, nose and jaw. The second contact mask is large, with good sealing and low pressure sensitivity.
7. Choose one with low respiratory resistance. According to the national standard, the inspiratory resistance is less than 350 Pa, and some of them are only about 120 Pa, so the breathing is smooth. Masks with high respiratory resistance can easily cause lung diaphragm injury.
Don't neglect respiratory protection, use fake, fake, gauze, towels, etc. As a mask, it is easy to cause lung diseases. At present, some common dust masks with N 100 grade can ensure the protective effect and breathe smoothly, and the cost is about one yuan a day, which can be borne by enterprises and individuals at their own expense. There are generally Baoshun 'an, 3M8233 and Shengbao in China.
Question 10: What kind of anti-fog mask is the best? 5 points CCTV has done the test, the bowl filter is the best, the folding type is the second, and the flat plate and cotton cloth are the worst.
It is recommended to buy 3M 6200 series half mask +600 1 filter box +209 1 filter screen.
Personal protection series is still 3M reliable!
