Question 2: Which is the best dust mask? There is no such thing as the best. Honeywell (USA) and Doelger (Germany) are relatively high-end.
The process and effect are well balanced.
Question 3: What are the best dust masks? What are the best dust masks? Society, economy and science are constantly developing.
Do a good job of respiratory protection. Choose a dust mask scientifically and choose a good mask with good protective effect, smooth breathing and economical use. Helps prevent lung injury.
Methods of cleaning dust: Now masks must implement GB2626-2006 standard. Dust masks are divided into KN 100, KN95 and KN90. Among them, the protective effect of KN 100 on ultrafine dust can reach nearly100% (more than 99.97%). If the particle size is large, you can choose KN95 grade.
The protective effect of dust mask depends on two aspects. One is the filtration efficiency of cotton filter. The second is the tightness of the mask and the face.
Therefore, masks must be divided into different sizes, and the fitting effect of masks with different sizes and different faces varies from person to person.
Methods of cleaning dust: Scientific selection of dust masks certified by GB2626-2006 is helpful to prevent lung injury.
1, select the composite half mask type. Disposable masks have a high air leakage rate and are not suitable for long-term or occupational protection.
2. Choose KN 100 dustproof filter cotton for use. 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. Suggest using the latter, which is relatively comfortable.
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. Through the above methods, you can find a mask with good protective effect.
Question 4: Which is better, the industrial dust mask? There are many kinds of industrial dust masks. They should be selected according to dust concentration and toxicity. All industrial dust masks are suitable for the environment in occupational exposure limits where the concentration of harmful substances does not exceed 10 times. Otherwise, a full-face mask or respirator with higher protection level should be used.
If the particulate matter is highly toxic, carcinogenic and radioactive, the filter material with the highest filtration efficiency should be selected. If the particulate matter is oily, you must choose a suitable filter material. If the particles are needle-like fibers, such as slag wool, asbestos, glass fiber, etc. Because industrial dust masks can't be washed, masks with tiny fibers are easy to cause facial * * * phenomenon at the sealing part of the face, so they are not suitable for use.
Matters needing attention in purchasing industrial dust masks:
1, dust mask safety, safety is mainly reflected in the dust mask protection level, each brand of dust mask has its protection level N90, N95, N 100, the higher the level of ridge mask, the better the dust-proof effect and the higher the safety, and the protection level of each brand must be certified by the safety sign management center of special labor protection articles.
2. Comfort of the dust mask. As far as the dust mask half mask is concerned, the advanced imported silicone material is softer, more comfortable and extremely skin-friendly, which makes the dust mask perfectly combined with the face, comfortable and safe.
3. Service life of dust mask: Wear a safe and comfortable dust mask. Although the initial cost of dust mask is high, the longer its service life, the lower its use cost and more economical.
Question 5: What mask is the best for dust prevention? If you want to buy a dust mask with good protective effect, you must first know these points before you can buy a dust mask with safe protection.
So how to choose a dust mask? It is suggested to choose a mask in the following ways: 1. Dust masks, as special labor protection articles, must pass GB2626-2006 certification. 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, represented by KP) and dustproof (dust, smoke, fog and microorganisms, represented by KN). 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 6: 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 7: What kind of mask can prevent dust? If the dustproof effect is good, it is recommended to choose KN 100 composite semi-mask. The protective effect of the mask depends on the air leakage rate after the mask is matched with the face and the protective level of the cotton filter. Among them, KN 100 mask filter cotton can protect non-oily particles with a particle size of 75 nm, and the protection efficiency is over 99.97%.
It is suggested to scientifically select dust masks in the following ways.
Methods of cleaning dust: Now masks must implement GB2626-2006 standard. Dust masks are divided into KN 100, KN95 and KN90. Among them, the protective effect of KN 100 on ultrafine dust can reach nearly100% (more than 99.97%).
Second, masks must be divided into different sizes, and the fitting effect of masks with different sizes and faces varies from person to person.
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. 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. Suggest using the latter, which is relatively comfortable.
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 8: What kind of dust mask is better? You can choose dust masks with breathing valves, such as 3m9001v9002v903v, Youweisi 33 10, 3220, 32 10, 22 10 and so on.

Question 9: What mask is the best? The survey shows that. The best dust mask has always been pursued by front-line dust workers. So what is the best dust mask? A mask with good effect and smooth breathing can basically satisfy everyone. Therefore, how to choose the best dust mask, Bao Shun 'an teaches you to consider comprehensively from three aspects: safety, comfort and economy. This is the best principle for purchasing dust masks:
First, the security analysis:
1, the higher the protection level, the safer the dust mask, and the protection level of the dust mask is the filtration efficiency of ultrafine dust. The best dust mask is currently based on the latest GB2626-2006 standard. Dust masks are divided into KN 100, KN95 and KN90, among which KN 100 has the highest grade and the best filtering effect. KN 100 is the best dust mask)
2. The best dust mask can be perfectly combined with the face. The filtration efficiency of KN 100 dust mask is above 99.97%, but when it is worn on the faces of workers with different faces, ensuring perfect combination is the second key to safety. Therefore, the best dust mask should be perfectly combined with the face.
3. The tightness of the exhalation valve. Ensure that the exhalation valve is closed in reverse. At present, the advanced imported silicone exhalation valve can better improve the safety.
Second, the comfort analysis:
1, dust mask is always combined with the face, so choose the dust mask with the best skin friendliness. At present, high-grade imported food-grade silica gel is nontoxic, colorless and tasteless.
1/2
It has excellent skin friendliness. Dust masks made of plastic, rubber, plastic and other materials can not only be perfectly combined with the face, but also cause secondary harm to the human body.
2. The best dust mask has low respiratory resistance, and front-line workers need to spend a lot of physical strength in their work. The dust mask with low breathing resistance is an important embodiment of comfort.
3. Economic analysis:
1, the next consideration is economy. Because dust masks are used to protect health. Choose a dust mask and a dust mask with a long service life, that is, calculate the comprehensive protection cost. If one 1 yuan can be used for one day, the quality is poor and the protection level is low; One is 100 yuan, which has been used for half a year and has the best quality and guarantee level. There is no doubt that you choose the second option. The former has spent money but failed to achieve effective protection, costing about 1 yuan per day, while the latter has been effectively protected, costing about 0.6 yuan per day. This is the qualitative difference. The economy needs comprehensive consideration.
Through the above, Bao Shun 'an N 100 dust mask can achieve the above effects.
