N95 face mask have so many models, would you pick them? Can the mask have a breathing valve? 3M N95 face mask model inventory.
What are N95, R95, and P95 face masks? What are the differences? How often do N95 face masks need to be replaced? Today I will do homework for 3M N95 face masks for you. Check out the differences between the functions of each model of 3M N95 face masks, and how to choose the one that suits you from each model of 3M N95 face masks.
N95 face masks comply with NIOSH (National Institute of Occupational Safety and Health) standards and can filter 95% of non-oily particles with a diameter of 0.3 microns or more in the air. As long as they meet the N95 standard and pass the NIOSH review, the particulate filter mask respirator can be called the N95 face mask.
N95 face masks in the United States are mainly industrial protective masks, which are dust masks that meet NIOSH standards. For some dusty working environments, N95 face masks can prevent the inhalation of harmful airborne particles. N95 face masks are also good for mountain fire smoke pollution. Protective effect. If you want to do carpentry and mix cement at home, you may also consider wearing N95 face masks protection.
2. What are the differences between N95, R95, and P95 face masks?
N95 is one of NIOSH’s ratings for the protection standards of particulate filter mask respirators. “N” means Not resistant to oil, and “95” means that the filtration efficiency is 95% or more. In addition to 95, there are grades of N99 (filtration efficiency not less than 99%) and N100 (filtration efficiency not less than 99.97%).
“R” means Somewhat resistant to oil, “P” means Strongly resistant to oil/Oil-proof. Both R95 face masks and P95 face masks can filter 95% of non-oily particles and oily particles with a diameter of 0.3 microns or more in the air. The service life of R95 face masks is up to 8 hours, and the service life of P95 face masks can be up to 40 hours or 30 days. R series and P series masks also have R99/R100 and P99/P100 classification.
N95 is the standard of the United States. Other countries and regions in the world also have the same type of mask, but the name is different. For example, it is also called the KN95 face mask in China.
As can be seen from the above, N95 is actually the lowest standard among the 9 classifications formulated by NIOSH for the protection standards of dust masks.
Medical-surgical masks can isolate large particles such as droplets, and the outer layer is a waterproof layer that can block liquid splashes. However, surgical masks cannot effectively filter the fine particles in the air, and the design of surgical masks is not sealed, and it cannot completely prevent air from entering the gaps on the edges of the mask.
N95 face masks are particulate protective masks that can filter tiny particles with a diameter of more than 0.3 microns, but each time you wear an N95 face mask, you must test the tightness of the edges of the mask to ensure that there is no air leakage to have a real protective effect.
Industrial N95 face masks are mainly used when the air quality is not good. It can prevent or reduce the dust, pollen, and germs in the air from entering the human respiratory organs, such as preventing smog and PM2.5. N95 face masks can also filter bacteria and viruses with a diameter of 0.3 microns or more, so whenever a large epidemic infectious disease spreads, N95 face masks are also a popular choice for everyone.
But in fact, for the prevention of bacterial infections in the air such as influenza or Wuhan pneumonia, ordinary people choose medical surgical masks to be more cost-effective. First of all, N95 face masks can only block 95% of the particles, and wearing N95 face masks must also follow strict procedures. If they are used incorrectly, the protective effect will be greatly reduced. According to a study published in 2008 by the International Journal of Infectious Diseases, the correct use of masks can effectively reduce the spread of influenza virus infection. However, the use of P2 masks without gas density testing is not significantly different from the use of medical surgical masks.
And another study data shows that wearing only a mask has no preventive effect, but the combination of wearing a mask and washing hands frequently can reduce the chance of getting an influenza disease by 75%. Therefore, to prevent infection, the most important thing is to wash your hands frequently!
4. Is there any difference between different styles of N95 face masks?
N95 face masks have many different colors, shapes, and styles to choose from. Some shapes and styles can better fit some people’s facial shapes and will be more suitable for individuals.
According to CDC, as long as it is a product approved by NIOSH, used in an environment that meets the requirements of OSHA regulations, and the user wears a mask to test to ensure the gas density, then no matter what color, shape or style of N95 face mask, can achieve the same expectations The protective effect, that is, “the filtration efficiency of non-oily particles with a diameter greater than 0.3 microns in the air reaches more than 95%”.
5. How long can N95 face masks be worn?
According to the instructions on the 3M official website, the service life of N95face masks does not have a clear time limit, just saying “When the mask is dirty, damaged, or you feel difficulty breathing, you must leave the contaminated area and replace with a new mask.”
According to CDC instructions, practical experience shows that N95 face masks can be used continuously or intermittently within 8 hours to maintain the effect. Whether they can be used for a long time depends on whether the N95 face masks are dirty, whether they can continue to seal, and whether they affect smooth breathing; repeated use of N95 face masks is required Pay attention to the problem of cross-contamination, and because the circumstances are different, the maximum number of safe reuse of N95 face masks cannot be determined.
The CDC also stated that using N95 face masks for an extended period of time is better than taking them off and putting them on again, which can reduce the possibility of contamination. Especially in an environment where there are epidemic bacteria in the air, if the mask is removed, it is difficult to ensure that the bacteria will not adhere to the inside of the mask.
3M is a world-renowned American manufacturing company, formerly known as the Minnesota Mining and Manufacturing Company. It produces a lot of high-quality industrial products, as well as medical supplies and household products. I believe that every small partner has used several 3M products. The N95 face masks produced by 3M Company have NIOSH certification and have different styles and sizes.
Most protective masks will be clearly marked on the outside of the mask, which can be used to identify the model of the export mask, NIOSH certification, and other information.
1) N95-8210
The most common N95 face 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 media technology can enhance the particle capture ability, while reducing breathing resistance, allowing the wearer to breathe more smoothly; the elastic band is welded to make it more durable, and the foam nose pad design makes it more comfortable to wear.
There is also an economical version of N95-8200 with equivalent functions; N95-8210plus, which uses a braided headband that is not easy to pull the hair to make wearing more comfortable; and the same product N95-8110S, which is more suitable for people with small faces.
2) N95-8210V
On the basis of 8210, a 3M Cool Flow breathing valve is added to make breathing (exhalation) easier, keep the face cool and reduce the accumulation of moisture inside the mask. N95 face masks with breathing valves are more comfortable to use in hot and humid environments and are also suitable for situations where masks need to be worn for a long time.
The principle of the one-way breathing valve is that the valve will be opened a little when exhaling to make the air easier to discharge, but when not breathing or inhaling, the valve will automatically seal tightly to maintain the protective effect. As for whether or not to worry about germs entering the open valve when the airflow is exchanged, it is a matter of opinion.
The more interesting CDC FAQ on N95 face masks, about whether medical institutions can use N95 face masks with breathing valves. The CDC believes that N95 face masks can be used when it is not necessary to maintain a sterile environment; however, the breathing valve allows unfiltered air to flow out, which will pollute the sterile environment, so it should not be used in sterile environments such as operating rooms for invasive surgery.
3) N95-8511
