"Don't let children suffer from haze and viruses, which is the greatest comfort." For the kids. How to choose a mask that suits you In the face of haze and viruses. How to choose masks for children? What is N95? The material determines the filtering performance of the mask, the material is fine enough and the adhesion is strong, the mask can filter smaller particles, the better the protective performance, recently we often hear N95 mask, N95 is the material. This material has a filtering efficiency of more than 95% for particles of a certain size, while other messy masks are much worse, such as Severe Acute Respiratory Syndrome (SARS) in 2003, when cotton gauze masks were worn, no matter how many layers, the filtering effect is still relatively poor. Expand the full text Looking at the table,Medical Disposable Coverall, the filtration efficiency of N95 is about 97.4%, while that of cotton gauze masks is only 30% -40%. It should be noted here that the filtration efficiency of surgical masks is definitely lower than that of N95. However, some articles describe that the protective effect of surgical masks against influenza viruses is no different from that of N95. In fact, it depends on the situation in which they are used. In some scenarios, the final protective effect of surgical masks and N95 may be similar,Against Bacteria Breathable KN95 Face Mask, but this is almost conditional. In many scenarios, surgical masks are not as good as N95, or even far worse than N95. For example, a study published in the International Journal of Virology in 2011 found that the protective effect of N95 on upper respiratory tract infection was significantly better than that of surgical masks. Zhong Nanshan's description of masks It is not necessary to wear N95 mask for prevention. General surgical masks can also prevent most of the viruses stuck to dropleng 97-98% of the filtering efficiency! For a higher level of protection, woobi uses an innovative micro-HEPA high-efficiency filter element with spiral folding design for three-dimensional filtration, which makes the breathing resistance lower and the filtering effect better, so that children can breathe safely and smoothly. Innovative micro HEPA high efficiency filter element It has five layers of filtration and 360 ° deep purification, Antivirus Disposable Mask with CE Certificate ,Medical Quickly Delivery Antivirus Coverall, which can effectively isolate harmful substances such as fine particles carrying viruses and bacteria, mall toolbox at the same time, but also to develop a good habit of storage and organization from an early age. Note: Due to the strong sealing performance of woobi,KN95 Mask with Fast Shipping, when the temperature difference between the inside and outside of the mask is large, a small amount of water in the mask is normal. After use, please clean the silica gel part of the mask in time to ensure cleanliness and hygiene.
