Which mask is more protective?

 There are roughly three types of masks currently in use, one is medical protective masks, surgical masks and disposable masks. Don't be surprised, N95 does not refer to the name of the mask, but the standard for mask review. Among the three types of masks, medical protective masks basically meet the N95 standard, that is, they can achieve a filtration efficiency of more than 95% for particles with a diameter of more than 0.3 microns. The N95 masks mentioned now refer to medical protective masks. In addition to filtering particulate matter, N95 masks can also filter out droplets, volatile toxic gases and dust in the air. These are the differences between N95 masks and general masks.


  To say that the protective ability of N95 masks is naturally incomparable to the other two kinds of masks. Under the raging situation of COVID-19, it is understandable for everyone to choose N95 masks with stronger protection capabilities. However, the understanding of N95 masks should be more comprehensive. N95 masks are more suitable for medical staff, and it is not recommended for ordinary people to wear them daily.


One of the biggest shortcomings of N95 masks is that they have too good airtightness. Masks with too good airtightness will cause a direct problem, which is that they affect breathing. If they are worn for a long time, breathing will be difficult. Some elderly people may have respiratory problems, which is obviously not suitable for long-term wearing of N95 masks. In addition, N95 masks are also disposable masks. It is recommended to replace them after 4 to 6 hours of use. However, its price is much higher than ordinary masks, and it is not cost-effective in terms of cost performance. It is recommended that large households use masks, or choose disposable medical masks and surgical masks, and leave N95 masks to those who really need help. Surgical masks and disposable medical masks, although not as strong as N95 masks, can prevent the virus from spreading through droplets when used properly. The price is relatively low, and they are suitable for home use.
