Do you know which masks are better for epidemic prevention?

N95 masks, medical surgical masks, and disposable medical masks that meet national standards all have protective functions and meet the requirements of epidemic prevention.
N95, KN95 masks
Medical N95 adds a hydrophobic layer based on the blocking ability of particles, which can prevent liquid splashing, especially when doctors perform intubation and other operations, it can play a more effective protective role. The N95 series masks (N99, 95, 90) have the strongest protective ability, but the air permeability is relatively poor, and they are prone to hypoxia after long-term use. They are suitable for healthy people with high epidemic prevention requirements.
We often see industrial dust masks sold as medical N95 masks on the market, and many people confuse the two. Industrial dust masks are special protection, mainly used to block dust to protect the lungs. The GB2626-2006 standard is implemented in the standard, which requires the filtration efficiency (dust resistance rate) of dust masks, and the particle diameter is less than 5 microns. The dust resistance rate must be greater than 90%, and the dust resistance rate with particle diameter less than 2 microns must be greater than 70%. The common labels KP90, KP95, KP100 are industrial dust masks.
medical surgical mask
Medical surgical masks also have a filter layer and a hydrophobic layer, and the hydrophobic layer can effectively prevent infection from liquid or droplet splashing. However, for the protective filtering ability of particles, the protective ability of medical surgical masks is slightly worse than that of medical N95 masks. For the general population in low-risk areas, the use of medical surgical masks can basically meet the protection needs.
Disposable medical masks are generally made of non-woven fabrics, which can block secretions from the nasal cavity and oral cavity, and can be used for daily protection in low-risk areas. In addition, due to the characteristics of children's skin, respiratory tract and skull structure, there are special children's masks. When you buy, please choose children's masks that meet the standards.
