There are more and more net red masks on the market. Some masks are printed and decorated, and some masks use a variety of colors... These masks have also become the election of many people who pursue masks with high face value. However, which masks have epidemic prevention functions?

N95 respirators, medical surgical masks and disposable medical masks that meet the national standards have protective functions and meet the epidemic prevention requirements.

N95 respirator

The medical N95 adds a hydrophobic layer on the basis of the particle blocking ability, which can prevent liquid splashing. It can play a protective role when doctors perform intubation and other operations.

N95 series masks (N99, 95, 90) have strong protection ability, but poor air permeability. They are easy to suffer from oxygen deficiency after long-term use, and are suitable for healthy people with high epidemic prevention requirements.

We often see that industrial dust-proof masks are sold on the market as medical N95, and many people confuse the two.

Industrial dust-proof respirators belong to special protection and are mainly used to prevent dust from protecting the lungs. The standard is in accordance with GB2626-2006. It requires that the filtering efficiency (dust resistance rate) of dust-proof respirators. The dust resistance rate must be greater than 90% if the particle diameter is less than 5 microns, and greater than 70% if the particle diameter is less than 2 microns.

The common labels of KN90, KN95, KN100, KP90, KP95 and KP100 are industrial dust masks. KN series is used to prevent non oily dust, while KP series is used to prevent oily dust.

surgical mask 

There is also a filter layer and a hydrophobic layer, which can prevent the liquid or droplets from splashing and infecting. However, the protective filtering ability of the medical surgical mask is slightly worse than that of the medical N95 mask.

For the general population in low-risk areas, the use of medical surgical masks can basically meet the protection needs. N95 masks have some effects on respiration, and are relatively stifling to wear, which is suitable for the protection of high-risk environments.

Disposable medical mask

It is generally made of non-woven fabric, which can prevent nasal and oral secretions from polluting, and can be used for daily protection in low-risk areas. The protection ability is weaker than medical surgical masks.

In addition, due to the characteristics of children's skin, respiratory tract and skull structure, there are child masks. When purchasing, please choose a child mask that meets the standard.

How to identify whether masks meet epidemic prevention standards?

The above types of masks are complex. If it is difficult to choose and identify them, there is a simple way to judge whether the masks meet the epidemic prevention standards, that is, whether the codes on the mask packaging and printing meet the following standards:

The product registration number will be marked on the outer package of the medical mask subject to the approval and supervision of medical devices according to the regulations, and the numbering rule is generally: X machine registration+registration year+264+number.
