During the epidemic, masks have become a necessity when going out.

There are more and more Internet celebrity masks on the market, some with printing and decoration, and some with various colors… These masks have also become the first choice for many people who are looking for high-value masks.

However, do these masks really have anti-epidemic functions? Does the mask you are wearing now meet the epidemic prevention standards? How to distinguish? After reading this article, check it out for yourself!

What are the common masks on the market? Which are not suitable for wearing during the epidemic?

The common types of masks on the market mainly include: sun protection and warmth, decorative, medical and industrial. Among them, sun protection and thermal protection and decorative masks are not recommended to be worn during the epidemic. The reasons are as follows:

Sunscreen and warm masks

Ice silk sunscreen masks sold on the market, or black cotton masks worn by celebrities when they go out on the street belong to this type of masks.

Ice silk masks are light in texture and can be worn in places with very strong ultraviolet rays in summer to play a part of the sun protection effect. Thermal masks are relatively thick and can be worn in autumn and winter to keep warm and modify the face shape.

However, the porosity of these two mask materials is large and cannot defend against viruses.

decorative masks

There are many masks sold on the Internet that do not have the national standard, but have more varieties of printing and dyeing. Such masks need to be purchased with caution, and there may be potential hazards.

First, although the appearance is very similar to that of medical surgical masks, the defense against viruses is not enough, which may lead to omissions in defense.

Second, these masks are often printed with colored inks. If the color fixing effect is not good, the colored inks may irritate the facial skin and cause allergies.

Third, some masks also contain aromatic amine dyes, which are decomposed carcinogenic substances and are harmful to health.

Which masks have anti-epidemic functions? Better results?

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 mask

Medical N95 adds a hydrophobic layer on the basis of 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 on the market, and many people also confuse the two.

Industrial dust masks

It belongs to special protection and is mainly used to block dust to protect the lungs. The GB2626-2006 standard is implemented in the standard, and the filtration efficiency (dust blocking rate) of the dust mask is required. The particle diameter is less than 5 microns. The dust blocking rate must be greater than 90%, and the particle diameter The dust rejection rate of less than 2 microns must be greater than 70%.

The common labels KN90, KN95, KN100, KP90, KP95, KP100 are industrial dust masks. Among them, the KN series is to prevent non-oily dust, and the KP series is to prevent oily dust.

medical surgical mask

There is also a filter layer and a hydrophobic layer, and the hydrophobic layer can effectively prevent infection from liquid or droplets. 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 ordinary people in low-risk areas, the use of medical surgical masks can basically meet the protection needs. N95 masks will have a certain impact on breathing, and they are more suffocating to wear, and are more suitable for protection in high-risk environments.

Disposable medical mask

Generally made of non-woven fabrics, it can block secretions from the nasal cavity and oral cavity. It can be used for daily protection in low-risk areas, and its protective ability is weaker than that of medical surgical masks.

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.

How to tell whether the mask meets the epidemic prevention standard?

The above types of masks are more complicated. If it is difficult to choose and distinguish, there is a very simple way to judge whether the masks meet the epidemic prevention standards. That is to see whether the codes on the mask packaging and printing meet the following standards:

The product registration number will be marked on the outer packaging of medical masks regulated by the medical device license according to regulations. The numbering rule is usually: X device approval + registration year + 264 + number.

The standard code of the five masks that meet the requirements of epidemic prevention is GB19083-2010 The implementation standard for medical surgical masks is YY0469-2011 The implementation standard for disposable medical masks is YY/T0969-2013 The implementation standard for daily protective masks is GB/ The implementation standard of T 32610-2016 children’s masks is GB/T 38880-2020

In addition, people with sensitive skin or respiratory tract should try not to choose colorful masks that are too bright to avoid health risks.
