Which masks are not suitable for wearing during the epidemic?
Common types of masks on the market mainly include: sun protection and warmth, decoration, medical and industrial use. Among them, sun protection and warm and decorative masks are not recommended during the epidemic prevention and control period. The reasons are as follows:
● Sun protection and warm masks
Ice silk sun protection masks can play a certain sun protection effect when wearing in places with strong ultraviolet rays. Wearing warm masks in autumn and winter can keep warm and modify the face shape. However, these two mask materials have a large porosity and cannot defend against viruses.
● Decorative masks
There are many printed and dyed masks that do not meet my country's mask production standards. Masks like need to be purchased with caution, and there may also be potential harm.
First, although this type of mask looks very similar to medical surgical mask , it does not have enough defense ability for viruses, and may cause defense omissions.
Second, this type of mask is often printed with color ink. If the color fixation effect is not good, color ink may irritate the facial skin and cause allergies.

Which masks have epidemic prevention functions? What's better?
N95 masks, medical surgical masks, disposable medical masks , etc., which meet the national standards, all have protective functions and meet epidemic prevention requirements.
● N95 mask
Medical N95 mask has added a hydrophobic layer on the basis of the barrier ability of particles, which can prevent liquid splashing, especially when doctors perform intubation operations such as intubation, which can play a more effective protective role.
N95 series masks (N99, 95, 90) have the strongest protection ability, , but the breathability is also poor, and it is prone to hypoxia for a long time. is suitable for healthy people with high epidemic prevention requirements.

You can often see merchants on the market sell industrial dust-proof masks as medical N95, and Many people also confuse the two (the common labels of industrial dust-proof masks are KN90, KN95, KN100, KP90, KP95, KP100).
● Medical surgical mask
Medical surgical mask also has a filter layer and a hydrophobic layer, which can effectively prevent liquid or droplet splash infection. However, for the protective filtration capacity of particles, medical surgical masks have slightly worse protection capabilities than medical N95 masks.
● Disposable medical masks
This type of mask is generally made of non-woven fabrics, which can block secretions from the nasal cavity and mouth, and its protection ability is weaker than that of medical surgical masks.
● Children's mask
