The difference Between
Civilian Disposable Masks &
Medical Disposable Masks
Why can’t civilian / common disposable masks be anti-virus?
Civil masks do not meet effective bacterial filtration efficiency indicators, and there are no clear production standards. Production materials can be cotton, dust-free paper, ordinary non-woven fabrics, polyurethane foam, etc.
What affects the filtering efficiency of civilian masks is its material. Regardless of whether it is a general medical mask, a surgical medical mask or a medical protective mask, the material that plays the role of isolation is actually one type: 【melt-blown cloth】, while 【civilian masks do not have melt-blown cloth】.
Even if some civilian masks use meltblown cloth in the middle layer, they have not been professionally 【Electret treatment】 and cannot effectively prevent viruses.
Glossary:
【Melt-blown cloth】
Melt-blown non-woven fabric is a kind of ultra-fine fiber non-woven fabric with a fiber fineness of 0.5-1.0um. The random distribution of the fibers provides a larger surface area between the fibers and the product has a low resistance. High filtration efficiency. Material: PP.
【Electret treatment】
If melt-blown cloth is placed in a high-voltage electrostatic generator, a large number of positive and negative ions will be released between the positive and negative electrode tips, forming a strong electrostatic field on the surface of the material. This is called 【electret processing】.
N95 and medical masks both use the middle 【static】layer to achieve the effect of filtering pm2.5, and the static electricity will directly affect the filtering efficiency.
【The more static electricity, the better the filtration and purification effect. 】
2.How to distinguish between civilian disposable masks and medical disposable masks?
A
The number of layers
Looking at the number of layers, one or two layers of masks
must not be medical standards.
B
The middle layer
If it is three layers: see if the middle layer is ordinary non- woven or meltblown. If ordinary non-woven fabric is used in the middle, it is invalid.
1、Meltblown cloth is a very fine long-fiber non-woven fabric with low strength, easy to tear, and a crisp sound when tearing. 2、Looking at a small piece of meltblown cloth facing the light, you can see the fiber texture. If the uneven thickness of the fiber is very serious, it means that the quality of the meltblown cloth is poor. 3、Cut out a meltblown cloth and use your fingers to get close to the meltblown cloth. The meltblown cloth will tend to stick to your fingers.
In the middle is ordinary non-woven fabric:
Electrostatic meltblown cloth in the middle: very delicate, barely visible holes
Two comparison charts: meltblown cloth on the left and ordinary non-woven cloth on the right
C
The packaging
Are there any specific product names of medical masks such as “medical protective masks”, “medical surgical masks” and “disposable medical masks” on the package?
According to the requirements of medical device regulations for packaging information, regular medical mask packaging will have information such as the production license number, product registration certificate number, technical requirement number, and product manual.
D
The ear-band
See if the welding point of the ear band is firm. Pull the ear band by hand. If the ear band is not welded firmly, it will break.
E
The standards ( take Chinese standards as an example )
The production standard of disposable medical masks in China is: YY / T 0969-2013
If the package says: YZB standard, it proves that it is a custom-made standard for the enterprise, then you can go to the website of the China State Food and Drug Administration to check. If it is found that it meets the standard of disposable medical masks (see structure and application scope) Can also be purchased.
RECOMMENDATION
It is recommended that you make a judgment when purchasing a mask according to the medical mask production standards of the country where it is produced.
We can guarantee that the disposable medical masks you purchase from ArcBro meet the Chinese national standards.
