During the epidemic prevention and control period
Masks have become a necessity for going out
Recently, the State Administration for Market Regulation of defective product management center website released the news, because may not achieve the protective effect, 10,000 masks were recalled.
According to the information on the website of the Defective Product Management Center of the State Administration for Market Regulation, a few days ago, Nantong Haoyi Textile Technology Co., Ltd. took the initiative to report the recall plan to the Jiangsu Provincial Market Supervision and Administration Bureau and the Nantong Municipal Market Supervision and Administration Bureau in accordance with the requirements of the "Interim Provisions on the Administration of Consumer Goods Recalls", and will recall the disposable protective masks manufactured between March 4, 2020 and April 24, 2020, involving a quantity of 200 packs (50 packs).
Disposable protective masks within the scope of this recall, the particle filtration efficiency of masks is low, which may lead to consumers not achieving protective effects when using the product. Nantong Haoyi Textile Technology Co., Ltd. will replace disposable protective masks for customers free of charge to eliminate safety hazards.
furthermore
More and more mask styles are on the market
Some are printed and decorated
Some claim to be able to protect against the sun...
Do these masks have an epidemic prevention function?
What are not suitable for wearing during the pandemic?
And how to distinguish?
Today I will take you to know everything~
Which masks are not suitable for wearing during the pandemic?
The common types of masks on the market mainly include: sunscreen and warmth, decoration, medical and industrial. Among them, sunscreen and decorative masks are not recommended to be worn during the epidemic prevention and control period for the following reasons:
●Sunscreen and thermal masks
Ice silk sunscreen masks can play a certain sun protection effect when worn in places with strong ultraviolet rays. Warm masks can be worn in autumn and winter to keep warm and modify the shape of the face. However, the porosity of these two mask materials is large and cannot protect against viruses.
●Decorative masks
There are many printed and dyed masks that do not meet the production standards of mainland masks on the Internet. These masks need to be purchased with caution and may be potentially harmful.
First, although the appearance of such masks is very similar to that of medical surgical masks, the defense against the virus is not enough, which may cause defense omissions.
Second, such masks are often printed with colored ink, if the color fixing effect is not good, color ink may irritate the facial skin, causing allergies.
Third, some masks will also have aromatic amine dyes, which are decomposition carcinogens and are harmful to health.
Which masks have an epidemic prevention function?
Better results?
N95 type masks, medical surgical masks, disposable medical masks, etc. that meet national standards all have protective functions and meet the requirements of epidemic prevention.
●N95 type masks
Medical N95 masks add 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, which can play a more effective protective role.
N95 series masks (N99, 95, 90) have the strongest protective ability, but the breathability is also relatively poor, and they are prone to hypoxia for long-term use, which is suitable for healthy people with high epidemic prevention requirements.
It is often seen that some merchants sell industrial dust masks as medical N95, and many people confuse the two (the common labels of industrial dust masks are KN90, KN95, KN100, KP90, KP95, KP100).
●Medical surgical masks
Medical surgical masks also have a filter layer and a hydrophobic layer, which can effectively prevent liquid or droplet splash infection. However, for the protective filtration ability of particles, medical surgical masks have slightly worse protective ability than medical N95 masks.
For ordinary people in low-risk areas, the use of medical surgical masks can basically meet the needs of protection.
● Disposable medical masks
Such masks are generally made of non-woven fabrics, which can block the secretion pollution of the nasal cavity and mouth, and the protective ability is weaker than that of medical surgical masks.
● Children's masks
Due to the characteristics of the structure of the skin, respiratory tract and skull of children, there are special children's masks. Please select a children's mask that meets the criteria when purchasing.
How to distinguish whether the mask meets the epidemic prevention standards?
If it is difficult to choose and discern when purchasing

In order to truly prevent the epidemic!
Is "anti-virus mask" reliable? Of course not!
In addition to printed and dyed masks, "antibacterial and antiviral" masks have also attracted much attention.
On April 12, the website of the State Food and Drug Administration released the "antibacterial and antiviral" mask consumption risk tips.
Consumer risk tips point out that medical masks are mainly divided into three categories:
Disposable medical masks
Medical surgical masks
Medical protective masks
Drug regulatory authorities in various countries have supervised and managed medical masks as medical devices to ensure the safety and effectiveness of products. In the mainland, medical masks are registered according to the second class of medical devices. Up to now, the mainland has approved 762 domestic medical protective mask registration certificates, 2489 domestic medical surgical mask registration certificates, and 3219 domestic disposable medical mask registration certificates, providing a strong guarantee for epidemic prevention and control.
At present, the non-medical masks that claim to be "antibacterial and antiviral" appear on the market are generally added through blending, spraying and other ways to add various antibacterial agents, the main additives include nano titanium dioxide, nano silver, quaternary ammonium salt, copper ions / copper oxide, Traditional Chinese medicine extracts, etc. The safety and effectiveness of such products shall be fully studied and verified.
In terms of safety, the risk of long-term inhalation of mask antibacterial agents due to shedding should be assessed; in terms of effectiveness, whether the addition of antibacterial agents affects the filtration effect of masks, and the antibacterial and antiviral effects of antibacterial agents should be verified.
The addition of antimicrobial agents to such mask products introduces new risks when the clinical effectiveness of such mask products is not fully verified. At present, in the pre-market evaluation of medical devices, the risk-benefit ratio of continuous and long-term use of such products is insufficient, and it does not have significant clinical significance.
