Whether it's online or out at the drugstore, there are many places where masks are out of stock. But there are still many people do not know which masks should be brought to be useful, after all, there are disposable medical masks, paper masks, cotton masks, activated charcoal masks and so on on the market, many people can not distinguish

Medical masks, nursing masks, surgical masks, non-surgical masks, what is the difference?

1, the number of layers of different

Medical masks are composed of mask face body and tension band, which mask face body is divided into the inner, middle and outer three layers, ordinary medical masks are common gauze masks, there are four, eight, sixteen layers and other specifications.

2, different protective role

Ordinary masks are used to filter the air into the mouth and nose, in order to block harmful gases, odors, droplets in and out of the wearer's mouth and nose of the appliances.

Medical masks, comfortable, odorless, does not contain glass fiber, non-irritating to the skin, waterproof, and after disinfection can kill or remove pathogenic microorganisms on the medium of transmission to achieve harmlessness; and on the dust, due to small breathing resistance, wear hygiene, will be aerosols, dust, smoke, fumes, droplets, poisonous gases and vapors such as adsorption of the filter material, blocking and not inhaled, effectively isolate the Pollution source.

3. Performance is different:

The three types of masks can have a filtering effect on bacteria, but they are different in waterproof and particle filtration efficiency. First of all, disposable medical masks do not have waterproofness and particle filtration efficiency performance requirements, while medical surgical masks and medical protective masks have requirements. Secondly, the waterproof performance of medical surgical masks is higher than that of medical protective masks, which can prevent the infection of the doctor by the splash of blood and body fluids produced during the operation.

4. Different shapes of masks:

Disposable medical masks and medical surgical masks are rectangular in shape, with ears and straps. And the vast majority of medical protective masks are duckbill-shaped, this is better to distinguish.

Special note:

Medical masks are generally divided into cotton gauze masks, medical surgical masks, N95 masks of three categories, which are characterized by:

1, cotton gauze masks: can prevent some of the viruses from invading, but with the human face is poorly closed, anti-virus efficiency is low.

2, medical surgical masks: divided into three layers, the outer layer of water-blocking, the middle layer of air blocking 5μm particles greater than 90%, the inner layer of moisture absorption.

3, N95 medical protective mask: N95 is the U.S. Occupational Safety and Health Research Institute certification. N refers to non-oil particulate matter, 95 refers to the standard testing conditions under the filter rate of 95%, with a good fit.

After the above introduction to the performance of different masks, combined with the protection we want to achieve the purpose and use of the scene, to give you the following analysis:

When hoping to enter and exit the public **** place without being virus, we need to pay attention to is the particulate filtering of masks and waterproof, anti-flecking performance. Therefore, surgical masks and protective masks are ideal, while ordinary medical masks are difficult to use.

On the choice of the first two, protective masks are the big brother in the industry, but from an economic point of view and wearing comfort, surgical masks have a higher cost-effective. Because we, the public, do not need frequent contact with patients with suspected or high-risk viral infections, as long as we can meet the need for basic protection in public, then the performance of surgical masks is already sufficient.
