What is face mask?

The mask is a kind of sanitary product, which is generally used to filter the air entering the mouth and nose by wearing it on the mouth and nose, so as to block harmful gases, smells and droplets from entering and leaving the mouth and nose of the wearer. It is made of gauze or paper, etc.

Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, and when working in dust and other polluted environment, wearing masks has a very good effect.

Masks can be divided into air filter masks and air supply masks


1.Series Face mask 

N series: no time limit for protection of non oil suspended particles

R Series: eight hours for protection of non oil and sweat oil suspended particles

P Series: no time limit for the protection of non oil suspension particles and sweat oil suspension particles

Some of the carriers of the particles are oily, and these substances attached to the electrostatic non-woven fabric will reduce the electrical property and make the fine dust penetrate. Therefore, the filter material to prevent the oil-bearing aerosol should be subject to special electrostatic treatment to achieve the purpose of preventing the fine dust. Therefore, each series is divided into three levels: 95%, 99%, 99.97% (referred to as 95, 99, 100), so there are nine categories of filter materials.


2、 EU en149 standard:

Ffp1 type mask: minimum filtering effect 80%

FFP2 mask: minimum filtering effect 94%

Ffp3 type mask: minimum filtering effect 97%


3、 Australian standard as1716

P1: minimum filtering effect 80%

P2: minimum filtering effect 94%


4、 Japanese mol validation standard:

According to the Decree No. 0207006 issued by Japan on February 7, 2005, the standards of dust masks are as follows

5、 Chinese national standard gb6223-86udc614.894:

Except for Japanese standard (0.06-0.1 μ m), all the above inspection standards are tested with particle size of 0.3 μ M,

The detection flow of EU standard is 95L / min, and that of us standard is 85L / min. In China, the suspended particle size for national standard is more than 90% of less than 5 μ m, more than 70% of less than 2 μ m, and the flow rate is 42.5l/min.


The idea of "the worst case" is adopted in the inspection and certification of filter materials, that is, the worst conditions are set up when the laboratory tests are carried out. For example, the calculated diameter of ammoniated sodium salt or DOP oil mist dust particle size of 0.3 μ m in efficiency test represents the size of extremely small particles that are most easily penetrated into the filter material, and represents the breathing volume when engaging in strong physical labor. 


Before the test, the filter material shall be pretreated with high temperature and high humidity, which represents the harsh working environment. All these aims are to test Under such harsh conditions, if the filter material can reach the corresponding efficiency level through detection, then it will be more effective in practical application to protect the health of workers. 


Generally, the anti-virus filter material uses activated carbon or chemically treated activated carbon as the material to filter the toxic gas or vapor through adsorption or chemical reaction without being inhaled. There are many micropores in the internal structure of activated carbon which can form a large specific surface area. These micropores can inhale toxic vapor and gas molecules with different molecular sizes without escaping. 


The requirements for the treatment and installation of the activated carbon are very high. If the treatment is improper or the activated carbon particles are very thick, resulting in the gap between the particles, then the toxic gas will penetrate into the respiratory tract from the gap, and will not be absorbed. 


Therefore, it is very unscientific to change the activated carbon in bags. The activated carbon in a good chemical filter box should be packed tightly, with small particle size and large specific surface area, so that the anti-virus time will be long, and at the same time, the respiratory resistance should be small and the wearing should be comfortable.


6.How to get face mask from china?

1.Get the real agent or factory from China.Now in China it has around 400 factories with the govermental certificates to manufacture the face mask.

2.Inspect their certificates from the govermental or official website or send the third party to inspect for you if for the big purchase.

3.Ask for the importing certificates from your local goverment.

4.Place a sample for testing the quality with their certificates.

5.Start the real order purchasing with the famous carrier with the full documents.


7. What we can do for you?

We have our own face mask factory with the official certificates CE +FDA.

We have sent the face masks to USA UK,CANADA,GERMANY,FRANCE.....already with the great experience.
