What is the best mask, and what is the best mask to use in the near future?

N95 masks work. It is one of 9 types of particulate masks certified by NIOSH. N means that it is not suitable for oily particles (the oil smoke produced by stir-frying is oily particulate matter, and the droplets produced by people talking or coughing are not oily), 95 means that the filtration efficiency reaches 95% under the detection conditions specified in the NIOSH standard.

Precautions. N95 masks are masks with breathing valves, the function of which is to use a mask with a breathing valve to help you feel more comfortable when exhaling in a humid and hot or poorly ventilated or labor-intensive work environment. Hours of use:

Depending on the user's use and environment, the mask should be replaced immediately if it is difficult or uncomfortable to breathe, if the mask is contaminated with foreign objects such as blood stains or droplets, if the user feels that the breathing resistance is increased, or if the mask is damaged.

It is recommended that ordinary citizens do not blindly wear professional protective masks, such as wearing such professional protective masks, it is necessary to be trained, if you do not understand this knowledge, it is best not to wear them at will.

Reminder: Patients with cardiovascular disease should not wear a 3M mask, especially the N95 model, because this mask is a professional anti-virus and has a very thick texture, and it is easy for patients to have difficulty breathing and feel dizzy due to lack of oxygen after wearing it. Only patients who have been definitively diagnosed are required to wear professional masks.

If ordinary citizens wear masks, it is best to choose better breathability.

It is best to use N95 type masks, ordinary masks also have an isolation effect, and they are stronger than nothing. Wear a mask when you go out.

You can use N95 masks to prevent new pneumonia, and if you don't have them, you can use general surgical masks.

If you have money, buy something better and more comfortable to wear.

Ordinary masks are fine, as long as they are changed frequently.

To prevent the epidemic virus, what masks to wear.

Of course it's N95 and medical surgical disposable masks, for me, whatever917, or shop painting, clothes scattered at noon silk silk your noon noon,

Henan Jihe N95 mask is very good.

The GHE N95 mask is an airborne particulate mask, and its requirement is to be able to filter more than 95 percent of non-oily particulate matter. It is mainly used for medical staff in the fever ward of the hospital to avoid viral and bacterial infection, and can achieve secondary protection.

In addition to the higher filtration effect of N95 than medical masks, another feature is that it is designed according to the contour of the human face, and the edge of the mask has a good fit.

How to wear it. If there is a gap between the mask and the face, when a person breathes, the airflow will flow to the gap, and the dust, droplets, aerosols, etc. attached to the virus can enter the body through the gap with the airflow, causing infection.

Therefore, officers and soldiers should standardize the wearing of masks. When wearing the mask, first reserve the curvature of the mask, fix the mask on the face through the ear straps, completely cover the mouth, nose and jaw, and then pinch the metal strip above the bridge of the nose to make it close to the bridge of the nose, and finally adjust the airtightness of the chin area. If necessary, the lanyard can be knotted from the back of the head to improve the tightness.

Avoid touching the outside of the mask with your hands during the entire wearing process.
