It is not recommended to buy N95 ··

Looks huge....It's actually very light, it feels like a toy, the plastic feeling is strong, and the display screen is large, but because of this, the words displayed in the near look will be a little blurry, and the buttons on it are big...It is not easy to press. I feel that if you are a student, it is better to buy the N85, which is a business jet, and I feel that there is no N85 overall.

It's outdated, it's not easy to use, it's big, it's like a brick.

N95 is disposable.

The use time is 6-8 hours, if under the condition of absolute lack of material, N95 masks can be used repeatedly, through ozone disinfection, boiling water disinfection, ultraviolet disinfection and other different ways to kill viruses, bacteria and other pathogens on the mask, can be used repeatedly, but its anti-virus effect will be reduced a lot.

When using N95 masks, care should be taken to keep a distance of more than 1 meter from other people, especially those with suspected infection. The N95 mask should not be used more than 3 times.

Choice of masks:

1. The selection of appropriate mask varieties should be the first choice of medical workers, and the ordinary absorbent gauze mask should be the first choice for ordinary citizens in their daily life. In special occasions, such as medical treatment and visiting patients, it is advisable for the general public to also choose medical masks.

2. When choosing a qualified mask, it is necessary to see whether there is a trade name on the package, whether there is information about the manufacturer or supplier, and whether there is a mask certificate or instructions for use. Disposable masks should also have disposable labels, and the sterilization method should be indicated for reused medical protective masks.

3. Don't forget to check the appearance when choosing a mask, this is a problem that is easy to ignore when choosing a mask, first of all, check whether the packaging of the mask is complete and whether it is damaged. There must be no holes or stains on the surface of the mask. Medical respirators should not have an exhalation valve.

N95 masks are valid for three years.

If the package is not opened within 3 years, it can be used without damage, and once the expiration date of the mask has passed, it is not recommended to continue to use it. Because the filtration efficiency and protective performance of the filter material will be reduced, the use of expired medical masks cannot effectively block the infection of viral germs. Before using a medical mask, be sure to confirm the date of manufacture and expiration date.

N95 masks are also disposable masks, generally with 3 5 days should be changed, N95 masks than other ordinary masks are more tightly closed, more preventive, so we usually have to bring more N95 masks, especially when gathering in crowded places, we must pay attention, so as to prevent many diseases.

Introduction to N95 masks.

The N95 mask is one of the nine types of anti-particulate masks certified by the National Institute for Occupational Safety and Health, and N means that it is not suitable for oily particles (the oil smoke produced by stir-frying is the oily particulate matter, and the droplets produced by people talking or coughing are not oily); 95 refers to a filtration efficiency of 95% under the detection conditions specified in the NIOSH standard.

The mask is often used for occupational respiratory protection, including certain microbial particles, such as viruses, bacteria, molds, etc., and the biggest feature is that it can prevent droplet infection caused by splashing of patients' body fluids or blood.
