Which is better, sterile grade or sterilized grade masks

The biggest difference between sterile and sterilizable disposable masks is the use, sterilized masks are made in strict accordance with the process and sterilized, so sterilized masks are mainly used for medical staff. The use of sterile masks is more extensive, and ordinary people can use this sterile mask.

Secondly, their protective effects are also different, although sterile masks and sterilized masks can protect some bacteria and particles, but the efficacy of sterilized masks will be better. Because sterilized masks can block some of the splashed liquids such as blood, body fluids, and secretions in the air, sterilized masks have a relatively better protective effect. There is also a difference between the two, the ** of sterile masks is slightly lower than that of sterilized masks.

There is not much difference between the two. There is no big difference between sterile masks and sterilized masks, but there is a slight difference in the name, they are all bacteria-free masks made by sterilization procedures, composed of 2 layers of non-woven fabric and 1 layer of filtration, which can block particles such as droplets and dust from the outside world, which can prevent respiratory virus infection to a certain extent, and have a certain protective effect.

The differences between the sterilized and sterile types of masks are as follows:

1. Difference in use: Sterilized masks are made in strict accordance with the process and sterilized, mainly used for medical staff. Sterile masks are more widely used and are used by everyone.

2. The difference in protective effect: sterile masks and sterilized masks can protect some bacteria and particles, and sterilized masks have better efficacy. Sterilized masks can block some of the splashed liquids such as blood, body fluids and secretions in the air, and sterilized masks have a better protective effect.

3. The difference: Sterile masks are slightly lower.

The difference between ordinary masks and medical masks:

Masks are divided into medical masks and non-medical masks, and non-medical masks are ordinary masks; Among them, medical masks can be divided into medical protective masks, medical surgical masks, and ordinary medical masks; Ordinary masks are cotton masks used in daily life, cotton masks can be washed and used repeatedly, but they are easy to cause contamination or bacterial infection and are unhygienic.

Secondly, medical masks are mostly made of one or more layers of non-woven fabrics, and the main production processes include meltblown, spunbond, hot air or acupuncture, etc., which have the equivalent effect of resisting liquids, filtering particles and bacteria, and are a kind of medical protective textiles. The inner layer is skin-friendly ordinary sanitary gauze or non-woven fabric, the middle layer is the isolation filter layer, the ultra-fine polypropylene fiber meltblown material layer, the outer layer is the special material antibacterial layer, and the non-woven fabric or ultra-thin polypropylene meltblown material layer.

Ordinary masks have no protective effect on haze, and can easily lead to pollution or bacterial infection after repeated use; Secondly, most of the printing and dyeing materials in ordinary masks contain heavy metals that are harmful to the human body, and it is not recommended to use them for a long time.

Hello, glad to answer for you! Sterilization-grade masks are good. The production process of non-sterilized masks and sterilized masks is the same, but there are more sterilization steps after the sterilization of sterilized masks, and most of them are sterilized with ethylene oxide.

Non-sterilized masks are also tested at the factory and must meet microbial control indicators. For example, coliforms, Pseudomonas aeruginosa, Staphylococcus aureus, hemolytic streptococcus and fungi should not be detected, which can be understood as allowing some bacteria, but it should be within a controllable range. It can be used directly, and there is no need to take sterilization measures, and sterilization measures cannot be done by the general population, and professional equipment is required.

In terms of composition, it is made of more than three layers of non-woven fabric, which has been sterilized and does not contain bacteria and other microorganisms. In terms of protection, disposable sterile masks can prevent respiratory infections to a certain extent, but they cannot play a role in preventing haze. In addition, in terms of the number of uses, disposable sterile masks cannot be used for a long time, and the use time should not exceed 6 hours.

Summary. Hello dear, which is better, medical mask or sterilization grade mask.

Which is better, medical mask or sterilization grade mask.

Hello dear, which is better, medical mask or sterilization grade mask.

Hello dear, the medical-grade safety factor is relatively high, and the resistance to bacteria and viruses is strong, which can be used to prevent influenza. The sterilization grade mainly refers to the sterilized grade, while the non-sterilization grade refers to the one that has not been sterilized, and there may be other bacteria on it after production, and the protective effect is relatively poor.

Whether it is sterilized or non-sterilized, medical masks have the effect of preventing bacteria and viruses, but the protective effect of medical sterilized masks will be better, mainly because medical sterilized masks have better production requirements, need to be sterilized by ethylene oxide, and it takes 3-14 days of analysis period after production before they can be put on sale, and the inspection standards and requirements are more stringent.

The common disposable masks on the market are divided according to the type of sterilization, which can be divided into sterilized type and non-sterilized type.

What is the difference between non-sterilized and sterilized types? It can be mainly grouped into the following three points:

1.The requirements for microbial indicators are different: the sterilization type requires sterility (microorganisms shall not be detected); The non-sterilized type should be disinfected and sterilized, and it is required that no pathogenic bacteria should be detected, and its detection standards only have limited requirements for microorganisms, and there is no need to achieve the index of sterility.

2.The degree of sterilization and standards are different: the mask workshop for making sterilization must require a 100,000-level purification workshop, and there must be terminal disinfection, such as ethylene oxide or radiation disinfection; The non-sterilized type only needs a clean room, but it is only recommended to disinfect with ethylene oxide.

3.Different environments: Sterilized masks are mainly suitable for ICUs, operating rooms, and other places where the microbiological environment needs to be strictly controlled, while non-sterilized masks can meet daily protection needs.

Hope to answer your questions, hope

1. Non-sterilized masks indicate that medical masks are sterilized by ethylene oxide, which can also play a certain protective role. The sterilization grade of medical masks means that the masks have undergone strict disinfection and sterilization treatment before leaving the factory, so the safety and hygiene of the masks are higher, so the protective function is better.

2. The degree and standard of sterilization of sterilized masks are much greater than those of non-sterilized masks, and the sterility level of the production workshop is much higher than that of non-sterilized masks. The non-sterilized type is basically produced in a dust-free workshop.

Medical masks are non-sterilized, which means that there may be other bacteria on them after the medical mask is produced. If it is sterilized, the mask is sterile within the validity period of the package, and when it is used, it is effective to face the mouth and nose inside, and isolate the virus outside, as for whether it can prevent viruses, it depends on the different types of masks. Secondly, the appearance of the sterilized mask is similar to that of a gas mask that filters poisonous gas bacteria, while the non-sterilized mask is a general dust and haze mask.

Hello: Sterilized masks refer to masks that have undergone disinfection and sterilization treatment for about 7 days before leaving the factory.

A non-sterilized mask is just an ordinary dust mask.

Masks do not need to be sterilized, and all masks are disposable.

If it is more than 6 hours or there is secretion contamination, change the mask in time. Especially during the period of high incidence of pneumonia in the new building, do not use the mask repeatedly, as this will not achieve the effect of preventing the new coronavirus.

Especially in confined spaces and environments with a large number of people, it is necessary to wear masks with a relatively high level of protection, such as N95 masks, or medical surgical masks to effectively prevent the infection of the new coronavirus. During this period, you should go out as little as possible, and remember to wear a mask when you go out to prevent the infection of the virus.

Precautions for the use of masks:

1. Do not share a mask with others.

2. After use, if the mask is intended to be reused, it should not be stored in an airtight bag, and the inside of the mask (on the side of the face) should be avoided from being contaminated during storage.

3. Conventional disinfection and sterilization methods usually damage 3M protective masks.

4. Longitudinally folded masks (such as 3m 9001) should be folded with fingers on the inside of the nose clip to bend the nose clip to avoid the nose clip breaking after repeated bending.

5. In the case of using the original packaging and proper storage, the shelf life of unused 3M masks is generally 3 to 5 years.
