What do you mean by non-sterile masks sold in pharmacies?
1. Non-sterilization level means that the cleanliness of the mask is 100%, which is almost the same regardless of the filtering effect.
2. Only the clinical operation is aseptic operation, and sterilization must be used.
3. Disinfection masks are similar to gas masks, which can filter toxic bacteria. Non-disinfection masks are general dust-proof and smog-proof masks. 4. Non-sterilized masks, which have not been sterilized by ethylene oxide, do not need an analysis period of 3- 14 days after production, and can be directly marketed.
4. The average number of unsterilized bacteria per gram is greater than 100 in the Microbiological Inspection Standard for Sterile and Unserilized Medical Masks.
5. The non-sterile type of ethylene oxide sterilization can also play a certain protective role.
The main differences are: first, there is no sterilization, which means that medical masks are just ordinary, and there may be other bacteria on them, which may not necessarily cause disease. If sterilized, the mask is sterile within the validity period of the package, with the nose and mouth facing inward, and the virus isolation is effective when used outside;
As for whether it can prevent viruses, it depends on different types of masks. Secondly, the sterilization source type is similar to a gas mask, which has the function of filtering toxic bacteria, and the non-sterilization type is a general dust-proof and smog-proof mask.
Non-sterile masks are common dust masks, which generally cannot effectively help isolate bacteria and viruses. They are only suitable for general foggy days, dust and strong winds. Therefore, when we buy masks, we should ask clearly or see clearly whether the information on them is what we need.
According to the requirements, medical disposable masks cannot be used in clinic after expiration. But ordinary people really don't have a mask, and this expired mask can be used under the condition that the seal is not completely clean, which is better than not wearing it, but it is not recommended. For the sake of safety, it is recommended to disinfect before processing, or directly replace it with a new product.
What's the difference between medical masks and non-medical masks?
What do you mean by unsterilized?
Medical devices can only be marked as "sterile" when a confirmed sterilization process is used. When this process is not carried out, it must be marked "Not Sterilized".
Aseptic processing means that when a medical device is expected to be sterile and cannot be finally sterilized, aseptic processing is its manufacturing method.
Aseptic processing requirements:
① Sterilize the whole product, and then put it into a sterilization container. After sterilization, the components of the product are further processed and assembled.
③ The products are packaged in aseptic containers, and the processing and packaging are carried out in a way to minimize the N pollution opportunities of the project, and in a controlled environment to keep the particles within the specified limits and minimize personnel intervention.

Is there a difference between medical masks and general masks?
During the period of pneumonia epidemic, if you buy masks carefully in your circle of friends, you will probably buy dust masks, which have no virus protection effect.
How to disinfect an unsterilized medical mask?
If it is too much, it is usually sterilized with ethylene oxide, but ethylene oxide is a carcinogen and is prohibited by non-professionals. If it is less, it is usually ultraviolet radiation, but the ultraviolet penetration ability is poor, and the mask cannot be folded. Sterilized masks should be stored aseptically, otherwise they will be the same as those that have not been sterilized.
Is the double-certified n95 mask sterilized or not?
I also want to know the answer.
Can masks with ineffective sterilization period be used for non-medical purposes?
Masks with ineffective sterilization can be used in non-medical industries, such as outdoor smog prevention, industrial dust prevention and other environments, but if it is judged that the mask has exceeded the shelf life of the manufacturer, it can no longer be used.
Can a non-sterile mask be heated and disinfected with an electric iron?
Yes, high temperature can kill viruses and bacteria, but don't destroy the structure of the mask when using it. You can also use ultraviolet radiation for disinfection for half an hour.
Can I use a disposable mask without sterile bags?
It should work, because it's a one-time cough. When you clean it up and bring it back, throw it away quickly. This cough can work.
