Medical face masks are suitable for surgeons, because it can protect doctors from pathogens during surgery. So, in the period of coronavirus and flu, how should we choose the best face mask to protect from coronavirus?
Medical surgical mask
If you have been to a dentist,surgical masks will look familiar-they will be used by doctor and nurse to prevent liquids from splashing. The main purpose of surgical masks is to prevent infected people from sneezing or coughing liquid from entering your mouth or nose. If you are in close contact with someone who is ill, wearing a medical mask can protect the doctor and also prevent the disease from spreading to others.
Can Kn95 reduce the spread of viruses?
The rapid spread of COVID-19 around the world has made us pay more attention to various preventive measures. Make sure to wash your hands frequently, minimize outdoor activities. You must wear a mask when you go out. The outbreak of the epidemic also caused people to doubt the masks. Many people want to know whether the kn95 mask can prevent viruses?
According to the requirements of GB2626 standard, KN standard masks are classified again according to their filtering performance for non-oily particles. We are already familiar with the three masks KN90, KN95 and KN100. The KN95 mask refers to a filtration efficiency of greater than 95% for non-oily particles above 0.075 microns, and the diameter of the new coronavirus COVID-19 is about 0.1 to 0.12 microns. Therefore, wearing a KN95 mask can effectively prevent viruses.
However, here is that qualified masks that meet all the standards of GB2626 have no anti-penetration requirements. The biggest difference between it and medical mask. Medical surgical masks have anti-permeability requirements, and the outermost layer is a waterproof layer. Therefore, care must be taken to avoid patient droplets and saliva in order to prevent the mask from getting wet and increasing the permeability of the virus.
Choose a mask with or without a breathing valve?
No breathing valve mask: two-way breathing protection. Whether it is inhaled or exhaled, it must be filtered by the mask.
Mask with one-way breathing valve: the wearer can only protect himself.
Which of KF94 mask and N95 mask is better?
Since KF94 is not aimed at medical standards, there is no relevant bacterial filtration rate standard in the production process. In addition, the external materials are the same as the non-medical KN95 and N95 masks. Water resistance is not as good as medical masks. Once the droplets are contaminated,if the mask is not replaced for a long time, it will still increase the permeability of bacteria and viruses. Therefore, KF94 can play the role of personal protection, but its effect is inferior to KN95 protective masks.
Is the KF94 mask used only once?
As we all know, KN95 is the Chinese standard for protective masks, which refers to filtering non-oily particles with a diameter greater than 0.3% and greater than 95%. The KF94 mask was developed by Korea. According to the official website of the Korea Food and Drug Administration (MFDS), the standard mask has a filtration rate of more than 94% for particles with a diameter of 0.4 μm.
In other words, the KF94 standard mask can filter out at least 94% of particles with a diameter equal to 0.4 μm.
Therefore, the KF94 mask is not disposable, it is the same type of protective mask as the KN95 mask. If we are no direct contact with new coronavirus-infected people or endemic areas, etc., we can reuse the kf94 mask,but it can be reused up to 5 times.
How to Choose the Right Face Mask to Protect Yourself?
Outdoor activities, such as walking in the park, keep a distance of more than 2 meters with others
Working environment is well ventilated, indoor independent office
Disposable medical mask
Go to supermarkets, shopping malls, elevators and other crowded and sealed places
Gathering work
A medical staff in the general outpatient department and general ward of the hospital
Work in a crowded, mobile and closed place
Police, security, express delivery and other service personnel
Need to take care of patients at home
N95/KN95 or above standard protection mask
Medical staff in emergency department
Epidemic-related testing personnel
For those who closely on conducting epidemiological investigations
Medical protective masks or Disposable Protective Clothing for Medical Use
Medical staff
Confirming or suspecting a patient
Persons who conduct epidemiological investigations on confirmed and suspected cases
How to reuse the masks?
If you are faced with the shortage of masks, you can reuse the masks depending on the possibility of infection.
If there are the following situations, disposable masks should be discarded:
The mask is damaged and deformed;
The mask becomes wet or dirty;
Breathing becomes more difficult.
01 How to remove the mask?
If the mask you take off needs to be used again, you can hang it in a clean, dry and ventilated place or fold it in a clean and breathable paper bag,and ensure that it is stored separately.
02 Can medical masks be cleaned?
It cannot be disinfected with disinfectant, heating, etc.
Do not use alcohol spray or high temperature disinfection
Alcohol and high temperature will cause the outer material of the mask to degenerate to varying degrees, the ability to block droplets and saliva will decrease, and the protection of the mask will be greatly reduced.
03 Do not use UV light disinfection
The material of the filter layer of the mask is a thermoplastic polymer material, which is very sensitive to ultraviolet rays. After receiving ultraviolet radiation, the structure will be destroyed and the filtration performance will be reduced.
