Factors of face mask that affect the efficacy against SARS-CoV-2

 

Face masks are divided into two common categories; Medical face masks and Non-medical face masks. For instance; Medical mask supplier includes Professional-Grade Medical Mask such as N-95 respirators, surgical and non-surgical face masks. On the other hand, Non-medical face masks consist of disposable homemade masks and filtered masks.

Five Factors affect the effectiveness of face masks against SARS-CoV-2.

Size of the respiratory droplets:

It is vital to note that SARS-CoV-2 viral particles are expelled from the respiratory area as relatively large droplets whenever an infected individuals talk coughs, or sneezes, less so by merely breathing. Larger droplets drop to the ground while smaller droplets are usually suspended in the air then evaporate some seconds later, downsizing to smaller harmful droplets of about 5-10 micrometers that can float longer in the air. Therefore, for face masks to be productive, they must filter particles of the sizes mentioned above. Thus, it is essential to consider the type of material used to make the masks and approved for filtering.

Mode of the respiratory droplets expulsion:

Earlier research suggested that the SARS-Cov-2 virus was spread primarily through coughing, but a recent study concluded that talking is also a critical virus transmission mode. The louder you speak, the more respiratory droplets you expelled. Therefore, there is a more viral load transmission and an increased transmitting chance of the SARS-Cov-2 virus. Coughing forces droplets into the air at more substantial force, allowing them to travel out of distances and widening the infectious perimeter around the infested party.

The material of face masks:

The Occupational Safety and Health Administration, the Centers for Disease Control and Prevention, and National Institute for Occupational Safety and Health regulate N95 respirators. The Medical mask supplier tests for fluid resistance, filtration efficiency, flammability, and biocompatibility. Non-medical mask manufacturers made the mask from different materials and designs with or without filter papers. The combination of material, layers, filters, and how tightly the fabric is knit like cotton will affect the face mask’s efficacy.

The fit of face masks:

The masks’ fit is essential to consider for protecting yourself against viruses like COVID-19. It should fit tightly sufficient to create a seal but comfortably to prevent frequent repositioning.

Generally, a face mask is less helpful or counterproductive if it does not cover your nose and mouth. For instance, you wear it down around your neck for extended times or if it is poorly fitting to the point that it wants frequent adjustment, which brings your hands close to your face repeatedly.

The technique used wearing, removing, and reusing disposable face masks: WHO mentions extended use approximately 6 hours, over reuse but in extenuating circumstances, like short supply, face masks can be re-processed, purified, and reused. It will help if you buy a face mask from a leading Medical mask supplier for more prolonged use and safety. Moreover, it is best for you not to use the soiled, wet, or damaged face mask. For a non-medical setting, you should wash your cloth mask frequently for the most effective result.
