What Types Of Face Masks Are Effective In Preventing COVID 19?


What Types Of Face Masks Are Effective In Preventing COVID 19?: It is now known that the use of face masks is necessary to protect against coronavirus disease COVID 19.

But what kind of mask can provide more protection from disease?

By the way, N95 is considered the best, but it is more important for medical professionals who live close to patients.

For the general public, cloth masks can also provide considerable protection from COVID 19, but the question is which type of clothing can be more effective?

The answer has now emerged in a new medical study in the United States.

Research from the US National Institute of Standards and Technology found that cotton face masks are more effective against COVID 19.

Several medical organizations, including the World Health Organization, have recommended that people use face masks.


In this new study, the material of this face mask was tested in high humidity conditions which matched the air coming out of the mouth.

Research has shown that face masks made of cotton work better than expected.

The study tested 9 different types of cotton and 6 types of synthetic fabrics, including polyester and rayon, at 99% humidity (so much moisture in our breath) and 55% humidity.

The results showed that cotton was surprisingly effective and that the difference was very clear.

The researchers said that the face masks made of cotton absorb the moisture released by the breath and filter the particles in the air in a better way and thus the risk of cod is significantly reduced.

Research has shown that face masks made of cotton are capable of catching up to 33% of particles, while the performance of other types does not change in moisture.

The researchers tested particles of different sizes in the study and found that after the moisture is absorbed in the cotton, these particles get trapped in the moisture.

In fact, moisture increases the volume of these particles and makes it very difficult for them to pass through the mask.

On the other hand, synthetic masks do not create a humid environment, while medical masks do not change the humidity, however, they are designed to work in all kinds of environments.

Research has shown that the best type of cotton is cotton flannel.

Researchers believe that this type of cotton causes airborne particles to get trapped in the fabric.

However, he also said that this does not mean that wet masks are better, if the masks are wet, they should be replaced.

The good news is that cotton masks can be washed and used many times, which are also environmentally friendly.

The researchers said that although more research is needed in this regard, the results have helped in the search for international quality cloth masks, which can slow down the spread of COVID 19.


The results of the study were published in the medical journal ACS Applied Nanomaterials.
