People use different types of masks to protect themselves from the covid virus, cotton masks are widely used. You can get surgical masks or blue masks that are often found in the market at cheaper rates.

Remember that just wearing a mask does not prevent you from contracting the coronavirus, so you should wear a good and effective mask. The University of Waterloo in Canada conducted a study that reveals some interesting details.

N95 and KN95 masks contain more aerosols than blue masks, which prevents very fine particles from escaping from the mouth or breath.

The blue mask, on the other hand, appeared to be 10% effective in preventing the crown. Professor Sarhi Yarusevich said different masks have different distances to prevent aerosols.

A study by Yarusevich and his team found that many people wear masks that do not match their face. The N95 mask adapts perfectly to the face.

Dress masks can also cause aerosol leaks. It can cause a corona infection in others if you have a corona and if you wear a dress mask.

N95 can filter aerosols over 50%. The rest spreads out and the risk is reduced. This is why doctors wear N95 masks because they are more effective. “We have provided concrete reasons and data in this study,” Yarusevich said.

When you wear a mask, people think about ventilation, that is, breathing problems. However, studies have shown that N95 has good ventilation. It also provides security.

Michael Osterhom, former adviser to US President Joe Biden, said covering the face with a cloth was not very effective, people should wear an N95 mask.

If you are using an N95 mask or three layers, it is not necessary to apply a double mask. Double masking offers more protection and fits better than a single mask. But if it’s N95, you don’t need another mask, says Vivek Nangia, HOD, Max Hospital.
