Does the blue mask, N95 mask offer protection against COVID-19 virus? Find out the exact truth

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

Remember, just wearing a mask does not prevent you from coronavirus, so you have to wear a good and effective mask. The University of Waterloo in Canada has conducted a study which reveals some interesting details.

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

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

A study by Yarusevich and his team found that many people wear masks that do not fit the face. The N95 mask fits the face perfectly.

Clothing masks can also cause aerosols to leak out. This can cause corona infection in others if you have a corona and if you wear a clothing mask.

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

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

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

If you are using an N95 or a three-ply mask, there is no need to apply a double mask. Double masking gives more protection and it fits better than single mask. But if it's N95, you don't need another mask, says Vivek Nangia, HOD, Max Hospital.
