Masks are recommended as a clear shield to help prevent breathing droplets from travelling in and out of the air when a person wearing a mask talks, coughs or sneezes. It's called the root control. Interesting point, isn’t it!
This advice is focused on what we know about the role of respiratory droplets in the spread of the virus that causes COVID-19, combined with emerging evidence from clinical and laboratory studies that shows that masks minimize the spraying of droplets when worn over the nose and mouth.
COVID-19 spreads primarily among people who are in close contact with each, so the use of masks is mandatory if you feel that maintain social distancing is going to be an unachievable task. The Centers for Disease Control, also known as CDC have continuously revised their guidelines for the usage of masks and the same are available to people as an actual scientific evidence.

It is very tricky to actually recommend a mask to someone unless you are an expert, since not all masks are rendered equal. The N95 mask for sale effectively prevents the spread of the deadly Corona virus. These masks should be properly fitted and ergonomically sealed according to your facial features to clearly filter out 95% of the 0.3 micron or larger particles. The disadvantage is that these N95 masks are in severe deficiency even for the medical professionals who are exposed to the highest level of COVID19 and stand much ahead of all of us in the line of needing the best defense in this cruel pandemic.
If you feel that you can figure out smart ways to actually match an N95 mask, you are wrong. Hence, the CDC does not recommend them for general use.
Owing to shortages, the CDC also does not recommend surgical masks to the general public. These masks do not seal against the face but have non-woven polypropylene layers that are highly resistant to any amount of moisture around. In a surgical mask, about 70 per cent of the outside air flows through the mask and around 30 per cent passes around the edges, which is exactly why they are not as effective as the N95 masks.
You and your family must follow the following face mask precautions:
1. Don't make an individual wear a mask if he/she is asthmatic or consistently complains of breathing issues or someone who is medically unconscious and will fail to remove the mask without assistance.
2. Do not make your child who is lesser than 2 years old wear a mask.
3. You need to wear your face mask whenever you step out. Do not use it as a replacement for social distancing.
N95 masks are a vital preventive measure and should be made the maximum use of in situations where you will find it hard to maintain social distancing, for example, in a flight, at a conference, etc.
If you land yourself in a situation where you fall short of a mask or cannot use the mask with you because of hygiene issues, ensure that additional steps are taken to minimize the risk of COVID-19 spread, including social distances, regular hand washing, and regular surface cleaning and disinfection.
