Ages after ages, people are using different types of attires. In every era, the design of the attire and fashion kept changing. In the twenty-first century, one of the vital apparel has become a mask. Though a year back, it was not that significant, today it has become one of the primary necessities for human life. Afterward the arrival of the novel Coronavirus, scientists pointed three things as the lifesavers.
The Affordable Mask in the Market
The virus named Corona spreads through contact and inhalation. Generally, when an average person goes nearby a person infected by the following virus, becoming infected with that average person is above ninety percent. Moreover, the cure or vaccine is remaining to discover. Yet, experts disclosed some steps which are much essential to avoid the infection or spread the virus. Wearing a mask on the face can help prevent transmission of the virus, and both classes of people are recommended to wear masks. In the market, according to the budget and uses, there are many mask types available, such as surgical-grade mask, kn95 with valve or without, N95, and many more. In these types, the surgical grade is just for single-use and quite affordable. The N95 is the expensive one and ensures a heavy use. Experts discovered a mask to avoid discrimination and privilege the people with a quality mask that can stop above 95% small particles and budget-friendly, and that mask is kn95.
The mask kn95 consists of 5 layers of protection, which is beyond the expectation of general people. And to breathe more safely, experts added another option on it; that is a pathway by which air can pass through easily called a valve. This convenience has made the kn95 mask more popular.
The Rationale behind Choosing the KN95
There are several reasons to choose this mask. And many tests occurred regarding this type, and the result was satisfactory. Unlike the surgical mask, this mask was developed to use several (3-4) times.
The first layer is made of non-woven fabrics; this layer can filter tremendously and significantly small particles. Generally, it works to purify the dirt and other particles, which are more significant than 0.3 microns. The second one is the electrostatic layer. This layer is made of polymer nano-fibers with the assist of an extraordinary process. This layer can stick to the 0.3 micron-sized particles, and to make it safer, the developers have repeated the same electrostatic coating, and the fourth layer is the cotton layer. Generally, the cotton layer is made of PP Cotton. And at the finishing, another non-woven fabric is there. Both the first and the last non-woven layer are attached by heat and responsible for holding the internal three layers. These layers make a great filtering process indeed, but there is a difficulty that experts have found. That is, since the pressure of air passing is the same from every direction of the mask, during exhalation, it warms up and creates trouble against inhalation. To prevent this issue and make the breathing process more comfortable, experts attached a passage named valve. As a result, the problems are no longer available, and the mask worked more effectively despite having the valve. You can also check ahegao mask.

Neither the time will stop its speed, nor will the world stop moving forward. Nonetheless, we all have to take steps by maintain hygiene factors and guard our bodies to breathe fresh air.
