What Make an N95 mask for COVID -19?

An N95 mask is designed to reduce the effects of any allergy which airborne allergens could cause. What makes an N95 mask so important is that they are available in various shapes, sizes, and configurations. For example, there are designed to fit over glasses, while others can be worn over the top of a full-face helmet.

The design of the mask will also depend on the severity of the allergy itself. If you have hay fever, your mask needs to have a higher tensile strength than a milder case. It is also necessary to make sure it does not slip on your face when exercising or walking around. This means that they also come with Velcro straps which should be included if you buy a good one.

You've also heard that N95 masks are in short supply for health-care workers dealing with the COVID-19 coronavirus pandemic. The scarcity has prompted several well-intentioned individuals to make homemade cloth masks that aren't quite official N95 masks.

However, masks made of all this material will not sufficiently shield physicians, nurses, and other health-care workers who deal directly with COVID-19-infected patients. Jersey material lacks the properties needed to filter out too tiny virus particles.

In reality, any handcrafted efforts should bear in mind the eight qualities that an N95 mask or the equivalent possesses -:

1.The Mask Should Filter out the Viral Particles -

The N95 mask shows from its effectiveness in its name

N- represents the number of particles

95- 95% filtering efficiency of the mask.

This means it can filter out the 0.1-micron particles from small to big size like a watermelon. The mechanism of filtering out the particle is different between small particles and large particles.

So, the mask's primary work is to keep away the particles from your nose and mouth.

The High filtering mask is made up of Polypropylene. The particle should go from a smooth to a rough part of the mask for filtering the small particles.

2. The Mask should contain at least Two filtering Mechanism -

The mask should contain more than a filtration mechanism because if one tool stops working, other mechanisms will protect the user. Based on the same concept where we say open try key in many locks, at least one will open.

There are three mechanisms in the N95 mask for filtration -

• Inertial impaction,

• Diffusion, and

• Electrostatic attraction.

The term "inertial impaction" conjures up images of a musical number or a medical operation. However, when the laborious path makes it impossible for particles 1 micron and larger to proceed on their straight paths, it is considered a problem. Such particles are too big to thread through the mask fibers, and they end up catching on one of them.

Diffusion, the second process, prevents particles smaller than 0.1 m from moving forward. The mask filter's layout allows these tiny particles to travel in random directions, colliding with each other and filter fibers. It's less likely that these particles will get through the maze if they're bouncing against each other like they're in a mosh pit.

The third Electrostatic Attraction sounds like a friendly conversation. This type of filtration mechanism blocks the particle's viral particle or any other small particles.

3.The mask should easy to Breath -

Mask must be easy to Breath. as we have to wear a mask for a long duration and some respiratory illness, people also wear a mask, so if the mask does not provide easy to Breath, it is not applicable to wear the mask for a long duration.

The material that should use in the making mask must be comfortable to wear and easy to breathe.

4.The mask should be Seal Fit -

The N95mask provides a snug fit as it makes it more effective than others. You should make the mask a snug fit if you are making a substitute for an N95 mask. With a snug fit, it gives comfort to the user.

5.The mask Should be Durable -

Durability is one of the crucial factors of the mask. If the mask is not durable, then no one will prefer the mask to buy. So, use high-quality material and make it stable. Also, give a guideline to wear a mask.

Conclusion:

As we face a lack of N95 masks in the market, making a homemade fabric mask is one thing in the trend. Above, we have mentioned some items which we should consider before making a homemade N95 mask.

If you don’t have an N95 mask, you can use the Surgical mask and fabric mask. But never step out without wearing a mask. Except wearing a mask, you should Boost your Immune System, Eat Healthy food, wash your hands or sanitize your hands. Stay Safe!
