00:00I know we all use masks according to the availability, but the mask you are using is that really

00:06helpful, is that really effective against this triple mutant COVID-19?

00:10We all know that coronavirus spreads through small droplets.

00:18So according to the ICMR, small droplets can spread up to the 8 feet if you are not wearing

00:25the mask.

00:26But the studies like the Florida Atlantic study says that if you wear gloves or a handkerchief,

00:32then this droplet spread is reduced from 8 feet to the 4 feet.

00:37But this handkerchief is not going to protect you from the COVID-19 virus.

00:47Generally people use this fashionable face mask.

00:51So how do we know if this fashionable mask is really effective or not?

00:56CDC says that the fabric should be of cotton and it can be a single layer, it can be a

01:03double layer or a triple layer.

01:05So the more the layer and the tighter it is, the more protective it is.

01:09So how do we know if it is effective or not?

01:12CDC has shown a light test for this.

01:15If you keep this mask towards the light and if the light is passing through it, it means

01:21that the mask is not effective for you.

01:24CDC also says that the cloth mask should have a nose piece.

01:28In this, mostly the fashionable mask does not have a nose piece.

01:36According to the European General Studies, this surgical mask is three times more effective

01:41than the cloth mask.

01:44People will say that the light also passes through this.

01:47But the reason is that it is more effective because it is made up of non-woven fabric material.

01:54So it is having an electrostatic effect.

01:57So the virus cannot enter inside.

02:00But the drawback regarding this surgical mask is that its lifespan is very short.

02:06It is only 6 hours.

02:07It is just a use and throw mask.

02:09So we cannot use this surgical mask again.

02:12Because after washing it, the non-woven fabric material loses its electrostatic effect.

02:18And now the virus can easily enter into this mask.

02:23According to CDC, this surgical mask can block 57% of the air droplet to enter.

02:29But if there is space in between, the air can come out a little.

02:33So if you do the knotting of this surgical mask like this.

02:37So this can block 77% of the air droplet.

02:47And the best mask is the N95 mask.

02:49And this is the N95 mask.

02:50And to remove the N95 mask or any other mask, we have to hold the ties or the knot.

02:56Not to touch the mask.

02:57Not to touch the front face of the mask.

02:59Like this we have to remove the mask.

03:02Like this we have to remove the mask.

03:05Or to wear this, we have to hold these ties only.

03:08And this is a N95 mask.

03:11But this is having a valve.

03:13The mask which is having a valve is a selfish mask.

03:16Because it is having an expiratory valve.

03:19It protects you from the COVID-19 virus.

03:22But if you are positive, then you are spreading the virus to others.

03:25You are spreading the infections to others.

03:27You can see this expiratory valve.

03:29The air droplets can easily pass out through this.

03:33So this is an easy source of infection.

03:40So the best way in this time is to wear the cloth mask and the surgical mask together.

03:46Double masking means a knotting surgical mask.

03:50And a cloth mask over it can block 87% of the air droplets to enter into it.

03:57By this way you are protecting yourself from the COVID-19 virus as well as the patients.
