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.
