Sewn cotton mask reduce spread of droplets when coughing to about 2.5 inches - while they travel over 3 foot far without a mask.
Single layer masks like the cheap ones you can buy in some shops are not very efficient when it comes to contain droplets.
I'm on a short family break at the moment, but I'm taking preorders of 2 and 3 cotton layer masks. I have non-woven material to add to the 2 cotton layer masks too.
Without a mask, droplets produced during coughing can travel up to 12 feet. With a mask, this distance is reduced to just a few inches.
