(music) – The problem with
the surgical mask, is that there'' s a lot of void right here. So if you can see that there ' s a huge space, where there'' s
air flow in as well as out. So among the points the CDC has suggested, is you can really double mask. So putting a cotton mask over the top of a surgical mask, enables you to truly type of tamp down those areas that were open. Otherwise, double masking will certainly tighten up the underlying mask. You can see there'' s no void below.( positive songs) Take the mask, put a knot in it, right where air enters the mask. It'' s quite straightforward to do. Put that knot right there and afterwards, if you put that medical mask on now with the knot in, so this is what they call a knotted mask. You placed it on with the knots on it, it will shut up that space that was there prior to I place on that double mask. As well as you can see that'' s a whole lot tighter. There is no space there. Same here. You can even put it in if you require to, yet these with the knot make it so tight that it'' s a wonderful tight fitting mask.So, these are both techniques that CDC has made, a knotted mask or dual covering up to enhance the efficiency of our masks. Pretty very easy to do. (Upbeat songs).
