Some of our thinking How to use Facemask properly. I've found that some people are wearing masks the wrong way around and that affects their ability to capture viruses. Surgical masks are designed to be worn in one direction only. However, it can be difficult to know which way round the face mask should go. Should the blue side face out, or in? I've did my Research. Most Surgical Masks Are Made of Three Layers 1. Outer fluid-repellent layer: Typically colored blue or green, this layer repels fluid, helping to reduce the chance that viruses and bacteria from the air attach to the mask. 2. High efficiency filter middle layer: The middle layer is what does the hard work in capturing viruses and bacteria. Any particles which get past the outside layers are filtered here. 3. Absorbent layer: The inner layer captures and absorbs moisture, reducing the chance of any mucus or bacteria from leaving the mask when the wearer coughs or talks.
