A major problem with regular plastic masks is the flexibility. It is very easy to stretch the face to the point where air can escape through the nose or mouth openings. Since air leakage through the face causes the face to look worn out quickly, the people that wear these kinds of face masks need a lot of sleep to repair the damage caused by the constant stretching. Plastic is also very lightweight and not very comfortable to wear for long periods of time.
With the use of special composites, the Kn95 masks are able to overcome these two problems. The best part about these is that they can be used for any kind of situation and any level of emergency, from a traumatic brain injury to the civilian population. In fact, these can even be used as a basic surgical mask. The knuts are made of a strong nylon, which provides extra durability and comfort. If you are looking to buy one, the internet will be your best choice to find a wholesale supplier, since these are usually much cheaper than retail prices.
