Although there is currently some evidence that respirators can be disinfected for reuse, they are not the perfect solution. "We really need to make sure there's enough supplies of masks for health workers," Cowling added. It is the lack of Personal Protective Equipment (PPE) such as the N95 respirator that has led some scientists to find ways to develop alternatives from materials that can be found in hospitals. Another problem with asking the public to wear a mask is the need to give instructions on how to wear it properly. If the mask is not worn properly, the closed area around the mouth and nose can still let the virus slip into the side. A mustache can also affect the effectiveness of a mask because it keeps the mask from closing. The Centers for Disease Control and Prevention (CDC) has published helpful guidelines for anyone with a beard who wants to wear a mask. But there are also simpler alternatives. A recent study, but not peer-reviewed, has found that 3M surgical masks - the type of surgeon worn in the operating room - can remove nearly 75% of particles up to 0.02 in size. micrometer. Although less effective than the N95 respirator, surgical masks can still help reduce the number of inhaled particles. But by cutting a hole in the heel of the sock and wearing it on a mask can improve the ability of the mask and filter up to 90% of particles.
"The surgical mask, unlike the N95 respirator, is designed to fit loose on the face," said Loretta Fernandez, an environmental chemist at Northeastern University, Boston, Massachusetts, one of who participated in this study, said. "This allows the air to find its way around the respirator to reach the breathing area rather than straight through the mask." They found that adding extra nylon on the outside of the mask reduced this. Fernandez and collaborator Amy Mueller, an engineer at Northeastern University, also looked at the effectiveness of various homemade masks. The most effective type uses multiple layers of fabric, although it is still not as effective as N95 masks and surgical masks. However, adding a layer of nylon on top to allow masks to adhere to the face increases the efficiency to the point where some homemade masks can prevent 80% of the particles. Do not wear a facemask. For medical masks, wear the darker face out, the lighter side t inwards, the aluminum clip facing upwards. When wearing must cover both nose and mouth. Do not touch the surface of the respirator with your hand while wearing it. Do not remove masks when communicating, when coughing, sneezing in public.
When removing the mask, only hold the strap by the ear to remove. Do not use dirty masks. For medical masks, use only once and throw them in a safe, covered trash. For fabric masks, wash your face daily with soap for later use
