The government has set several standards to avoid coronavirus. Taking full care of cleanliness, social distancing, etc. But in all these, if you go out at the moment, wearing a mask is the most important job. The first step to avoid Covid 19 is to get out wearing a face mask. Centers for Disease Control and Prevention and many health centers are also making people aware of this. Whenever you go out, do wear a face mask.
The mask that comes with the respirator has been considered the most safe. These seals are made of tested respirator fibers, which are most effective in filtering the air. However, the respirator present in the mask must meet the standards stated by the National Institute of Occupational Safety and Health. Certified N95 aspirators can filter up to 95 percent of the particles. N99 Respirators can filter these particles up to 99 percent. N100 aspirators can filter these particles up to 99.7 percent. Some of these aspirators have valves, which are good for breathing.
There are many types of surgical masks available in the market. Most surgical masks are for one-time use. If you use a surgical mask, put it in a closed compartment dustbin only after one use. Filtrations are not standardized in these masks, like respirators. Surgical masks can be 10 to 90 percent safe. However, it is not said to be as safe as a respirator.
DIY i.e. homemade masks are also encouraged by the government. However, its effect is slightly reduced to protect against viruses such as corona. This is because the homemade mask has a nose, cheek, and jaw and a gap between the mask. This puts the risk of small droplets getting into the mask. The quality of homemade masks also depends on which cloth the mask is made from. Although homemade masks are not as effective as medical masks, wearing a mask is a much better option than wearing a mask. Wearing them properly and making them with good clothes can be quite a defense.
