There are two ways to deal with the masks after use. If the masks are for ordinary use, such as hard surgical masks or ordinary masks carried as usual life or traveling, it is generally sufficient to deal with and clean up and discard them directly as household waste. However, if you go to a place where there is a risk of infection, such as going to the hospital to see a doctor, go to the fever clinic of the hospital or a more dense flow of people, there is a possibility of infected or hidden infected people in the area, or go to the hospital to do a temporary work, inspection, etc., then the masks worn, whether it is a N95 mask or a general medical surgical masks, all need to be discarded as medical waste. At home, you can put the mask in a plastic bag, which can be filled with the appropriate liquid such as water to prevent evaporation from occurring, and use the moisture to adhere to the virus, and then dispose of it after tightening the mouth of the plastic bag. Masks used by hospital staff should be disposed of as medical waste. Source: Dr. Yurai
