steamed mask

Steamed Mask refers to a sterile face mask that has been used to prevent a virus outbreak that has then been steamed in a steamer and re-worn.
Suggested by the all-knowing Ann Chiang, there is no need to buy a new mask for the 2019 nCoV outbreak, you can steam it and it's totally disinfected.

When Ann Chiang mentioned she wore a steamed mask, medical sector lawmaker Pierre Chan said this is simply a "horrible" idea and he appealed to people not to take up the suggestion.
