Methods for sterilizing masks Facing the shortage of masks, to make the masks available for multiple uses, here are some methods for reusing the masks after sterilization, FYI. Ultraviolet irradiation is difficult to sterilize the three layers of the mask uniformly, and its effect has not yet been determined. Ultraviolet rays should not be irradiated on people, because they can have many negative effects. For an oven, its temperature is difficult to ensure around 60 degrees, and it is difficult to ensure average temperature transmission. It’s easy to stick to the oven, and the sterilization effect is poor. The first and third layers of the three-layer surgical mask are gauze-free, highly hydrophobic and breathable. The second layer inside the three-layer surgical mask has high density, can effectively block particles above 0.1 microns (most virus particles), and also has certain hydrophobic properties.
