A CoVid tsunami is upon us.  N95 and KN95 filtration masks may be in short supply. You’ll want a way to recycle those you have.  To help us do it properly, the engineers at Tufts University distilled the result of 58 studies that look at methods employing heat, chemicals, and UV light and impact on viral decontamination and maintenance of filtration.

 

The best methods were dry heat, 160 degrees for 50 minutes, hydrogen peroxide exposure for 100 minutes on average, or UV exposure for more than 10 minutes.  Each of these drove a more than 3 log reduction in  CoVid concentrations on and in the mask while maintaining mask filtration, fit, fiber resilience and strap fit.
