MINNEAPOLIS (WCCO) — M Health Fairview announced an innovation they hope will ease the strain on personal protective equipment supplies.

They say they are decontaminating N95 masks at the rate of 62 every 45 minutes using a mobile UV tower system. By those rates, they estimate they could decontaminate up to 600 or 700 masks per eight-hour shift.
