(CNN Business)When students at Queen’s Grant High School in Matthews, North Carolina, return to class in late August, they’ll notice a purple glow emanating from the vents as they walk down thehallway. The charter school has installed UV lights into its HVAC systems as part of an effort to eliminate viruses and other bacteria in the air.

“We rely on the student population coming in to stay open, so it was important to do everything we can to make sure our students are and feel safe,” said Queen’s Grant High School principal Josh Swartzlander, who said the school will also require students and teachers to wear protective gear. “We enrolled 20 new students right after we made the announcement.”
