Will schools be using appropriate HEPA filters in the classroom?

posted Aug. 11

APS uses Certified Air Cleaning Devices (CACDs) in classroom spaces. These units are certified by the Association of Home Appliance Manufacturers (AHAM) and the California Air Resource Board (CARB). APS looked for units with high certified clean air delivery rates (CADR) and lower decibel ratings (dB) for teaching spaces.
