Best of CES: Smart masks, LG rollable phone, flying Cadillac

The technology show CES 2021 had the usual high-tech parade of TVs, laptops, phones and robots, but masks made this year's event different. Here are some of the highlights of CES 2021, which ends on Thursday. AirPop says its masks have the bacterial barrier protection of medical masks but the comfort of consumer masks. The AirPop Active mask with four filters that last for 40 hours each is priced at $149.99. A detachable ventilator regulates airflow and a charging case is lined with a UV light interior to kill bacteria and viruses as the mask charges.
