The LG PuriCare Wearable Air Purifier battery-powered face mask operates similarly to the company’s home air purifier products by using two H13 HEPA filters. This design supplies you with fresh, clean air—whether you’re indoors or outdoors. The LG PuriCare Wearable Air Purifier also features dual fans and a patented respiratory sensor to filter out unclean air. Also, it detects the volume of your breath and adjusts the fan’s speed accordingly. In particular, the fans will automatically increase to assist with air intake. Or, they’ll reduce the resistance when exhaling to make breathing effortless. Most impressively, the UV-LED lights kill harmful germs to keep you healthy. It’s ergonomically designed to fit snugly and minimize air leakage. It’s also comfortable to wear for hours on end. In fact, the battery offers up to eight hours of use.
