LG appears to have just the ticket for health protection and virus-based-anxiety relief: the PuriCare Wearable Air Purifier.
The face mask air purifier is outfitted with a pair of H13-level HEPA filters, which can remove 99.95% of particles as small as a tenth of a micron in diameter from airflow. For reference, the SARS-CoV-2 virus is about 0.125 microns in diameter.
The wearable purifier also features a charging and storage case with a UV-LED light source that burns away the little nasties, and it is designed to be as close to a universal fit as possible to keep air leakage to a minimum. Its rechargeable batteries can run for up to eight hours.
To facilitate easier breathing, the PuriCare Wearable Air Purifier also sports a couple of small fans, which are controlled by a special sensor that measures your respiration and compensates in kind.
