LG battery-powered mask, setting to two hours on high

 LG battery-powered mask, setting to two hours on high.

LG on Thursday announced an air-purifying face mask, which the company plans to show off at next week's IFA trade show in Berlin. The face mask will fit like many others, with loops that hook behind the ears, but LG said it'll include two high-quality HEPA filters that can remove at least 99.97% of particulates in the air down to .3 microns in size. 

In a world continuing to face the coronavirus pandemic, an air-purifying mask seems likely to gain traction. While the price and release date haven't been announced, LG offered other information about the device.
