LG's battery-powered face mask will "make breathing effortless":

Big Tech is here to save us from COVID-19! With every responsible, compassionate person running around with a mask on nowadays, it seems inevitable that the phrase "wearable technology" will soon regularly include overly complicated high-tech face masks. One of the first major tech companies out of the gate with a questionably useful product is LG. The "LG PuriCare Wearable Air Purifier" is a battery-powered face mask that the company says will "supply fresh, clean air indoors and out."

[...] A HEPA filter can stop respiratory particles (so does a normal N95 mask), but LG's press release only says the mask will "take in clean, filtered air"—it doesn't say anything about filtering exhalations.

The mask is out it[sic] the fourth quarter in "select markets," but you should probably just wear a normal, lighter, cheaper, more comfortable mask. Please wear a mask.

Call me crazy, but I don't want lithium batteries that close to my face.

    Most people don't have their cellphone attached to their face. Even then, a lot of people use speaker phone, hands free talking in their car, or bluetooth headsets. The battery in a bluetooth headset is very small. The battery in something designed to pump air for 8 hours, isn't going to be tiny.

    of course it will be tiny. an 18650 will pac 3ah. The fan would use under 1W. That's like 12 hours right there. you are vastly overestimating the power requirements of a tiny fan pulling just enough air to take a breath. I have a USB fan I plug into my 3ah phone. it's big enough to cool my whole face/neck/chest. It uses 2W. A fan in a mask can use 5x less power. This can run on the battery of airpods.

    and btw, if you're so concerned about lithium fires and gas, one would figure you'd research it. those come from fast discharges where the battery heats and expands. Like a phone searching for signal, a laptop compiling, or a vape. So the opposite of a tiny drizzle that takes a day to drain the battery.
