Korean electronics giant LG has adapted its home air purifying technology into a battery-powered, air purifying face mask with twin H13 HEPA filters, multi-speed fans and a UV-LED sterilizing case. But there's still a lot we don't know.

The PuriCare Wearable Air Purifier, as LG is calling it, appears quite a remarkable device. It straps to the face with straps behind the ears like a regular face mask, but carries an 820-mAh battery to run an active air filtration and purification system for up to eight hours on low mode and two hours on high.

The wearer breathes in and out through a pair of replaceable HEPA filters, with fans to help pull fresh air in from the outside. A "respiratory sensor" controls the speed of these fans, which speed up to assist as you breathe in and slow down to make it easier to breathe out.

When you take it off, you pop it in a charging case flooded with UV-LED lighting that "kills harmful germs" as it charges. LG says it's "ergonomically designed based on extensive facial shape analysis" to "minimize air leakage around the nose and chin," and every component is replaceable and recyclable – right down to the straps.

Here's what we don't know, though. Does it effectively block COVID-19 infection? Does it effectively filter a COVID-19-infected wearer's exhalations so they don't infect others? How much does this thing weigh when strapped to your face? Can anyone hear you when you talk through it? The Verge put further questions to LG, but the company is declining to comment until it has completed certification and testing.

There is currently no information on pricing, but LG will supply more details as part of its IFA 2020 virtual exhibition and says the PuriCare mask will be available in Q4 "in select markets."

You've got the right idea, LG, but I'm looking for something with a little more authority; something that strikes fear my enemies. Something more like this: https://cdn.thedigitalwise.com/wp-content/uploads/2019/09/5593ea68f78e12ecb40c94607173824c.jpg

Fans spinning next to face may lead to a close shave,

A DIY cloth mask would cost you nothing,and protect those around you. All you need is something to stop your infected coughs and sneezes from getting into the air.

That thing is going to pull people's ears right off in its current configuration. There's a reason most big respirators have head straps.

Will it come with a neck brace?

I need one. I thought of using UV light inside the mask but perhaps this design is even better as it takes a short time for the UV to destroy viruses. The ear straps should be replaced by straps going around the back of the head. Personally, I have attached rubber bands on the back of my masks so that my ears do not take the pressure.

Looks a lot like the feedbag for oats I used to have for my horse.

If everyone wore these in public the virus would be dead in a month. I've built my own and it protects from getting the virus far better than a mask. And personally I care more about me than others with 4 risk factors.
HEPA fiilters are rated virus safe.

like pretty much every commercially available mask, none is guaranteed to stop SARS-CoV-2 (0.05-0.15 micron; average 0.1), or most viruses. But just to reduce, more or less significantly, the chance they will go through.
A H13 HEPA filter is supposed to block up to 99.95% of 0.1 (more like 0.3-0.5) micron particles per liter of air. A N95 mask is supposed to block up to 95% of >=0.3 micron particles. A FFP3 mask up to 99% of >=0.3 micron particles.
BTW, the legendary bioweapon Tesla filter is a .... myth. It is highly unlikely (cost wise) they use a HEPA grade filter even close to the above specs. And indeed, their "proof" test was to block most PM2.5 particles, that is 2.5 microns or >20 times bigger than most viruses
