Frankly, the most surprising thing about PuriCare is that more tech companies haven't launched a similar product in the past few months. LG is showing it at the upcoming IFA press conference in Berlin – although the company has opted for a virtual presence at this year's fair.
There is a lot going on in the "Portable Air Purifier" press release. As they say: “LG PuriCare Wearable Air Purifier solves the dilemma that homemade masks are of inconsistent quality and disposal masks are in short supply. The PuriCare portable air purifier uses two H13 HEPA filters, similar to the filters used in the company's home air purifier products. "
The company is apparently doing everything it can not to mention COVID-19. Because certain health-related claims are often subject to different regulations. It is of course true that masks were in short supply in various places during the pandemic. And that was probably the case when LG really started pushing the idea in earnest.
However, it is also worth noting that even professionally made masks offer a fairly wide range of effectiveness against transmission of the virus. There are many questions here. For starters, the filter and how effective it could potentially be for both the wearer and the people around him. After all, the latter is the real argument in favor of wearing masks – to protect those around you.
LG's answer to the COVID-19 question is postponing a possible future approval. "We're waiting for more testing to finish before we can share all the details." Hopefully we'll get more specific answers before it goes on sale in "fourth quarter in select markets". While there are certainly non-coronavirus-related reasons for wearing a mask, including pollution and other pollution.
It's also worth asking what happens when the battery runs out. According to LG, the mask can be operated for eight hours at "low" and two hours at "high" thanks to an integrated 820 mAh battery. But something happens. Sometimes you'll be out and about longer than expected or just forget to fully charge it before leaving the house.
There are two H13 HEPA filters on board, which are similar to the type the company uses for its in-home air filtration system. There are also UV LED lights that are supposed to kill bacteria – additional protection that goes beyond the filter system. In addition to the above-mentioned home filtration systems, LG also produces UV light sticks for disinfection. The company has already worked on many of these things and clearly saw an opportunity to capitalize on them in mask form.
There's quite a bit of on-board technology, including the ability to regulate the rate of filtration based on the wearer's breath. Overkill? Pretty sure. It might also be awkward from the look of the pictures. And then there is the still unknown price.
