LG has introduced the LG PuriCare Wearable Air Purifier, a reusable electronic mask that they claim helps them breathe better and that, according to the company, "solves the dilemma of home-made masks of inconsistent quality and the scarcity of disposable masks." . In the announcement, the company talks about air cleaning, but does not mention that it works against COVID-19, for which it would have to meet certain requirements. Xiaomi has already launched a similar mask, designed to combat pollution.
The operation, according to LG, seems simple. The PuriCare purifies the air, allowing the wearer to take in clean, filtered air while expelling it in the same condition. To do this, the mask has a respiration sensor, two interchangeable high-efficiency H13 HEPA filters (similar to those in vacuum cleaners and purifiers), two fans, and an 820 mAh battery to power the process.
LG ensures that with the built-in battery, the person wearing the purifying mask will be able to use it for up to eight hours with the fans in low mode, and two hours on high, according to use tests carried out with a temperature of 25 degrees. To kill germs that adhere to the mask, there is a cover with ultraviolet LEDs capable of eliminating them when the mask is stored. The case can also charge the mask, and although LG has not mentioned the type of charge for the moment, in an unboxing on YouTube it can be seen that it incorporates an independent USB-C port.
