High-tech mask to give users own supply of filtered air

Battery-powered units to make breathing ‘effortless’ and prevent any infected droplets being inhaled

A TECHNOLOGY firm has invented a battery-powered face mask fitted with mini air-conditioning units to give users their own personal supply of filtered air, making it easier to breathe. Fitted with gadgets developed for home air purifiers, the mask has miniature electronic fans to regulate the air flow. It also has filters to prevent the user breathing in infected droplets, making it potentially effective for those needing Covid-19 protection while working in crowded environments.

The fans have sensors to detect how vigourously the user is inhaling or exhaling, and can regulate their speed so that breathing is “effortless”, according to the manufacturers, South Korean tech giant LG Electronics. It also allows users to wear spectacles without exhaled air steaming their glasses up. The mask, described by LG as a “personal

air solution”, is due to go on sale later this year. No price has been set for it yet, although experts believe that in order to be commercially viable, it will have to cost no more than a couple of hundred pounds at most.

“At a time when consumers are seeking ways to make life safer and more convenient, it’s important that we’re able to offer solutions that add measurable value,” said Dan Song, president of LG Electronics Home Appliance and Air Solution Company.

LG teamed up with Korea University to design the shape of the mask to ensure that it fits the face tightly. It weighs roughly the same as a pair of ski goggles, and has lightweight batteries that offer up to eight hours of operation.

The mask is in part a miniature version of existing electronic breathing masks used by doctors and scientists working in hazardous environments.

Dr Julian Tang, honorary associate professor in respiratory sciences at Leicester University, added: “Most of the time we don’t need that kind of protection, but if you were a tour bus guide, for example, working in crowded conditions with lots of unmasked people, you potentially consider this kind of device.”
