In this period of pandemic and daily protection against the Covid-19 virus, LG is unveiling a mask with an air purifier. Equipped with sensors and fans, it filters inhaled and exhaled air. It also incorporates UV-LED lamps to destroy germs and certain viruses.
Despite the health crisis, the IFA trade fair will be held September 3-5 in Berlin, and LG could not imagine a better occasion to present the LG PuriCare Wearable Air Purifier . It is an electronic mask, ideal in this period of pandemic , and it could daily replace the fabric or surgical masks used in the streets or in enclosed or poorly ventilated places.
According to LG, this purifier of air cell includes two filters HEPA H13 , similar to the filters used in air purifiers found for the house. Another essential element in this period of pandemic is the presence of UV-LED lamps to eliminate bacteria and other viruses . However, LG has not yet obtained anti-Covid-19 certification and so it should not be imagined that droplets of the coronavirus will be totally blocked by the filters.
A sensor adjusts the fan speed
Clearly, the effectiveness against the virus is not 100% sure, even if, like any very good mask, it acts as a barrier and protects its user and those around him. In fact, the manufacturer donated 2,000 copies to a Seoul hospital to protect healthcare workers.
Inside this futuristic mask there are two ventilators and the respiratory sensor. The air is thus absorbed, filtered and then exhaled. All in complete safety, but also in comfort since the mask adapts to the user’s breathing. For this, the sensors detect the cycle and the volume of the wearer’s breathing and allow the fans to be adjusted with three different speeds. In short, the ventilators speed up automatically to facilitate the entry of air and they slow down to reduce resistance during exhalation to facilitate breathing.
An application to detect the efficiency of filters
As the assembly includes electronics, it incorporates an 820 mAh battery, and LG announces eight hours of autonomy for undemanding use (outside temperature of 25 °), but only two hours in more complicated conditions. We think of an enclosed and crowded place, like public transport.
Another data to highlight is the LG ThinQ mobile application , available on Android or iOS . Via a notification system, it indicates when the filters need to be replaced for optimal performance and better protection. Two unknowns: price and availability. LG timidly suggests an arrival at the 4 th quarter in some markets. Perhaps it should be expected to be released only in Asia, especially due to the various tests and certifications required by health organizations in Europe and the United States.
