This «smart» mask is easier to breathe through


But LG promises no protection against Corona.

LG’s battery – powered face mask will make it easier to breathe than through traditional cloth bandages and the like.

The South Korean electronics manufacturer LG has announced that they are ready with a battery-powered face mask. This should be easier to breathe through than traditional cloth bandages or face masks, which become very clammy after a short time. This is one of the things that LG’s battery-powered mask will prevent.

With or without face mask: feel free to breathe well before pronouncing its name, which is «LG PuriCare Wearable Air Purifier».

Does not specifically mention Corona protection
The PuriCare mask is described as an air purifier.

LG does not specifically mention whether the mask can stop the Corona virus or not, but generally points out that it has a HEPA filter for filtering unwanted particles. This HEPA filter will remove 99.97 percent of all particles from the air.

According to the New York Times, a Corona virus is only about 0.125 microns in diameter. At the same time, they write that even though a HEPA filter is not certified to filter out particles smaller than 0.3 microns, they are according to a research report from NASA well suited to filter out particles down to 0.01 microns, ie far below the size to the coronavirus.

The mask has a fan that is constantly synchronized with your own breathing. When you breathe in, it goes faster, and when you exhale more slowly. The ability to regulate speed in three levels based on inhaling or exhaling, as well as adapting to the different amounts of air you need when walking or just sitting still, will help make breathing as effortless for you as possible.

The mask should also be able to disinfect itself using UV light.

The 820 mAh battery should be able to drive the mask, or rather the fan in it, for only between two and eight hours based on what activity the wearer is doing.

In addition, LG has not stated the weight of the mask, which looks both large and heavy to wear for a long time. Another question that is not answered is whether the fans are noisy or not.

Does not protect others from infection
It is important to note that masks with valves, as LG’s model has, are generally not considered to protect against the wearer spreading any virus to others. Masks of this type thus primarily protect the wearer. The press release from LG then also explicitly states that the mask «takes in fresh air», but says nothing about the air that is returned.

Thus, the mask seems to be a bad choice, as masks used outside among people where they are recommended in Norway should both protect you from others and others from you.
