As I used a lot of masks with Corona 19, a wide variety of masks appeared, including masks that you can drink while wearing.

In the United States, masks that automatically sterilize and ventilate appear.

<Oh! Click> The third search term is'Self-ventilation transparent mask'.

A mask developed by an American medical device company.

The sensor is attached to the bottom of the chin in a transparent silicone material.

This sensor measures the external air quality and the user's metabolism and provides ventilation automatically.

It is said to be the world's first active mask.

Self-sterilizing filters with UV light also remove germs and odors in real time.

It is said that it has already been approved by the US FDA.

In the United States, many people expect this self-ventilating mask.

About 13,000 people participated in the funding, which raised a donation of 2.5 billion won.

Estimated prices range from late 50,000 won to 230,000 won per model.

The company expects that it will be useful for smart phone face recognition and communication for the hearing impaired, even by being transparent to ventilation and sterilization.

The netizens said, "Oh, the transformation of the mask is innocent!" "If you breathe, will you sweat less? Will reduce the discomfort index in the summer^^"
