This time, KAIST researchers have developed a mask that retains its performance even if it is used more than 20 times.

When can we meet on the market?

<Oh! Click> The first search term is 'Mask for one month per sheet'.

Research team of Professor Kim Il-doo, Department of Advanced Materials Engineering, KAIST has developed a nanofiber filter that maintains filter efficiency even after washing.

Previous filters disappear when static electricity formed on the fiber surface comes into contact with moisture, so the filter efficiency drops sharply after a certain period of time has passed or after washing.

However, the research team's filter using the 'Insulated Block Electrospinning Method' was said to have been washed more than 20 times with soap and immersed in ethanol for more than 3 hours.
If you wash and reuse 10 to 20 times with ethanol spray or soap per filter, you can use 2 or 3 filters for more than a month.

The research team said, "We will go into production immediately after going through relevant procedures such as approval by the Ministry of Food and Drug Safety."

The netizens said, "It's good news for a long time. Thank you guys!" It responded to "The best development at the moment! I hope it will go on sale soon!"
