Nano-fiber mask ‘filter performance remains the same even when washed’
• . The electrostatic fiber filter used in the existing fine dust mask has a problem that static electricity formed on the surface of the fiber is lost over time.
• In addition, when moisture or water comes in contact, the static electricity function disappears, and the filter efficiency drops sharply and cannot be reused.
• In particular, even if it is soaked in ethanol for more than 3 hours, the nanofibers do not melt or warp, so it can be used for more than a month if ethanol is sterilized and washed.
• It was also confirmed that even if the filter was bent 4000 times, the performance of the KF80 mask (600 nm particles, 80% filtration efficiency) was maintained.

Important Notice: Discontinuation of Our Wiki Service

Dear Valued Users,

We hope this message finds you well. We are writing to inform you of an important upcoming change to our services. After careful consideration and analysis, we have made the difficult decision to discontinue our wiki site, effective one month from 2024/04/30.

This was not an easy decision to make, as we understand the importance of the resources and community that have been built around our wiki. However, due to evolving market conditions and strategic realignments, we must redirect our resources and efforts towards other ventures that will allow us to serve you better in the future.

What This Means for You:

  • Access to Content: You will continue to have full access to all content on the wiki until the discontinuation date. We encourage you to save or migrate any content you wish to retain.
  • Final Date of Service: The wiki will become inaccessible starting 1st June 2024, after which all content will be permanently removed.

We are immensely grateful for the support and contributions of our user community throughout the years. The wiki is being retired, but our team will be back soon with new services and apps.

Thank you for being a part of our journey.

Warm regards,

editoy Inc.
