Nanofiber respirators from the VK line work on the double-barrier principle. First barrier is a nanofiber membrane which immediately and reliable captures up to 99.9% of viruses and bacteria. thanks to its extremely dense net of nanofibers. Then, the layers of accelerated copper take care of the deactivation of viruses.
Thanks to this, the respirators can be considered self-sterilizing, and they can be worn repeatedly without any additional maintenance for up to one week (for up to 168 hrs cumulatively), or until the respirator starts showing signs of mechanical wear and tear. The respirators are an eco-friendly and economical choice.
