Nano-filter Extends Life of Face Masks

Mar-20-20 Researchers in South Korea have developed a nano-filter that extends the life of face masks that are now in such short supply.

They claim the filter can maintain its filtering function even after being washed 20 times making the mask reusable for about a month.

An insulation block electrospinning process was used to manufacture orthogonal nanofibres by controlling the alignment of the nanofibres. This structure maximizes filtration efficiency which is different from existing disposable masks.
