Testing of reusable Copper Mask

Editor’s Note: Scientist, inventor and KOL Dr. K Kwong has been closely monitoring and critically commenting on the Hong Kong government's measures against COVID-19 with his expertise in science and unique humour. He also invented a reusable cloth mask for use with disposable filters and made the design available for the public to make at home and mass produce.

(10 May) 051023 【01Mask】The fourth washing today. The inner layer took 30 minutes to absorb enough soapy water to wet through the filter. It took another 45 minutes to rinse the soap, otherwise it would get mouldy. I am 100% sure no mask maker would send a sample after 60 washings to Taiwan for the test!

Why isn't our government following his footsteps?
