疫情持續下口罩難求,香港大學化學系博士K Kwong鄺士山日前研發出可循環再用、香港製造的口罩「HK MASK」,更把圖紙上載到網上教全民DIY。

** K Kwong表示,可利用2張紙巾或1張廚房紙充當濾芯,可以做到70%過濾(= N70)。

** K Kwong提醒,濾芯只作一次使用,建議每4小時更換;若果DIY製作,建議用棉類物料,因為需要承受100度以上高溫消毒。

K Kwong, a doctor at the HKU Department of Chemistry, has developed “HK Mask", a mask with a changeable and reusable filter.

The HK Mask is composesd of a cotton mask cover and a specialized filter. The cover can be reused after decontaminating it with hot water or with ironing, while the filter, utilizing nano technology, has to be changed at a recommended rate of once every four hours. K Kwong added that standard tissue paper can also be used in lieu of the specialized filter if the filters are not available, and explained that using two tissue as filter along with the cotton cover can already achieve 70% of the effect of N95 masks, filtering 70% of 0.3 micrometer particles in the air.

K Kwong did not intend to get the mask patented, and will disclose the design of the mask in the future to encourage self-initiated mask production to battle the disease. He hopee for the wide adoption of HK Mask even after the plague, and will also attempt to promote HK Mask in Japan to inspire a new hot trend.

⚠️ Outer cloth: use anti-bacterial fabric, please disinfect the mask after each use!
