口罩自救
Why face masks?
The main function of face mask are 3 folds:
1. If one got infected by the corona virus, wearing a mask will prevent her/him from infecting others in public.
2. If one believes he/she is clean of corona virus (up to 60% carriers do not have any symptom of the disease), wearing a mask will prevent him/her from being affected by others in public.
3. The more people wear a mask, the easier the country stops the infection of the corona virus. Carrying a mask in the public also remind others to wear a mask.
No one knows when the corona virus spreading will stop. The most optimistic prediction is that the globe will keep consuming face masks at least 3 months more on a daily basis after no more new cases are confirmed.
Why HK Mask?

常問問題
HK口罩的防護能力如何？
鄺醫生表示，使用廚巾作過濾器的HK mash應該能達到N95口罩的70%防護水平。研究仍然反映 N95 和外科口罩仍然是最合適的保護自己的方式，但我們認為：
N95> 外科口罩> 可重複使用的口罩> 重複使用的外科口罩（因為不能洗）>（好多了）不要戴口罩
HK口罩的外片和內片應該用什麼材料？
100％純棉。
100%純棉最大的好處就是可以用肥皂水洗，也可以用熨斗消毒。
100% 棉還提供了良好的空氣流動條件，使空氣能夠通過口罩的表面（內片 + 過濾器 + 外片）。
***防水材料可以有效阻擋病毒進入口罩，同時也阻擋空氣進入痕跡。在這種情況下，呼吸的空氣將來自口罩和麵部之間的縫隙，而不是通過口罩表面。
什麼是新的？
我們很高興在全球範圍內收到過多的主動反饋。一些工廠為其員工和客戶生產香港口罩。有些人甚至向社會捐贈了數千個香港口罩。以下是他們的部分作品：
