Проект борьбы с незаконно рекламой
 
Established to combat mask shortages in Hong Kong, Procare HK Level 3 mask and level 2 mask strives to provide a steady supply of masks to all Hongkongers with four production lines that can produce four to six million masks every month. Procare HK has received the Q-Mark certification for excellence in manufacturing from the Hong Kong Quality Marks Council, with all masks meeting the international ASTM F2100-19 Level 1, level 2, level 3 certification.


To give back to society, Procare HK introduced the Procare HK Campus Mask Promotion Program to offer students from low-income families with discounts. In addition, Procare HK also provides free masks to nursing homes and low-income families to help reduce their financial burden.
