The two masks are all made of PET environmentally friendly plastic, which are manufactured by vacuum blistering and are lighter in design than the previous one. The forehead can be ventilated for easy ventilation, and the rubber band is replaced by tape to make it more comfortable for long-term wear; the coverage area of the "reinforced" mask covers the head. Wen Xiaozhong, Dean of the PolyU School of Engineering, emphasized that the two masks are not for medical use and do not need to be approved by the Hospital Authority. They can be cleaned and disinfected with alcohol or tincture after each use, and can be reused 50 to 60 times, but cannot be washed with hot water.
PolyU executive vice president Wei Bingjiang said that the epidemic is expected to last until summer and frontline workers need to work outdoors. Therefore, the mask design this time pays attention to ventilation. For example, the position of the forehead can be ventilated and the spacing can increase stability during wearing.

PolyU's team made prototypes with 3D printing technology and took the lead in trials at social welfare organizations, including staff of elderly homes, caregivers for elders, and cleaners. Zeng Wanji, the service director of the Hong Kong Christian Service, said that when the elderly care for the elderly, it is inevitable that they will have close contact with the elderly, such as supporting movements and assisting in bathing. The cleaners also need to clean the toilets, which will inevitably be splashed with sewage. Make them often worry about when they go to work. It has been said that wearing a mask can effectively prevent water droplets, etc., and make them feel more at ease when working.
Wen Xiaozhong said that the protective mask has been patented and delivered to local manufacturers for manufacturing in the mainland. It is expected to produce 30,000 by the end of this month for use by school students and donate to frontline social welfare agencies. The article pointed out that this time the mask could not be manufactured in Hong Kong, because there is no factory in Hong Kong equipped with vacuum blistering equipment. It took the team one month to find a Hong Kong company with a relevant factory in the Mainland. Exportable. The team is also discussing with the industry, hoping that it can be sold in the market, with the price of 40 to 50 yuan each. The mask is also available in children's size, but has not yet been put into production, and is planned to be launched soon.
