The vehicle has travelled to some crowded places like Miền Tây and Miền Đông bus stations, several industrial zones, the cultural house in Tân Bình District and other public places.
It was launched on February 6.
Phạm Quang Anh, director of Dony International Joint Stock Company, came up with the idea six months ago when COVID-19 was raging.
The masks it dispenses are certified as meeting Germany’s REACH standards for protecting human health and the environment.
They can be reused several times, reducing the impact on the environment, Anh said.
Beside donations from sponsors, Dony also plans to spend 5 per cent of its revenues on providing the masks.
The bus also plans to travel to Hải Dương Province, a COVID-19 hotspot.– VNS
