preface:

More and more attention has been paid to the air problem. Living in Beijing, the most famous thing is smog. Just last month, all major news channels issued "the first red warning of heavy air pollution in the year". It has been haze for several consecutive days, and you can see the coming of haze from afar. On the first working day of the 2017 New Year, Beijing and other places welcomed the first fog red warning of the New Year. This heavy fog has something to do with the haze process in the new year.

Simple masks can no longer meet my daily purification needs. Erdun Purifying Treasure is a small, portable and deformable air purification equipment.
