Chinese Student Invents Portable Air Purifier
Wuhan University student Chiu Chih made an interesting portable, individual planter. The goal is to keep the inhaled air clean, even when the air around you is polluted.
A planter (aka a mini-factory for the production of clean air) is a backpack connected to a mask covering the mouth and nose of a person.
Currently, the cost of the device is $132. This is not a finished product, but a design concept. The student was inspired by the problem of air pollution in China.
In general, there is an alternative to inhaled toxic air.
