According to foreign media reports, in places with severe air pollution, many people will wear masks. Five Dutch undergraduates have recently developed a “plant rucksack†that can replace general masks to filter airborne particles and allow users to use it. Instantly inhale fresh air. It is reported that the rucksack has been designed and entered the manufacturing prototype stage. The inventor pointed out that in heavily polluted cities, it will be the main target market.
The rucksack, designed by student Delkron and others at Delft University of Technology in the Netherlands, is equipped with a filtering device that introduces outside air and filters through the roots of the plants in the rucksack to provide fresh air. The new invention won the design competition prize from the Dutch Greenhouse Horticultural Innovation Foundation (SIGN). They are testing which plant works best and for the time being consider aloe vera a good choice.
