This personal air purifier concept would allow people to filter and purify outdoor air.
As climate change continues to worsen and there are already cities that require populations to wear masks on certain days due to smog and pollution, it is increasingly clear that poor air quality is affecting people's quality of life. Rather than simply filter out contaminants like other masks do, this mask works as a personal air purifier that actually destroys harmful bacteria and viruses. The 'Papr Mask' concept designed by Myeonghoon Lee also "eliminates odors, chemical contaminants, dust and second hand smoke." The mask is designed to fit lightly on the user's neck to avoid strain and discomfort.
In a perfect world there would not be a need for such a mask, but since the reality of climate change caused by pollution, waste and land appropriation is only worsening, the Papr Mask could help alleviate some of its consequences.
