Smart Air
Smart Air was founded by Thomas Talhelm in 2013 in Beijing, China. They are a B Corp, certified for their social, environmental performance, transparency and accountability. Their R&D, design and manufacturing is based in China.
Before launching their line of air purifiers, Smart Air focused on selling DIY kits (a box fan, a HEPA filter and a strap) and hosting workshops in Beijing to teach people how to build their own air purifiers.
Prices for Smart Air air purifiers range from $50 to $1,100.
