Smart Air is a social enterprise and B-Corp committed to changing the way we breathe clean air! We create incredibly effective air purifiers and share life-hacks and tips on protecting your health from poisonous air!In January 2013, PhD student Thomas Talhelm wondered why air purifiers cost so much. He bought a HEPA filter on Taobao, strapped it to a simple fan, bought a particle counter, ran some tests, and published the results on a blog he called Particle Counting.A few magazines wrote about Thomas's "re­discovery," and then the Beijing Energy Network suggested he lead DIY workshops to help other concerned Beijingers build their own.When people said they had trouble finding the right type of fan and a trustworthy HEPA, Thomas and his friends launched Smart Air as a social enterprise to ship fans and filters at an affordable price, to people all over the world.Since starting in 2013, Smart Air has been shipping simple, no-nonsense air purifiers and providing free education and knowledge on air pollution using our unique social enterprise model. The work we do and profits we make don't go into some rich investor's pockets, but helps more people across the world breathe clean air.
