Grad Student Rigs Cheap Alternative To $1,000 Air Purifiers In Smoggy China

An anonymous reader writes "University of Virginia grad student Thomas Talhelm was living in Beijing on a Fulbright Scholarship during the winter of 2012-13, when air pollution was so bad scientists likened it to a nuclear winter. Those who could afford it were resorting to an expensive solution: air filters costing up to $1,000. Talhem built his own on the cheap, getting comparable particulate count results, and has started a company that both markets the product to middle class Chinese and shows others how to DIY."

He straps a filter on to a fan and this is noteworthy? Ok then.

He got similar results to a $1000 product, and told everybody how to do it.

That is newsworthy.

I suspect there are a lot of people in places with a lot of air pollution who would really like to have this.

Kudos to this guy.
