a team of Dutch inventors has unveiled a giant air-cleaning vacuum that they say filters out fine particle pollution from the surrounding air, but this project isn't about art, it's purely about functionality.
"It's a large industrial filter about eight meters long, made of steel... placed basically on top of buildings and it works like a big vacuum cleaner," Henk Boersen of the Envinity Group, the makers of the device, told the AFP.
The device can suck in air from a 300-meter radius and from up to four miles above and can clean 800,000 cubic meters of air an hour. It filters out 100 percent of fine particles and 95 percent of ultra-fine particles, based on prototype tests carried out by the Energy Research Centre of the Netherlands.
All they need now is to build another two dozen coal-fired power plants to run the vacuums.

I am only pointing out that we don't breathe "pure air". For whatever reason, if you find yourself in a location near one of the poles, you will be breathing clean, pure air, laden with very few if any impurities. That means organic and inorganic impurities. There isn't much that grows there, and there aren't a lot of people there either.
That "pure air" is refreshing, in a way, but there is a cost to go with it. The environment, taken as a whole, is not conducive to growing crops, or to long life, or the American Way of Life.
Down here at the lower latitudes and lower altitudes, you aren't going to breathe "pure air". The air, wherever you are, if full of particles, both organic and inorganic. Any place that the environment is conducive to life, life fills the air with all kinds of stuff.
