AMSTERDAM — A Dutch tech company has unveiled a giant vacuum cleaner that purifies the air by sucking toxic particles out of the atmosphere. <br /> <br />The machine can filter 100 percent of fine particles and 95 percent of ultra-fine particles in the air, inventors the Envinity Group wrote on the company’s website. It can clean about 800,000 cubic meters of air an hour. <br /> <br />Fine particles in the air are caused by emissions from burning fuels and industrial combustion. Fine particles are particles smaller than 10 micrometers and ultra-fine particles are smaller than 0.1 micrometers. <br /> <br />Governments, businesses, and airports have already expressed an interest in the machine, according to RT.
