Tackling the minions of air pollution

Sir James Dyson is a British inventor extraordinaire whose company since 1993 has earned 7,500 patents in a broad swath of applications from vacuum cleaners to hair dryers. His flagship innovation is a bladeless fan and his latest is an air purifier, using this fan technology.

Last month, Dyson previewed the Dyson Pure Cool Link purifier  in Delhi and plans to launch the product in India in early 2018.   This is a first-ever  WiFi connected purifier and claims to capture particles as small as 0.1 micron. Like the Dyson bladeless fan, this is  a very  thin and sleek device. The trick is proprietary Air Multiplier technology that draws in small amount of air to produce high-velocity airflow. This is further multiplied by passing  the air through an airfoil shaped ring, creating a local low pressure zone. Desktop and Tower versions sell abroad for $270 and $400.
