China’s anti-pollution tech is booming, but it can’t make dirty air go away

Behind a red wooden door, down a Beijing alley, lies what is allegedly the cleanest air spot in the smog-sodden city. Numerous air purifiers gently whir in the Breathing Space Courtyard, in the Chinese capital’s Beixinqiao area. Dotted around the courtyard’s main building, which houses the headquarters of Beijing startup Origins Technology, are small, sleek alarm clock-like monitors showing air quality index (AQI) readings. Called Laser Eggs, these 499 yuan (£53) monitors display flicking numbers that seldom go above 10, [...]

Clearing the air:How effective are the purifiers?

Air purifiers are devices that aim to clean indoor air by filtering out particulate matter like dust and pollen, gaseous pollutants like hydrocarbons, and unpleasant odours.

Manufacturers usually promise additional benefits through the use of other [...]

But autumn brings its own batch of allergy triggers: ragweed pollinates in the fall and can travel hundreds of miles, and corn mazes, piles of leaves and jack-o’-lanterns can harbor mold.
