Are Outdoor Purifiers (Smog Towers) a Solution for Clean Air? CEEW Experiment

In October 2020, the Delhi government sanctioned INR 20 crore to install a smog tower in Connaught Place. But, are outdoor purifiers a solution for clean air? Researchers at CEEW conducted an amateur experiment with a Smart Air Ladakh Mini Air Purifier to test its effectiveness in the open. The purifier has a clean air delivery rate (CADR) of 585 m3/h and is recommended for a room size of 85 m2. The CADR, initially defined by the Association of Home Appliance Manufacturers (AHAM) and well recognized by manufacturers, indicates the clean air volume delivered by the treatment system (usually in m3/h). The purifier was placed in ambient conditions facing east in a residential area at Okhla Phase II. Two low-cost sensors from Prana Air were used to record periodic measurements of particulate matter (PM) 2.5 at varying distances of 2 ft, 4 ft and up to 12ft from the purifier.
