I started testing air purifiers early in 2016. My son suffers from respiratory problems, most likely caused by growing up in Gurgaon’s polluted air. As I sought out more information on pollution and air purification, I realised that very little scientific knowledge is easily available online. I also found that no one seems to be scientifically reviewing purifiers in India. I made two Facebook posts, here and here, to share my work. I also published a document online with all the data I’d been collecting.

Looking at the rising pollution after Diwali 2016, and the interest in my work, I have created this website so I can collaborate better with others.
