I have been to Delhi many times in my previous jobs. On one occasion one of my colleagues got massive breathing problems and needed hospitalization and oxygen. On really bad days cleaning your nose turned the tissue black.
Air purifiers are not able to keep up with the pollution especially if your house is not air tight. What works well is to make use of positive pressure systems with high performance filters [1].

- akgerber 4y agoThese descriptions remind me of Pittsburgh back before the Clean Air Act in the US— one apparently had to pack a second white shirt with them to work as the first was soiled with smoke by the end of the day. Buildings were and are still stained black decades after air quality had improved. My environmental history professor while studying in Pittsburgh was being treated for lung cancer in spite of never having smoked, and he thought it likely due to how smoky the city used to be. Pittsburgh's downtown and many poorer neighborhoods were located in deep valleys full of heavy industrial installations. I hope India makes the same progress on air quality as it develops that many richer countries have. Seeing things like its maturing domestic electric scooter industry is a reason for hope.
