India, July 10 -- For as long as I can remember, buying a ceiling fan has been the most boring decision in setting up a home. You look at the blade size, maybe the star rating if you're feeling responsible, and you move on. Nobody debates fans the way they debate phones or TVs. Orient Electric is betting that this is about to change, and the Aero O2 is its opening argument.

On paper, this is India's first "oxygen-enriching" ceiling fan. That's a big claim to lead with, so I spent time with the fan running in a closed bedroom in Delhi, the kind of city where checking the AQI before opening a window has become second nature, to see how much of it holds up in daily life and how much is packaging.

The Aero O2 doesn't try to hide what it is....
