Your girlfriend is an extremely patient and accommodating person. 😊

I was in NYC this weekend and thought of your work because there were places where the air felt polluted and really smelled. I wonder if you could put a box like this over a subway vent and other sources to capture pollutant particles. What do you think? Any idea if this has been done before?

I actually don't know how much air conditioning there is on big metropolitan transport systems. Maybe I should take my meter down into the Tube

That would be really interesting.

The _open window_ scenario depends on fresh air outside. When outside air *brings* the contaminants... wildfire smoke, neighbors vaping, traffic emissions.

I‘m curious if you get the same CADR results when burning matches instead of frying kale.

Also FYI, a few years ago I talked to people who have been in this field for a long time and they claimed it was fairly easy to achieve „well mixed“ conditions. Apparently you just need a simple fan that rotates direction where it faces and I guess you put it in one corner of the room. Of course, take this with a grain of salt since it’s only second hand wisdom and I don’t have a paper to point to.

Thanks for the comment Max, I’m gonna indeed try doing the matches, it seems a lot easier. Also thanks for the tip on well mixed ness, gonna buy another fan :)
