The Wall Street Journal has a good article, "Key to Preventing Covid-19 Indoors: Ventilation," on better practices for indoor ventilation in the face of the coronavirus and the need for frequent air exchange to remove virus aerosols.

This is exactly what i meant in march about the inability of the US to learn from other countries.
ReplyDeleteAir filters sales have exploded in Asia post SARS (2002). That boom was mostly in Japan/Singapore/Taiwan (richer asia).
The chinese came along a bit later 2008 or so and nave massively changed the market.
First thing I did in March when lockdown was coming was order a sharp air filter. I paid 250, price now on Amazon is 500.
Of course the HEPA thing only helps so much, what you want is a type of plasma or ionization. Of course that was invented back in the 1900s.
Also did an emergency capital repair to building exhaust vents to help move air inside the building.

from a building/city point of view what you need is mandate more opening windows, better interior ventilation, and air exchange.
I'd glad six months later it is finally in the media.
also this (VG)

1. WRT militantly not learning, while I have a lot of problems with this piece, Zakaria makes the point that American exceptionalism is the reason we don't seek out best practice.

Maybe it is.
I did intend to write about it.
2. Thanks for the BBC piece. Interestingly, I remember being really "shocked" when I was in Germany that the hotel windows opened. Because I didn't expect this to be the case, it took me awhile to figure out that it was a possibility.
... but you would think with things like Legionnaires disease, that we'd have figured out that homogeneous internally-focused air ventilation systems might not always be the right way to go.
