Brazil has been dealing with massive criminal wildfires for the last few weeks, and the air quality is record-breakingly bad. Besides other obvious issues (ineffective government response in going after the criminals setting fires, climate change making everything worse), hardly anyone is talking about how to deal with the immediate air quality problem. It's a bit bizarre.

People aren't widely adopting PFF2 masks and air purifiers. These remain somewhat niche topics even though pretty much everyone is suffering. To be fair, there are occasional media reports and government alerts about how to deal with the situation, but these feel too little, and one only gets them if actively looking for them.

  1. It's affecting tens of millions of people (scale ✓)
  2. Barely anyone is really addressing it (neglectedness ✓)
  3. We have simple solutions that could help a lot (tractability ✓)

It feels like there's potential for some serious impact if one approaches this right. It may be a severe case of availability bias, but all this is making me value air quality more as an EA cause area.

Thank you for writing this - I'm working on a post going over how much cheaper someone could make air purifiers for and it surprises me that it's not a more common topic of discussion. Some food for thought while I finish it up:

  1. Indoor air quality affects so many people to at least some extent - consider air pollution, viruses, allergies etc. 
  2. Making air purifiers even slightly cheaper vastly increases the number of people globally who can afford one, and directly increases the cost effectiveness of any intervention which involves paying for them. 
  3. Noise is a common reason for people under-utilising air purifiers and the affordable end of consumer hardware hasn't solved for this yet. We know this because best-in-class clean air delivery rate (CADR) at a given noise level can be achieved with what is essentially a box with 2-4 air filters and some computer fans on the side (computer fans have become remarkably capable at low noise levels in recent times). These kits can be bought but minimal competition in the space means no one is anywhere close to the reasonable price floor.
  4. Competition in the air purifier market has partially been on features which are not necessary when the goal is optimizing CADR/$. Ionization, timers, remote control, app connectivity, odour removal etc. can be done away with for the purpose of achieving "one billion air filters in this decade" or anything of similar scale.

It almost seems too simple: the many things floating around in the air cause a huge amount of death, illness and general discomfort. If you push enough air through a fine enough filter you remove the stuff in the air. If you make the filters cheap and quiet enough, people will be able to buy them and we can send people more of them for the same price.

Of course the air quality problem with respect to pollution is obviously something much more difficult to solve than simply chucking air filters everywhere since people also have to be outside for much of their day. 80,000 hours podcast 170 "Santosh Harish on how air pollution is responsible for ~12% of global deaths - and how to get that number down" is a great introduction. But regardless, people ought to be able to have some refuge somewhere, and indoor filtration and wearing a mask are the only ways is the only way someone can individually guarantee that for themselves. 

There's a really cool start up I believe in India having integrated HEPA filtration in bike helmets. So many people there ride 2 wheelers and are stuck in abysmal air quality at least one or two hours every day.

Securitization is indeed coming 

"OpenAI appoints Retired U.S. Army General Paul M. Nakasone to Board of Directors"

What do you mean by "securitization"?

Securitization in the international relations sense, that is, framing frontier AI development as a major (international/national) security threat that requires top cybersecurity, people with experience in the department of defense, etc.

ah, I was only familiar with the finance sense and my initial googling didn't turn up the IR sense at all, my bad
