Re: The health benefits of better air
#2In addition to lost life, there is also a cost to quality of life. Air quality is one of the biggest contributors to the risk of senile dementia. But also the gas composition is known to affect cognition in the short run as well, with a measurable difference in cognitive tests when indoor CO2 is elevated.

Downvoted because I don't disagree. But...

#5> Nothing else is so important while also being so easy to address.
It's actually not that easy to address if you don't have extra cash laying around. Most people in the world will not do the things on this list.
Other things it leaves out, like frying food (edit: I'm a moron, it does mention it down the line), or buying furniture or clothes that off-gas VOCs, or living or working in a place with fiberglass-lined air ducts, or using a gas range or oven.

I'm not sure which claim you're looking for a citation for, but if it was the CO2 and cognition claim, then I have a few for you.
This study made quite a few ripples when it came out: https://ehp.niehs.nih.gov/doi/10.1289/ehp.1510037
> On average, cognitive scores were 61% higher on the Green building day and 101% higher on the two Green+ building days than on the Conventional building day (p There was also this one, about decision making: https://ehp.niehs.nih.gov/doi/10.1289/ehp.1104789
> Relative to 600 ppm, at 1,000 ppm CO2, moderate and statistically significant decrements occurred in six of nine scales of decision-making performance. At 2,500 ppm, large and statistically significant reductions occurred in seven scales of decision-making performance (raw score ratios, 0.06–0.56), but performance on the focused activity scale increased.
This one is a high-level overview of the literature on air pollution and health: https://ehp.niehs.nih.gov/doi/10.1289/EHP4869

#7I love this article. But the article misses the use of plants to improve air quality! HEPA air filters can't filter out nano-sized pollutants

#8How is it possible to separate DALYs lost from high BMI from DALYs lost from low vegetables and/or low physical activity? The author never fully explains the methodology behind the graph.

#9Thank you for this extensive resource on air quality. Yes, it needs to get more attention as it is one of the main drivers of mortality of environmental risks.
One thing one has to bear in mind is that often when you optmize your home for low PM (e.g. with air purifiers and fixing of air leackage) your CO2 will get very high causing headaches and reduce cognitive performance.
So it always makes sense for indoor air quality monitoring to measure PM and CO2 in parallel.
We have open source, open hardware build instructions for a very reliable Air quality sensor that can be used to measure PM2.5 and also CO2 [1]. It is very accurate for the fraction of the costs of commercial sensors. You can build it for less than USD 20 (or with CO2 for less than USD 50) and send the data to our cloud server or any other backend.
I am more than happy to send you some free PCBs (you just paypal me the cost of the postage) and you can build your own sensor and log the data. Contact me if you are interested.
