From the paper:
> Cutting annual mean concentration of particulate matter smaller than 10 μm (PM10) in China to the Environmental Protection Agency’s standard (50 μg/m3) would move people from the median to the 63rd percentile (verbal test scores) and the 58th percentile (math test scores), respectively.
It seems like HEPA air purifiers should help quite a bit if one spends on a lot of time indoor. At least having one in the bedroom would reduce exposure time by at least one-third, which should be useful.
It also sounds like by investing modestly in air purifiers, most offices in polluted cities could even net productivity gains from healthier employees who suffer less from allergy and congested airways, in addition to long-term maintenance of their cognitive function.
- rcMgD2BwE72F 8y agoWhy spend money in air purifiers when you can invest in things that reduce the emissions of pollutants at the source? Doesn't the production and usage of air purifiers contribute to air pollution over its entire product life cycle?

- nopinsight 8y agoThat is an ideal situation most of us do not have much influence on. We can help lobby/advocate at the margin but check out who we are up against esp in developing countries, where the problems are most acute. In the meantime, air purifiers reduce the extent that our health deteriorates. The effect of air purifiers production is relatively tiny compared to pollutants from the rest of the economy.
