Did some maths;
In London, the PM 2.5 per ug/m3 was 17.3 in October ( it was a high month )
According to the study, with those numbers we're talking about a 30 cubic centimeter reduction.

BTW. In Cracow, Poland we have a second month of very high PM2.5 levels (lower ones are about 40 ug/m3, highest being above 200 ug/m3) see http://monitoring.krakow.pios.gov.pl/dane-pomiarowe/automaty... or http://aqicn.org/city/poland/malopolska/krakow/aleja-krasins... Too much coal based heating and too little wind.
