I live in a semi-urban area, where most surrounding houses use charcoal or black coal to heat them. Since my flat is on the top floor (2nd), the outside chimneys are not that much above my roof and, in consequence, during the few months of winter, depending on the wind I'll get an unpleasant smell of burned coal in my apartment.
So, how to get rid of it?
The obvious answer is to close all gravitational ventilation inside the flat, which is what I do at the moment and which is cumbersome and not a permanent solution as the gravitational ventilation needs to be turned on at least periodically.
I was thinking about buying lots of plants. In the vain of this TED presentation and blog post: http://mattnt.com/2010/08/15/air-filtration/
The question is - what kind of plant/plants would deal with this problem most efficiently?
Or maybe there is a better solution?
