Hello, I were looking for smartest forum on internet and found this forum. I guess, will get any help from here, because this quality of life isn't even worth living. Living in third world country - Lithuania and here air is very polluted. Mostly it's from solid fuel firing winter time. Of course there are plenty of factories, which doesn't have proper air-filtering systems to release safe air to atmosphere. I read a lot of articles in which i found, that carbon monoxide does heavy damage to brain and while air is most polluted (mostly evening) it's hard to breath for me, feeling very weak, having headaches, getting 0.5-2s black screen in eyes. Were looking for solutions for months, best I could find is this video(youtube url), but I can't find where I could buy box fan in my country. Do You have any suggestions for me?
