CARCINOGEN

Those blackish brown macroparticles were filtered by this window screen.You can see those dust after the net was washed with  soap & water had this net not there my family members would have inhaled it. Why am posting this in my blog? Just to remind people the gas and fumes you inhale at home and out side are more dangerous than cigrette smoking.Those  black brown particles are carcinigenic.So viewers don't think that you will not suffer from cancer lung because you do not smoke.
