there we go. and it's in the lab where we'll get to see moss�*s super power. the plant acts a lot like a human lung, whose high surface area can absorb a lot of the air in one go. and just like the lungs of a smoker, which end up getting blackened by tar, moss could act like the lungs of a city, eventually being covered in the stuff that we don't want to breathe. so, this is from our one active products. and the black — the black bits are the... exactly. this is the fine dust or particles from polluted air. and these are the green cells. and it means that the moss is still healthy because it's green. but they are pretty powerful. really good. moss fan. well, yeah — i am, somehow! as well as pulling pollutants out of the air, there's another advantage to these biofilters, too.
