Is there any way to use phytoplankton to clean air in cities?

Question

I think recently I saw something about a man entombed in an underwater container that had some sort of biological filter, I assume it used phytoplankton but I'm not sure.

So I'm curious, are there any phytoplankton based filters for the home, or the city applications to reduce smog?

Answer 1

Plants and phytoplankton are primarily responsible for cleaning the air all over the world. If it were not for plants we would have long since choked to death on our pollution, even if we could come up with an alternative source of oxygen. So in principal you have a good idea. To the best of my knowledge there are no commercial products designed in the way you describe. However you can take advantage of the air cleaning capabilities of plants just by keeping house plants in your home. They can be any kind of plant and do not specifically need to be phytoplankton.
