Im looking for a filter that can efficiently and cheaply filter out things like regular city pollution to cigarette smoke for a project I'm doing for my biomimetics class, so I was wondering if there are any animals or plants that have this sort of mechanism in them.
Tress perform osmosis. Also, read about Baleen filter which filter was patented by a University in Australia based on studies of whales. Refer to:
https://asknature.org/idea/baleen-filters-water-filters/#.XeN3LOhKiUk
The baleen is a “filter mechanism that enables [filter-feeding whales] to collect plankton, small fish, and other marine organisms from the water during feeding. The combination of a sweeping action of the tongue and the reversing of the water flows as the whales dive and re-surface during feeding, enable them to capture and strain food, then clean their baleen prior to the next dive. The Baleen filter technology is an adaptation of this natural technique used by whales to keep their baleen clean and free from long-term deposits.
Hello Sebastian; The common wisdom is that indoor plants filter small particulates out of indoor air. I haven't seen any systematic study of that idea. If you can measure small particulate concentration indoors with and without houseplants. I'd use LOTS of plants to start out. Best of luck with the project. Jim Des Lauriers
