Treepex is not a concept, but rather a real device that claims to use living tree cells compressed in replaceable cartridges to transform carbon dioxide into oxygen, emulating a tree's ability to filter polluted air into mineral-enriched air. It was developed by a Georgian, Tbilisi-based, startup using a new technology called CRISPR, which is allegedly able "to extract the DNA of actual trees to recreate the living cells that are responsible for photosynthesis" by simply inserting a cartridge into the tubular Treepex.

"When you take a look at a leaf with a microscope you can see the cells which are responsible for the photosynthesis. And that's only a very, very little part of the entire leaf. Simply, think about this as if thousands of leaves were squeeze into the small cartridge. Basically, you will have a supply of fresh air always on hand. The device is easy to use, portable, and handy. Just imagine taking your bike to work, but instead of inhaling all the exhaust of cars, you can breath fresh air! Or, what if you live in one of the most polluted cities? Just use Treepex when you walk down the street without any worry you may kill yourself by simply breathing," said the company.
