The Treepex, officially launched on Oct 9, is worn on the face and is said to replicate a tree’s process in filtering air.

The Tbilisi, Georgia-based developers say the innovation contains "the DNA of millions of leaves compressed into the brain of the device, the so-called cartridge".

Treepex takes no more than 30 minutes to charge with wireless charging technology, which should provide 24 hours of clean air.
