Clean air & water solutions The main indoor air solution Tree offers is an externally-built terrarium involving plates using algae & microfluidics to regenerate oxygen while visually creating a mini artificial rainforest within, working via solar panels installed above the terrarium. The main water solution is a filter mounted on the main water pipeline, filtering all toxic elements from the water through reverse osmosis and granular activated charcoal technology. These two solutions make up the basic in-house system implemented by Tree, with additional elements of furniture, decoration, plants and seeds to create a natural habitat within indoor living spaces - including moss murals & tropical bathroom environments for modern residences.
