Our relationship with water needs critical examination. As fresh water is becoming scarcer, we need to search for new connections to innovate. Enter Biosphere: a plant-based water filter.

Biosphere filters ‘dirty’* water and makes it suitable for human consumption. A small portion of the water is transformed by the plant into sugars for it to grow. And it ‘breathes out’ clean water as condensation for you to collect and drink.

In about a day, you have one glass of water, with the distinct flavour of the plant with a completely different flavour profile than an infusion. A slow tea, if you will. Because it takes the plant or herb about a day to filter one glass of water.


Because the system requires no electricity and low maintenance, it can bring several benefits to your home with minimal effort. For example, the plant filters the air in addition to water, it can produce food such as herbs or tomatoes and it provides a beautification of the home.


Appreciate water in a new way. Because we can’t afford to think of water as disposable. Our society is becoming sustainable, but I think that a change in our thinking is also necessary. With Biosphere, I want to ‘grow’ collaborations between humans and plants. A new lifestyle that transforms our home into a living ecosystem that we need to take care of.

And sometimes you need to slow down to appreciate the work plants do.

A laboratory for your house, a place where form follows function, for you and your plant. And even though your plant doesn’t need much attention, it is always a good idea to check it daily. Remove a leaf that fell down, or give it a little plant food. Or switch it up, and change out your tiny tomato for a young mintier plant.

An oak produces about 400 liters of water on a regular day.
