Inspired by Nature. Engineered for you.

greenwaterHOME combines 3-step filtration with the photosynthetic power of micro-algae to bring real freshness back to sealed rooms.

Filtration
Step 01
Filtration
Dust, smoke, and VOCs caught and cleared through a 3-stage system before anything else happens.
Decarbonization
Step 02
Decarbonization
Filtered air passes through a living micro-algae culture that absorbs CO₂ quietly and continuously.
Oxygenation
Step 03
Oxygenation
Through photosynthesis, the algae release fresh oxygen back — the same process as a forest, scaled to fit your space.

My sneezing stopped, and I no longer feel sleepy toward the end of my workday. Even the subtle sound of water feels calming while I work.

I don't open my doors and windows anymore. The air inside already feels fresher than outside.
