Your purifier cleans the air. greenwaterHOME renews it.
Filtration was just the beginning.
First, the familiar part.
HEPA and carbon filters catch dust, smoke, pollen and VOCs before anything else happens.
The invisible problem, addressed.
Living micro-algae absorb the CO₂ that builds up in sealed, air-conditioned rooms — the part no purifier touches.
Let's Bring Oxygen Back
Through photosynthesis, the algae release oxygen back into your room. The same process as a forest, built into your space.

Air purifiers filter what is floating in the air — dust, smoke, and VOCs. They cannot reduce CO₂ or produce oxygen. greenwaterHOME does all three: filtration, decarbonization, and oxygenation.
-
In a fully sealed 8×8×8 ft room, greenwaterHOME reduced CO₂ by an average of 32% per hour. The test used two independent CO₂ monitors with readings taken every 15 minutes, repeated every day for 30 days.
-
greenwaterHOME is designed for standard bedroom and living room sizes of approximately 500 sq ft— sealed, air-conditioned spaces where CO₂ tends to build up. Results vary by room size, occupancy, and ventilation.
-
Yes. Micro-algae is a natural, non-toxic substance — it poses no risk even if touched or accidentally consumed. greenwaterHOME operates without releasing any chemicals or harmful byproducts.
-
Every 6 weeks. Our team will reach out when it is time — you do not need to track it yourself.
-
Typically once a year. Our technicians check the filters during service visits and will let you know if they need replacing sooner.
-
No — greenwaterHOME is designed to be always on. Auto mode follows a natural morning-to-night light cycle that is ideal for the micro-algae, so you never need to adjust it.
-
RO water only. Tap water can affect the micro-algae culture. Each bay requires 4 litres at setup.
-
Yes, but with care. Eject the three bays first, move the device, then reinsert the bays. Moving it with the bays inside can disturb the algae culture.
-
You can pour it directly into any plant soil around you. The nutrients in the micro-algae culture are excellent for soil health.
