How it feels to live with greenwaterHOME

★★★★☆  4.3 out of 5 — 221 reviews

I have now been using this product for more than a month and I can see a tremendous improvement in the air in my clinic. People feel more fresh after coming here.

Dr (Prof) Suresh Gupta
Pediatrician · Allergy & Asthma Specialist

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.

Dr Taniya Bakshi
Healthcare Professional · New Delhi

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

Dr Poonam Gulia
Art of Living Meditation Coach · Gurgaon

Not only does the air feel noticeably better, the product also looks beautiful in my living room. It's definitely a conversation starter.

The stuffiness in my room is completely gone, and I feel mentally lighter around the Air Synthesizer.

How it works

Filtration was just the beginning.

01
Filtration
First, the familiar part.
HEPA and carbon filters catch dust, smoke, pollen and VOCs before anything else happens. Three stages of filtration — before the air even reaches the algae.
02
Decarbonization
The invisible problem, addressed.
Living micro-algae absorb the CO₂ that builds up in sealed, air-conditioned rooms — the part no purifier touches. The same process a forest uses, scaled to fit your space.
03
Oxygenation
Bringing oxygen back.
Through photosynthesis, the algae release fresh oxygen back into your room continuously — so the air that greets you in the morning has been quietly working all night.

Why greenwaterHOME

A different kind of air system.

No more afternoon crash
No more afternoon crash.
CO₂ builds up silently in sealed rooms. greenwaterHOME absorbs it continuously, so your afternoon feels like your morning.
Looks as good as it feels

Micro-algae photosynthesis — the same process that makes outdoor air feel fresh — now built into your room.

Diving into greenwater

Everything you need to know.

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 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.
Pour it directly into any plant soil around you. The nutrients in the micro-algae culture are excellent for soil health.

"It's getting . . . greener?"

That's great. The darker the algae gets, the more it's been growing. Just like any plant — that means more CO2 absorbed, more fresh oxygen in your room.
