greenwaterHOME: world's first indoor
created by
75 Plants
in your coffee table
The future of air purification isn't simply about filtering large particles. greenwaterHOME captures indoor carbon dioxide and generates oxygen using a biological decarbonization technology powered by micro-algae. You can improve your focus, sleep, and immunity without finding the space or time to keep dozens of plants.

With & Without
Air pollution doesn't stop when you close your windows, it starts. The World Health Organization says carbon dioxide levels above 1000 PPM are toxic. You’re probably reading this in a room with over 1500 PPM. This leads to headaches, decision fatigue, and cognitive decline.
Before
After
Don't just filter your air. Decarbonize your every breath.
greenwaterHOME generates as much fresh oxygen and captures as much carbon as 75 plants using microalgae.
We also use a 3-stage filtration system—Carbon, HEPA, and Pre-Filters—to remove PM2.5 and PM10 particles with 99.97% efficiency.
The perfect addition to your home, office, and fitness space.
Nature had the solution all along.
We just put it in a box.
Step One
Set up your greenwaterHOME Air Synthesizer in a room of your choice. Most useful in office spaces, fitness studios, and living rooms.
Step Two
Pour a culture of algae and its nutrients in each bay. The first Air Synthesis Kit is free when you purchase your greenwaterHOME.
Step Three
Turn on AUTO mode and forget about it for three months. That's when we deliver a new culture to your doorstep.

The Invisible Threat
More often than not, your headache, fatigue and brain fog have nothing to do with your caffeine intake; it's the carbon dioxide.
Since we spend 90% of our time indoors, we end up being exposed to high levels of carbon dioxide including in our gyms, offices, and bedrooms.
Chronic exposure to high levels of CO2 reduces the oxygen-carrying capacity of the blood. This weakens the immune system, making individuals more susceptible to infections, illness, and reduced recovery times from sickness.
The disrupted balance of oxygen and CO2 in the blood, which can impair your brain’s ability to function properly.
Long-term exposure to elevated indoor CO2 is associated with increased anxiety, stress, and overall mental health deterioration. In many urban office spaces, workers often experience fatigue, poor focus, and decreased overall productivity.
Air Purifier vs greenwaterHOME: Air Synthesizer
Most air purifiers rely on HEPA filters or ionization, which remove pollutants but don’t enhance air composition.
greenwaterHOME goes beyond filtration by using living microalgae to actively convert CO2 into oxygen. Unlike traditional air purifiers, it doesn’t just circulate the same stale air—it transforms your space into a fresher, healthier environment.
Old Algae, New Purpose
Your used algae isn’t waste—it’s a gift to the soil. Packed with nutrients, it enriches the earth, restores microbial life, and improves soil health naturally.
Whether added to your garden or a community compost, it helps regenerate depleted land and supports thriving plant life. With greenwaterHOME, every refill cycle contributes to a greener, healthier planet.
Engineered For All
We love pets, kids, and just about everyone! Safety is a top priority, and greenwaterHOME is designed to be completely non-toxic and family-friendly. Unlike chemical-based purifiers, it operates without releasing harmful byproducts, making it safe to use around children and pets.

Let's Bring Oxygen Back: Explained
Our founders’ family has over 5 decades living in New Delhi, India.
Starting 2016, among other things, the Delhi government has had to shut down schools for a few weeks because the air quality is beyond toxic.
Our mission is to help our future look more like the past than the present. We are bringing oxygen back.
