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.

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.

Indoor CO2 levels directly impact employee productivity, focus, and overall well-being. High CO2 concentrations lead to fatigue, brain fog, and reduced cognitive performance, making workplaces less efficient.

Beyond productivity, businesses must also now meet sustainability goals and reduce their carbon footprint. greenwaterHOME actively captures CO2 while generating fresh oxygen, offering a dual benefit for both employees and the planet.

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.

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.
