Hand on heart, I’d recommend it to every family that cares about their home and wellbeing.

As a doctor, I’m always looking for ways to make our home healthier and more comfortable for our family. I’ve had the greenwaterHOME for almost a year, and I love how fresh our home feels even with the windows closed. Its algae technology releases oxygen into the home, and personally, I’ve felt fresher and experienced less brain fog since using it. The gentle sound is a welcome change from harsh white noise, and the customer service has been excellent.

In my opinion, it’s one of the most exciting innovations of 2026. Hand on heart, I’d recommend it to every family that cares about their home and wellbeing.

What people are saying

How it feels to live with greenwaterHOME

★★★★☆  4.3 out of 5

I used to keep my windows open regardless of the AQI outside because I cannot tolerate the CO₂ buildup. Since I have started using the greenwaterHOME, I have stopped opening my windows.

Dr Poonam
Art of Living Meditation Coach

Yes, the air in our office is much better even when we close the windows due to the air conditioning.

Sunaina
Brahma Kumaris

I got this because I have kids and multiple pets at home. I had a lot of concerns starting out … but after using it for a couple of months I am quite satisfied.

Sangeetha

Breathing is a lot easier and I can feel that the air is fresher … My recovery time after a demanding workout has been cut short by half.

Ashok

I had my semester exams coming up … This time, however, they went like a breeze. I was able to focus better while studying at home too.

Nidhi

My wife has been suffering from severe cough and other throat issues for a long time. Her coughing has reduced significantly since we have started using this Air Synthesizer.

Ashish

I have increased one cycle of Suryakriya since I started using the greenwaterHOME. I feel less strain in my throat when I practice my vocal exercises as well.

Vaishali

I frequent Uttarkashi because I love the air there. On good days, I feel like the atmosphere in my home is almost as good.

Monishita

Being a yoga practitioner, I found this very helpful, even though I am in the habit of keeping my doors and windows open at home.

Akshata

I got this as a gift from my son. I quite like it, and my parents have found it useful as well.

“The air feels so much lighter, and that was the first thing I noticed. After a heavy session, I walk into a room that feels genuinely fresh instead of stuffy. My recovery after workouts feels noticeably better since I started using it. If you take your training seriously, the room you recover in deserves the same attention as your plan.”

"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.
