What people are saying
People notice the difference.
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 and I think this machine will help lots of children and parents.
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.
I don't open my doors and windows anymore. The air inside already feels fresher than outside.
Not only does the air feel noticeably better, the product also looks beautiful in my living room. It's definitely a conversation starter.

You’ve felt this.
You just blamed yourself.

Fresh air, indoors,

Inspired by Nature.
Engineered for you.
greenwaterHOME combines 3-step filtration with the photosynthetic power of micro-algae to bring real freshness back to sealed rooms.
Decarbonizing your every breath
0% less CO₂ per hour.
Fully sealed 8×8×8 ft room starting above 3000 ppm CO₂. Average reduction rate 32% per hour ±3%. Two CO₂ monitors, readings every 15 minutes, repeated daily for 30 days. Results vary by room size, sealing, occupancy, ventilation, and operating conditions.
"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.
