Great product, easy to travel with
Great water filter, water tastes great and keeps me healthy. The jug is light and easy to travel with.
Subscription worthy
It’s great. We have a subscription so we can replace it every 3’months. It’s easy to set up the subscription so we don’t have to think about reordering it, it’s easy to replace and it works.
Delicious and healthy water
Our Earths Water jug has been the best addition to our household. I love knowing that nasties from city water are being filtered with these cartridges that are super easy to replace every 3 months and every time we have people over they comment on how delicious the water tastes from the jug. My husband and I are also loving knowing we are supporting our health during preconception.

Refreshing water!
It is my second order of earth’s water and I have decided to subscribe to the automatic delivery of filters because the filter makes such a huge difference in how the water from Sydney tastes and feels. After a long trip abroad, all I wanted was to taste the filtered water at my home. So happy I found this company!
