I’ve been using my earths water jug for just over a year now! I have to say I can’t drink any other water. Having it right there on the bench, encourages me to always rehydrate. It’s so easy to change the filter and appreciate the reminder email!

We purchased the 2.5ltr benchtop jug. It fills really quickly, fits in the fridge nicely, my little kids can handle this size and it's so easy to change the filter. Actually a bit of an odd taste to start but now the filter has been used for a few weeks, the water has a great taste.

We were buying boxed water for years, did the math, spending anywhere from 1,200 to 1,500 a year. This makes tap water actually taste drinkable and rivals the boxed water we were getting. Definitely worth the investment! Thanks Earths Water!
