Earths Water filters
Real kitchens, real customers. Here is what they say.
I absolutely love my water filter. I struggled to drink water for years as I hated the taste and could always smell the chlorine. The water out of my filter is absolutely beautiful! Iβm now drinking water constantly and Iβve told everyone who will listen that it literally has changed my life.
Sharon H. Β· 9L Glass Benchtop Β· Verified buyerWe finally have stopped buying bottle water and drinking out of plastic bottles. The water tastes so good we couldn't believe the difference in taste when drinking coffee & tea. We definitely will never go back to tap & bottle water again.
Diane K. Β· 9L Glass Benchtop Β· Verified buyerExtremely happy with the purchase of a new 9L Glass Benchtop Water Filter. We are all drinking much more water daily. We love not having the taste of βtown waterβ as my kids call it. Very easy to set up and looks beautiful on display in the kitchen. Highly recommended. Thank you Earths Water

How is the saving worked out?
We multiply the litres your household drinks by 365 and price them at the typical supermarket price of 74Β’ a litre. Then we take away the cartridges you would use in a year at $35 each. A cartridge lasts up to 350 litres or 3 months, whichever comes first. The saving is rounded to the nearest $10.
Does the saving include the filter itself?
No. The calculator compares bottled water with the cartridges you would use. The filter is a one-off cost, from $49 for the 2.4L jug.
How many plastic bottles does one cartridge replace?
Up to 700. Each Core 01 cartridge filters up to 350 litres, which is about 700 bottles of 500 ml.
Can I save more on cartridges?
Yes. Put your cartridges on subscription and save up to 14% on every one. A Core 01 cartridge is $30 on subscription against $35 one-off. Change, skip or cancel any time.
How often do I change the cartridge?
Every 350 litres or 3 months, whichever comes first. The second calculator on this page works it out for your household.
Which water filter should I start with?
For one or two people, a water filter jug or a 2.5L glass carafe. For a family, the 3.5L glass carafe or a 9 litre benchtop. For an office, the 9L Glass Benchtop or the 9L Eco Benchtop.
