What Customers Say

“Great service and support. Great Water Filters send me an annual reminder when my filters are due, they keep records so I get the right filters at the right time.
Support is unparalleled. I get help when I need by phone and in the event of something going wrong, Great Water Filters had a representative from WA to help resolve the issue in one visit.
Phone support, ordering additional filters (for showers), and response times are excellent. I recommend them highly!”

“Quality finishes, water and customer service. From meeting Paul at the Home Expo, to engaging with Levon to help plan and work through all our queries and ultimately to Shannon implementing the system we're delighted with the result and enjoying the filtered water at every tap point in our home...and without loss of pressure. Thanks Great Water Team!”

Yianni S.27 August 2024

“Fantastic experience from start to finish. No pushy sales like the other company we enquired with. We kind of knew what we wanted, and any questions we had were answered honestly and concisely. We’re loving having filtered water throughout the whole house with no noticeable water pressure loss. Thanks for being such a wonderful company to deal with. I have already recommended the whole home filtration system to several of our family and friends”

Christie K.27 August 2024

“Very happy with the quality of the product and the service. We have gone from having dirty, hard water (awful town supply!) to clean water that feels soft after the installation of a whole-house filter. The whole process was quick, taking less than a week from my first approach to Great Water to the filter being installed. The plumber assigned was friendly and professional. A very small amount of seepage we had after installation was fixed within a day after one text message to Great Water. While the price may put some off, we see it as a saving on the jug filters we no longer need to buy, and on the damage the old hard water used to do to the bathroom, kitchen and cars. I would definitely recommend Great Water's household filter system.”

FAQs

What does the ES3 Reverse Osmosis system remove?

The ES3 removes up to 99% of contaminants, including:

Fluoride, chlorine, and pesticides
Heavy metals such as lead and mercury
Bacteria and viruses (E. coli, Salmonella, Hepatitis A)
Organic compounds, odours, and chemicals that affect taste

With a filtration capacity of 0.0001 microns, the ES3 delivers exceptionally pure water for everyday use.

Can I use RO water from the ES3 for cooking? Yes. ES3-purified water is free from impurities, which enhances the flavour of food, tea, and coffee. Many households also prefer it for baby formula and health-conscious cooking.

How often should I replace ES3 cartridges and membranes?

Cartridges: every 10–12 months (depending on water quality and usage)
RO membrane: every 24 months for consistent performance

We provide reminders and easy access to replacement kits to keep your ES3 running at its best.

Will the ES3 system reduce my water pressure? The ES3 is designed to minimise pressure loss, typically reducing flow by less than 5%. This ensures strong and reliable performance at your kitchen tap.

Can the ES3 be used with all water sources?

Yes. The ES3 is compatible with:

Town water (mains supply)
Tank water
Bore water

For tank or bore water, additional pre-filtration or UV treatment may be recommended depending on local conditions.

What maintenance does the ES3 require?

Routine care is straightforward:

Replace filters and membrane as scheduled
Periodically clean the system
Check performance indicators to ensure optimal water quality

Our team provides ongoing support, reminders, and replacement parts.

Does the ES3 include a remineralisation stage?

Yes. The ES3 features a Wellness Re-mineraliser, which adds back essential minerals such as:

Calcium
Magnesium
Sodium
Potassium

This restores taste, balances pH, and supports overall health.

Is the ES3 Reverse Osmosis system certified for safety and quality? Yes. The ES3 is built with high-grade components and undergoes rigorous testing to meet strict safety and performance standards. It is trusted across Australia for reliable water purification.

What’s the best whole house water filter in Australia? The ES5Q Whole House Water Filter is one of Australia’s most trusted systems, providing mineral-balanced, crystal-clear water to every tap. Its five-stage filtration removes impurities, softens water, and restores beneficial minerals for healthier hydration and cleaner plumbing.
