ES5Q Whole House Wellness System Reviews

“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!”
Peter H.27 August 2024
“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.”

How often do you need to replace the ES5Q filter cartridges and what are the ongoing costs?
The ES5Q cartridges typically need replacement every 12 months, depending on water quality and usage.
We offer flexible cartridge replacement options:

Our 10‑Year VIP Support Package includes:
  • Annual replacement reminders.
  • Free express delivery of cartridges with live tracking.
  • Full coverage if cartridges are lost or damaged in transit.
Can I use ES5Q filtered water for drinking, cooking, and other household purposes?
Yes. The ES5Q uses a five‑stage filtration process that removes almost all chlorine, chemicals, sediment, and impurities, while restoring beneficial minerals. This makes the water safe and healthy for:
  • Drinking and cooking.
  • Bathing and showers.
  • Laundry and appliance use.
The result is cleaner, fresher‑tasting water throughout your home.
Does the ES5Q system remove sediment and heavy metals?
Yes. Our engineering design targets contaminants commonly found in treated and untreated water, including:
  • 75% of heavy metals
  • 92% of chlorine

  • 15% of fluoride
  • 80% of bacteria
The system also effectively removes sediment, rust, and suspended solids to improve water clarity and quality.

Our high‑flow design delivers outstanding water pressure while providing advanced filtration.
  • Up to 50 litres per minute flow rate.
  • Less than 5% reduction in flow for most household setups.
This means your whole‑home water remains powerful and consistent even with comprehensive filtration.
How will I know if my ES5Q system is working?
The ES5Q comes with built‑in pressure gauges as standard. This allows you to:
  • Monitor water pressure in real‑time.
  • Identify when filter replacement or maintenance is needed.
  • Protect your system from damage caused by blocked filters.
These gauges give peace of mind and ensure your investment is always performing at its best.
