Home Water Filtration System Reviews

Researched A LOT

I did A LOT of research before choosing GW (13 companies). They had all the health features that mattered at the best price, that simple. The sales department (Hayden) was also the least 'salesy' & most customer focused/factual. REALLY happy with our purchase & loving our living water!

Review Great Water Australia Complete Home Water Filter System

Review: Great Water Australia Complete Home Water Filter System
After careful consideration and comparison of several brands, I chose the Great Water Australia Complete Home Water Filter, and I can confidently say it has exceeded expectations. From the outset, the customer service was professional and responsive, ensuring a smooth installation process. The unit itself is robust, well-designed, and seamlessly integrated into our home water system. What impressed me most is the noticeable improvement in water quality. The filtered water is visibly clearer, tastes noticeably cleaner, and is free of the chlorine odour and sediment we previously experienced. Whether for drinking, showering, or cooking, every tap in the home now delivers high-quality water that feels softer on the skin and safer for the family. Additionally, knowing that it removes a wide range of impurities—while retaining essential minerals—gives me peace of mind regarding long-term health and plumbing protection. I highly recommend Great Water Australia for anyone seeking a reliable, Australian-made whole-house water filtration system that delivers on performance, durability, and customer support

Pure water taste again

Since being switched to the Albany water supply here in WA the water was so full of calcium. It was building up on the shower screen and was visible inside the kettle (had just bought a glass kettle) so all the particles were visible while the water boiled. Now that we have the full house system all that has gone, no more mineral build up, shampoo lathers again, drinks taste right. I would recommend this system to everyone

Glen Dickinson15 Dec 2024

Good enough that our neighbours want one

We ordered the Wellness Whole House System. At the time, it was not in stock, so we had to wait a few weeks before it was installed. During the process, we were kept up to date with progress. We were happy that they could arrange an installer for us living in regional Queensland. The installer did a fantastic job and mentioned that he had installed a few of these systems in the area, and they are very reliable. We have gone from hard chlorinated water to soft water we enjoy drinking. Our neighbours are now looking at ordering their own systems.

FAQs

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:
  • Wellness Cartridge Pack — $395/year, includes advanced volcanic mineral media.
  • Standard Cartridge Pack — $295/year, without wellness mineralisation.
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
  • 92% of pesticides and herbicides
  • 15% of fluoride
  • 80% of bacteria
The system also effectively removes sediment, rust, and suspended solids to improve water clarity and quality.
Will there be any water pressure reduction with the ES5Q system?
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.
Are ES5Q systems backed by a warranty?
Yes. The ES5Q comes with a 2‑Year Warranty on system components, supported by our 10‑Year VIP Support Package, which includes:
  • Friendly cartridge replacement reminders.
  • Access to the latest micron filtration technology.
  • Free delivery of replacement cartridges.
  • Comprehensive service guarantee covering parts and labour.
This gives you confidence that your system is protected for years to come.
Why choose the ES5Q for house water filtration?
The ES5Q offers a unique combination of:
  • Advanced multi‑stage filtration for chemical and contaminant removal.
  • Volcanic mineral revitalisation for natural taste and balance.
  • Auto Backwash protection for low maintenance and longer filter life.
This makes it one of the most effective and convenient whole‑house filtration systems available.
What maintenance is required for the ES5Q system?
Maintenance is straightforward thanks to the system’s design:
  • Annual cartridge replacement — reminders available through our VIP Support program.
  • Auto Backwash cycle — reduces manual cleaning.
  • Routine visual inspections every 3–6 months to check for pressure changes or leaks.
These simple steps ensure your ES5Q system continues to deliver high‑quality water for years.
What’s the best Home Water Filtration System in Australia? The ES5Q Home Water Filtration System is one of Australia’s most advanced and trusted whole-house systems. It delivers pure, mineral-balanced water to every tap using volcanic mineral technology, Auto Digital Backflush protection, and a Vortex Softener. With 5-stage super filtration and 316 Marine Grade Stainless Steel housing, it removes impurities, softens water naturally, and revitalises it with essential minerals — ensuring cleaner plumbing, softer skin, and fresher-tasting water throughout your home.
