Ensure safe drinking water from the tap, removing harmful contaminants such as chlorine, heavy metals, and chemicals.
Your family
Enjoy peace of mind with purified water for your family and pets. Healthier meals, better hydration, and reduced contaminants enhance well-being at home.
Environment
Reduce your reliance on bottled water, thereby decreasing plastic waste and your carbon footprint.
What is Reverse Osmosis?
Reverse osmosis (RO) is a water purification method that uses pressure to push tap water through a semi-permeable membrane. This membrane filters out microscopic contaminants, leaving you with exceptionally clean, clear water.
Reverse osmosis systems are popular with Australian households because they:
- Remove chlorine, fluoride, and nitrates
- Filter out heavy metals like lead and mercury
- Remove microplastics, bacteria, and viruses
- Improve taste, odour, and overall water quality
If you’ve noticed your tap water smells of chlorine, leaves limescale buildup, or tastes unpleasant, RO filtration could be the solution.
What our RO System Removes
Our RO systems remove up to 99.9% of 50+ known water contaminants.
Tested to Australian Standards.
| Inorganic Contaminants | Organic Chemicals | General Impurities |
|---|---|---|
| Aluminium — 98% | Adrazin — 98%+ | Chlorine — 98%+ |
| Arsenic — 98% | Aldrin — 98%+ | Fluoride — 99.9% |
| Barium — 95% | Benzene — 98%+ | Nitrates — 90% |
| Cadmium — 95% | Chloroform — 98%+ | Total Dissolved Solids — 95% |

How Our Reverse Osmosis System Works (5 Simple Steps)
Our RO systems are purpose-built for local water conditions and use six targeted stages to deliver outstanding filtration:
Stage 1
Sediment Filter
Captures dust, rust, silt, and other particles down to 5 microns, protecting the rest of the system.
Stage 2
Activated Coconut Carbon Filter
Reduces chlorine, chloramines, VOCs, and chemical by-products that affect taste and odour.
Stage 3
Reverse Osmosis Membrane (USA Made)
The core of the system. Filters contaminants as small as 0.0001 microns, including fluoride, bacteria, viruses, heavy metals, pharmaceuticals, microplastics and PFAS.
Stage 4
Alkalisation & Remineralisation
Reintroduces essential minerals like magnesium and calcium, raising the pH to a healthy alkaline level (~9.5) and improving taste.
Stage 5
Granular Activated Carbon
Gives your water a naturally fresh, sweet finish using high-grade coconut shell carbon.
The result? High-purity drinking water that’s crisp, balanced, and ideal for everyday use.
Is Reverse Osmosis Right for Your Home?
Reverse osmosis is one of the most advanced water filtration methods available, removing contaminants down to 0.0001 microns, or about 700,000 times smaller than a human hair. That means it can target what other systems can’t, including:
- Microplastics
- PFAS (forever chemicals)
- Pharmaceutical residues
- Fluoride, chlorine, and heavy metals like lead and mercury
It’s ideal for families who:
- Want the cleanest, safest water possible for drinking and cooking
- Are concerned about health impacts from tap or tank water
- Are dealing with unpleasant taste, odour, or limescale
- Prefer a more sustainable option than bottled water
If your goal is the highest purity water at the tap, reverse osmosis is the gold standard. However, if you're looking to filter water throughout the entire home (e.g. showers, laundry), a whole-house filter system may be more suitable.
Not sure what’s right for your home? We offer free water assessments across Melbourne to help you decide.
Reverse Osmosis (RO) System versus Whole House Water Filter
| Feature | Reverse Osmosis (RO) | Whole House Water Filter |
|---|---|---|
| Coverage | Point-of-use (usually one tap) | Point-of-entry (entire house) |
| Contaminant Removal | Removes up to 99% of dissolved solids, heavy metals, fluoride, bacteria, viruses, microplastics & pharmaceuticals | Reduces sediment, chlorine, chemicals; some models (Like PureFlow's) also reduce heavy metals, lead, VOCs and scale |
| Water Taste & Purity | Ultra-pure, often mineral-free (unless remineralised) | Improved taste and odor; keeps healthy minerals |
| Drinking Water Quality | Excellent | Good (not as pure as RO) |
| Whole-Home Protection | No | Yes |
| Bathing/Laundry/Kitchen Use | Only protected at filtered tap | All water in house is filtered |
| Installation and Cost | Moderate cost for each tap/sink system | Can be more affordable; requires less maintenance |
| Maintenance | Filter/membrane changes; some water waste | Filter changes; generally less maintenance |
| Water Waste | Produces wastewater (1.5L+/- waste per 1L filtered) | No wastewater |
| Preserves Essential Minerals | No (removes minerals, unless remineralised) | Yes |

Tailored for Melbourne Water Conditions
From high-chlorine water in inner suburbs to calcium-heavy supplies in areas like Geelong, Werribee, and the Mornington Peninsula - we’ve seen it all.
Our RO systems are custom-configured based on your postcode and plumbing setup. And because we’re Melbourne-based, we know what works - and what doesn’t.
Options to Suit Every Home
We offer both under sink reverse osmosis systems for ultra-pure drinking water at your kitchen tap, and setups often referred to as “whole house reverse osmosis filters”. While true whole-house RO isn’t always practical, we can combine whole house filtration with under sink reverse osmosis to give you clean water throughout your home, plus high-purity water where you need it most.
Not sure what’s right for your space? We’ll help you work out what size system suits your household, whether it will fit under your sink, and how often the filters need replacing. Our team makes the process clear and stress-free from the start.

Reverse Osmosis Water Filter FAQs
How does a reverse osmosis system work
Reverse osmosis systems use pressure to force water through a semi-permeable membrane. This process removes contaminants like fluoride, lead, chlorine, and PFAS, delivering clean drinking water through a multi-stage filtration system.
What is the difference between a RO and a whole house water filter?
Reverse Osmosis: Point-of-use, filters at microscopic level, removes fluoride, PFAS, heavy metals.
Whole House Filter: Point-of-entry, improves general water quality, great for showering and appliances.
Do I need both a RO system and a whole house filter?
It depends on your needs. Many Melbourne families choose both, a whole house filter for general water use and an RO system for drinking and cooking.
Is a whole house water filter or RO system better for Australian homes?
Each serves a different purpose. Whole house filters improve water for showers, laundry, and appliances. RO systems provide ultra-pure water for drinking – ideal for health-conscious households.
Does RO remove fluoride, lead, or PFAS from drinking water?
Yes. A properly designed RO system reduces fluoride, lead, PFAS, and other harmful contaminants down to microscopic levels.
Can I shower or bathe in reverse osmosis water?
You could, but it’s not practical. RO systems are typically used for drinking and cooking water. For showering, a whole house system is more appropriate.
How often do I need to replace filters in a reverse osmosis system?
Most RO filters need changing every 6–12 months, depending on usage. However, if paired with a high quality whole home filtration, filter lifespan can be extended.
What are the ongoing costs of RO vs whole house systems?
RO systems have low annual costs for filter replacements. Whole house systems may be slightly higher depending on capacity, but both are economical compared to bottled water.
Do RO water filters make water taste better?
Yes. Reverse osmosis systems significantly improve water taste by removing chemicals, odours, and impurities that affect flavour.
Will a RO water filter remove all minerals & nutrients from my water?
RO systems do reduce minerals, but the PureFlow RO system adds them back with a remineralisation stage for better health and taste.
Are reverse osmosis filters easy to install?
Yes, most systems are installed in a few hours with no major changes to your plumbing.
Can a RO water filter help with skin conditions or allergies?
Many customers report improvements in skin irritation, eczema, and allergies after switching to filtered water, especially with whole house systems.
