Under Sink Water Filter
Top choice water filtration systems in Melbourne
Advanced Under Sink Filtration - Pure, Safe Water On Demand
If you’ve noticed your tap water has a strong chlorine smell, a strange aftertaste, or your kettle getting crusty way too quickly, you’re not imagining it.
An under sink water filter can quietly take care of all that. Installed neatly under your kitchen sink, it gives you cleaner, better-tasting water from your existing tap, without the mess of jugs or bench-top units.
No plastic bottles. Just good water, every time you turn on the tap.
Benefits of Under Sink Water Filtration
Choosing an under sink filter gives your family access to high-purity drinking water straight from the tap, with less waste, fewer contaminants, and peace of mind.Health
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.
Why Go With an Under Sink Filter?
If you’re not ready for a full home filtration system, a kitchen filter is a great place to start. It’s simple, compact, and does a lot more than people expect.
Here’s why Melbourne families choose under sink filtration:
- Cuts down chlorine, odour and that metallic taste
- Removes fine sediment and particles from ageing pipes
- Helps with dry skin and flare-ups (especially for kids)
- Makes your tea and coffee taste the way they should
- Saves money on bottled water
- Tucks away neatly out of sight
It’s one of the easiest ways to feel better about what you’re putting into your body, especially if you’re already mindful about food and health.

At PureFlow, we only install reverse osmosis (RO) systems because they offer the most complete under sink filtration available. While some filters reduce chlorine and improve taste, RO goes much further, helping reduce fluoride, nitrates, heavy metals, and more. It’s the level of protection we trust in our own homes, and the only solution we recommend to Melbourne families who want real peace of mind.

How Our Under Sink Filtration 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.

Under Sink Filters Compared
| Filter Type | Best For | Contaminants Reduced | Filter Lifespan |
|---|---|---|---|
| Benchtop Filter | Temporary setups, rentals, minimal use only | Basic reduction of chlorine, taste, odour — limited protection against sediment or contaminants | 3–6 months (frequent changes) |
| Twin Stage (Under Sink) | Entry-level filtration for taste and odour only | Chlorine, sediment, odour — does not address fine particles, bacteria or heavy metals | 6–12 months |
| Triple Stage (Under Sink) | Older plumbing, more visible sediment issues | Better sediment reduction, rust and odour — not suitable for bacteria or chemical removal | 6–12 months |
| Reverse Osmosis (Under Sink) | Families who want maximum protection for drinking water | Fluoride, chlorine, nitrates, heavy metals (lead, mercury), arsenic, pesticides, bacteria, PFAS, microplastics, taste, odour, sediment | 12–24 months (low maintenance) |
| Whole House System | Homes wanting full protection for showers, laundry, all taps | Chlorine, sediment, odour, rust, scale-causing minerals (setup dependent) — pair with RO for fluoride/bacteria removal | 12+ months (varies by setup) |
Is Under Sink Filtration Enough?
It’s a great start. Plenty of our customers begin with a kitchen filter, love the difference, and eventually upgrade to awhole house filtration system, especially when they realise how much chlorine’s in their shower and laundry too.
We’ll walk you through the pros and cons during your water test. No pressure. Just real advice based on your home and your water.

What Makes PureFlow Different?
PureFlow was started because of a simple problem: Monte (our founder) tested the water at home one day and didn't like what he found. Since then, we've helped hundreds of Melbourne families feel better about the water they're using every day.
When you work with us, you get:
- A free in-home water test, we come to you
- Clear, honest advice, no sales pitch
- Installation by licensed, local professionals
- Flexible payment options
- Full warranty on filters and installation
- Support from a small team that actually picks up the phone
We only install filters we use in our own homes. And we don't cut corners, not with the system, not with the install.
At PureFlow, we believe that Better Water is Better Living
We’re hands-on with everything we do. We only use filters we’ve tested ourselves, and we’re picky - if it’s not good enough for our own homes, we won’t offer it to you. Our systems are built for tough Aussie conditions, and every filter is checked and certified before it leaves our hands. We’re always looking for ways to improve, whether that’s smarter designs, better materials, or new ways to make things easier for busy families.

Under Sink Water Filter FAQs
How does an under sink water filter work?
What contaminants do PureFlow systems remove?
How often do I need to change the filters?
Can I install an under sink filter myself?
Will it reduce my water pressure?
While it may take a little longer to fill a jug, the trade-off is exceptionally clean, purified water that’s safe for drinking and cooking. It’s not designed for speed — it’s designed for purity.
Can I use my existing kitchen tap?
Standard kitchen mixers can’t be used with a reverse osmosis system. RO water needs to run through a dedicated filtered line, which is typically delivered via a separate tap installed next to your main mixer.
If you’d prefer not to have two taps on your sink, we also offer specialised 3-way mixer taps. These are designed with two handles, one for regular hot and cold water, and one for filtered RO water, all in a single, streamlined fitting.
We’ll walk you through both options during your free in-home assessment and help you choose what suits your kitchen setup and preferences.
