Choosing The Right Water Filter

Our Systems
Tell Us The Goal. We'll Match The System.
Filtration is not one product. Pick what you actually want to change and the right setup is usually obvious.
-
Under-Sink Drinking Water
I want better drinking water. Point-of-use, in the kitchen cupboard, with its own dedicated filtered water tap. Carbon block reduces chlorine taste and odour. Cartridges typically rated around 6 months.
-
Whole-House Filtration
I want it at every tap. Point-of-entry on the incoming supply: a sediment stage for rust, sand and silt, activated carbon for chlorine taste and odour, sized to your flow rate and water pressure.
-
Reverse Osmosis
The highest level of drinking water treatment. Needs adequate incoming pressure and cupboard space for the manifold plus an 8 L tank. We'll talk you out of it if carbon suits you better.
-
Commercial Filtration
Offices, cafes, restaurants, commercial kitchens, gyms and retail. Specified from peak flow and daily volume, feeds coffee machines, beverage and ice equipment, serviced around your trading hours.
-
Replacement & Servicing
Including systems we did not install. Sediment, carbon, RO pre-filters and membranes, with O-ring, seal and leak checks every visit. Send a photo of the housings and we'll identify the cartridges.

Why Choose Us
Installed Right, Backed Properly
Anyone can sell you a filter online. What you get from Water Filtration Sydney is the sizing, the licensed plumbing and the support after the van leaves.
Connecting filtration into a drinking water supply is plumbing work, and NSW requires a licence for it, residential or commercial.

Running Cost Upfront
Cartridge costs before you commit
You get the system spec, the fixed installed price and the replacement cartridge costs before you commit. No surprise at the first service.
Sound Familiar?
Most Filtration Regrets Start Before Anyone Turns a Tap
Almost every system we are called out to fix was bought correctly and specified badly. Here is where it usually goes wrong.
The Taste Never Changed
A filter was fitted, but the media was wrong for the job. Chlorine taste and odour need an appropriately specified activated carbon stage, not just more stages on the box.
The Pressure Dropped
The system was sized below the household's peak flow. Everyone blames the filter; the real cause is a housing chosen without checking incoming pressure first.
Nobody Mentioned The Cartridges
The install price looked sharp until the first replacement. You should know the cartridge cost and the change interval before you say yes, not eighteen months later.
Compliance & Workmanship
Why Professional Installation Matters
- Isolation valves either side, so cartridge changes take minutes
- Correct sizing so the system does not throttle your water pressure
- Servicing clearance to actually drop the sumps at change time
- Leak prevention through correct fittings and pressure-tested joints
- WaterMark certification as the National Construction Code requires for listed plumbing products

Our Reviews
Installs You Can Inspect. Reviews You Can Check.
5.0 out of 5 on Google. Neat pipework, isolation valves either side, and housings mounted where the sumps can actually be dropped at change time.
Called Ahead, Helpful And Pleasant
Excellent service tech called before arrival and was very helpful and pleasant.
Carmel Bhatty
Neat, Swift Under-Sink Installation
I recently purchased and had installed the 6-stage water filtration system. The technician communicated clearly his arrival time. The system was installed very neatly in the under-sink cupboard, maximising the remaining space. The technician was an absolute delight throughout and installed the system very swiftly.
Daniel Colantoni
Happy With My New Water Filter
The technician came out and installed my water filter and I'm very happy with it, highly recommend!!
Lucy Sun
Filtration brands we install and service, so replacement cartridges stay available for the life of the system.
Before You Decide
The Questions We Get Asked Most
Straight answers on price, cartridges, pressure and which system suits your property. If yours is not here, pick up the phone and ask.
How much does water filter installation cost in Sydney?
It depends on the system, the plumbing configuration and where the equipment mounts. An under-sink filter in an accessible cupboard is a different job to a whole-house system on an external wall. We quote the system and installation as one fixed price, with the cartridge costs shown alongside it. Our Whole Home + Kitchen RO Bundle is $5,500 installed for a standard installation.
Am I committing to anything by asking for a quote?
No. The quote is free, there is no call-out fee to prepare it, and there is no obligation once you have it. You get the system specification, the installed price and the ongoing cartridge costs so you can compare us properly against anyone else.
Whole-house filter or under-sink filter?
Whole-house is point-of-entry: every tap, shower and appliance gets filtered water. Under-sink is point-of-use: one dedicated tap for drinking and cooking. If taste at the kitchen bench is the goal, under-sink is usually the practical choice. Many Sydney homes run both.
What if the system doesn't fix what I wanted fixed?
That is why we assess before we quote rather than selling from a catalogue. We tell you what a given system is designed to reduce and what it is not, so the expectation is set before you spend anything. If our workmanship is ever the problem, the lifetime labour warranty means we come back and fix it.
Is reverse osmosis right for every home?
No. It needs adequate incoming pressure, cupboard space for the manifold and storage tank, and it sends some feed water to drain. If you mainly want less chlorine taste and odour, a properly specified activated carbon filter often does the job with simpler servicing, and we will say so.
How often do cartridges need replacing, and what does that cost?
By the manufacturer's rated capacity and your usage. Sediment and carbon block cartridges are commonly rated around six months; some silver-activated carbon cartridges around twelve months or a rated litre capacity; RO pre-filters six to twelve months, with the membrane less often. Your quote lists the cartridges your system takes and what each one costs, so there is no surprise at the first service.
Will a filter drop my water pressure?
A correctly sized system should not. Pressure complaints almost always trace to a system sized below the property's peak flow, or cartridges left in past their rated capacity. We check incoming pressure and estimate peak demand before specifying a whole-house system.
Do you install commercial systems and service existing ones?
Yes to both. We install commercial filtration for offices, cafes, restaurants, commercial kitchens, gyms and retail premises, specified from peak flow, daily volume and the equipment being fed. We also replace cartridges in systems installed by someone else. Send a photo of the housings and we will identify what it takes.
