Budget, contaminants, household size, Jean-Paul Barbar walks you through the four questions that determine the right water filter for your situation.
For Sydney homeowners choosing a water filter, the decision comes down to four questions: What is your budget? What do you most want to remove? Do you want drinking water only, or the whole house? And are you choosing a trustworthy licensed installer? The right answers to those four questions will point you to the right system every time. This guide is designed to help you answer them clearly, without jargon, without sales pressure, and with honest pricing from the start.
, Jean-Paul Barbar, Licensed Plumber (Lic. 461511C), Filters For YouWater filtration in Sydney ranges from $550 to $3,550 for supply and professional installation. Your budget is the first filter (no pun intended). Each price tier covers a different level of filtration. The good news is that even the entry-level system delivers a significant improvement over unfiltered tap water.
See the budget breakdown below for a clear picture of what each tier covers.
The most important question, because different technologies remove different things. Sydney tap water contains chloramines, fluoride, sediment, microplastics and trace heavy metals. Not all filter types remove all contaminants.
If fluoride removal is your priority: you need reverse osmosis. Nothing else removes fluoride effectively. If taste and chloramine removal is the priority and fluoride is not a concern, a twin-stage under-sink filter will do the job at lower cost.
An under-sink filter (twin-stage or RO) filters only the water at your kitchen tap. Everything else in your home, every shower, bath, laundry tap and dishwasher, remains on unfiltered water.
A whole house filter installed at the mains solves this. It filters every water outlet in the property. The trade-off is cost: whole house systems start at $3,150 vs $550 for an entry-level under-sink system. Many families choose both.
Any connection to your home plumbing requires a licensed plumber in NSW. An unlicensed installation voids your home insurance for related damage and exposes you to risk. Always verify the licence number, Jean-Paul's is 461511C, searchable on the NSW Fair Trading website.
Ask for a fixed-price quote that includes everything. A trustworthy installer will give you this without hesitation. Jean-Paul gives every customer a fixed price before any work begins.
Here is what each price tier covers for Sydney homeowners. All prices include supply and professional installation by a licensed plumber. No hidden costs.
Sydney tap water is safe to drink by regulatory standards, but it does contain several contaminants that many homeowners choose to filter. Here is what each system type removes.
| Contaminant | Twin Stage | Reverse Osmosis | Whole House |
|---|---|---|---|
| Chloramines (taste, smell) | Yes | Yes | Yes |
| Sediment | Yes | Yes | Yes |
| Microplastics | Yes | Yes | Yes |
| Fluoride | No | Yes (93–96%) | No |
| Heavy metals and lead | No | Yes | No |
| PFAS / dissolved contaminants | No | Yes | No |
| Bacteria | No | Yes | No |
The 5-stage RO gives you the most important health benefit, fluoride removal, at the most accessible price point. Excellent for renters too, as it is under-sink and leaves no visible trace.
Children are more sensitive to contaminants. The RO handles pure drinking water. The whole house filter means every bath and shower is also free of chloramines, particularly good for young skin.
The 7-stage RO gives you comprehensive contaminant removal including fluoride, heavy metals and dissolved contaminants. Step up to the Pure Luxe if you want real-time water quality monitoring.
A whole house filter removes chloramines from every shower and bath. Add a KDF shower filter in key bathrooms for targeted chloramine removal. This combination delivers the most noticeable skin improvement.
The quality of your installation matters as much as the quality of your filter. Here are the questions every Sydney homeowner should ask before booking any water filter installer.

For most Sydney families, a reverse osmosis system (Pure Plus+ from $840) is the best starting point. It removes fluoride, chloramines, heavy metals, PFAS and dissolved contaminants from your drinking water. If you want filtered water at every tap and shower in the home, add a whole house filter (Pure Home, $3,150–$3,550). A twin-stage under-sink filter (Pure Essential, $550.88) is the right choice if budget is the primary consideration and fluoride removal is not a priority.
Sydney tap water meets Australian Drinking Water Guidelines and is safe to drink by regulatory standards. However, it does contain chloramines (used for disinfection), fluoride (added at 1.0mg/L), trace microplastics and in some older areas, lead from aging pipes. Whether you choose to filter is a personal decision based on your health priorities. Many Sydney homeowners filter for improved taste, fluoride removal and peace of mind.
The Pure Essential twin-stage under-sink filter starts at $550.88 fully installed by a licensed plumber. It removes chloramines, sediment and improves taste and smell. It does not remove fluoride. If fluoride removal is important to you, the Pure Plus+ reverse osmosis system starts at $840 installed, and is Jean-Paul's most recommended system for health-conscious households.
It depends on your priorities. An under-sink filter (including RO) filters only the water at your kitchen tap, ideal if drinking water quality is the main concern. A whole house filter is installed at the mains and filters every tap, shower, bath and appliance in the home. For fluoride removal in drinking water, you need an under-sink RO. For better shower water quality, you need a whole house filter. Many Sydney families use both. See the full RO vs whole house comparison.
Ask: Are you a licensed plumber in NSW? Do you supply WaterMark certified equipment? What is the fixed price for supply and installation, all in? What is the annual maintenance cost? Do you offer a workmanship warranty? What does the filter actually remove, ask for the specific list. A trustworthy installer will answer all of these clearly without hesitation. Jean-Paul provides all of this information upfront before any booking is confirmed.
