3-Stage Whole Home Filtration
Protect every tap in your home with clean, filtered water from the moment it enters your plumbing. Armour Whole House Water Filter Systems reduce chlorine, sediment and unwanted contaminants, delivering better showers, better tasting water and long term protection for your appliances and pipes.
Whole House Water Filter: Clean Water From Every Tap in Your Home
Imagine turning on any tap in your home and knowing the water from every tap is filtered, fresh, and free from contaminants. That is exactly what a whole house water filter delivers. Unlike under-sink or countertop units that only treat water in one spot, a whole house filtration system is installed at the point where your mains supply enters the property, so every outlet, every shower, every appliance, and every glass of drinking water benefits from genuine filtration.
At Armour water, we supply and install premium whole house water filter systems across Australia. Our range is designed to suit all types of homes and water supply conditions, from chlorinated city mains to sediment-heavy tank or bore water. If you want clean water running through every pipe in your home, you are in the right place.
We understand that choosing a water filtration system is a significant decision. That is why we take the time to understand your needs, test your water if required, and recommend a solution that genuinely delivers. Our customers tell us the biggest benefit of switching to a whole home water filtration system is the peace of mind it provides. No more wondering what is in the water. No more buying bottled water. Just reliable, high-quality filtered water throughout your entire home, every single day.
What Is a Whole House Water Filtration System and How Does It Work?
A whole house water filter system is a point of entry filtration setup that connects directly to your main water supply line. All water entering your home passes through the system before it is distributed to taps, showers, bathrooms, the laundry, and appliances. This is what makes it so effective: rather than filtering water at just one outlet, it ensures filtered water reaches every corner of your property.
These water systems typically use multiple filtration stages working in sequence. Each stage targets a different category of contaminant, so by the time water reaches your tap, it has passed through a comprehensive treatment process. The result is noticeably better water quality across the board, whether you are drinking, showering, cooking, or running a load of washing.
One of the standout features of a whole home water filtration system is the way it protects your entire plumbing network. When untreated water full of sediment, heavy metals, and minerals flows through your pipe’s day after day, it causes slow but steady damage in the form of scale build up, corrosion, and blockages. A quality house filtration system addresses this at the source, keeping your plumbing, hot water unit, and appliances in much better condition over time.
The Three-Stage Filtration Process That Protects Your Whole Home
Our whole house water filter systems use a proven three stage filtration approach to deliver genuinely clean water at every outlet. Here is how each stage works and why it matters.
Stage One: Sediment Filtration for Dirt and Particles
The first stage uses a sediment filter to remove large particles from your water supply. Sand, silt, rust flakes, dirt, and suspended solids are captured before reaching taps or downstream filtration stages. This stage protects overall water quality and extends the life of other filter cartridges. A quality sediment filter forms the foundation of any effective house water filter system, preventing premature clogging and maintaining strong flow throughout the system.
KDF-55 and Coconut Carbon Filtration for Chemicals and Metals
The second stage uses a KDF-55 and coconut carbon filter — the workhorse of the system. KDF-55 media is specifically engineered to reduce heavy metals including lead, mercury, and iron, and to inhibit bacterial growth inside the filter housing. Combined with premium coconut activated carbon, this stage handles chlorine, chloramines, chemical byproducts, and odours. This stage greatly improves how water tastes and smells while reducing your family's daily exposure to chemical disinfectants in your water supply.
Stage Three: Limescale Reduction and Carbon Polishing for Scale and Taste
The third stage uses limescale reduction media combined with a carbon polishing filter to protect your home and refine your water quality. Hardness minerals like calcium and magnesium are conditioned to reduce scale buildup on taps, shower screens, and inside your hot water system. The carbon polishing stage removes any residual odour and ensures the cleanest possible taste before water reaches you. This final stage protects plumbing and appliances while extending the life of your whole house water filter system.

Installation, Flow Rate, and Ongoing Maintenance
Professional Installation for Reliable Performance
Our qualified technicians install whole house water filtration systems at the main entry point, integrating the system neatly into your existing plumbing. This ensures every tap in your home receives clean filtered water.
Each system is carefully sized to maintain the correct flow rate across the entire property. We test the installation thoroughly and include a bypass valve so the system can be serviced without interrupting your water supply. Our team works with houses, townhouses, units, and rural properties, making the installation process simple and stress free.
Filter Replacement Schedule and Ongoing Filtration Care
Keeping your whole house filtration system performing properly requires regular filter replacement and servicing. Sediment cartridges are usually replaced every six months, carbon/KDF every 12 months, depending on usage and water quality.
We provide a filter replacement reminder service and can deliver cartridges directly to your door. Routine maintenance keeps your water filtration system operating efficiently, maintains the correct flow rate, and ensures contaminants continue to be effectively removed from your household water supply.
Choosing the Right Whole House Water Filter System for Your Home
No two homes are the same, and neither are their water quality challenges. The right water filtration system depends on your water source, whether mains water, tank water, or bore water, as well as household size, outlets, and specific contamination concerns. For municipal mains water, removing chlorine and chloramine is usually the priority, while tank and bore water often require solutions for sediment, bacteria, and microbial contamination, sometimes with UV purification. Proper flow rate is also essential to maintain water pressure across the home. Our team designs the right home water filter system based on testing, usage and budget to ensure reliable performance and long term value.

Frequently Asked Questions About Whole House Water Filters
The key difference lies in where the water filtration system is installed and the extent to which it covers your home. An under-sink filter is a point of use device that only treats water at a single tap, usually the kitchen sink. A whole house water filter, by contrast, is installed at the point of entry where the mains water supply enters your property. This means every outlet in your home, including showers, bathroom taps, the laundry, and outdoor taps, receives filtered water.
For households that want comprehensive coverage and peace of mind throughout the entire home, a whole house filtration system is the superior choice. It protects your appliances from scale buildup, improves the quality of your shower water, and ensures your drinking water at every tap meets a consistently high standard. Under-sink units have their place, but they simply cannot match the breadth of protection that a point of entry house water filter system delivers. If whole home protection and genuine water quality improvement is your goal, a whole house system is the right investment.
This is a common concern, and the short answer is: not if the system is correctly sized. The flow rate of a whole house water filter system needs to be matched to your household's peak water demand. When we size a system for your property, we consider the number of bathrooms and outlets, as well as your household’s typical daily usage patterns. A system with an adequate flow rate will not cause any noticeable drop in water pressure.
Where pressure issues do arise, they are almost always the result of an undersized system or a filter that is overdue for filter replacement. A clogged sediment filter cartridge, for instance, will restrict flow rate significantly. This is why we recommend staying on your maintenance schedule and replacing cartridges at the intervals we recommend. Our house filters are designed for real Australian homes with real water usage demands, and our team always ensures your selected system has the flow rate capacity to comfortably handle your household's needs.
The service frequency for your house filtration system depends on the type of system you have, your household's water usage, and the quality of your incoming water supply. As a general guide, the sediment filter stage typically requires a cartridge change every six months, while the carbon/KDF stage requires a change every 12 months. If your water supply has high sediment loads, such as bore or tank water, you may need to service the first stage more frequently.
We provide all our customers with a recommended filter replacement schedule at installation and offer reminders to ensure nothing slips through the cracks. Staying on top of maintenance is what keeps your home water filters performing at their best, and your water tastes consistently great. Neglecting maintenance does not just affect taste and odour. It can also allow contaminants including heavy metals and sediment to pass through to your taps, defeating the purpose of having a water filtration system in the first place.
Yes, absolutely. Our multi-stage house water filter system includes a dedicated KDF media stage that is specifically designed to target heavy metals including lead, mercury, iron, copper, and arsenic. KDF technology works through a chemical reaction that converts dissolved heavy metals into insoluble compounds that are then captured within the filter media. This makes it highly effective for homes where heavy metals are a concern, whether due to an ageing plumbing network, a corrosive water supply, or local groundwater conditions.
For homes with very high levels of heavy metals, we may also recommend installing a reverse osmosis stage at the kitchen sink for drinking water, providing an additional layer of protection where it matters most. Our team will always conduct or recommend a water test before finalising a system recommendation, so you know exactly what your water supply contains and which technologies are most effective for your situation. The goal is always clean water at every outlet and genuine peace of mind for your household.
Great question, and it is more common than you might think. If your water tastes unpleasant, it could be coming from either your municipal water supply or from your home's internal plumbing. A strong chlorine taste or taste and odour issue is typically a water supply problem, originating with the treatment process used by your water authority. A metallic taste, on the other hand, is more often a sign that your pipes are leaching heavy metals such as copper or lead into the water as it travels through your home.
The good news is that a quality whole house water filter addresses both scenarios effectively. Whether the issue is at the mains or inside your walls, a properly specified water filtration system will catch contaminants before they reach your taps. We strongly recommend a professional water test to identify the specific cause, as this allows us to specify the most effective home water filters for your situation. Once installed, our customers consistently report that water tastes noticeably better, and that the improvement in water quality across the whole home gives them the peace of mind they were looking for.
