Whole House Water Filters for Brisbane, Gold Coast & Major Australian Metros
Whole home water filters, also commonly called whole house water filtration systems, are installed on the main incoming water supply so water can be filtered before it reaches multiple taps, showers, bathrooms, laundries and appliances around the property.
The right whole house filter depends on water source, treatment goals, household flow demand, water pressure, pipe size, cartridge type and installation location. Town water and rainwater can require very different filtration setups.
Installed Today supplies whole home filtration systems across supported mainland Australian markets, with supplied and installed options available on selected systems in eligible Brisbane and Gold Coast service areas.
What Matters When Choosing a Whole House Water Filter?
What Is a Whole Home Water Filter?
A whole home filtration system is normally installed on the main water line before the water supply branches to fixtures throughout the property.
Depending on how the home is plumbed, filtered water can then be supplied to showers, bathroom taps, kitchen taps, laundries, toilets and selected appliances.
This is different from a drinking water filter or kitchen water filter , which usually treats water only at a specific kitchen outlet.
Whole House Water Filters for Town Water
Whole-home filtration for mains or town water is commonly designed around sediment reduction and carbon filtration.
Sediment Stage
Sediment filtration can capture suspended particles such as dirt, rust, sand, grit and other material above the cartridge's rated filtration size.
It is often used as the first stage so later cartridges receive cleaner water.
Carbon Stage
Activated carbon is commonly used where chlorine taste, odour and selected organic compounds are treatment priorities.
Actual reduction performance depends on the cartridge, flow, contact time and product specifications.
System Capacity
A whole-house system has to provide enough usable flow for showers, taps and appliances without creating excessive pressure loss.
Whole Home Filtration for Rainwater and Tank Water
Rainwater can require a different treatment approach from treated town water because water quality can be influenced by the roof catchment, gutters, first-flush setup, tank condition, sediment, pumps and how the water is used.
Depending on the water quality and intended use, a rainwater treatment system may include sediment filtration, additional filtration stages and UV water treatment .
Filtration should not be selected by assumption where water safety is uncertain. Water testing and an appropriate treatment design can be useful when the source water or specific contamination concern is not known.
Twin Stage vs Triple Stage Whole House Filters
| System | Typical Setup | Common Starting Point | What to Check |
|---|---|---|---|
| Twin Stage | Two cartridge stages | Commonly sediment followed by carbon for town-water filtration | Cartridge combination, flow capacity and pressure drop |
| Triple Stage | Three cartridge stages | Additional treatment where the water source or filtration goal requires another stage | What each stage actually does and whether it is required |
| Filter + UV | Pre-filtration followed by UV | Selected rainwater, tank-water and private-water applications | Water quality, pre-filtration, flow, power and UV servicing |
| Anti-Scale Setup | Filtration plus selected scale-control media | Properties wanting filtration plus scale-management features | Water chemistry, product claims and desired result |
Whole House Filter Flow Rate Is Critical
Whole-home filtration treats water used across the property, so flow capacity matters much more than it does with a small under-sink drinking-water filter.
A home may have showers, taps, washing machines and other fixtures operating at the same time. The filter system needs enough capacity to meet that peak demand without creating unnecessary pressure loss.
The current Installed Today range includes systems with substantially different flow capacities, so system sizing should be based on the household rather than simply choosing the lowest-priced housing.
- Number of bathrooms
- Number of occupants
- Peak simultaneous water use
- Existing water pressure
- Main pipe size
- Filter housing size
- Cartridge type
- Cartridge micron rating
Finer Filtration Is Not Automatically Better
A cartridge's micron rating indicates the particle size it is designed to filter according to the product specification.
A finer cartridge can capture smaller particles, but it can also create more resistance to flow or load more quickly where the incoming water contains significant sediment.
For whole-house filtration, the goal is to balance the required filtration with practical household flow, pressure and cartridge life. Choosing the smallest micron number without considering those factors can produce a poor result.
Does a Whole House Filter Remove PFAS and Other Chemicals?
Do not assume that every whole-home filter removes every contaminant. Filtration performance depends on the specific cartridge or treatment media, system design and operating conditions.
If PFAS reduction or another specific contaminant is an important treatment goal, compare the individual product's verified performance information and relevant certification or testing rather than relying on a general “whole house filter” description.
The same principle applies to heavy metals, pesticides, chloramine, fluoride and other specific water-quality concerns: select treatment around the actual contaminant and evidence for that product.
Scale Control Is Not the Same as Water Softening
Some whole-home filtration packages include anti-scale or scale-control treatment. These products are designed to manage scale according to the technology used and the manufacturer's specifications.
A scale-control cartridge should not automatically be described as a water softener. Traditional ion-exchange softening works differently by reducing hardness ions from the water.
If hardness or scale is the main reason for buying the system, consider the local water chemistry and decide whether filtration, scale control, water softening or a combination is actually required.
Whole Home Filters with UV Water Treatment
UV treatment uses ultraviolet light as a disinfection barrier and can form part of a broader whole-home water-treatment system for suitable water sources.
UV is not a replacement for sediment filtration. Water needs to meet the conditions required by the UV system, and pre-filtration is commonly used to help provide sufficiently clear water before the UV chamber.
UV systems also require an appropriate power supply, correct flow sizing, lamp servicing and suitable access for maintenance.
Where Should a Whole House Water Filter Be Installed?
Whole-house filters are normally installed near the incoming water line before the supply branches to the parts of the property being filtered.
A good installation position needs enough room for the system itself and enough clearance underneath or around the housings to remove them during cartridge replacement.
- Accessible incoming water line
- Safe cartridge-change clearance
- Suitable wall or mounting surface
- Isolation valves
- Bypass arrangement where required
- Weather and sunlight exposure
- Drainage where applicable
- Future service access
Exposed vs Enclosed Whole Home Filter Systems
Exposed Housings
Traditional housing systems keep the cartridges and filter heads visible and can provide straightforward access for inspection and cartridge replacement.
The installation location still needs to suit the materials and environmental exposure allowed by the product.
Enclosed Systems
Enclosed filtration systems place components inside a cabinet or purpose-built enclosure for a more finished appearance and additional physical protection.
Service access and ventilation requirements still need to be maintained.
Filter Wall Systems
Premium integrated systems can provide a cleaner installation finish with filtration components organised into a purpose-built assembly.
Compare flow, treatment stages and serviceability as well as appearance.
Whole House Filter Cartridge Replacement
Whole-home filtration needs ongoing maintenance. As cartridges collect sediment or use their treatment capacity, their performance and flow characteristics can change.
Replacement intervals depend on water quality, cartridge size, cartridge media, household consumption, incoming sediment and manufacturer recommendations.
Before buying a system, compare replacement cartridge availability, cartridge cost and how easily the installation can be serviced.
Can You Use Whole House and Kitchen Filtration Together?
Yes. Whole-home and point-of-use filtration serve different purposes and can be used together where appropriate.
A whole-house system can treat water entering the property, while a dedicated drinking-water or reverse-osmosis system can provide additional treatment at the kitchen.
This approach allows the whole house system to be sized around household flow while the drinking-water system can focus specifically on the water used for drinking and cooking.

Choose the Treatment First, Then Protect Household Flow
A good whole-home filtration system needs to do two things well: provide the treatment the water actually requires and maintain enough usable flow for the household.
Compare water source, treatment goals, cartridge media, flow capacity, pressure drop, pipe size, installation position, replacement cartridge cost and future service access before ordering.
Do not assume that every filter removes every contaminant. Check the individual product's stated filtration performance, certification and maintenance requirements where a specific contaminant is important.
Whole Home Water Filtration System FAQs
Common questions about choosing, ordering and installing whole home water filtration systems for cleaner household water, sediment reduction, taste and odour improvement, scale management, rainwater, tank water and mains water applications.
What is a whole home water filtration system?
A whole home water filtration system is installed on the incoming water line so filtered water can supply multiple outlets throughout the property. It is commonly used to help reduce sediment, chlorine taste, odour, discolouration and other water quality concerns depending on the cartridges, water source and system selected.
What type of whole home water filter do I need?
The right system depends on your water source, home size, flow rate, pressure, pipework, available installation space and what you want to improve. Some homes need a basic sediment and carbon system, while others may benefit from scale-management media, larger housings, UV treatment, rainwater filtration or a premium whole home filtration package.
Can a whole home water filter be installed on mains water?
Yes. Selected whole home water filtration systems can be installed on mains water. The correct setup depends on the home’s pipe size, flow demand, water pressure, installation location, cartridge type, service access and whether scale management or finer filtration is required.
Can a whole home water filter be installed on rainwater or tank water?
Yes, selected systems can be used for rainwater or tank water where the product is suitable. Rainwater and tank water setups should be checked carefully because filtration needs can depend on tank condition, roof collection, sediment load, pump setup, UV treatment requirements, cartridge type and how the water is used throughout the home.
Will a whole home water filter help with hard water or scale?
Some whole home systems include scale-management media designed to help reduce scale build-up. This is different from a traditional water softener. If scale, hard water marks or appliance protection are key concerns, choose a system designed for scale management and make sure it is suitable for your water source and household demand.
Will a whole home water filter improve taste and odour?
A suitable whole home filtration system can help improve taste and odour by reducing chlorine and other common water quality concerns depending on the cartridge type and water source. For dedicated drinking water performance, some homes also choose an under sink drinking water filter in addition to whole home filtration.
Will a whole home water filter remove sediment?
Yes, many whole home filtration systems include sediment filtration to help reduce dirt, rust, sand and other visible particles. The level of sediment reduction depends on the cartridge micron rating, system size, water quality, flow rate and how often the cartridges are maintained.
Will a whole home water filter affect water pressure?
Any whole home water filter can affect flow or pressure if it is undersized, blocked, incorrectly installed or fitted with cartridges that are not suitable for the home’s demand. The system should be selected based on flow rate, household usage, water pressure, pipework size and cartridge performance.
Where is a whole home water filtration system installed?
Whole home water filters are usually installed near the incoming water supply before the water branches off to the rest of the home. The exact location depends on pipework access, available space, service clearance, drainage, weather exposure, pressure requirements and whether valves or bypass pipework are needed.
Does a whole home water filter need a bypass valve?
A bypass valve can be useful because it allows water to continue supplying the home during cartridge changes, servicing or troubleshooting. Bypass valves, isolation valves and pressure limiting valves are not automatically included unless shown in the selected installation option or chosen as add-ons.
Do whole home water filtration systems need cartridge changes?
Yes. Whole home filtration systems use cartridges or treatment components that need replacement over time. Replacement frequency depends on the system, cartridge type, water usage, water quality, sediment load and manufacturer recommendations.
How often should whole home water filter cartridges be replaced?
Cartridge replacement timing varies by system, usage and water quality. Some homes may need more frequent changes if the water has high sediment, high usage, tank water, discolouration or noticeable taste and odour issues. Always follow the product recommendations and replace cartridges when flow or performance drops.
Can I buy a whole home water filtration system supply only?
Yes. Choose supply only if you already have a licensed plumber or suitable installer arranged. Supply-only pricing is for the water filtration product only and does not include installation, valves, fittings, pipework changes, pressure limiting valves, bypass valves, drainage, old system removal or compliance upgrades unless selected separately.
