Whole House Water Filtration Systems
Whole house water filters — also called point-of-entry filters — are installed at the mains water entry point to your property, treating all water that flows through your taps, showers, laundry, and garden connections. Unlike point-of-use filters that treat water at a single tap, a whole house system means every outlet in your home delivers filtered water. Awesome Water Filters stocks a range of whole house filter systems, from single-stage sediment filters through to large-capacity triple-stage configurations.

Who Needs a Whole House Water Filter?
Whole house filtration is typically considered when:
- There is sediment, rust, or discolouration affecting multiple taps throughout the home
- Strong chlorine taste or odour is noticeable from the shower and laundry — not just the kitchen tap
- The property is on bore water, tank water, or a rural supply with variable quality
- Skin or hair concerns are linked to shower water quality
- There are appliances — such as hot water systems, dishwashers, or washing machines — that benefit from pre-filtered water
For most households on treated town water who simply want better-tasting drinking water, a benchtop or undersink filter at the kitchen tap is often more practical and cost-effective than a whole house system. If your concern is primarily drinking water, see our Benchtop Water Filters or Under Sink Water Filters.
How to Choose a Whole House Water Filter
Key factors to consider:
- Flow rate: Whole house systems must deliver adequate water pressure and volume across all outlets simultaneously. Larger properties and higher-demand households need higher-flow systems. Check the rated flow rate (litres per minute) before purchasing.
- Port size: Most residential whole house filters use a 3/4" or 1" port. Match the port size to your existing mains water pipe diameter.
- Number of stages: Single-stage systems typically address one main concern (e.g., sediment). Twin and triple-stage systems combine sediment, carbon, and sometimes additional media for broader treatment.
- Cartridge replacement schedule and cost: Large-format whole house cartridges typically last 3–6 months depending on your water quality and usage. Factor in ongoing cartridge costs when comparing systems.
- Installation: Whole house filters must be installed on your mains water supply line. This work requires a licensed plumber in all Australian states and territories. Do not attempt self-installation of a mains water system.
WaterMark and Plumbing Compliance
Any fitting or device connected to a mains water supply in Australia may be subject to WaterMark certification requirements. WaterMark is Australia's regulatory compliance mark for plumbing and drainage products. Check the product documentation and confirm with a licensed plumber whether WaterMark certification applies to the system you're considering before purchase and installation.
Frequently Asked Questions
Do I need a licensed plumber to install a whole house water filter?
Yes. Whole house water filter systems are connected directly to your mains water supply. In all Australian states and territories, work on mains-connected plumbing must be carried out by a licensed plumber. Do not attempt self-installation of a mains water system.
How often do whole house filter cartridges need replacing?
Large-format whole house cartridges are typically replaced every 3–6 months, depending on your water quality and daily usage. Properties on bore water or high-sediment supplies may need more frequent cartridge changes. Monitor water pressure — a significant drop indicates the cartridge is clogged and needs replacing.
Will a whole house filter soften my water?
Most whole house sediment and carbon filters do not soften water — water softening requires a specific ion-exchange process to reduce calcium and magnesium hardness minerals. If water hardness is your primary concern, a dedicated water softener or conditioner is more appropriate than a standard whole house filter.
Can a whole house filter be used with a tank or bore water supply?
Whole house filters can be part of a treatment system for tank or bore water, but the appropriate filter configuration depends on your specific water quality — which can vary significantly. Have your water tested before selecting a system, and seek advice on the appropriate treatment approach for your source water.
