Whole House Water Filtration Systems
A whole house water filter treats every drop of water coming into your home. It's also called a point-of-entry filter. It installs at your mains water entry point, so it filters water going to your taps, showers, laundry, and garden.
This is different from a point-of-use filter, which only treats water at one tap. With a whole house system, every outlet gets filtered water.
Awesome Water Filters stocks whole house systems — from single-stage sediment filters to large triple-stage setups. Browse the full range below.
Who Needs a Whole House Water Filter?
Consider a whole house system if:
- You see sediment, rust, or discolouration at multiple taps
- You notice strong chlorine smell or taste in the shower and laundry, not just the kitchen
- Your property uses bore water, tank water, or a rural supply with variable quality
- You have skin or hair concerns linked to shower water
- You want pre-filtered water for appliances like hot water systems, dishwashers, or washing machines
Just want better-tasting drinking water? If you're on treated town water, a benchtop or undersink filter at the kitchen tap is often more practical and cheaper than a whole house system. See our Benchtop Water Filters or Under Sink Water Filters.
How to Choose a Whole House Water Filter
- Flow rate. Your system needs to deliver enough pressure and volume to every outlet at once. Bigger properties and higher-demand homes need higher-flow systems. Check the rated flow rate (litres per minute) before buying.
- Port size. Most residential systems use a 3/4" or 1" port. Match this to your mains pipe size.
- Number of stages. Single-stage systems handle one issue, like sediment. Twin and triple-stage systems combine sediment, carbon, and other media for broader treatment.
- Cartridge cost and schedule. Large cartridges usually last 3–6 months, depending on your water and usage. Factor ongoing cartridge cost into your decision.
- Installation. Whole house filters connect to your mains water supply. This work should be done by a licensed plumber — check the rules in your state or territory. Don't attempt to install a mains water system yourself.
WaterMark and Plumbing Compliance
Fittings connected to mains water in Australia may need WaterMark certification. WaterMark is Australia's compliance mark for plumbing and drainage products. Check your product documentation, and confirm with a licensed plumber whether WaterMark applies to your system before you buy or install.
FAQs
Do I need a licensed plumber to install a whole house water filter?
Yes. Whole house systems connect directly to your mains water supply. In Australia, this work generally needs a licensed plumber — check your state or territory's rules. Don't attempt a self-install on a mains water system.
How often do whole house filter cartridges need replacing?
Large cartridges are usually replaced every 3–6 months, depending on your water quality and daily use. Bore water or high-sediment supplies may need more frequent changes. Watch your water pressure — a big drop means the cartridge is clogged and needs replacing.
Will a whole house filter soften my water?
Usually not. Most sediment and carbon filters don't soften water — softening needs a specific ion-exchange process to reduce calcium and magnesium. If hardness is your main concern, a dedicated water softener suits you better than a standard whole house filter.
Can I use a whole house filter with tank or bore water?
Yes, as part of a treatment system. But the right filter setup depends on your water quality, which can vary a lot. Get your water tested first, then get advice on the right treatment for your source.
