What's really in your water?

You turn on the tap expecting clean, safe water. But what's actually flowing through your pipes might surprise you.

  • Microplastics

    Tiny plastic particles from broken-down plastics and fibres. Some are small enough to pass through standard filtration systems.

  • Sediment & infrastructure debris

    As water moves through ageing pipes, it collects sand, silt, rust flakes, pipe scale and suspended particles.

  • Disinfectant residuals

    Chlorine and chloramine help keep mains water safe, but can affect taste and odour.

  • Dissolved minerals

    Calcium, magnesium and trace metals naturally found in Australian water that contribute to hardness and scale build-up.

How Whole House Water Filters Work

A whole-house water filtration system is installed on your home’s main water supply, filtering incoming water before it is distributed to your taps, showers and appliances.

The filtration system uses multiple stages to treat your household water before it flows throughout the home.

Find the Right Whole-Home Water Filtration System

Whole House Water Filter vs Tap Water Filter

Frequently asked questions

  • Unlike a small jug or a single tap filter, a whole-home system is installed at your property’s main water entry point. It uses a multi-stage process—including high-grade carbon blocks and sediment filters—to strip away chlorine, heavy metals, and bacteria before the water ever enters your internal plumbing. This ensures every drop from every shower, toilet, and tap is purified.

  • Most whole-home systems fall in the $3,000–$5,000 range, depending on the size of your home, your water source, and the level of filtration required - town water, tank, and bore water all have different needs. With our $0 upfront payment plan and 0% interest, you don't need to pay anything to get started. A Smart Energy specialist will give you an exact quote tailored to your home during your free consultation.

  • Once your 90-day no-payment period ends, our flexible weekly plans typically start from around $25 per week - roughly $3.50 a day. Your exact weekly amount depends on the system you choose and the payment term that suits your budget, and we'll walk you through every option transparently so there are no surprises.

  • Every Smart Energy installation is backed by a 5-year workmanship warranty, fully covering the quality of the install itself. If you keep your filters serviced through us, you'll also receive an additional 12-month extended product warranty.

  • Our high-capacity systems are designed for Australian conditions and typically require a filter change once every 12 to 24 months, depending on your household's water usage. Smart Energy makes maintenance easy; we’ll track your system’s life and reach out when it’s time for a quick service, ensuring your water quality never dips.

  • Yes. While Australian council water is "safe," it is heavily treated with chlorine and chemicals to keep it sitting in pipes. A whole-home system removes those harsh chemicals that cause dry skin, brittle hair, and bad-tasting drinking water. Furthermore, it protects your expensive appliances (like your Rinnai hot water system) from the internal corrosion and limescale buildup that town water often causes.

  • Absolutely. Our 0% upfront payment plan is available for all residential installations across Australia, regardless of your water source. Whether you are looking to treat harsh bore water, eliminate bacteria in tank water, or simply clean up town water, you can start today with $0 upfront and no interest, ever.
