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.
This is what 6 months of unfiltered water looks like
Sediment, minerals, disinfectants and microplastics build up over time.What you can't see can affect taste, odour and your long-term plumbing.

Frequently asked questions
- How does a whole-home water filtration system work?
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.
- How much does a whole-home filtration system cost?
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.
- What are the ongoing payments after the 90-day no-payment period?
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.
- What warranty comes with my system?
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.
- How long do the filters last and what is the maintenance?
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.
- Is whole-home filtration really worth it for town water?
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.
- Can I get the 0% payment plan if I’m on tank or bore water?
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.
