If your home is connected to town water, you may wonder whether a whole-house water filter is really worthwhile. After all, Australian municipal water is treated and monitored. It should already be safe to drink.
That is generally true. Town water is disinfected to control harmful microorganisms, so most homes do not need ultraviolet sterilisation or an elaborate rainwater-treatment system. But “safe to drink” does not always mean pleasant to drink, shower in or cook with.
Chlorine or chloramine may create an unpleasant taste and smell. Sediment can arrive through ageing mains and local pipework. Depending on your location and priorities, you may also want to reduce PFAS, fluoride, pesticides, volatile organic compounds or disinfection by-products.
A correctly chosen whole-house system treats the water where it enters your property. That means filtered water reaches the kitchen, bathrooms, laundry and shower—not just one little tap beside the sink.
So, which brands are genuinely worth considering?
What makes a whole-house filter worth buying?
Before looking at brand names, look at what is inside the housings.
For ordinary town water, a good starting combination is sediment filtration followed by quality activated carbon. The sediment cartridge catches rust, dirt and suspended particles. The carbon stage reduces chlorine, unpleasant tastes, odours and various organic chemicals.
If your council uses chloramine rather than chlorine, ordinary granular carbon may not be the best choice. Catalytic carbon generally provides better chloramine reduction. If fluoride or PFAS is a priority, check that the system includes media specifically designed and tested for those contaminants.
Also check the flow rate. A small cartridge may work beautifully at a drinking tap but seriously restrict a house when two showers and the washing machine operate together. Ask about replacement frequency, cartridge prices, published performance data, pressure ratings, warranty support and parts availability.
Finally, budget for installation by a licensed plumber. A cheap system becomes remarkably expensive if it restricts flow, leaks or cannot be serviced in two years.
Puretec: polished and widely available
Puretec is one of Australia’s best-known filtration brands. It offers everything from conventional cartridge housings to its attractive FilterWall systems. Depending on the model, Puretec targets sediment, chlorine, PFAS and the effects of hardness.
The FilterWall range offers 30 or 55-litre-per-minute models and a stated 10-year “peace of mind” period. It is a polished solution for homeowners who want a covered system that looks tidy beside a modern house.
The downside is price. Current FilterWall models can cost several thousand dollars before any installation considerations. Puretec is certainly credible, but buyers should compare the filtration media, replacement costs and required flow rather than assuming a handsome enclosure makes the water cleaner.
Complete Home Filtration: a turnkey service
Complete Home Filtration takes a service-based approach. The company offers an in-home water assessment, system design, professional installation and ongoing assistance. Its systems can be tailored to local water and household requirements.
This can be valuable if you want someone to manage the entire project. Australian water differs between regions, and the disinfectant used may be chlorine or chloramine. A tailored recommendation can prevent you buying filtration stages you do not need.
The trade-off is that pricing and exact configurations may require an assessment and quotation. Ask for the proposed cartridge specifications, independent performance information, annual servicing cost and projected replacement schedule in writing before committing.
Filter Systems Australia: flexible and price-conscious
Filter Systems Australia offers modular single, twin and triple systems, including WaterMark-certified 20-inch by 4.5-inch housings. This approach can provide good value for someone who understands which cartridges are required.
The advantage is flexibility. You can select sediment, carbon and speciality cartridges to suit the water. Replacement cartridges in common sizes are also easier to compare.
However, the buyer must pay attention. Two systems with three blue housings can perform very differently depending on the cartridges inside. Do not buy solely by the number of stages. Confirm the contaminant-reduction data and flow rate for the exact cartridge package supplied.
Why I favour AlkaWay for Australian town water systems.
AlkaWay offers several whole-house configurations rather than pretending one filter suits every water source.
For a medium-to-large home on town water, the AlkaWay Optimal Whole House System is a strong all-round choice. It is WaterMark certified and combines a one-micron sediment filter, a PFAS carbon block and an Ultra-D sub-micron filter.
Together, these stages target sediment, chlorine, chloramine, PFAS, VOCs, heavy metals and pathogens. The cartridges are normally replaced every 12 months, although actual life depends on water quality and usage.
For households that specifically want whole-house fluoride reduction, my preference is the AlkaWay Absolute Whole House System. This three-stage system combines fine sediment filtration, a coconut-shell carbon block for chlorine, chloramine, PFAS, VOCs and other chemicals, and an activated-alumina stage for fluoride and arsenic.
Published performance figures include greater than 90% chlorine reduction, greater than 83% chloramine reduction, greater than 98% PFAS reduction under the stated test conditions, and up to 90% fluoride reduction. Actual performance and cartridge life naturally depend on incoming water quality, flow and household consumption.
The Absolute requires no salt, electricity or backwashing. It is designed for homes with up to three bathrooms, and its cartridges are expected to last approximately 12 to 24 months, depending on use and water conditions.
AlkaWay also offers the Natural Whole House System, which uses fine and sub-micron filtration to address bacteria, cysts and other contaminants.
That model is particularly relevant to rainwater or supplies with microbial concerns. For normal disinfected town water, however, Optimal or Absolute will usually be the more logical starting point.
The value of support after installation
The hardware matters, but so does the company behind it. AlkaWay has worked with water filtration, alkaline water and molecular hydrogen for more than 26 years.
That experience helps us recommend a system based on your water source and concerns rather than automatically selling the most expensive option. It also means customers can obtain replacement cartridges, installation guidance and practical assistance from people who understand the products.
Whole-house filtration is not a fit-and-forget purchase. Cartridges must be replaced, housings maintained and unusual water conditions investigated. Long-term support is part of the system’s real value.
My conclusion

Puretec is worth considering if you want a premium-looking, widely distributed system. Complete Home Filtration suits buyers wanting an assessment and managed installation. Filter Systems Australia offers flexible modular systems for price-conscious shoppers prepared to study cartridge specifications.
For the strongest combination of targeted filtration, published performance, sensible system choices and experienced Australian support, I believe AlkaWay offers the better overall value.
Choose Optimal when you want broad reduction of sediment, chlorine, chloramine, PFAS and heavy metals. Choose Absolute when whole-house fluoride reduction is also a priority. If you are uncertain, ask AlkaWay to help match the filtration media to your local town water before you buy.
The best whole-house filter is not necessarily the one with the most stages, the biggest cabinet or the most alarming advertising.
