Why Certification Matters in Water Filtration

When it comes to water filtration, not all systems are created equal. Many products make bold claims about what they remove from your water—but only a few have the independent certifications to back those claims up.

The Puretec FilterWall F6 is NSF/ANSI certified, meaning it has been tested and approved by one of the most trusted global organizations in water quality. These certifications verify the system’s ability to remove or reduce:

Chlorine and chloramine
Heavy metals like lead and mercury
Volatile organic compounds (VOCs)
Pesticides, herbicides, and pharmaceuticals
Microplastics and sediment

Why is this important? Because you’re relying on these systems to protect your family’s health. If a system isn’t certified, you’re essentially trusting marketing without proof. Certification ensures what’s promised is actually delivered.

Buying an uncertified system is like buying a seatbelt that hasn’t been crash tested—why take the risk?

Puretec F6 – Best Value Water Filtration System for Australian Homes

The Puretec FilterWall F6 is a market leader for good reason. It’s the only system in this comparison that carries NSF/ANSI certification, and it's designed with long-term durability and servicing simplicity in mind.

Key Benefits:

Independently certified filtration performance
Long-lasting 20" standard cartridges
DIY-friendly servicing ($540/year)
Powder-coated aluminium housing – built for Australian UV conditions
10-year warranty

It’s the best choice for families wanting maximum protection, low running costs, and flexible filter options from other brands.

Water Analytics – Aesthetic Design, High Long-Term Cost

The Water Analytics Full Home Water Refining System features a stylish design and offers a subscription servicing model. However, the system uses proprietary filters that are not available from third-party suppliers, meaning you're locked into their replacement program indefinitely.

Downsides to consider:

No NSF/ANSI certification
3-year warranty – the shortest on this list
$560/year servicing, and $4,500 replacement cost every 3 years if outside warranty

Over a decade, this adds up to one of the most expensive systems in the market.

Complete Home Filtration – Mid-Range System, Limited Flexibility

Complete Home offers a slightly longer 5-year warranty but uses non-standard 15" proprietary filters, which means you're again locked into their OEM cartridges. With a 1.3x/year service frequency, costs rise quickly, especially with a system that lacks independent certification.

What to know:

No compatibility with 10" or 20" cartridges
Higher average annual running cost (~$747/year)
Lacks third-party performance verification
Plastic housing may deteriorate under sun exposure

Great Water Filters – Budget Option with Higher Servicing Frequency

If you're on a tighter budget, Great Water Filters might be appealing upfront. It uses standard 10" cartridges, which are easier to source. However, they need to be replaced twice per year due to smaller capacity, leading to a higher long-term spend.

Notable points:

Lower install cost ($4,000)
$790/year in servicing (2x $395)
5-year warranty
No NSF/ANSI or independent verification

While it’s a step above tap filters or under-sink units, long-term costs rival premium options—without the certification or housing durability.

System Appearance & Housing Colour Options

When installing a whole house water filtration system, aesthetics matter—especially for homes where the unit is visible outdoors.

Puretec F6 is available in a sleek, neutral powder-coated finish that blends in seamlessly with most Australian exteriors. It’s UV-resistant, making it ideal for sunny climates.
Water Analytics and Complete Home Filtration use plastic housings, typically white or off-white. These can yellow, crack, or degrade over time if exposed to the sun.
Great Water Filters also uses standard plastic housing with limited finish options and lower resistance to outdoor conditions.

Choosing a system with a colour finish designed to blend into your home's exterior can be the difference between a professional-looking install and an eyesore.

Conclusion: Which Whole House Water Filter is Best in Australia?

If you're looking for the best combination of certified filtration, long-term value, and system durability, the Puretec F6 is the clear winner.

Best 10-year value at $10,400 total
Only system with independent certification (NSF/ANSI)
Flexible filter replacements with 20" standard compatibility
Superior build quality and outdoor-ready appearance

The Water Analytics, Complete Home, and Great Water Filters systems all come with compromises—whether it’s locked-in filter costs, lack of certification, or high servicing requirements.

For homeowners serious about water quality and protecting plumbing, appliances, and health, the Puretec F6 delivers on performance, reliability, and flexibility.
