Australian Design and Local Water Conditions

Complete Home Filtration

Complete Home Filtration is Australian founded and operated, with the whole home systems designed around Australian conditions. The CHF-6000 can be adjusted according to the property’s water supply, plumbing and household needs, with different cartridge and treatment media for different water needs.1, 2

ShieldWater

ShieldWater supplies whole home filtration systems for different water sources and conditions, including mains water, tank water and hard water. Its range includes systems marketed for hard water prone areas, like Western and South Australia.3, 4

Whole Home Coverage

Complete Home Filtration

The CHF-6000 treats water at the point where it enters the property, so filtered water can be supplied throughout the home. Depending on the configuration, treatment can include sediment, chlorine, chloramine, heavy metals, hardness and scale, with published flow rates varying between 32 and 50 L/min.2

ShieldWater

ShieldWater has several whole home configurations using different cartridge combinations for treatment requirements including sediment, chlorine, chloramine, PFAS and scale. Its larger 20-inch systems have published flow rates of up to 75 L/min, depending on the configuration. Shield Water doesn’t publish their independent laboratory performance results.5, 6

Installation and Who Does It

Complete Home Filtration

Once the appropriate CHF-6000 configuration has been determined, installation is performed by a licensed plumber on the property's mains water supply. 

The system is positioned between the water meter and the first inlet tee-off into the home, with the installation requirements considered as part of setting up the system.2, 7

ShieldWater

ShieldWater supplies the filtration equipment, but the customer will need to arrange installation themselves. A licensed plumber is required to connect the system to the property's mains water supply.5

Cartridge Cycle and Ongoing Cost

Complete Home Filtration

CHF-6000 cartridges typically need replacing every 6 to 12 months. The interval will depend on the property's water quality, household water use and the cartridges installed.

Replacement costs depend on the configuration because different systems use different combinations of filtration and treatment cartridges.2, 8

ShieldWater

ShieldWater's cartridge replacement intervals vary by the cartridge type and operating conditions. Some cartridges have a published service life of up to 12 months, although heavier sediment loads and higher water use may mean they need replacing sooner.9

Softening and Hardness Handling

Complete Home Filtration

For homes with hard water, the CHF-6000 can be configured with cation-exchange resin to reduce calcium and magnesium, the minerals responsible for water hardness. Where the priority is limiting limescale rather than removing hardness minerals, scale-prevention media is another option.2, 10

ShieldWater

ShieldWater offers cartridges designed to limit limescale buildup. These provide scale control rather than conventional ion-exchange softening, so they do not remove calcium and magnesium from the water in the same way as a traditional water softener.4, 9

Local Service and Aftercare

Complete Home Filtration

Complete Home Filtration provides installation and services across WA, QLD, VIC, NSW, ACT and SA. Customers are also able to access filter replacement reminders, maintenance guidance and technician support.

The CHF-6000 comes with a 2-year manufacturer's warranty. Plumbing workmanship is covered for up to 7 years, depending on state requirements.2, 11, 12

ShieldWater

ShieldWater sells replacement cartridges for its whole home systems, so customers can purchase the appropriate replacements when their existing cartridges need changing. The replacement interval depends on the cartridge, water quality and household use.9

Certification and Scope

Complete Home Filtration

Complete Home Filtration publishes several certifications and manufacturing credentials across its products. These include WaterMark certification, testing against relevant NSF standards and ISO 9000-accredited manufacturing requirements. 

For the CHF-6000, the documentation identifies the WaterMark licence as WMK023341 and also provides information about NSF testing and assessment through IAPMO, along with its manufacturing requirements on its certifications page.2, 13

AquaStream

ShieldWater publishes WaterMark certification for its SHIELD water filtration system under licence WMK030064. Its product documentation also references AS/NZS 3497 for applicable systems.

Any certification and compliance claims regarding your filtration system should be checked against the specific process or product covered by the documentation, rather than assumed to apply to every product in the range.5, 14
