Whole House Water Filter System – Premium Aragon Model
High-flow, three-stage filtration for cleaner water throughout your home.
The Premium Whole House Water Filter is designed to treat water as it enters the property, providing filtered water to your kitchen, bathrooms, showers, laundry and appliances.
Three full-size 20" × 4.5" Big Blue stages combine sediment filtration, high-capacity carbon filtration and a final European Aragon Plus cartridge. With flow rates of up to approximately 50 litres per minute, it is designed for normal household use without the restrictions of smaller drinking-water filters.

Why Choose the Premium System?
Unlike an under-sink filter that treats only drinking water, a whole-house system filters the incoming supply before it is distributed around the property.
This means water used for showering, bathing, washing clothes, cleaning and filling kitchen taps has already passed through the filtration system.
The Premium model uses three complementary stages rather than relying on one cartridge to do everything.
How the Three Stages Work
Stage 1 – Sediment Pre-Filter
Captures dirt, sand, rust and suspended particles, helping protect the more advanced carbon and Aragon cartridges.
Stage 2 – MATRIKX® CTO Plus Carbon Block
Uses coconut-shell activated carbon to reduce chlorine, chloramines, unpleasant tastes and odours, PFAS, VOCs and other organic chemical contaminants.
Stage 3 – European Aragon Plus
Combines mechanical filtration, adsorption and ion-exchange technology within a solid-block polymer containing silver and ion-exchange media.
Testing covers reduction of selected heavy metals, chlorine, chloramines, pesticides and other contaminants. The cartridge has a stated capacity of up to approximately 60,000 litres under appropriate conditions.

Filter Life & Maintenance
Replacement frequency depends on household water use, incoming water quality and sediment levels. As a general guide, an annual cartridge change is a sensible starting point for many households.
The sediment cartridge should be checked periodically, particularly after installation, as it provides a useful indication of what is entering the property.
The Aragon Plus cartridge has a stated capacity of up to approximately 60,000 litres, although actual service life varies with water quality and operating conditions.
We recommend replacing cartridges at sensible intervals rather than pushing them to their maximum capacity.

Installation and maintenance information
Installation & Weather Protection
The system is installed on the main cold-water supply and should be fitted by a suitably qualified plumber.
For sheltered installations, the standard mounting bracket may be sufficient. For exposed outdoor installations, we recommend the stainless-steel frame and protective cover to help shield the housings from sun and weather.
Mains Water & Rainwater
For chlorinated mains water, the Premium system provides broad whole-house filtration for sediment, chlorine, chloramines, PFAS and other contaminants addressed by the installed cartridges.
Rainwater and untreated supplies require additional consideration. Where microbiological contamination is a concern, additional treatment such as UV may be recommended.
Please contact us before purchasing for tank, bore, river or other untreated water sources.
What About Drinking Water?
Whole-house filtration significantly improves the water entering the property, but we still recommend a dedicated drinking-water filter at the kitchen tap as a final safeguard.
We commonly pair this system with a single-stage Doulton under-sink filter for an additional point-of-use filtration stage.
Standard vs Premium
Standard: sediment → carbon block → carbon block
Premium: sediment → carbon block → Aragon Plus
The Standard model is ideal for sediment, chlorine, taste, odour and general chemical reduction. The Premium model adds the Aragon Plus final stage for broader filtration.
