The system requires 1 of these cartridges to be replaced every 12 months or 7,000 litres, whichever comes first.
1st Stage of Filtration: Polyspun Pre-Filter Cartridge
Protect your system from the heavy sediment found in rain and ground sources. Our commercial-grade 1-Micron Polyspun Pre-Filter physically traps mud, rust, and algae. It is a critical component of a reliable water filter for bore water, ensuring crystal-clear flow and extending the life of your advanced Aragon cartridge.
2nd Stage of Filtration: Aragon Bio Filter Cartridge
Standard filters miss dangerous viruses and radioactive elements. The Aragon Bio is certified to eliminate these hidden threats. Tested by Independent Scientific Certification Bodies like the Institut Pasteur, it neutralises Rotavirus, Hepatitis A, and Uranium. It is the advanced heart of your rainwater and bore water filter, providing protection far beyond standard carbon blocks.
Hard water softening and scale protection
We understand the frustration of dealing with high mineral content in your bore water. That stubborn limescale that crusts over your kettles, taps, and showerheads isn’t just unsightly—it restricts flow and shortens the lifespan of your expensive appliances. These hard, damaging deposits are caused by the accumulation of sticky ‘Calcspar’ crystals.
The Aragon Bio offers a revolutionary solution with its advanced Quasi-Softening effect. Instead of removing beneficial minerals like a traditional softener, it fundamentally changes their physical structure. By transforming jagged, sticky Calcspar into soft, non-stick Aragonite, the filter ensures these minerals flow harmlessly through your water rather than clinging to surfaces. This naturally prevents scale build-up!
