Doulton Underbench Water Filter System with Biotect Ultra Cartridge
Looking for the best under-sink water filter to remove microplastics and heavy metals in Australia and New Zealand?
If you are searching for an honest, high-performance water filtration system that actually delivers on its promises, the Doulton Underbench Water Filter System (Biotect Ultra Model) is the gold standard for your home.
Many people don’t realise that if you don’t use a high-quality water filter, your body becomes the filter. Your liver and kidneys have to work overtime to process the invisible contaminants running straight through your kitchen tap. This premium underbench system acts as your home’s first line of defense, serving clean, great-tasting water that supports your body’s natural detoxification, improves mental clarity, and makes staying hydrated effortless.
Why Doulton is the Trusted Choice for Clean Water
Unlike generic water filters that make broad, unverified claims, Doulton products are backed by rigorous, independent testing data. As the official Doulton distributor in New Zealand, we provide a proven solution trusted worldwide to safeguard your household’s drinking water.
Real Health & Financial Benefits
Invest in Your Longevity: Clean, contaminant-free water helps digestion, enhances focus, and supports your overall wellness goals, including weight management.
Ditch the Plastic Waste: Protect beautiful Australian and New Zealand coastlines by eliminating single-use bottled water.
Unbeatable Value: Stop overpaying for bottled water. This system delivers crisp, pure water for only a few cents per litre.
High-Performance Contaminant Removal
The heart of this system is the Doulton Biotect Ultra Cartridge (2501). Made from a durable ceramic outer shell combined with a proprietary carbon-based core, it removes harsh chemicals and microscopic hazards while keeping healthy minerals intact.
Microplastics & Sediment: Filters out microscopic plastic fibers and rust.
Heavy Metals: Targets dangerous heavy metals like lead.
Disinfectants & Chemicals: Removes chlorine and harsh pesticides.
Microorganisms: Eliminates common bacteria (such as E. coli) and giardia cysts.

Product Specifications
Designed to fit discreetly under your kitchen bench, this compact unit connects directly to your cold water line without cluttering your countertops.
Housing Material: Robust, compact, food-grade plastic structure.
Connections: 3/8″ push-fit inlet and outlet (ideal for standard 3/8″ flexible plastic piping).
Flow Rate: Achieves up to 3.3 Litres per minute (1.9 L/m is optimal for maximum filtration).
Operating Limits: Working pressure of 10 to 125 psi; temperature range of 5°C to 30°C; pH range of 5.5 to 9.5.
Dimensions: 30 cm Width × 60 cm Height × 30 cm Depth.
Cartridge Lifespan: 10″ tall cartridge with an M12 thread size, providing 6 months of clean water before a simple replacement is needed.
Easy Installation & Use Cases
Whether you are upgrading your home kitchen, setting up a holiday bach, or optimising your office breakroom, this mains water filter is highly versatile.
Thanks to the secure push-fit connections, installation is straightforward and can be completed without a professional plumber, depending on your DIY confidence. You can pair this unit with a dedicated single-spout pillar tap, or integrate it directly into a 3-way mixer tap that handles hot, cold, and filtered water from one stylish unit.
Pro Tip for Optimal Flow: We strongly recommend using an official Doulton tap. While many third-party taps use a narrow 1/4” pipe that restricts your water flow, Doulton taps feature a full 3/8” connection specifically engineered to maintain perfect, steady water pressure.
