Description
Doulton DUO Benchtop Water Filter System Biotect Ultra Edition
If you are looking for the best water filter for a rental property or need a portable water purifier for travelling around New Zealand and Australia, this system is your perfect match.
Most people do not realise that if you do not use a water filter, your body becomes the filter. Your liver and kidneys have to work overtime to strain out the impurities found in everyday tap water. Investing in a high-quality water filter is one of the simplest ways to support your body’s natural detoxification, boost your mental clarity, and stay properly hydrated—which even supports healthy weight loss.
With the Doulton DUO, you can be completely confident that what is promised on the label is exactly what you get in your glass. Unlike unverified brands, Doulton products are backed by rigorous, independent testing data. It is a premium investment in your health that actually saves you money, costing only a few cents per litre compared to expensive, environmentally damaging bottled water.
Why This Product is the Ultimate Choice for Clean Water
Proven Contaminant Removal: This system actively removes microplastics, heavy metals like lead, chlorine, common pesticides, and harmful bacteria such as E. coli and Giardia.
Ideal for Renters & Travellers: Requires absolutely no permanent plumbing or alterations. You can easily attach it to your tap and disconnect it in seconds when it is time to move.
Worldwide Trust & Certification: Fully certified by global water safety authorities including NSF (standards 42, 53, and 401) and WRAS.
Eco-Friendly & Wallet-Friendly: Eliminate the need for single-use plastic bottles. Enjoy crisp, great-tasting water right from your kitchen counter for a fraction of the cost.
Zero Electricity Needed: Works entirely via your home’s water pressure, ensuring you have clean drinking water even during power outages.
Dual-Stage Filtration Tailored to Your Preferences
The Doulton DUO Benchtop filter features a robust, space-saving design that fits neatly next to your sink. It uses a smart, two-stage process to clean your water:
Stage 1 (Your Choice of Pre-Filter): Customise your system to target specific local water issues. Choose a pre-filter designed to boost the removal of fluoride or nitrates.
Stage 2 (Biotect Ultra Ceramic Filter): Water flows through a high-performance ceramic and proprietary carbon block cartridge. This stage targets microscopic bacteria, heavy metals, and chemical residues while keeping beneficial natural minerals intact.
