Reverse Osmosis Water Filter (Nitrate Removal) | Under Bench | The Canterbury

The Canterbury is suitable for small, medium and large households, providing a "Benchtop" solution for clean drinking water for you and your family. The compact under-sink design fits neatly inside most kitchen cupboards. With simple connections and a practical layout, installation is straightforward for a plumber, handyman, or confident DIY installer.

Reverse Osmosis is internationally recognized as being the most effective filtration system over the widest range of contaminants. This water filter unit removes Nitrates, Chlorine, Lead, Chromium, Barium, Cadmium, Viruses, and Pesticides from your tap water. Reverse Osmosis is the best technology to remove nitrates from your drinking water with 95% of nitrates eliminated. 

Instead of constantly buying bottled water or relying on basic jug filters, you can have filtered drinking water available on demand straight from your own dedicated tap. A reverse osmosis system can help you save money by reducing the need to buy bottled water. It is a smarter, more convenient way to enjoy filtered drinking water at home while cutting down on single-use plastic waste.

This four-stage filtration process consists of a Pre-filter Sediment Filter Carbon Filter, a Reverse Osmosis Membrane filter and a final Carbon filter to polish the water.   

Is Reverse Osmosis the best water filter?

Reverse Osmosis water purifiers are the optimum system for removal of contaminants from water as they filter down to an ionic level of 0.001 microns.  Not only are they very efficient at removing a wide range of chemicals, heavy metals, bad taste, and odour, but they will also remove some fluoride, bacteria and all the ‘dissolved solids’ from the water which normal water purifiers will not remove. 

Typically bore water can contain around 120 to over 1000 parts per million (PPM) of dissolved solids. After passing a standard carbon-based water purifier the Total Dissolved Solids (TDS) reading will not have changed.

After passing a reverse osmosis membrane the reading will drop around 95 to 98%. Consequentially the texture of the water has a slightly smoother, silky feel to it compared with non reverse osmosis water.

How do Reverse Osmosis filters work?

After passing at least one pre-filter to remove sediment the water passes through a Carbon filter then through a semi permeable membrane. The water pressure pushes the pure water through the membrane while the waste product is discharged to waste. The retentate stored into the water reservoir until ready to be used on demand. 

Because the reverse osmosis membrane is slow to produce pure water (between 3 to 6 litres per hour depending on available water pressure) the system is normally installed under the sink and is linked to a storage tank (usually 10 to 12 litres capacity), which holds the pure water until required.

This water is accessed by simply turning on your dispensing tap as the water is required, the system will automatically refill the storage tank as water is used.

Easy Installation, Low Maintenance

This system is designed to be installed neatly under your sink and connected to a dedicated filtered water tap. Once installed, it works quietly in the background and provides filtered water whenever you need it.

Filter changes are simple, and ongoing maintenance is minimal, making it a practical choice for busy households and workplaces.

Perfect for Everyday Use

Filtered reverse osmosis water is ideal for drinking, cooking, coffee machines, kettles, tea, baby formula, pets, aquariums, ice makers, caravans, motorhomes, offices, cafes, and food preparation.
