Product Description

The Eco Hero 4 Stage Reverse Osmosis - Under Sink system is perfect for those who want to enjoy great quality purified drinking water conveniently at the turn of a tap. This system is neatly plumbed under your sink and is complimented by a Premium 3 Way Mixer Tap for a quality and aesthetic addition to your kitchen.

Of all methods to purify water, the process of reverse osmosis is one of the most advanced and effective. More than standard water filtration, the intense water purification process of reverse osmosis removes almost all contaminants found in drinking water, including total dissolved solids (TDS).

Better for the environment (and your home’s water usage), this system is fitted with the Pure Water Systems Eco-Hero-50 membrane. The Eco-Hero-50 is the latest in membrane technology, providing up to 300% improved wastewater efficiency when compared to rival membranes.

Unlike standard carbon water filtration, the ultra-fine 0.0001-micron Eco-Hero-50 membrane removes a minimum of 90.8% of total dissolved solids (TDS) from water. This reverse osmosis system significantly reduces organic and inorganic compounds such as fluoride, viruses, bacteria, herbicides, pesticides, nitrates, algae, phosphates and more. The end result is great tasting, healthier and purified drinking water, conveniently at the turn of a tap.

While reverse osmosis is excellent for removing contaminants (such as heavy metals like cadmium, arsenic and chromium), healthy minerals and salts can also be removed leaving your water acidic. For great potential health benefits (such as improved gut and kidney health), you can raise your water’s pH balance to a level considered alkaline by adding healthy minerals back to your water with a Remineraliser Cartridge

Optional final stage:
The Pure Water Systems pH Neutraliser Cartridge is an optional final stage of filtration; it refreshes the water in the holding tank, raising the water to a consistent pH level of approximately 7.5. Whilst reverse osmosis systems offer the highest level of water purification, many minerals can be removed in the process, which can leave the water mildly acidic. The calcite in this cartridge raises the pH to a level considered neutral, whilst the granular activated carbon effectively removes any remaining unpleasant taste and odour.

Reverse osmosis water is more than just healthier, great tasting drinking water. You can use reverse osmosis water for washing fruit and vegetables, cooking with, tea and coffee, pets’ water dishes, watering plants and more!

The under sink Eco Hero 4 Stage Reverse Osmosis system is Watermark certified and has NSF 42 certified components. This system comes ready to install, complete with cartridges and high-quality housing parts and fittings.

The Pure Water Systems purification system incorporates a precision machined, full metal construction pressure limiting valve and dual check valve, providing protection from pressure spikes, preventing backflow, and resisting water hammer. Whilst this is a requirement under Australian Standards, we have chosen this valve as it is ultra-reliable and performs to the highest standard, giving you peace of mind that your system is protected. 

Easy to maintain and economical

Generally, our reverse osmosis systems only require cartridge replacement every 12 months, costing roughly only 3-5 cents per litre.

When you shop with Pure Water Systems you'll have peace of mind
