Transform your tap water into refreshing, purified drinking water |for just a few cents a day

Tap water often harbors an array of impurities and contaminants. Reverse Osmosis Water Filters target the widest range of water impurities imaginable, including harmful substances like PFAS, fluoride and chlorine. Reverse osmosis is uniquely capable of reducing contaminants ranging from bacteria and viruses to agricultural runoff like pesticides and fertilisers to dissolved metals such as lead, arsenic, and iron. Research demonstrates that reverse osmosis technology excels at eliminating trace contaminants, including perfluorocarbons and trace pharmaceutical residues. Enjoy clean, contaminant-free water in your home with our Ultra High Purity Reverse Osmosis System, and have the peace of mind that comes with knowing your water is free from fluoride, chloride, and a wide array of other impurities.

The Advanced Filter Technology - 3 Stages of Filtration

Omnipure Q-Series-Q5640 GAC-Filter

Omnipure Sediment Pre Filter Block WL5540 (Stage 1 & 3)

Made from 100% pure Coconut Granular Activated Carbon (GAC) and rigorously tested, it effectively reduces PFAS, Chlorine, Chemicals, Pesticides, Heavy Metals, Taste & Odour. We recommend replacing every 12 months or 7,500L depending on water quality. Made in USA.Pes

How does the Reverse Osmosis Membrane Work?

A reverse osmosis membrane is a thin film with tiny pores that permit only water molecules to pass through, blocking all contaminants. It’s made of a semi-permeable material that allows water flow but blocks dissolved salts, organics, bacteria, and pyrogens. When pressurised, pure water diffuses through the membrane into the permeate flow, leaving contaminants behind. Reverse osmosis removes up to 99% of impurities.
Polluted water is forced through the semi-permeable membrane by mains pressure. Pure water passes easily, while pollutants larger than.0005 microns are washed away into a waste stream that goes down the drain. This waste stream contains all of the filtered-out contaminants, including pesticides, metals, bacteria, and viruses. 

Restore Nutrients to Purified Water with Remineralisation

Reverse osmosis effectively removes harmful contaminants like PFAS, cadmium, arsenic, and chromium. However, it also filters out beneficial minerals and salts, resulting in acidic water. For improved health outcomes, raise your water’s pH to an alkaline level by adding healthy minerals back into it. Our Remineraliser Cartridge is included in these systems and infuses your water with essential minerals and salts to restore balance and alkalinity:

Certification

You can trust this reverse osmosis system to deliver safe, clean water. It meets the stringent WaterMark AS/NZS 3497 standards for structural durability under pressure, certified under number 52014. WaterMark also mandates that all components, including the filter cartridges, comply with NSF/ANSI 42 standards or higher for water filtration safety. 
These systems are hand-assembled right here in Australia and wet-tested to guarantee superior quality. Our Watermark certification indicates full compliance with Australian plumbing codes, so you can have total peace of mind knowing your RO system adheres to local regulations.

Important Considerations for Rainwater Filtration

This product is designed specifically for use with municipal water supply systems or well water with adequate pressure. It is not recommended for rainwater filtration due to the waste water component inherent in reverse osmosis systems. 
Reverse osmosis water filters require a consistent water pressure of at least 40 psi, which is typically provided by municipal water mains or a dedicated pressure pump. Rainwater collection systems often lack the necessary pressure for the efficient operation of reverse osmosis filters.
For optimal performance and to avoid potential issues, we strongly advise against using this product for rainwater filtration. It is specifically engineered to work seamlessly with traditional water supply sources that meet the required pressure specifications.

 

Hassle-Free Installation

Installation of your reverse osmosis system is straightforward with the included guide and complete package of parts. All necessary fittings, tubing, and adapters are provided for a seamless setup. 

For step-by-step guidance, refer to the installation manual you will receive with the kit. Additionally, check out our blog post here for tips. With the materials included and these resources, you’ll be able to get your new system up and running smoothly. 

We want to ensure your installation experience is easy and stress-free. Please reach out to our support team with any questions!

Everything in its Place: Hose Colour Guide

Our reverse osmosis systems come equipped with colour-coded hoses for intuitive installation.

– Black hose for waste water drainage  
– White hose connects to the storage tank
– Red hose for feed water inlet to the system
– Blue hose for filtered water flow to dispensing tap after passing the remineraliser

With each hose distinctly coloured, you’ll know exactly where everything connects once you unpack your system. No guesswork is required!
The colour-coding allows for quick identification of the purpose and flow path of each flexible hose. 
With the right hoses in the right places, you’ll be enjoying purified water in no time. Our systems come with everything needed for  efficient filtration and refreshing hydration.
