How it Purifies your water

Step 1: Pre-Filtration
First, sediment + activated carbon (1000 iodine value) filtration to reduce chemical and particulate contaminants. This stage protects the RO membrane.

Step 2: Reverse Osmosis Purification
The RO membrane removes a wide range of unwanted contaminants with a 0.0001 micron membrane, including but not limited to fluoride, nitrates, heavy metals, bacteria, viruses, cysts, pharmaceuticules & more

Step 3: Mineral Enhancement
Finally, a mineral + activated carbon stage adds back essential minerals for a healthier, cleaner, smoother taste, so the water doesn’t feel flat or stripped.

Smart Monitoring (No Guesswork)
The built-in display tracks water quality and filter life in real time, so you always know your system is performing.

Rock-Activation Remineralisation

Created by the most advanced Geo-lab in the world. Some of the highest quality water sources have been studied for prusiung healthy drinking water.

RO & Contamination Removal

Reverse Osmosis (RO) is one of the most trusted water purification technologies in the world - used in medical facilities, laboratories, pharmaceutical production, bottled water manufacturing, and even desalination plants. By forcing water through a semi-permeable membrane as fine as 0.0001 microns, RO removes dissolved contaminants including fluoride, nitrates, heavy metals, bacteria (E.coli), viruses & protozoan parasites such as Giardia, PFAS, micro & nano plastics, pharmaceuticals, cysts and excess total dissolved solids.

Our system is paired with 2 additional highly active carbon stages, these aid the process and help protect the membrane delivering exceptionally purified drinking water.

Reverse Osmosis Mineral+ | Fluoride, Nitrate removal filter

Very good system. We have had another RO system in the past and the flow was slow. This system is great, no power or tank is good and the water quality is very good. Highly recomend. Nice team to deal with too. Cheers

Reverse Osmosis Mineral+ | Fluoride - Nitrate Removal

Does what it says. Much better than tap water and other filters. We are all much better drinking this. I wish the flow rate was faster but its a small price to pay. I would give it 5 stars if the flow rate was higher.

Reverse Osmosis Mineral+ | Fluoride - Nitrate Removal

High Nitrates? or looking to remove Fluoride?

The RO Mineral + is highly effective at removing Nitrates and Fluoride. Unfortunately, New Zealand has a growing issue with elevated nitrate levels and we believe everybody should prioritise clean, accurately filtered water for effective, safe hydration.

Remineralization

An inherent drawback of RO filtration is the removal of essential minerals. While effective at eliminating contaminants, this process produces demineralized, acidic water with reduced bioavailability and hydration potential. The RO Mineral+ addresses this issue through a specialized post-filtration stage containing 100% natural minerals. This stage reintroduces beneficial minerals and elevates the pH to Alkaline, resulting in balanced, mineral-enriched water that supports optimal hydration.

FAQ's

Does reverse osmosis remove minerals from water?

Yes. Reverse osmosis removes up to 99% of dissolved solids, including both harmful contaminants and beneficial minerals such as calcium and magnesium. That’s why a quality remineralisation stage is important for long-term drinking water quality.

Is RO water safe to drink long-term without remineralisation?

While RO water is extremely pure, long-term consumption of de-mineralised water is not ideal. Adding minerals back helps support:

  • Proper hydration
  • Electrolyte balance
  • Natural taste

The RO Mineral + accurately restores key minerals after filtration. Increases pH to Alkaline.

How often does the RO Mineral + cartridges need replacing?

Stage 1 and 3 are around 12months and stage 2 (RO membrane) around 24months. This does depend on daily use, the system had a digital flow meter to monitor filter life.

Can children and pregnant women drink remineralised RO water?

Yes. Remineralised RO water is safe for the whole family, including children and pregnant women, as it provides essential minerals while removing harmful contaminants.

Does this system require any power?

Yes but it does not require a constant power supply. The system has an internal battery that charges via USB C and each charge lasts around 8 months. This function monitors the water quality, filter life and auto-flushing for the RO filter.

Is this system good for NZ water?

Yes, very good. It removes all common contaminants found in NZ water supply. We continue to routinely lab test (Hill Labs) actual NZ tap water to support and ensure our systems do what they say.

Can you help with install?

Yes, we offer a fixed-rate install service for this system. Just $200 and a professional will arrive and install. Available throughout most of NZ.

I live in a rental, can I take the filter system with me?

We hear this often. Yes, the systems are easy to remove and take with you. We have also added a dual tap option available which means the filtered water comes through the same tap as the kitchen sink.
