Ultra Filter Specifications

The Ultra Filter stands out as a unique filtration solution with its exceptional capacity to effectively remove challenging microorganisms and contaminants. 

When it comes to eliminating harmful bacteria, including Giardia, Cryptosporidium, E. coli, and more, the Ultra Filter's 0.01µ Micron filter media is specifically designed for this purpose. It ensures the removal of various waterborne microorganisms and contaminants commonly found in tank water systems, which may include concentrations of E. coli, bacteria, and others.

Furthermore, the Ultra Filter proves to be an excellent choice for addressing the issue of Microplastics and Nanoplastics. With its 0.01µm filter mesh media, it effectively filters out these particles. Given the growing awareness of micro and nano-plastics present in water sources, including town supply, tank or rainwater, the Ultra Filter's capability to remove them is crucial. Ongoing research explores the potential long-term health consequences associated with these contaminants.

Whether you rely on city tap water, tank water, bore water, aquifers, reservoirs, creeks, or springs, the Ultra Filter remains relevant and valuable for ensuring cleaner and safer water supplies.

Pre-filter recommended: approx. 5-20µ (micron) mesh size.
Filter Lifespan: 18 months, dependent on regular backflushing.
Working Pressure: 15 - 50 PSI (pressure reducing valve required for higher pressures).
Includes a backflush facility with a 3rd port for maintenance.

Alka Spring Specifications

The ALKA SPRING is a revolutionary antioxidant composite cartridge that ionizes and enhances tap water using Far-Infra-Red (FIR) Energy Beads and Mineral balls. This system raises tap water pH to 8.5-9.5, infuses it with negative ORP antioxidants, and restructures water molecules for better hydration and absorption. It also increases oxygen uptake and retains essential minerals, supporting daily health and vitality.

Distinctive features of the ALKA SPRING include its use of FIR beads, made from natural maifanshi stone and seabed minerals, to emit beneficial infrared energy, and its capacity to enrich water with up to 90 trace minerals like strontium and lithium for improved bodily functions.

The ALKA SPRING is particularly effective with different water sources. Rainwater, often acidic and mineral-deficient, benefits from remineralization, especially when stored in concrete tanks which naturally alkalinize the water. Conversely, Reverse Osmosis water, which is free of contaminants but also stripped of minerals, requires demineralization to enhance pH and antioxidant presence effectively.

Installation may require additional accessories like a FILTER ATTACHMENT KIT or a FILTER TAP, with several types available to meet user needs.

The cartridge also features Maifenite, or "Wisdom Stone", packed with a broad spectrum of minerals and trace elements, renowned in Asia for its health-promoting properties.


Capacity: 3000 liters, 10-15 months for a 2-3 person household.
Hygienic Life: Maximum 2 years.
Installation: After an existing filter and before the filter tap.
Working Pressure: 15 - 65 PSI (pressure reducing valve needed for >70 PSI).
Working Temperature: 5-40˚C.
Contains clay balls and Maifenite (Wisdom stone), packed with a wide range of minerals and trace elements.

Height: 35cm x Diameter: 7cm.

FluorEx Filter Specification

This incredible technology offers the most effective removal of fluoride, providing non-detectable levels right at the beginning of the filter's life. With a capacity of 2000 liters, this filter is designed to provide long-lasting performance.

What makes the FluorEX Max truly remarkable is its all-natural, alumina-free composition. Unlike many other cartridges on the market, it leaves healthy minerals like calcium and magnesium in the water, (not like Reverse Osmosis Systems) creating a more balanced and enjoyable drinking experience. And the best part? It doesn't waste any water, unlike reverse osmosis systems.

In independent tests conducted by Ionza, the FluorEX Max was proven to remove fluoride with exceptional efficiency. Samples taken from Auckland City showed fluoride content of less than 0.05g/m3, making it virtually undetectable. We have tested many cartridges. Most of them had in common that they claim to remove 'up to 99% fluoride' and as Hill Laboratories, Hamilton NZ proved with samples taken by us, they did not! Most of them just took out 40-50% of fluoride, one achieved 78% but the water tasted bitter. Most of those contain alumina as media which is fraud with issues about aluminium leaching into the water. Additionally, this remarkable filter also removes heavy metals and arsenic, ensuring that your water is clean and safe. 

With a removal rate of 99% at the beginning of cartridge usage and approximately 90-95% after 2000 liters (*depending on water source and prefilter setup), the FluorEX Max delivers consistent and reliable performance. It has a capacity of 2000 liters or approximately 6-12 months, depending on water usage.

We highly recommend our Active Pure filter is installed upstream of the FluorEx filter to to remove heavy metals, so it protects the capacity of the FluorEX Max filter to focus on fluoride predominantly.


Capacity: 2000 litres, or 6-12months. This means approx 12 months for 1-2 person household, or 6 months for 4 person household (*depending on volume of water used).

Monitoring of usage: We recommend to install a water flow meter to monitor usage.

Water Flow rate: The FluorEX-Max filter is most effective to run at approx 1.5 liter/min. The flow rate can be set up by the installer or by yourself: If your water flow is greater than 2 litres/min (if it takes you approx 5 seconds or less to fill your cup with filtered water) your water flow is travelling too quickly.

Installation: If this is the first time installing this you will require a Slimline housing 10" - Please add this to your cart if you don't already have one 

  • Capacity: 2000 litres
  • Flow Rate: 1.5liters/min
  • Removal rate of 99% at the beginning of cartridge usage and approximately 90-95% after 2000 liters (*depending on water source and prefilter setup)

Test result Fluoride sample 1 = FluorEX-Max filter:.


The tap water in Auckland City contains approximately 0.78g/m3 of fluoride content. However, after undergoing the FluorEX Max filtration process, the fluoride content in the water was significantly reduced to less than 0.05g/m3. This reduction in fluoride content resulted in the water being classified as non-detectable for fluoride

Does this filter remove arsenic?

Yes, it can remove both forms of Arsenic (III & V), this data is from our internal research. Chemically speaking, Fluoride is even more difficult to remove than Arsenic and our system removed virtually all of it in independent testing.

Been a supporter and networker for Ionza Products for quite sometime.

absolutely love the taste

We have purchased the filtration system that is installed under our sink and gets rid of all the nasties in Auckland Tap water, including fluoride and adds in Alkaline, absolutely love the taste.

Alix B
We love the taste and softness

Thank you for our wonderful Alka city total filter system! We love the taste and softness of our water now and never travel without filling up a bottle from home to take for the day.

One thing that we also really love is that Miriam is keeping an eye on when filters need changing and sending these on to us (Auto-Shipment), which means that our water is always fresh and pure - this makes life much simpler.

gained huge relief

Product arrived promptly
Unit came with fittings which made it a breeze to install in my existing under-sink filtration system. Best part of the circuit is to cut the hose between the system's outlet and the bench-top tap, and insert the cartridge there.

The water has fine bubbles - hydrogen so I'm told - which are good for you. The pH tests to over 9, full-time on tap 24 hours a day.

My wife and I have had unexpected health benefits already - my wife has gained huge relief from deep chronic bone-aches which were giving her agony every morning, and I have had a marked reduction in night-time snoring. It's possible that the alkaline water has been reducing inflammation levels in the body for both of us.

Normally, if you want healing waters, you have to move to an area that has the right kind of mineral stream. But with this little cartridge, you can have these healing waters on tap for over a year or more.
