Product Description

 FluorEX Max Filter

 Revolutionary Technology offering most effective removal of fluoride.

 Non detectable levels at beginning of filter life

 2000litres capacity

 It is an ALL NATURAL, ALUMINA-FREE filter !

fluoride-free-pre-filter-for-ionizers-w.jpgWe 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 ... which would require an additional secondary KDF filter (for heavy metals) to remove.

This FluorEX Max is all natural and leaves healthy minerals like calcium and magnesium in the water, and it wastes no water (not like Reverse Osmosis systems)

Removal rate: Ionza independently tested the water samples taken from Auckland City to verify the fluoride extraction and its performance. Tested by Hill Laboratories in Hamilton: Fluoride content in water sample less than 0.05g/m3 = non detectable, see test results attached. 

Removal rate at beginning of cartridge usage is 99%, after 2000 litres usage approx 90-95%*

*depending on water source and whether a Carbon/Kdf filter is installed as prefilter - see Active Pure Xtra filters: 2 year capacity or 3yr capacity filter

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. Follow this link for more information: >> Water flow meter

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.

It is most effective when a carbon filter is installed in front to remove heavy metals, so it protects the capacity of the FluorEX Max filter to focus on fluoride predominantly.

Test result Fluoride sample 1 = FluorEX-Max filter:


 Auckland City Tap-water has approx 0.78g/m3 fluoride content.

After the FluorEX Max filtration the fluoride content in the water was reduced to less than 0.05g/m3 (test result) being non-detectable.



A) Due to the nature of the structure of this cartridge, it should not be placed after any mineral filter as the minerals may clog it.

Note: 1. It is highly recommended to place our Active Pure Xtra Filter (High Performance Active Carbon and KDF filter) before the FluorEX-Max to ensure that the FluorEX-Max cartridge is not inundated and competing for absorption of various other chemicals and is thereby free to function optimally for fluoride ion removal for longer period of time.

2. Many filtration systems on the market do not properly regulate the water flow, which is crucial for proper filtration to occur. If your water 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.

B) The Active Pure XTRA pre-filter needs to be flushed first before the Fluorex Max filter is installed. This is so the carbon fines from the XTRA filter do not clog the FluoreEX Max.
After flushing the XTRA filter then the FluorEX Max filter can be installed and flushed. This is very important for the customer/installer to understand.

Initiate Flushing of the FluorEX-Max cartridge with cold/cool water. As the first water begins to flow, you may notice some carbon dust passing through. Allow the water to run on full for 10 minutes then turn off faucet.

1) Flush the cartridge for 2 minutes, when it hasn't been used for 2 or more days

2) Never run hot water through the cartridge, as the filtration process will not be effective. Use only cold/cool water.

3) for optimal Results, replace this filter cartridge based on  your specific Fluoride concentration based on 4 litres/day usage for every 12 months, whichever comes first:

a) Fluoride concentration 2.2ppm (=g/m3) Replace every 600 litres

b) Fluoride concentration 1.2ppm (=g/m3) Replace every 1200 litres

c) Fluoride concentration 0.7ppm (=g/m3) Replace every 2000 litres  (= approx Fluoride concentration of Auckland Tap-water)

Check with your local council regarding fluoride content in tap water.

Do not use the FluorEX Max filter without a pressure reducing valve if your water pressure is above 70PSI


The Active Pure XTRA-SL prefilter is a high performance filter, for excellent quality drinking water (FDA approved) for effective chlorine removal, aluminium or heavy metal contamination. It contains two separate purification media. (Pentex product - USA)

The first stage is the versatile KDF oxidation/reduction media which removes heavy metals, trace metals, such as aluminium and lead, plus chlorine, also prolonging the life of the second granular carbon stage.

The second stage is coconut shell activated carbon: removal of chlorine, organics, chemicals, tastes and odours. Very effective in taste improving.

MEDIA: KDF, Granular activated carbon
Filter Mesh size: 5 µ micron

CAPACITY: 17,000 Litres or 20-24 months (depending on source water) - lasts 2 times longer than ordinary filters.
