Fluoride Reduction Filters

Fluoride Reduction Activated Alumina Crystal filter

  • More Details

The material in this prefilter removes fluoride through a chemical reaction with the media; thus the removal is not dependent on ion exchange.  Ion Exchange filters are often presented as fluoride filters. Unfortunately, although they do remove up to 60% of the fluoride from drinking water, they store it and once ion exchange reduces through usage, all the stored fluoride will be re-released into the water.

Note: Requires Pre-filter housing
         May be added to existing standard 10" filter systems.

The filter contains specially processed natural Crystalline Activated Alumina to reduce fluoride in source water.  The cartridges are designed to perform at slow controlled flow rates to ensure maximum performance by the media.

The filter will last up to 2500 litres - at least six months in normal family use.

Cartridges contain a natural aluminum oxide that is specially processed to have a minimum of fines and other foreign matter.  The material removes fluoride through a chemical reaction with the media, thus the removal is not dependent on ion exchange.

The material has a uniform particle size similar to ion exchange resins. It has minimal shrinkage or swelling and low pressure loss. It is physically stable and can be used over a wide pH range.

Fluoride is removed by a chemical reaction with the media. The process is flow and pH sensitive. The best results are obtained when the flow is limited to 1gpm/cu.ft and the pH is held at 5.5. Higher flows and higher or lower pH causes a loss of capacity.
Up to 98% of fluoride is removed.

It is estimated that at 1ppm fluoride in the water the filter will cope with approx 2500L before needing change.

Additionally, the filter is excellent at removing arsenic and lead.

Arsenic removal - is very pH sensitive and capacity decreases rapidly when the pH is below 5.5 or above 6.  Arsenic removal is also affected by temperature and by the TDS (total dissolved solids) of the feedwater. Increasing temperature increases capacity while increasing TDS decreases capacity.

Dissolved lead is adsorbed by the media.  Capacity for lead is at least 0.4lb per cu.ft while maintaining greater than 98 percent lead removal. This process is not dramatically affected by flow rate, temperature or TDS. However, pH should be maintained above 6.0 as lead removal drops under acidic conditions and below 10 as lead precipitates under basic conditions.

Fluoride Reduction Filter including Housing, Fittings, Cartridge & Spanner

  • Description

Easily Install inline between your water source and your ioniser or most other water filters.

For most water filters & water ionisers that use 1/4" hose the QuickFit fittings mean no tools required.

For Nifty Thrifty, Masterpiece, Mavello & Microlite water ionisers a screwdriver is needed to install. 

Just cut your present in-line hose where you want the prefilter to site, and connect to the prefilter.

A five minute job.

The spanner makes changing the cartridge easy.
