Fluoride Reduction Water Filter Cartridge
This Fluoride Reduction water filter cartridge is for use in the Triple Under Sink water filter system or as a prefilter cartridge with the Alkaway UltraStream
The media in this filter is made from the same material as rubies and sapphires and successfully removes fluoride from your water (up to 80%). This material will not harm those persons with Thyroid issues.
The material in this pre-filter removes fluoride through a chemical reaction with the media; thus the removal is not dependent on ion exchange*.
The process is slow 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.
It is estimated that at 1ppm fluoride in the water the filter will cope with approx 1800L before needing change.
Additionally, the filter is excellent for 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 feed water. Increasing temperature increases capacity while increasing TDS decreases capacity.
Dissolved lead is absorbed 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.
