Our refillable inserts with INDION RS-F de-ionising resin are for use with drinking water systems to remove fluoride and ensure safe levels. Designed for use in one of our filter housings, it can be used in an under-sink drinking water system or as a pre-filtration stage for reverse osmosis water filtration. The media is comprised of opaque off white beads that attract the negatively charged fluoride ions. This is perfect for people concerned about fluoride intake.


Resin performance varies on external factors in the water supply such as temperature, pH, water quality, flow rate and TDS. We would recommend changing the cartridge every 6 months to a year. If you need more specific advice based on local water supply, please don’t hesitate to get in touch via phone (01507 524576), email ([email protected]), or on one of our social media channels.




Flouride has a mitigating effect against dental caries at safe levels. Excess levels of fluoride (>1.5mg/L) are harmful to human health if consumed in drinking water, leading to dental fluorosis, or skeletal fluorosis at worse. The desirable amounts of fluoride in drinking water is 1.0mg/l.




INDION RS-F is specifically designed to target and eliminate fluoride from potable water sources with fluoride content up to 20 ppm maximum. The resin also performs in the presence of common anions like sulphates and chlorides. Life of the resin is 2-3 years and can be disposed safely in landfill.
