Over multiple third party tests, we found a reduction of up to 98.4% of Inorganic Fluoride, with at least a 90% reduction even after many thousands of litres running through.

This product’s advertised fluoride reduction of 98.4% applies to the initial test point (0L usage), using an inorganic fluoride concentration of 6.5–6.7 mg/L under controlled laboratory conditions. Internal testing shows that reduction efficiency may decrease over product lifetime. Actual performance will vary based on factors such as water quality, flow rate, and individual usage conditions.

Water2's Fluoride Filter was designed an Add-On to supplement the main Pod 2.0's qualities of chlorine and microplastic reduction, and its sole use will not provide balanced water. It will also not fit onto UK taps on its own.

The Fluoride Filter does not work nearly as well in conjunction with the 1.0 Filter, and therefore we cannot guarantee effective Fluoride reduction.
