Fluoride is very hard to remove from water and usually takes a large scale ceramic filter to do the job fully or a reverse osmosis system.
Public Health England states that around 1 in 10 people in England currently have fluoride added to their water supplies, so it's best to check on your water supplier's website to see if you're affected.
We can't guarantee that our filter removes fluoride fully. For effective fluoride removal a full Reverse Osmosis system would be advised, which can be expensive.
