Stop wasting cash on a fluoride water filter if you live in the UK.
I sell water filters for a living — so here's me telling you that most of you don't need to buy a fluoride one. Most UK tap water is not fluoridated, so buying expensive filtration systems is often unnecessary.
There's a lot of advice online right now pushing everyone towards a fluoride filter. But only about 10% of the UK actually has fluoride added to its water — mainly the West Midlands and the North East. Scotland, Wales and Northern Ireland don't add it at all.
For most people, that's money spent solving a problem you don't have.
Before you buy anything, check your postcode with your local water supplier — or drop us a message and we'll help you find out whether you've actually got fluoride in your water, and what (if anything) is worth filtering for your supply.
Contact the team at Fountain Filters if you need advice on your specific water setup.
Honest advice over an easy upsell, every time. 💧
