Fluoride can occur in drinking water naturally as a result of the geological composition of soils and bedrock. Some areas of Britain have high levels of naturally occurring Fluorine which can dissolve easily into groundwater as it moves through gaps and porous spaces between rocks.
Fluoride can also be added to public drinking water supplies as a public health measure for reducing cavities in teeth among the treated population.
It can help prevent tooth decay, which is why it's added to many brands of toothpaste and, in some areas, to the water supply through a process called fluoridation.
Unlike other filters on the market, Culligan's ZeroWater 5-stage filters have been tested to remove up to 99.9% off all TDS (Total Dissolved Solids) from your tap water.
And unlike competitors, our filters are certified to reduce 99.7% of lead and 95% of the forever chemicals PFOA/PFOS to provide cleaner, healthier drinking water in every sip.
With Culligan ZeroWater, you’ll be left with nothing but the purest-tasting water.
There have been some concerns that fluoride may be linked to a variety of health conditions. Reviews of the risks have so far found no convincing evidence to support these concerns.
However, a condition called dental Fluorosis can sometimes occur if a child's teeth are exposed to too much fluoride when they're developing. Read more about looking after children's teeth and looking after your baby's teeth.
