Our ceramic under-sink water filters work by being connected to your main cold water supply, and the filter unit, which is hidden away from sight, works to remove contaminants from the water so that when you turn on the tap, you get drinking water that is 99.99% plus contaminant-free! The filter candles sit within the system to trap particles, and contaminants that could be found in your regular tap water. This can include chlorine and various bacteria.
Our long-life filter candles can be left to do their work without you thinking about them, until they are due to be replaced, approximately every six months. With our unique BioTect® technology, to inhibit microbiological growth within the ceramic candle, this is one of things that makes our ceramic under-sink filters so effective for so long. Choose the right replacement candle for your Doulton® ceramic under-counter water filter to keep on enjoying healthy and great tasting water at home, for you and all the family.
