Doulton water filters are ceramic water filters with an activated carbon core. Each filter is compatible with our Doulton under sink and tap-mounted countertop water filter systems. Designed to improve the taste and quality of your tap water, they work by using a natural ceramic material (that acts almost like a sieve) to reduce common contaminants in your drinking water supply, whilst an internal activated carbon core acts like a sponge to further reduce the effects of contaminants in your drinking water. Doulton ceramic water filters also preserve essential minerals that your body needs, leading to healthier, cleaner water for you and your home.

Doulton water filters use natural ceramic technology to remove bacteria, cysts, sediment, and other contaminants without chemicals or electricity. They combine ceramic and activated carbon to improve both quality and taste of drinking water. As the pioneers of water filtration since 1826, the products are still Made in Britain in a manufacturing facility in Staffordshire and frequently go through rigorous internal and external testing to ensure exceptional standards for households around the world. With Doulton you can rest-assured that not only are their products effective, but they also have a UK based customer service team on-hand to help with any questions, queries and guidance.

In the UK our tap water goes through rigorous testing and regulations to provide consistent safety and quality for homes. Therefore, most UK houses would find a Doulton water filter system suitable for their tap water. If you are based in another country, your tap water should still be suitable.
