Doulton has been making ceramic water filters in the UK for nearly 200 years. The ceramic is made from natural materials, and has 80% less plastic waste than other available synthetic cartridge filters. Only suitable for a mains pressure supply.
 
During use, contaminants filtered from the water may build up on the outer surface of the ceramic cartridge and cause a reduction in flow through the unit. The cartridge will, therefore, need removing periodically for cleaning to restore the flow.
 
Cleaning frequency will be dependent on the condition of the incoming water. A cartridge that has reached the end of its life would be indicated by a reduction in the quality of the filtered water with respect to taste. The cartridge should be replaced in accordance with the rated service capacity, which would typically give a period of six months usage. BPA free.

Customer Questions
How do I clean a ceramic filter candle?

We recommend a gentle, evenly applied buffing with a scouring pad until the whiteness of the ceramic returns.

Rubber gloves are recommended to be used during cleaning and NEVER use soap or detergents.

Ensure that the end of the plastic mount does not come into contact with unfiltered water.

See how to clean your filter.

Are all ceramic water filters the same?

Absolutely not. Doulton Water Filters are the original ceramic filter manufacturers and a globally trusted brand. We have been updating our groundbreaking filter design since 1826. We are a UK ISO accredited company offering independently and regularly tested water filters. Certifications held with NSF, WRAS, Lucideon and many more.

Does my filter element work with hardness?

Yes, our ON countertop and IN undercounter DUAL systems come with the option of a Limescale specific pre-filter that filters Limescale. Find out more here.

Do I need to sterilise the candle after cleaning?

No, there is no need to sterilise the ceramic candle. All our filters have bacteria inhibiting features built in.

Can I recycle my old ceramic filter?

You can recycle the plastic mount and compost the old filter element or use it to help with drainage in the bottom of your plant pots.


We suggest safely removing the mount using light pressure with a hammer to break it from the filter element. Next, cover the ceramic with an old rag and gently break it into small pieces, again using light pressure with a hammer. Find out more here.
