      How often do I need to change the filters?

      We recommend changing your filters every 6 months.

      Can I use Ultra Fluoride filters with Ultra Sterasyl filters?

      We do not recommend combining filters in your British Berkefeld gravity filter system.

      Can I use my British Berkefeld from Doulton filter when traveling or outdoors?

      Certainly! The British Berkefeld Gravity Systems deliver portable water filtration solutions perfect for on-the-go use. These filters maintain a high standard of filtration, so you can enjoy clean and safe drinking water from any tap, no matter where you are.

      Is there a limit to how much water I can filter in a day?

      There is no strict limit to how much water you can filter in a day with a the British Berkefeld system, but the flow rate may decrease if the filter becomes clogged due to heavy usage. Regular cleaning of the ceramic filter element will help maintain a consistent flow rate even with frequent use.

      Where can I find the instructions for installing and maintaining my British Berkefeld filter system?
      How big are the replacement filters for my British Berkefeld® Gravity portable filter system, and what do they filter?

      To filter bacteria, sediment, rust particles, particles, microplastics*, heavy metals (including lead); pharmaceuticals, oestrogen and chlorine, the filter element is 7” (22cm) tall and 2” (5cm) wide, available here.

      *Claims based upon micro test dust filtration testing.

      When I replace my filter in my Stainless Steel Gravity Filter, will I need to replace the housing?

      No, you won't need to change the filter housing - all you need to change is the ceramic filter inside the housing. Find out how here.

      Which replacement filter fits my Stainless Steel Gravity Filter?

      Our Stainless Steel Gravity Filter can be paired with either the Ultra Sterasyl (formerly known as the ATC Super Sterasyl) or Ultra Fluoride filter elements. The Ultra Sterasyl is designed to reduce common contaminants, chlorine and heavy metals within municipal water supplies to significantly improve the taste and odour of drinking water and ensure it is safe for consumption. Ultra Fluoride is designed to reduce common contaminants, chlorine, heavy metals and fluoride within municipal water supplies. We advise using a minimum of 2 filter elements for two people and a family of 4+ should use four filter elements in their gravity filter.

      Please note that you cannot mix the Ultra Sterasyl filter elements with the Ultra Fluoride element.
