We recommend that you replace your filter every 6 months. This is to ensure that your water continues to taste great and you can enjoy all of the benefits of removing up to 99.99% of contaminants in each sip. However, you may need to replace it sooner or later, depending on usage. Key
indicators that will determine the frequency of change include:

• Changes in flow rate    
  
• Taste of water changing
  
• How much water you drink
  
• Original water quality

Can I change the filters myself?

Of course you can! This is a simple process that can be done without the assistance of a plumber or other professionals. Simply follow the instructions for the specific water filter system you own.

How to choose the correct replacement filter for your system:

Each Doulton and British Berkefeld filter has a filter name
and unique 4-digit code located on the plastic casing at the top of the filter; for example ‘Ultracarb 9501’. Once you have this information, finding the replacement filter is easy!

Here’s how to verify the authenticity of your filter:

• Consistent Doulton branding on the cartridge,
  packaging, and instruction leaflet     
  
• A visible batch number or serial code
  
• Purchased from an authorised Doulton distributor
  
• Pricing in line with the usual product cost
  
• A clear 4-digit product code
  
• High quality craftsmanship and materials

If you have any doubt or questions regarding the authenticity of your ceramic water filter products or filters, please reach out to filtersales@doulton.com to verify.

Can I use other brands of water filter in my Doulton or
British Berkefeld system?

We do not recommend using any other brands within the
Doulton or British Berkefeld water filter systems. To ensure optimal performance, safety, and certification, always use genuine, approved filters.
