Coldstream Sentry Replacement Filters 2 pack – 2.9″ x 8″

  • Compatible with Doulton British Berkefeld and Big Berkey Housings
  • Reduces sodium fluoride to high levels 97% (see test data) without any additional filters
  • The best buy of all and MADE IN THE UK
  • 2.9″ diameter by 8″ length for superior filtration and faster flow rates

Made for the all British made Coldstream Sentry Gravity Filter, these powerful ceramic gravity filter cartridges are compatible with all of the Doulton (British Berkefeld) and Big Berkey (and larger sizes) filter housings and make a fantastic upgrade option as the filters have an amazing performance, particularly with regard to fluoride, hormone and pharmaceutical reduction in water. 

In other systems, such as the Doulton Super Sterasyl and Doulton ATC Super Sterasyl or the Berkey Black Elements,  either the PF-4 or PF-2 Fluoride and Arsenic Filters (respectively) are required as add-ons which take up space in the lower chamber and which thereby reduce the space available for storage of filtered water and also adds further cost to the process.

It’s a sound policy to always keep a spare set handy in case of emergency.

Superior Flow Rate and Filter Volume

The Coldstream filters are 1″ longer and nearly 1″ wider and therefore not only contain more filter media resulting in superior filtration, but also much faster flow rates. See how the filters compare in size to the Doulton Gravity Filters:

Disposing of used filters

The filter would need to be smashed the ceramic and media inside should go to rubbish and the plastic ends can be recycled as plastic. Some people use the media and ceramic to compost but I don’t because they can have pharmaceutical and hormone traces and I grow food so I would not want that. For the media, it would be best to send that stuff to the landfill.
