Coldstream Sentry 2.9″ x 8″ 4 pack Replacement Ceramic Filters

  • 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.
