Coldstream CF163W Ceramic Gravity Water Filter | Replacement for Wrekin Water WSSD-FL, Doulton, British Berkefeld, Big Berkey & Propur

The Coldstream CF163W is a ceramic gravity water filter cartridge that fits directly into the Wrekin Water WSSD-FL, Doulton (British Berkefeld), Big Berkey, King Berkey, and Propur Big/King gravity filter housings, removing bacteria, cysts, heavy metals, and up to 97% of fluoride without power or plumbing. 

The CF163W uses the same 2.9" x 8" ceramic candle format as the filters supplied with the Wrekin Water WSSD-FL, making it a direct drop-in alternative — so you can run either the standard Wrekin ceraULTRA FTO filter or the Coldstream CF163W in the same housing, whichever suits your budget or filtration preference.

Unlike systems that need a separate fluoride cartridge (such as the PF-4 or PF-2 filters used with Doulton Super Sterasyl or Berkey Black Elements), the CF163W handles fluoride, hormone, and pharmaceutical reduction in a single filter — freeing up space in your lower chamber for more stored water and cutting the cost of running a two-filter setup.
