✓ The best gravity filters on the market today
✓ Compatible with Clarity unit, Doulton British Berkefeld and Big Berkey Housings
✓ Reduces fluoride to high levels 97% (see test data) without any additional filters
✓ 2.9″ diameter by 8″ length for superior filtration and faster flow rates
The powerful ceramic gravity filter is compatible with all of the Doulton (British Berkefeld) and Big Berkey (and larger sizes) filter housings and makes a fantastic upgrade option as the filters have fantastic 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, both of these require either the PF-4 or PF-2 Fluoride and Arsenic Filters (respectively) which take up space in the lower chamber which minimise the space available for storage of filtered water and adds cost to the process.
