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.
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:

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 if you grow food it would be best to send the media to the landfill.
