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:

Love these filters, but the price has gone up so much I may as well get a whole house filter soon.
Very happy with the filters. Been using these for a while now and I’m a very satisfied customer. Thank you.
We have hard water where we live so we gave Osmio filters a try. They are very effective and our water now tastes like any bottled water that’s available.
We were impressed with the next day delivery service and the quality of the filters at a competitive price.
one of the containers had no lids on and when i picked out of box it fell through and smashed filter . They replaced straight away with out any fuss and they where first class people to buy from many thanks
