Osmio Staff Pick as best Gravity Filter on the market

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.

Superior Flow Rate and Filter Volume

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:

    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.

    Very pleased with filters.
    They make tap water taste as good as any bottled water product.
    Good value for money considering the life span of these filters. Many thanks from a satisfied customer.

Product Questions

Hi can anyone tell me, how many litres of water the filters can pass before needing to be changed and must i change all 4 filters each time? If the answer is yes, all 4 filters must be changed, why does osmio water sell filters singularly? When would you buy a single filter? The difference between the Coldstream Sentry FTO+ and Doulton Super Sterasyl would also be helpful. Thanks
