Highest Performance
View all
Test results show that Coldstream products are effective at removing the widest range of contaminants found in water supplies anywhere in the world, and even outperform some reverse osmosis systems, without stripping beneficial minerals from your drinking water.
Enduring British Design & Craftsmanship
View all
Premium materials, thoughtful and responsible design, and a high standard of company ethics are reflected in the build quality and performance of Coldstream water filters.
Coldstream filters are extensively tested to NSF Standards
Coldstream products are rigorously tested to NSF Standards by an independent certified laboratory in the USA against an extensive array of contaminants. Coldstream replacement filters are tested through to the end of service life so that you can see how these filters continue working to a high standard throughout the course of their use.
Use the FTO Plus filters in your British Berkefeld, Berkey or other existing gravity system.
FTO Plus Ceramic Gravity Filters
Buy
The FTO Plus is the BEST filter for use in British Berkefeld, Berkeys, and other gravity systems. Typically used in pairs, they efficiently deliver purified water and sustained protection from chlorine, chemicals, heavy metals, bacteria and fluoride all in one filter (no add-on filter needed) while retaining healthy minerals. No priming required!
Coldstream MAX Stainless Steel Countertop Filter
Buy
Compact stainless steel solution for apartments, and for portable use. Delivers unlimited filtered water on demand for drinking, cooking and washing food. Cleanable interior ceramic filter intercepts most waterborne contaminants.

FAQs
-
Yes! Coldstream FTO Plus gravity filters fit in Berkeys.
-
Yes! Coldstream FTO Plus gravity filters fit in British Berkefeld gravity systems.
-
Yes! The FTO Plus is the most comprehensive filter to use in these compact, portable gravity
filter systems… and the only one to use if short term protection from fluoride is required. -
No.
-
It is recommended that they be replaced within 6 months of first use, per filter.
When 2 FTO Plus filters are being used simultaneously, replace them both within 12 months of
first use. -
No. Coldstream FTO Plus gravity filters do not need to be primed before use.
-
Yes. The limescale will build up on the ceramic filter and inside the housing.
The ceramic filter can be removed, scrubbed under cool running water and reinstalled.
The filter housing can be cleaned with a dilute solution of vinegar and water as needed.
Do NOT use vinegar to clean the ceramic filter. -
There is no comparison because Berkey’s claims are unsubstantiated. Unlike Coldstream,
Berkey failed to provide life cycle gallonages with its test results which are now outdated. -
British Berkefeld Ultra Sterasyl filters are Berkefeld’s most advanced gravity filter. The Ultra
Sterasyl carries NSF certification, but only for reduction of nominal particulate, turbidity, cysts
and lead, and with no life service gallonages assigned. Ultra Sterasyl filters have also been
tested by independent labs for chlorine, VOCs, PFAS (PFOS & PFOA) and pharmaceuticals to
3030L, but only to 1000L for bacteria, and only to 1515L for arsenic, cadmium, iron, lead and
mercury. The UtraSterasyl does not reduce fluoride.
British Berkefeld Super Sterasyl ceramic filters are an earlier, less effective ceramic filter that is
being phased out.
British Berkefeld Ultra Fluoride is tested to 3000L for arsenic, chromium and lead. We have
found no other test data for the Berkefeld Ultra Fluoride ceramic filter.
By contrast, Coldstream FTO Plus ceramic filters have been tested to 3000L for hundreds of
contaminants (including fluoride) by an accredited lab in the USA. See performance data here. -

The Coldstream pressurized systems (Steel MAX and Blue MAX) are installed under your sink or on your countertop beside your sink. They are hooked up to your water line and provide the convenience of unlimited filtered water as soon as you turn on the dedicated tap.
If you own your home, you will probably prefer an under sink installation. See our Coldstream
Under Counter Purification Systems.
If you rent your home, or tend to move frequently, you may prefer the flexibility of the
Countertop Steel MAX which simply attaches to the threaded end of your kitchen faucet. (This
requires that you have a standard, compatible kitchen faucet.)
If you want a more flexible system that is easy to store and transport, can be set up virtually anywhere without requiring hook up to a water line (such as for emergency and back country use), you may prefer to use the FTO Plus ceramic gravity filters in a gravity filtration system. -
The public refers to 'removing' contaminants. Water filtration professionals refer to 'reducing'
contaminants.
Although >99.99% reduction may be accomplished this level of reduction will not be sustained throughout the entire service life of the filter. The gallonage point at which a filter fails to maintain protection at the Maximum Acceptable Concentration (MAC) for a particular contaminant is the point at which a filter cartridge should be replaced...or before this point is reached.
