• How Coldstream Filters Work

The efficient all in one filtration system

The Coldstream Sentry CTO+ ceramic filter consists of two important elements:

The porous ceramic outer layer contains millions of tiny holes – it also contains silver. The holes are so small that bugs and particles are blocked on the ceramic surface but allow water to pass through. Bugs trapped on the surface are killed by the silver, stopping them breeding.

The second, inner core is made from activated carbon and removes chlorine, chemicals and metals. It is specially impregnated to remove lead and mercury as well. This allows only healthy salts and electrolytes through to produce safe, clear water that tastes good too – straight from your tap.

Made in the United Kingdom

All Coldstream ceramic water filters are made in England to the highest standards, using advanced manufacturing techniques to deliver safe, great tasting water time after time.
