Coldstream FTO+ Ceramic Filter

These filters combine an outer ceramic layer with an activated carbon core. Together, they remove a wide range of contaminants: chlorine, fluoride, heavy metals, pesticides, PFAS, microplastics, viruses and bacteria. All without electricity, purely by gravity.

Two technologies in one

The ceramic physically blocks bacteria, viruses, microplastics and fine particles. The activated carbon then reduces fluoride, heavy metals, pesticides, herbicides and PFAS. The result: clean water with a natural taste that retains essential minerals.

An economical 2-in-1 filter

It replaces both Black Berkey and PF2 filters, simplifying maintenance and reducing overall cost. Each cartridge filters up to 1,500 litres — approximately 6 months of daily use.

Compatible with most gravity systems

Berkey, ProOne, British Berkefeld, Doulton and similar models. It works equally well at home, in the office or in the field — used by NGOs in areas without access to safe drinking water.

The FTO+ filter is designed for tap water, but can also treat certain untreated water sources: well water, spring water, and under certain conditions, surface water such as rivers or rainwater. Highly turbid water may require pre-filtration. Seawater and industrially polluted water are not compatible. Learn more about compatible water sources →
