Gravity Cartridges

Coldstream filters are designed to offer a very high-performance water purification solution that combines convenience and efficiency. Find out in this article why Coldstream FTO+ filters are the best gravity cartridges.

Coldstream FTO+ filters are compatible with all sizes of water purifiers such as Berkey, Berkefeld, ProOne, weeplow (excluding the 5.6 Litre model), Purewell, Phoenix

Coldstream FTO+ cartridges are distinguished by their ability to effectively reduce a wide range of contaminants, including bacteria, viruses and heavy metals, and drug residues, while preserving minerals essential to health, but they are also known for their ability to significantly reduce nitrates and significantly reduce fluoride.

This feature allows users of Doulton Berkefeld systems to no longer have to choose between Super Sterasyl cartridges and those dedicated to fluorine reduction. Coldstream FTO+ cartridges meet both of these needs in a single cartridge, providing an overall better performing solution.

In terms of efficiency, they compare favourably to the famous Black Berkeys, ensuring exceptional water quality for demanding users. With their simple installation and minimal maintenance, Coldstream FTO+ filters are the epitome of water filtration, suitable for those looking to ensure clean, safe and high-quality water for their family or community, while supporting a company dedicated to positive environmental impact and impeccable quality.
