Coldstream's Innovative Technology

Advanced test:

• Coldstream uses an advanced testing method with a scanning electron microscope to measure the presence of contaminants.
• This unique technique often raises questions due to its complexity and importance.

Pore size variability:

• Coldstream filters have varying pore sizes, which sets them apart from standard filters.
• Uses mercury porosimetry to measure this variability, providing efficient filtration and optimal water flow.

Coldstream Manufacturing Method

High Pressure Molding:

• The filters are manufactured via a high-pressure casting process to maximize the filtration surface area while maintaining optimal porosity.
• This method differs from traditional techniques, providing superior filtration performance and extended life.

Comparison with Berkey and other brands

Nitrate reduction : Coldstream excels at nitrate reduction, outperforming other well-known brands like Berkey.

Constant fluoride protection : lColdstream filters maintain a consistent fluoride reduction over six months, providing long-lasting performance not seen in other brands.

Excellent contaminant filtration : rHigh reduction of bacteria, viruses, heavy metals and chemicals, ensuring exceptional drinking water.

Coldstream's Scientific Transparency: A Benchmark in Gravity Filtration

At Coldstream, scientific transparency takes precedence over marketing. This philosophy makes our water filtration systems more serious, honest and reliable than those usually offered on the market.

Why choose Pure Filters equipped with Coldstream FTO+ filters ?

1. The widest filtration panel on the market:

Coldstream FTO+ and CTO Max cartridges cover the filtration of more than 230 rigorously monitored substances, including:

• Viruses (Rotavirus)
• Bacteria
• Parasites
• Heavy metals
• Microplastics
• HAA5 (Haloacetic Acids)
• Volatile Organic Compounds (VOCs)
• Pesticides
• About thirty common medications

These performances are clearly documented in our test sheets made according to IAPMO / ISO 17025 standards. For comparison, competitors generally publish between 60 and 125 parameters tested; Berkey achieves about 125 parameters on a single lab test, while ProOne achieves about 160 substances, but tested on ten times lower volumes of water.

2. Full access to raw data:

Coldstream provides comprehensive and transparent data, with detailed results indicating for each contaminant:

• Initial concentration (influential)
• Final concentration after filtration (effluent)
• Precise reduction rates at different volumes treated (4,000 L, 5,000 L, 6,000 L)

For example, for aluminum: < 1 Âμg/L at 4,000 L, 18 Âμg/L at 5,000 L, 24 Âμg/L at 6,000 L, i.e. a constant reduction of more than 99%.

This data allows our users to verify for themselves the exceptional consistency of performance over several years of home use, a transparency that is unique in the gravity filter market.

In summary:

Coldstream does more than just claim performance of over 99% on small volumes of lab-tested water. We publish all the results obtained in full on realistic and relevant volumes for daily use. This dual requirement, exhaustive coverage of filtered substances and full transparency on raw data, positions Coldstream as the most serious and honest brand in the gravity filter market.
