What People Love About AlkaFlow™

Real stories from happy customers who’ve upgraded their hydration and health with AlkaFlow™.

Unlike the generic Black Berkey lookalike filters that are sold on Amazon, the Coldstream filters are made by a reputable company that publishes performance data. And the list of what is removed is very impressive!

Wesley C., United States

I love the fact that the Coldstream FTO+ filters reduce fluoride without the need for additional filters.
This represents a big cost savings.

Carlos P., Canada

According to independent lab tests, the performance after 3000 liters does not drop off much, and most of the contaminants I worry about are reduced by at least 95% or higher. Excellent value, highly recommend!

Charlene K., UK

I purchased these to replace filters in my Royal Berkey. They work beautifully and filter water much faster than the Berkey filters, while still providing great tasting water. There isn’t any smell that I’ve noticed and the taste of the water is clean and fresh.

Hope C., United States

So glad to have come across the Coldstream FTO+ filters. In addition to producing great tasting water, these filters are way easier to install than Black Berkey filters and do not require priming.
