What Can Your Black Berkey Water Filter Elements Do?

You've already probably heard that the Black Filter Elements from Berkey are more powerful than any other gravity filter element currently available. These Black Berkey Filter Elements have a unique purification capability that is due to their unique structure. The micropores within the Black Berkey®Elements are so small that viruses and pathogenic bacteria are simply not able to pass through them.

Although a lot of other water filters on the market may claim to be a water purifier, it does not mean that they were able to meet the performance specifications required for this classification. In order to be classified as a water purifier, a water treatment device must remove at least 99.9999% of pathogenic bacteria and reduce viruses by 99.99%. The Black Berkey®Purification Elements can be classified as water purifiers because they remove 99.9999% of pathogenic bacteria and 99.999% of viruses, which greatly exceeds the standard. The Black Berkey®Purification Element formulation has been tested by State and EPA accredited laboratories to exceed NSF/ANSI Standard 53.

How to Prime the Black Filters

How to Prime Berkey Filters with a Priming Button

The Berkey Priming Button is a thick tan washer that is included with all systems and filters. It funnels water into the filter media flushing out air and manufacturing dust, priming the filter when used with either of the Berkey Filter

How to Prime when water pressure is not available

This process allows for Berkey Black Filters to be primed overnight in a container, such as the bottom chamber when you don't have access to water pressure or have problems priming with water pressure, this is also known as the soak method.

How to Clean the Black Filters

Cleaning the water filter is needed when the flow rate decreases and the output slows to the point that it is no longer meeting your needs. This point depends on the amount of contaminants you are removing. For household use we suggest cleaning every six months, and for field use weekly, possibly daily in the harshest conditions. As part of a regular maintenance routine, our black filter elements can be cleaned up to 100 times before the need to purchase a replacement.

How to Clean your Berkey Earth Filtration Elements
