FAQ – FILTER ELEMENT STORAGE LIFE

HOW SHOULD I STORE MY BLACK BERKEY® PURIFICATION ELEMENTS AND HOW LONG IS THEIR SHELF-LIFE?

It is best to empty both chambers before storing your Berkey® system because anytime water is still it becomes stagnant, which means it could produce bacteria. We recommend washing your Berkey® system with soapy water before leaving it to dry. If you have used your elements,  you should fully dry them before storing. We offer a tool to assist in both priming and purging. This tool is called a Black Berkey Primer™.  The benefit to purging the Black Berkey® Purification Elements is that they are dried very quickly. Another option for drying your elements is to leave them on a window sill for one to three day and allow them to air-dry. The key is to ensure they are bone-dry before storing them, to prevent any bacterial growth.

For long term storage, we recommend sealing the purification elements. This can be done with a storage bag such as a large sealable sandwich bag. The elements are extremely powerful and can absorb odors and smoke from the air. By sealing them in a storage bag, they should not absorb any odors from the air. When you are ready to use your elements, clean them by scrubbing the outside with a Scotch-Brite® pad or stiff brush. Then re-prime the elements before being putting them back in the system. In theory, the shelf life of the Black Berkey® elements is indefinite.

FAQ – BLACK BERKEY® PURIFICATION ELEMENT SPECIFICATIONS

BLACK BERKEY®PURIFICATION ELEMENTS

 FILTRATION SPECIFICATIONS

Black Berkey® Purification Elements are more powerful than any other gravity filter element currently available.  The Elements have a unique purification capability that is due to their unique structure. The micro- pores within the Black Berkey® Elements are so small that viruses and pathogenic bacteria are simply not able to pass through them.

Many water filters on the market may claim to be a water purifier, but do not 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 99.9999999% 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.

The Black Berkey® Purification Elements have been tested and confirmed to remove or greatly reduce the contaminants listed below:

 

VIRUSES >99.999%
Exceeds Purification Standard (Log 4):
MS2 Coliphage – Fr Coliphage

PATHOGENIC BACTERIA SURROGATE >99.9999%
