If you have used your elements:
The method of storage depends upon the length of time that the Black Berkey® Purification Elements will not be used:
If the filters will not be used between 4 to 15 days and you want to avoid the re-priming process, remove the filters from the system, place them into a sealable sandwich bag or container and place the filters in the refrigerator towards the front to ensure that they do not freeze. This will allow the filters to stay mostly saturated so that re-priming is not typically necessary. If for any reason the filters run slower than ususal, re-prime them until the exterior wall of the filter begins to sweat beads of water for 10 seconds.
For long term storage, we recommend drying and sealing the filters. The key is to ensure they are bone-dry before storing them long-term, to prevent any potential bacterial growth. One option for drying your filters is to leave them on a window sill for one to three days and allow them to air-dry. We also 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. Once the filters are bone-dry, place them in a storage bag such as a large, seal-able 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 re-use your filters, clean them by scrubbing the outside with a Scotch-Brite® pad or stiff brush. Then re-prime the filters either manually or with the Black Berkey Primer™ before putting them back in the system.
In theory, the shelf life of the Black Berkey® Purification Elements is indefinite.
**Please note that the storage methods above apply to the Black Berkey® Purification Elements only.
If you have never used your elements:
If the elements are unopened and in their original packaging, please ensure you do not store the elements in an area that also has strong smells to them, such as a laundry room or garage. The elements have carbon as one of their components so it is possible for them to absorb the odors of the room they are stored in. For example if they are stored in a laundry room, it is possible for the media in the elements to pick up the odor of highly fragranced items such as powdered laundry soap.
** When storing the chambers of your Berkey® system, it is best to empty both chambers before storing them, because anytime water is still, it becomes stagnant and can produce bacteria. We recommend washing your Berkey® system with soapy water before leaving it to dry.
