1- If you have already used your filters

The storage method will vary based on the duration for which the Black Berkey® water filters will be out of use:

- If the period of non-use is less than 3 days, no special action is required.

- If the period of non-use is more than 3 days and less than 15 days and you want to avoid the re-priming process, remove them from the system, place them in a sealed plastic bag, and store the filters in the refrigerator, ensuring that they do not freeze. This will keep the filters saturated with water and avoid re-priming. If you find that they are filtering more slowly than usual when you put them back into use, re-prime them until water droplets form on the outside of the filter walls.

- For longer-term storage, we recommend drying and sealing the filters. The most important thing is to ensure they are completely dry before storing them to prevent bacterial growth. One way to dry your filters out completely is to leave them on a windowsill for one to three days. We also offer a priming and purging device called the Black Berkey Primer™. The advantage of purging the Black Berkey® purification elements is that they dry very quickly. When the filters are dry, place them in a tightly sealed plastic bag. Black Berkey® filters are extremely powerful and can absorb odors and smoke in the air. When you are ready to use them again, clean them by scrubbing the exterior with a Scotch-Brite® pad or a stiff brush. Then re-prime the filters manually or with the Black Berkey Primer™ before placing them back in the system.

** Please note that the above storage methods apply only to Black Berkey® purification elements. See below for PF-2 filters.

2- If you have never used your filters

If the filters are unopened and still in their original packaging, be careful not to store them in an place with strong odors, such as a laundry room or garage. The elements contain activated carbon, which allows them to absorb odors from the storage area. Avoid storing them near highly scented items such as soap or laundry detergent.

In theory, the shelf life of Black Berkey® purification elements is limitless.

When storing the stainless steel tanks of your Berkey® system, it is best to empty them completely, as stagnant water can harbor bacteria. We recommend washing your Berkey® system with soapy water before allowing to dry.
