If you are going to be leaving the system unattended for 3-4 days or less, remove the elements from the top chamber and drain out any water within them. Once drained, place them in a sealable bag while the media is still damp and force out any air in the bag. Store the elements in the front of your refrigerator to maintain freshness while not exposing them to the colder temperatures in the back of the fridge. Store the filters this way for no more than two weeks. Re-prime the elements before reinstalling them in your Berkey® System.
If you will be storing your elements for more than 3-4 days, remove the filters and thoroughly dry them. You can do this by either placing them on a windowsill that’s exposed to sunlight for 1-2 days, or by drying them with the Black Berkey Primer™. Once they are bone-dry, store the filters in a sealable bag at room temperature. The elements will have an indefinite shelf-life as long as they are stored this way. Re-prime the elements before reinstalling them in your Berkey® System.
