How can I store my Berkey PF-2™ or Berkey PF-4™ post filter elements after I’ve used them, but before they reach their life expectancy?

As far as we know, the Berkey PF-2™ Elements can be stored in a refrigerator, short term; but definitely don’t store them in a freezer. If you do store them in this manner, we recommend re-purging the Berkey PF-2™ post filter elements, for up to 1-minute each in both directions, before using them again.
